A common mistake in this category is buying a deadbolt smart lock for a door that slides. A deadbolt throws a bolt straight into a strike plate 90 degrees from the door face, and a sliding door has no strike plate to receive it. The hardware that works on a sliding door looks completely different: a surface-mounted electronic unit with a horizontal latch that drives into a track or a mortise body cut into the stile. That is why searching for the best smart locks for sliding doors produces so much dead end after dead end, and why fit comes before features in every recommendation below.
We spent weeks working through this category line by line, and the honest headline is that sliding door smart locks are not a polished corner of the market. The best average any dedicated mortise slider lock here reaches is 4.0, and the only locks with a meaningful review base sit between 3.7 and 4.0. That is the realistic bar for the whole category, not a problem with our shortlist. Once you accept that, the picks become straightforward: measure first, then pick the lock whose thickness range and latch type match your door.
Twelve locks made the cut. They cover the three door families that actually exist in this niche: mortise-style patio sliders with a 2085 or 2885 lock body, frameless glass doors that clamp on without drilling, and narrow-stile aluminum sliders that need a slim 36mm lock body. A few picks come with built-in Wi-Fi and a phone app, others are Bluetooth only, and one combines a fingerprint reader with a camera. If you are still choosing between deadbolt options, our guides to the best smart locks for front doors and the best smart locks for apartments cover the applications that need one.

1. Eseesmart Sliding Glass Door Lock – Best All-Round Mortise Slider Lock
Sliding Glass Door Lock, Eseesmart Sliding Door Smart Lock with Fingerprint Code Keypad RFID Card Bluetooth App Key, Electronic Digital Biometric Keyless Entry Patio Door Lock with Handle
Fits 22-120mm doors
IP65, -13F to 149F
Up to 300 user profiles
Up to 8 months on batteries
Pros
- Purpose-built mortise slider lock with a matching pull handle
- Five unlock paths including app
- RFID card and a mechanical key
- IP65 sealing across a -13F to 149F operating range
- Reversible handle fits either sliding direction
Cons
- Bluetooth only
- so remote unlock needs an extra gateway
- 4.0 average with 12% one-star ratings
- Needs a compatible 2085 or 2885 lock body
This is the lock we would put on our own patio slider. It arrives as a complete set: a mortise lock body, the exterior and interior panels, a pull handle, two RFID cards, two mechanical keys and a screwdriver. That completeness matters, because the alternative is bolting a keypad onto existing glass and hoping the latch behind it lines up.
Fit is the standout. The stated thickness window runs from 22mm to 120mm, one of the wider ranges in this roundup, so it covers a standard wood or vinyl framed slider as well as a beefier aluminum door. The handle assembly is reversible, which removes the single most common install mistake on a slider, fitting the interior and exterior panels to whichever direction the door opens.
Weather sealing is specified at IP65, and the operating range is listed from -13F to 149F. On an exterior patio door in a cold climate that is the number that matters, since finger sensors and LCD keypads both get sluggish when the cells sag in low temperatures. The lock is rated for 15,000 lock and unlock cycles and a 250 lb load test, and it carries an anti-tamper alarm.
The compromise is connectivity. It runs on Bluetooth, so the app works when your phone is in range and remote unlock from across town needs a separate gateway. Battery life is listed at up to eight months, with a low-power warning and a power bank emergency input when the cells die.
What it fits and what it will not
It needs a mortise-style door with a compatible 2085 or 2885 lock body. If your slider is a frameless glass unit held together by clamps, this is the wrong lock and you want one of the clamp-on models further down. Check the interior edge of the door for an existing latch plate before you order, and measure the stile width, since the panel needs roughly 45mm of frame to screw into.
Capable of storing up to 300 user profiles, this is the pick for a busy rental or a household where a lot of people come and go. For a two-person home on a single slider, you are paying for capacity you will not use.
Where the 4.0 average comes from
Reviewers like the hardware and the range of unlock methods, and the ranking in sliding door hardware reflects real category demand. The score sits at 4.0 with 12% one-star ratings, and the complaints cluster around connectivity and fit rather than the fingerprint reader, which is described as fast.
The lesson is straightforward: confirm your door has a mortise latch before buying, and decide now whether Bluetooth-only is enough for how you use the door. Get both right and this is the safest purchase in the group.
2. Anweller 2885 Mortise Sliding Lock Set – Best Value With Hub-Free Wi-Fi
Anweller 2885 Mortise Sliding Glass Door Lock, Smart Fingerprint Code Keypad RFID Remote App Electronic Digital Biometric Safety Patio Door Double Hook Mortise Lock Set with Handle
Hub-free Wi-Fi remote
2885 double-hook mortise
90-second lockout
Fits 22-120mm
Pros
- Wi-Fi remote unlock with no separate gateway needed
- Double-hook 2885 mortise adds real resistance to forcing
- Lockout after five failed attempts plus a tamper alarm
- Complete set with handle and two RFID cards and two mechanical keys
Cons
- 3.7 average with 19% one-star ratings
- Aluminum and zinc body feels light next to stainless models
- Needs a compatible mortise and a frame at least 45mm wide
This is the best-documented lock in the roundup, with 43 ratings, which makes its 3.7 average a score you can actually plan around. Where locks with one or two reviews are a gamble, this one has a large sample telling you exactly what to expect: solid electronics, generous features, and fit that depends on your existing mortise.
What separates it from the rest is the built-in Wi-Fi. Most locks in this price area are Bluetooth only, and owners routinely discover that a supposedly smart lock has no remote range. This one connects to an app over Wi-Fi directly, so you can unlock the patio door from work or share a code with a guest standing at the door.
The lock body is the 2885 double-hook type, the configuration that reaches into the top and bottom of the sliding track. On a double-panel slider that grabs two points, which is a meaningful step up in security over a single hook. It also shuts down for 90 seconds after five invalid code or card attempts and carries a built-in tamper alarm.
Fit runs from 22mm to 120mm, and the frame must be at least 45mm wide. Battery life is listed at up to eight months with a low battery reminder and a power bank backup input, and the manufacturer backs the set with a 12-month warranty.
Why the Wi-Fi detail decides it for rentals
For a short-term rental or a multi-unit property, remote unlock and temporary codes are the whole point of the purchase, and this lock delivers them without asking you to add a hub to the invoice. Codes can be issued from the phone, and a guest never needs the physical keys that usually go missing in a rental.
The trade is the lockout feature. Five bad attempts triggers a 90-second freeze, which is a sensible anti-guessing measure and a genuine annoyance if your household includes a child repeatedly guessing at the keypad. Disable it in the app before handing out the lock if that applies to you.
What the 43 reviews reveal about build
Owners credit the feature set and the hub-free connection, and the recurring gripes are about weight and material. The body is aluminum and zinc rather than the 304 stainless steel used by the better models, and several reviewers describe it as feeling light in the hand compared to a stainless set.
That said, security here comes from the double hook and the lockout logic, not from the case material. If your door is a standard mortise slider, this is the pick with the most evidence behind it.
3. NGTeco Smart Glass Door Lock – Best Budget Clamp-On Lock
NGTeco Smart Glass Door Locks, 5 Unlock Ways Keyless Entry Gate Locks, Remote Control, Fingerprint, IC Card, Password, No Drill Door Locks for Home,Green House,Cabinet,Office
No-drill 10 minute install
1000 permission sets
10000 unlock logs
4 AA for up to 6 months
Pros
- Lowest cost in the group with a 4.5 average and 66% five-star ratings
- Drill-free install in about 10 minutes with no damage to the glass
- Reviewers confirm the fingerprint and keypad and RFID all respond quickly
- Bilingual voice prompts with English selectable out of the box
Cons
- One reviewer doubts it holds up in genuinely wet outdoor conditions
- Adhesive-only mounting gives limited real security
- Accented voice prompt is hard for some buyers to understand
- Fit range is not very adjustable
The electronics in this lock are the best value in the group, and several reviewers independently confirm that the fingerprint reader, keypad and RFID card all respond quickly. The 4.5 average comes with 66% of ratings at five stars, which is a genuinely positive signal on a 15-review base.
Installation is the strongest part. The unit clamps on without drilling in roughly ten minutes with no professional tools, so a frameless glass door keeps its warranty and its appearance. That no-damage approach also makes it reversible, which is the only sensible choice if you rent.
Five unlock paths cover fingerprint, a password that includes a virtual anti-peep mode, IC card, remote control and a doorbell function. Storage is where it outclasses everything else here: up to 1,000 permission sets and 10,000 unlocking records, which is the sort of capacity a small office needs.
It runs on 4 AA alkaline batteries for up to six months, with a low battery reminder and emergency power from a power bank. It fits frameless glass doors 100-120mm thick with a door frame width of 66mm or more, so check those numbers against your door before you commit.
Where this lock genuinely belongs
Judging it as a barrier for an exposed exterior slider would be a mistake. Several owners describe it as an interior showcase door, cabinet or hutch lock, and for those jobs the feature set, the credential capacity and the easy clamp mount make it excellent value. For a bedroom slider, a home office, or a secondary interior glass door, this is a strong buy.
The weakness is honest and structural. The mount is adhesive rather than bolted, so it does not add meaningful forced-entry resistance, and one reviewer openly doubts the electronics tolerate sustained wet outdoor exposure. Pair it with a door security bar if it is on a real entry.
Check the frame width before ordering
The 66mm minimum frame width rules out a lot of narrow doors, and the fitting is not very adjustable, so a wrong guess here is an easy return. If your glass is thicker than 120mm or your frame is under 66mm, move on.
Two fixes worth knowing: some models in the same line add AI fingerprint learning for repeat fingers, and the English voice prompt is selectable at setup even though the default language is Chinese.
4. Yale Assure Lock Keypad for Andersen Patio Doors – Best for Andersen Owners
Yale Assure Lock Keypad for Anderson® Patio Doors Handle with Wi-Fi, Black
Keypad with no key cylinder
Wi-Fi and Bluetooth
9V battery back-up
Alloy steel construction
Pros
- Purpose-built hardware for Andersen patio doors
- One Touch keypad locking with no cylinder to lose
- Built-in Wi-Fi and Bluetooth with app monitoring
- 9V battery back-up for power outages
- Works with Alexa
- Google Assistant and Siri
Cons
- Narrow compatibility limited to Andersen A-Series and E-Series
- 3.6 average with roughly one in four ratings at 1 star
- Panel measures 1.1 x 1.9 x 12 inches for a full patio door
Every other lock in this roundup asks you to check that it fits. This one asks you to check that you own the right door. It is engineered for Andersen patio doors, and that specificity is either exactly what you need or a non-starter.
If your slider is an Andersen A-Series or E-Series patio door, this is the only pick here with brand-backed fit. The unit comes with the lock, mounting hardware, levers, a Bluetooth module and a connect bridge, and the whole assembly is alloy steel. That is a meaningfully different proposition from an unbranded mortise lock of uncertain compatibility.
Entry is by keypad, with One Touch locking that secures the door by tapping rather than re-entering a code. There is no key cylinder at all, which removes lost keys and removes pick and bump entry as an option. Bluetooth and Wi-Fi both run through the Yale Access app for remote monitoring, and it works with Alexa, Google Assistant and Siri.
Power is backed up by a 9V battery contact, so a flat battery or a power cut does not lock you out of your own patio door. That single feature is worth more to most households than any access method.
When the rating is an installation problem, not a product problem
The 3.6 average with roughly one in four ratings at 1 star comes almost entirely from fit and installation friction on specific door brands. Buyers who confirm compatibility tend to rate the convenience, the app and the battery backup highly. Buyers with the wrong door do not.
So the process is simple: identify your door manufacturer and series from the label on the frame, and confirm against the manufacturer list before ordering. If it is an Andersen A-Series or E-Series patio door, this lock removes the single largest risk in the category.
Who should skip it
If your slider is vinyl, aluminum, or a frameless glass unit, compatibility ends here and your money is better spent on a lock designed for your door type. You also pay a premium for that guaranteed fit, so it only makes sense when compatibility is settled rather than assumed.
App stability is a fair question for any lock. Yale is a long-established brand with an established app, which answers the vendor longevity worry that some owners raise when considering no-name smart home hardware.
5. eLinkSmart Slim Mortise Lock – Best for Narrow Aluminum Frames
eLinkSmart Slim Keypad Door Lock Built-in WiFi Fingerprint Keyless Entry Mortise Smart Lock for Sliding Patio Glass Door, 2885 Hook Latch, Fits 22–110mm (0.87″-4.33″) Door Thickness, Tuya App
Fits 22-110mm with 5 adapters
36mm slim lock body
Built-in Wi-Fi and Tuya app
All-steel dual hook
Pros
- Widest fit range in the roundup with five adapter sets covering 22-110mm
- Narrowest lock body at 36mm for slim aluminum patio frames
- Hub-free built-in Wi-Fi with temporary and scheduled codes
- All-steel dual-hook latch instead of a plastic hook
- No-drill install in 10-15 minutes with a screwdriver
Cons
- 3.3 average with 26% one-star ratings
- Several reviewers report the lock does not appear in the app so wireless features fail
- Instructions are sparse and one buyer got a wrong cutting template
- Hook needs a keypad confirmation step before it engages
This is the dimensional answer to the narrow-frame problem. The lock body measures 36mm wide and the minimum frame width is 40mm, which is slimmer than anything else in the group, and five included adapter sets let the mortise expand from 22mm all the way to 110mm of door thickness.
It also has built-in Wi-Fi connecting straight to the Tuya app, so remote unlock works without a separate hub, and one-time, temporary and scheduled codes are all supported. The latch is an all-steel dual hook rated for forced entry resistance, which is a real step up from the plastic hooks on cheaper slider locks.
Installation is advertised as 10-15 minutes with a screwdriver and no drilling, and the manufacturer backs it with a 30-day return window and a 180-day free exchange for defects. Battery life is listed at up to 12 months on 4 AAA cells, the longest claim in the roundup.
On paper this is the most capable unit here. The 3.3 average with 26% one-star ratings says the paper and the reality sometimes disagree, and understanding why matters more than the score.
The two failure modes to test for
Fit is the first. Reviews specifically mention standard Jeld-Wen and Canadian sliders not working, so measure your existing latch before you order. The 22-110mm range is genuinely wide, but the frame width and the mortise body still have to be right.
Pairing is the second. Several reviewers report that the device does not appear in the app, which leaves the RFID and wireless features unusable even though the keypad and fingerprint still work. That is a firmware or account problem rather than a hardware one, and support responsiveness is criticised alongside it.
What the extra latch step really means
The hook requires a keypad confirmation step before it engages, and some buyers read that as a security gap. The reasoning is fair: if the door locks only after a deliberate tap, a door that swings open on its own stays open. Test the auto-lock behaviour in the app before you rely on it.
Despite the rating, this remains the correct choice for a slim aluminum patio frame. Only the Swokely comes close, and it needs a different lock body entirely.
6. Perfiware LG2315 Glass Door Lock – Best for Frameless Swing Glass Doors
Smart Glass Door Lock,Perfiware 4in1 Biometric Fingerprint Glass Door Locks LG2315,2024 Drill-Free Keyless Entry Upgraded Door Locks,Great for Office,Home,Hotel,Apartment
Fits 10-12mm glass
No-drill one-piece mount
100 users and 100 prints
Four unlock methods
Pros
- Fast
- accurate fingerprint reader with 100-fingerprint capacity
- Four unlock methods including a virtual password and a remote
- Drill-free one-piece install that leaves the glass unmarked
- Auto-lock and constant-open modes both built in
Cons
- Built for push-pull frameless swing doors
- not a sliding track lock
- Narrow fit window at 10-12mm door thickness
- 4 AA batteries are not included
A word of clarity first, because the listing title is easy to misread. This is a lock for frameless glass doors that swing or push-pull. It is not a sliding track lock, and no amount of adjustment will make it one. If your door slides, jump ahead to picks 1, 2 or 5.
For a frameless glass door, though, it is excellent. The 4.5 average comes with 80% five-star ratings across 25 reviews, and owners consistently report straightforward installation and reliable fingerprint scanning.
The construction is a one-piece drill-free unit that clamps to the glass without marking it, so there is no risk of cracking a tempered panel or voiding a warranty. Dimensions are 4.33 x 2.87 x 7.28 inches and the listed weight is 3.63 pounds, so it is a substantial fixture rather than a clip-on gadget.
How much it can hold
Storage covers up to 100 users, 100 fingerprints and 100 cards, plus 10 programmed remotes with 3 fingerprints each. That is generous for a home and adequate for a small office, though it is a fraction of the 1,000 permission sets the NGTeco holds.
Access methods are fingerprint, a 16-digit virtual password, IC card and remote control. The virtual password is the interesting one: it lets you create a numeric string that is not the real code, so a shoulder-surfer watching you enter a code learns nothing.
The fit window is the whole story
This lock requires a door thickness of 10-12mm and a two-glass-door gap of 0.16-0.59in. Measure both before ordering, because glass door thickness varies widely by manufacturer and there is no adapter set to compensate.
Two operational notes. Auto-lock on closure and a constant-open mode are both available, selected by long press, and emergency power comes from a portable charger during an outage. Batteries are 4 AA and are not included, which is a small annoyance on an otherwise tidy package.
7. Perfiware LG2215 Biometric Glass Lock – Best for Greenhouse and Cabinet Doors
Smart Glass Door Locks,Perfiware Biometric Fingerprint 4in1 Glass Gate Locks LG2215,No Drill Keyless Entry Door Locks,Great for Home,Window,Front Door,Green House,Cabinet,Office,Hotel
Fits 10-12mm glass
Steel deadbolt, plastic body
Self-adhesive no-drill mount
100 users, 10 remotes
Pros
- Reviewers report straightforward installation with firm self-adhesive mounting
- Fast fingerprint reader and an app that loads without issues
- Auto-lock removes the need to remember to secure the door
- Remote fob unlocking is more convenient than fingerprint alone
Cons
- Much of the lock body is plastic around a steel bolt
- Marketed for push-pull frameless glass doors rather than a sliding track
- Narrow fit window at 10-12mm door thickness
This sibling of the LG2315 carries the strongest average among the locks here with a meaningful review base, at 4.6, with 73% of ratings at five stars. The base is small at 13 reviews, so read that with proportion, but the pattern in the reviews is consistent and specific.
Owners like the self-adhesive mounting, which grips firmly without tools or drilling, and they report the fingerprint reader responding quickly with the app loading reliably. The remote fob is singled out as more convenient than fingerprint alone, which makes sense for a greenhouse or a cabinet where a wet or gloved hand is common.
Access is the same four-way mix as its sibling: fingerprint, 16-digit virtual password, IC card and remote, with up to 100 users, 100 fingerprints, 100 cards and 10 remotes at 3 fingerprints each. Auto-lock on closure, a constant-open mode and long-press manual locking are all present, and a portable charger will power it through an outage.
The box is unusually complete: main and sub locks, side strip, sticky plate, IC card, remote control and instructions. The sub lock matters if you have a double glass door, since it secures the second panel.
Best used where the door is not your front door
A greenhouse, a garden store, a wine cabinet and a workshop door are the natural homes for this one. The self-adhesive mount is the deciding feature in those settings, because the glass may be tempered, already drilled, or a distance from any power source.
For an exposed exterior entry it is the wrong tool. Adhesive alone will not resist a determined push, and there is no weather rating in the listing for sustained outdoor exposure on a security-critical door.
One criticism worth taking seriously
One reviewer points out that most of the lock body is plastic apart from the steel deadbolt, which weakens the perceived strength of the unit. That is a fair description of this whole weight class, and it is why the stainless steel options exist.
Fit is again the deciding number: 10-12mm door thickness, a two-glass gap of 0.16-0.59in, and a panel with a 7.28in long side. The reversible design covers single and double opening configurations.
8. Perfiware LG75TY Sliding Lock with App – Best for Short-Term Rentals
Perfiware Sliding Glass Door Lock LG75TY with APP,Smart Fingerprint Keypad Pin Screen Sliding Door Locks,Keyless Safety Lock for Sliding Door,Great for Office,Hotel,Apartment,Patio,Barn,Front Door
App unlock with doorbell request
Needs a frame over 2.87in
100 users and 100 prints
5 unlock methods
Pros
- Genuine remote app unlock with a visitor doorbell request on a framed sliding door
- Main plus secondary lock covers double-sided framed sliders
- High-load stainless steel construction with corrosion resistance
- Temporary and time-limited passcodes suit guests and short stays
Cons
- Lowest reviewed score in the group at 3.3 on only 4 ratings
- Requires the door frame to be wider than 2.87in before it will fit
- 4 AA batteries are not included
The distinguishing feature here is a visitor request function. The lock rings through the app like a doorbell, and the person at the door gets admitted once you let them in from your phone. For a rental or a home office, that is a genuinely useful workflow that no other lock in this group offers in the same form.
Temporary passcodes with time limits are also built in, which is the other half of what a short-term rental host needs.
Access methods number five: app, fingerprint, 16-digit virtual password, IC card and remote. Capacity is 100 users, 100 fingerprints, 100 cards and 10 remotes at 3 fingerprints each. The body is high-load stainless steel with corrosion resistance, and it weighs 1.47 kg.
Both a main and a sub lock are included, which covers double-sided framed sliding installations where you need to secure two panels. Auto-lock on closing, a constant-open mode and power bank emergency input round out the feature set, and the same unit is also sold under model LG2375.
The rating is not enough to trust
With 4 ratings and a 3.3 average, the one-star share of 24% carries almost no statistical weight. The listing summary in our data is blunt about it: too few reviews to draw firm conclusions, and a star spread wide enough to suggest an unproven product rather than a bad one.
Treat the features as real and the reliability as unproven. If you are furnishing a rental, buy one, install it, and test the app pairing before you hand a key to a guest.
The frame width check is mandatory
The panel is 7.28in on the long side and 2.87in wide, and the door frame must be wider than 2.87in before the lock will fit at all. That is a wide frame by slider standards, which rules out many aluminum and narrow vinyl doors.
Measure the frame first. If it is comfortably wider than 2.87in and you want doorbell-style remote admission, this is the only pick here that does it.
9. JNZCH Sliding Door Smart Lock – Best App Feature Set
Sliding Door Smart Lock, Sliding Glass Door Lock with Fingerprint
Tuya app with entry log
30-55mm fit window
IP65, -13F to 131F
4 AA, up to 6 months
Pros
- Deepest app feature set here with entry logs
- one-time and unlimited-use passcodes
- Peek-proof PIN adds random digits around your real code
- Cutting template and a trimmable spindle are included to ease fitment
- IP65 sealed across a -13F to 131F range
Cons
- Lowest rating in the roundup at 2.8 with 37% of reviews at 1 star
- Narrowest fit window at only 30-55mm door thickness
- Wi-Fi pairing works on the 2.4 GHz band only
- Listing has a generic title with no brand history
On paper this is the most capable app in the roundup. The Tuya app handles remote unlock after a doorbell ring, one-time 5-minute passwords, unlimited-use passwords, access management, an entry log and low battery alerts. Few door locks of any kind give you that combination at this level.
You also get a peek-proof PIN, where the keypad accepts random digits before or after your real code so nobody can read your entry from over your shoulder. The fingerprint sensor gives clear green and red feedback, and the lock auto-relocks after each use.
The build support is unusually thoughtful for this class. A cutting template and square shafts are included, and the shaft measures 3-5/32in and can be trimmed to your stile, which removes a frequent cause of install failure on a slider.
Connectivity is Wi-Fi on the 2.4 GHz band, which means no separate hub but a real setup gotcha. Unlock paths are fingerprint, IC card, PIN, Tuya app and mechanical key, and emergency power comes through a USB-C power bank input when the 4 AA cells run out.
Why 2.8 is the honest score
This has the biggest review base in the roundup at 48 ratings and the lowest average, with 37% one-star reviews. That combination is informative rather than damning: people bought it expecting the app, and the app and the fit did not deliver consistently.
Three causes show up repeatedly. Installation is described as difficult, the 30-55mm thickness window is the narrowest of any pick here, and 2.4 GHz-only pairing trips up a lot of routers. Measure your door and check your Wi-Fi band before ordering, and the score improves a lot.
Who should buy it anyway
Buy it if you want the app and you can confirm the fit. Doorbell-triggered remote unlock plus a full entry log is genuinely more than most competing locks offer, and no other unit here pairs that with a peek-proof PIN and an included cutting template.
Skip it if your door is outside 30-55mm thick, if you have a 5 GHz-only mesh network, or if you want a product with an established brand behind support. The generic listing title is a fair signal of what happens when something goes wrong.
10. Swokely Slim Lock with Camera – Best with a Built-In Camera
Swokely Slim Smart Lock for Sliding Glass Door, Waterproof Keyless Smart Mortise Lock with Camera, WiFi Keypad Aluminum Fingerprint Door Lock with Handle – 5 Unlocking Methods for 40-120mm Door
Camera in the mortise body
304 stainless steel
Fits 40-120mm doors
4 AAA, up to 6 months
Pros
- 304 stainless steel body
- a step up in material from the zinc and aluminum rivals
- Camera-equipped mortise body is unique in this roundup
- Waterproof design with voice guidance and an alarm system
- 40mm slim panel fits narrow aluminum frames
Cons
- Weak review evidence at only 5 ratings with a 42% one-star share
- Requires a 3585 lock body and 40mm minimum thickness rules out very slim sliders
- Costs more than the stainless rivals with the camera the only standout feature
Only one lock in this roundup puts a camera inside the mortise body, and if you want to see who is at your patio door without installing a separate doorbell camera, this is the pick. The five unlock methods cover fingerprint, card, password, app and key.
Material is the second argument for it. The body is 304 stainless steel with a waterproof design, which puts it ahead of the zinc and aluminum units in the group on both corrosion resistance and perceived quality.
The semiconductor fingerprint sensor is designed to reject duplicate fingerprints of the same finger, which reduces the false acceptance problem on cheaper sensors. Voice guidance and a low battery reminder are both built in, along with an intelligent alarm system.
Fit and the 3585 lock body
The panel is a slim 40mm wide, which suits narrow aluminum frames, and the door thickness range runs from 40mm to 120mm. That lower bound of 40mm is the real constraint: it excludes genuinely thin sliders, and you will need a 3585 lock body, which is a different part from the 2085 and 2885 bodies used elsewhere in this roundup.
Check the existing latch before ordering. If your door uses a 2085 or 2885, this is the wrong body and the wrong product.
How to read a 3.3 on five reviews
With 5 ratings the score is noise, but the distribution is worth noting: 58% five-star against 42% one-star is polarised, not mediocre. That usually means the unit is either a good fit or an immediate mismatch, with little middle ground.
Power is 4 AAA for up to six months. The silver finish suits a modern aluminum frame, and the package includes front and rear panels, lock body, cylinder, pins, two cards, two keys and a screw bag.
11. MSR605 Glass Door Lock with Tuya App – Best for Shared Passwords
Smart Glass Door Lock, 2026 New Keyless Entry Door Lock, Biometric Fingerprint Glass Door Locks, Electronic Keypad Biometric Lock with App Control, Sliding Door Smart Lock for Office, Home, Store
No-drill mount for 10-12mm glass
Tuya app with shared eKey
Unlocking history and silent mode
4 AAA, not included
Pros
- Full Tuya app control with unlocking records and temporary codes
- No-drill clamping mount for 10-12mm glass doors
- 360 degree fingerprint reader with an anti-peep keypad
Cons
- Only a single review on file so the 5.0 rating carries almost no weight
- Requires 4 AAA alkaline batteries that are not included
- Clamp fit is limited to 10-12mm glass
The 5.0 average on this listing comes from one review, so read it as a placeholder rather than evidence. What is worth looking at is the feature set, and the shared eKey function is the reason this lock is on the list at all.
In the Tuya app you can share access with someone, create temporary codes, view unlocking records, and switch the lock into silent mode so it does not beep when someone in the house uses it. For a shared house, a home office or a small studio, that combination of sharing plus history is more useful than a higher star rating would be.
Five access methods are supported: a 360-degree fingerprint reader, an anti-peep keypad code, Tuya app control, eKey or code sharing, and a mechanical key. The no-drill mount clamps to glass doors 10-12mm thick, so the fitting window is narrow.
What to verify before relying on it
With one review and no customer photos, there is no long-term data on battery drain, weather tolerance or app reliability. The #174 rank in security and surveillance biometrics suggests an early listing with early momentum, which is encouraging and also means the long-term record does not exist yet.
Two practical notes. It needs 4 AAA alkaline batteries, which are not included, and the 360-degree sensor and anti-peep keypad share the same glass face as the no-drill mount, so the glass must be a comfortable grip height for everyone who uses it.
Where a shared-eKey lock earns its place
If your household already runs the Tuya ecosystem, this lock slots into an app you have rather than asking you to learn a second one. Shared temporary codes remove the need to hand out keys, and the unlocking history tells you who came through the door and when.
Treat it as an untested but well-specified option. Buy it for an interior glass door first, and only promote it to an exterior entry once you have lived with the app for a few months.
12. Generic Frameless Remote Glass Lock – Best for Sliding or Swing Glass Doors
Frameless Remote Control Digital Sliding Swing Door Smart Lock for Glass Door
Sliding and swing glass doors
Adjustable glass thickness fit
Main plus secondary lock
Battery powered with remote
Pros
- Works on both sliding and swing frameless glass doors which is unusual in this category
- Adjustable fitting for varying glass thickness
- Main and secondary locks both included in the box
- Remote and smartphone control
Cons
- Listed as a Generic listing with no consumer brand identity
- Only 3 ratings so there is effectively no review evidence
- Very low sales rank suggests limited traction
Most frameless glass locks on this list are explicitly for swing or push-pull doors. This one is described as working with both sliding and swing motion, which makes it the only unit here that covers a frameless sliding glass door without an existing mortise.
That flexibility comes with adjustable fitting for varying glass thickness, and the box contains a main lock, a secondary lock, two ID cards, a screw package and a metal plate. Having both lock bodies means you can secure a double glass door without buying a second unit.
Control is via a dedicated remote or your phone over Bluetooth, with smart home system integration listed for added convenience. It is battery powered, and the compact 7.5 x 3.1 x 2.8 inch body is among the least bulky in the roundup.
An honest word about the brand
This is a Generic listing with a manufacturer name of Guangzhou Double Hercules Trading and no consumer brand. The 3.9 average sits on 3 ratings with a 36% two-star share, which means there is effectively no review evidence at all, and the very low sales rank confirms limited market traction.
The bullet points are also written as category copy rather than tested specifications. Verify the fit and the functions yourself before you depend on them, and keep the mechanical backup in mind.
When it is the right pick anyway
Choose this lock if you have a frameless glass door that both slides and swings, if you want a compact body that will not dominate the glass, and if you are comfortable with a product that has no brand behind it. The adjustable fitting is the feature that makes it worth the risk on a door where the alternatives do not fit at all.
For a primary exterior entry we would steer you toward a mortise lock with a documented review base instead. This one earns its place on secondary and interior glass doors.
How to Measure Your Sliding Door Before You Buy
Five measurements decide whether a lock fits, and every one of them takes under a minute. Get them written down before you browse, because the product pages rarely list a door-type compatibility chart you can rely on.
1. Door thickness. Measure the sliding panel edge to edge at the latch end with calipers or a tape. Mortise slider locks in this roundup cover 22-110mm or 22-120mm, while clamp-on glass locks accept only 10-12mm of glass. A door outside both ranges rules out that lock.
2. Frame or stile width. Measure the vertical frame member you will screw to. You need roughly 40mm for a slim lock body, 45mm for most mortise sets, 66mm for the NGTeco clamp-on unit, and more than 2.87in for the LG75TY. This single number eliminates more candidates than any other.
3. Existing lock body. Look at the interior edge plate. A 2085 body is a single hook, 2885 is a double hook, and 3585 is a different pattern again. A lock designed for one body will not drive another, and a mismatched mortise is the most common cause of a fit that looks right and fails anyway.
4. Gap and track clearance. Clamp-on glass locks specify a two-panel gap, commonly 0.16-0.59in, and a hook latch needs room to travel into the track. Measure the opening with the door fully closed.
5. Door direction and handle position. Confirm the slider opens with a reversible handle on the correct side, and check the spacing from the door edge to the existing pull. This is where install-day frustration comes from, and it is free to check in advance.
Which Access Method Fits Your Household
Every lock here supports several methods at once, so the question is which one you will actually use daily and which one is your fallback when the battery dies. Five options appear across this roundup.
Fingerprint. The fastest method in daily use and the hardest to duplicate, with capacity ranging from 100 prints on the Perfiware units to 300 profiles on the Eseesmart. It is the least useful with wet, gloved or very dirty fingers, which is why pairing it with a PIN is wise on an exterior door.
Numeric keypad. The most universal method, requiring no app and no phone. Look for the virtual or anti-peep variant, where the keypad accepts extra digits around your real code so a watcher learns nothing. Every lock in this roundup includes some form of it.
RFID or IC card. Fast and nearly indestructible, and the easiest method for a household with young children or for a business handing out cards. Its weakness is that a card is a physical item that gets lost, so treat it as one method among several rather than the only one.
App unlock. The reason most people want a smart lock at all, because you can admit a guest from the sofa or the office. It requires Wi-Fi, either built into the lock or through a gateway, and it is the biggest quality-of-life difference between the picks here.
Mechanical key. The emergency method, and the one most people forget. Confirm every lock you consider has a real key cylinder or backup key before you buy, and test it with the batteries removed.
Smart Home Ecosystem: Wi-Fi, Bluetooth and Tuya
Connectivity decides whether a smart lock is genuinely smart or a very expensive keypad. Three approaches appear here, and the choice is simple to make once you know which app you are willing to live with.
Bluetooth only. The Eseesmart works this way. Unlock from the app when your phone is in range, which is genuinely useful for a door at the end of a hallway, and remote access from elsewhere needs a gateway. Fine for most homes, insufficient for a rental host.
Built-in Wi-Fi. The Anweller, eLinkSmart, JNZCH, Swokely and MSR605 connect to an app directly with no separate hub, and two of them also issue temporary and scheduled codes. Check your router band first, because the JNZCH pairs on 2.4 GHz only and that trips up a lot of modern mesh networks.
Tuya versus branded apps. Most unbranded locks here run on Tuya, which is well-supported and has no subscription. The Yale runs its own app, which is the safer long-term bet if vendor longevity worries you, and it works with Alexa, Google Assistant and Siri. Forum discussion about smart locks frequently raises the fear of buying hardware whose app is later abandoned, and that is a fair reason to favour an established brand where the price gap is small.
None of the locks in this roundup advertise Z-Wave, Zigbee or Matter. If your home hub runs on one of those protocols, treat this category as outside your ecosystem and check compatibility before buying.
Installation: When a Screwdriver Is Enough and When You Need a Locksmith
Most installs here take between 10 and 30 minutes with a screwdriver, a tape measure and patience. The eLinkSmart advertises a 10-15 minute no-drill install, the NGTeco about 10 minutes, and the clamp-on glass locks use adhesive or clamps rather than a drill.
Two conditions send you to a locksmith, or at minimum a handy friend. If your door has multi-point lift-to-lock hardware, no lock on this list will work and a specialist motor is the only answer. If the existing mortise does not match the body the lock expects, swapping it means opening the door edge. A third case is branded hardware under warranty, where an improper fit can cost you the warranty.
Two practical warnings. On aluminum frames, drilling can split the extrusion and there is no second chance, so use the reversible clamp-on options if you cannot be certain. And on every install, test the lock state ten times with the door nearly closed, because a slider that unlocks correctly but fails to throw its hook will leave you quietly unlocked.
Cold weather on an exterior slider shortens battery life, so check the low-battery warning before the first freeze rather than after it.
Security: Pair a Smart Slider Lock With a Bar
A smart lock on a sliding door improves convenience far more than it improves security. A slider is a glass-adjacent entry, and the weak point is usually the door being lifted out of its track or the meeting stile being pried, not the latch, so no keypad changes that geometry.
For most homes the sensible combination is a smart slider lock for daily convenience plus a door security bar for actual deterrence. A bar is a fraction of the cost of the lock, defeats the lift-and-pry attack outright, and is invisible from outside when not in use. If the outer layer of the entry is what concerns you, our picks for the best storm doors for front entrances cover that layer separately.
On the electronics side, the sensible habits are unglamorous. Use a separate passcode per person so you can revoke one without reissuing the lock, never use the factory default code, keep firmware updated, and enable two-factor authentication on the app account where it exists. These locks transmit over encrypted connections and most use rolling codes, so the realistic attack surface is a shared password rather than a radio replay.
For residents and landlords: if you rent, check your lease before drilling an aluminum frame, and prefer the no-drill clamp-on options. A reversible install is the difference between a lock you can take with you and a damaged door you have to explain.
Frequently Asked Questions
Can you put smart locks on sliding doors?
Yes, but only with a lock built for a horizontal latch rather than a deadbolt. A deadbolt throws its bolt 90 degrees into a strike plate, and a sliding door has no strike to receive it. Sliding door smart locks are surface-mounted units with a horizontal hook latch that drives into the track, or with a mortise body such as 2085 or 2885 cut into the door edge. Clamp-on models for frameless glass doors are a separate family again. Measure door thickness, frame width and the existing lock body before you buy.
What is the best electronic lock for a sliding door?
For a mortise-style patio slider, the Eseesmart sliding glass door lock is the strongest all-round choice in our testing, fitting 22-120mm door thickness with an IP65 rating and a reversible handle. For a wide framed door where remote unlock matters, the Anweller 2885 set has built-in Wi-Fi so no gateway is needed. For a narrow aluminum frame, the eLinkSmart slim lock has a 36mm lock body and includes adapter sets covering 22-110mm.
Which smart door lock has the best fingerprint sensor?
Among the locks we reviewed, the Eseesmart and the Perfiware LG2315 and LG2215 report the fastest and most accurate fingerprint scanning in owner reviews, with capacity for 100 to 300 stored prints. The Swokely adds a semiconductor sensor designed to reject duplicate prints of the same finger. On an exterior door, pair any fingerprint reader with a keypad code, since wet or gloved hands read poorly on every sensor in this roundup.
What are the downsides of smart door locks?
The main ones are fit, power and app dependence. A lock designed for a different mortise body or a thinner frame will not work at all, and returns in this category are dominated by that problem rather than by defects. Battery life ranges from about 6 to 12 months depending on the model and usage, and cold weather on an exterior slider shortens that. Bluetooth-only models cannot be unlocked remotely without a gateway, and every unit depends on a vendor app that could in principle be discontinued.
How hackable are smart door locks?
The realistic risk is a shared or guessed code rather than a radio attack, because these locks use encrypted connections and rolling or temporary codes. Practise basic hygiene: change the factory default code, give each person a separate code so you can revoke one without reissuing everything, use the virtual or anti-peep keypad mode that accepts extra digits around your real code, and enable two-factor authentication on the app account. Add a door security bar, since the physical entry point matters more than the electronics.
Do I need a locksmith to install a smart lock on a sliding door?
Usually not. Most locks in this roundup install in 10 to 30 minutes with a screwdriver, and the clamp-on glass models need no drilling at all. Call a specialist when your door has multi-point lift-to-lock hardware, because no off-the-shelf lock will fit it, or when the existing mortise body does not match what the lock expects and the door edge must be opened. Drilling an aluminum frame without certainty can split the extrusion permanently.
Which Sliding Door Smart Lock Should You Buy in 2026?
Pick the Eseesmart sliding glass door lock if you have a mortise-style patio slider and want one of the widest thickness ranges with weather sealing and a reversible handle. Pick the Anweller 2885 set if remote unlock matters and you would rather not add a gateway, and it carries the largest review base of any lock here. Pick the Yale Assure Lock if your slider is an Andersen A-Series or E-Series patio door and brand-backed fit justifies the premium.
Pick the eLinkSmart slim lock for a narrow 40mm aluminum frame, the NGTeco smart glass door lock for a no-drill interior or cabinet glass door, and the Perfiware LG75TY if you need visitor doorbell requests and timed codes for a rental. Whatever you choose, measure the frame width and the existing lock body first, because fit decides more outcomes in this category than any feature list.
The best smart locks for sliding doors in 2026 are not a premium category, and the ratings reflect that. What they deliver is a working fingerprint reader, a keypad, temporary codes and an app, on hardware that finally fits a door that most smart locks were never designed for. Measure twice, and check the latch actually throws before you rely on auto-lock.
