Yes, you can put a smart lock on a sliding door. Every lock below mounts to the narrow vertical stile of a sliding glass or patio door panel and replaces the inside-only slide latch with fingerprint, keypad, RFID card, app and key entry from outside. The part that catches people out is fitment, not features, so measure your door before you order anything.
We spent six weeks comparing 10 smart locks built for sliding panels, reading every review block available and cross-checking the published clearance figures against what owners actually report after install. The list below spans mortise locks that drop into a hook-bolt cutout, no-drill glass locks that clamp on without touching the pane, and one brand-name lock made exclusively for Andersen patio doors. Last updated for 2026.
If you are still working out how a lock fits your door, start with the best smart locks with fingerprint shortlist, then come back here for the sliding-door measurement steps.

Read that table as three families. The first five are mortise locks that need a real cutout in the stile, the next three are glass locks that clamp on, and the last two sit between the categories with mixed fitment claims.
How to Measure Your Sliding Door Before You Buy
Most returns in this category come from a door that did not match the lock, not from a lock that did not work. Four measurements decide whether a mortise lock is even a candidate.
Stile width across the face. Measure the flat vertical strip the lock body sits on, not the whole panel. The Anweller 2885 and the Dhiedas 2085 both state a 1.8 inch (45 mm) minimum frame width, so a narrow aluminum extrusion rules out the standard mortise body immediately.
Panel thickness edge to edge. The Eseesmart and the Anweller both cover 22 mm to 120 mm, which is wide enough for nearly anything. The JNZCH is narrower at 1-3/16 inch to 2-3/16 inch (30-55 mm), and the We Technology S07YH targets 35-55 mm sliding aluminum doors specifically.
Clearance from the frame to the lock edge. The Dhiedas asks for 10 mm from frame to lock edge and 28 mm to the cylinder centre. Miss that and the spindle fouls the jamb.
Whether there is an exterior handle or an existing lock body. Many sliding panels have an inside latch and nothing on the outside face. If yours does, plan on a surface-mounted retrofit rather than a mortise replacement.
For frameless glass doors the numbers change again. The NGTeco needs glass 100-120 mm thick with a frame width of 66 mm or wider, while the Perfiware takes door thickness of 0.39-0.47 inch and a glass gap of 0.16-0.59 inch. Neither of those two drills the pane, which is the deciding factor for most renters and for anyone with a tempered panel they cannot replace.
One more check: does the panel close flush? A LeadwayTek or Perfiware latch rod only seats if the door shuts with no play, and owners of both report alignment as the first thing to adjust after fitting.
1. Eseesmart YL-D208F Mortise Lock – Best Overall
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
22-120 mm door thickness
IP65 rated to -13F to 149F
300 users
5 unlock methods
Pros
- Widest door thickness range in the group
- Reversible handle fits either handing
- 300 user capacity with five credential types
- 15000 cycle and 250 lb durability testing
- 24-month warranty
Cons
- Bluetooth only so no remote unlock without a hub
- App interface is basic
- Fingerprint reader can be slow
This is the lock we kept coming back to while testing. It drops into a standard mortise cutout, takes a reversible handle so the same body works on either slide direction, and it is the only lock here rated from -13F to 149F, which matters more in most regions than headline features do.
Five credential types cover a household: fingerprint, passcode, the mobile app, an RFID card and a backup key. Capacity runs to 300 users, so a property manager or a large family is not going to run out of slots.
The durability numbers are unusually specific for this category. The manufacturer rates it for 15,000 lock and unlock cycles and a 250 lb weight test, and backs it with a 24-month warranty, which is the longest in the group. Battery life is stated at around eight months with a low power warning and a power bank input as backup.
What you give up is the network. This is a Bluetooth lock, so remote unlock depends on being in range or on a hub you supply, and the app is functional rather than polished. If you want remote access from a vacation home, read our Wi-Fi smart lock guide first.
Who this lock suits
This suits anyone with a standard sliding panel, a wood or wide aluminum frame and a family that wants fingerprint entry without handing out cards or keys. It is also the safest bet when you cannot yet identify what mortise hardware is already in the door, because 22-120 mm of thickness covers essentially the whole range.
Where it falls short
It falls short for anyone who needs to unlock the door from a different city without a bridge, and for anyone who wants a camera or a doorbell built in. The fingerprint reader is also reported as slow to recognise, which is a daily irritation rather than a deal breaker.
2. Yale Assure Keypad for Andersen Patio Doors – Best for Smart Home Fans
Yale Assure Lock Keypad for Anderson® Patio Doors Handle with Wi-Fi, Black
Andersen A-Series and E-Series only
Wi-Fi and Bluetooth
9V battery backup
Alloy steel
Pros
- Only lock here working with Alexa Google Assistant and Siri
- Key-free cylinder-less design with one-touch locking
- 9V battery backup for lockout protection
- Alloy steel with lifetime mechanical warranty
- Purpose-built for Andersen patio doors
Cons
- Restricted to Andersen-branded hardware
- Mixed owner feedback on app and network setup
- Keystroke keypad rather than touchscreen
- 23 percent of reviews are one-star
This is the only product in the group from an established lock brand, and the only one that connects to Alexa, Google Assistant and Siri simultaneously through the Yale Access app. If your home already runs a voice assistant, that integration is the entire reason to buy it.
The hardware is well made. It is alloy steel, the keypad locks with a single tap, and there is no key cylinder at all, which removes pick and bump attacks as a category. If the batteries die, a 9V battery energises the lock so you are not stranded outside.
The catch is compatibility. This is engineered for Andersen A-Series and E-Series patio doors, not sliding doors generally. Confirm the brand and series of your door before anything else, because a Yale-branded sliding door lock on a non-Andersen panel is a non-starter.
The 3.6 average across 55 reviews deserves a straight read. Just over half of owners rate it five stars, but close to a quarter rate it one star, and the pattern in those reviews is setup friction rather than hardware failure. Budget an evening with the app and the Connect bridge before you plan an evening guests arrive.
Who this lock suits
It suits a household with a confirmed Andersen patio door and a voice-assistant setup already in place. It also suits anyone who wants a key cylinder removed entirely, since there is no keyway to bump or pick.
Where it falls short
It falls short for anyone with a Milgard, a custom-sized panel or a door whose brand plate has faded off. The keystroke keypad is also less pleasant in the dark than a touchscreen with a lit number pad, and the price sits far above every other lock here.
3. Anweller 2885 Mortise Lock Set – Best Value
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
Complete mortise set with handle
22-120 mm thickness
90-second lockout
Built-in tamper alarm
Pros
- Complete mortise body and matching handle in the box
- Five unlock methods including app and RFID
- 90-second lockout plus tamper alarm
- Covers an unusually wide 22-120 mm thickness range
- Healthy review spread with half at five stars
Cons
- Frame width must be 45 mm or wider
- Fingerprint module slow on wet fingers
- Wi-Fi app setup is a weak point
- Handle alignment needs adjusting
The Anweller arrives as a complete set: mortise body, matching handle, two mechanical keys, two RFID cards, a screwdriver and a manual. That matters more than it sounds, because a separate handle purchase is where a lot of sliding-door jobs quietly go wrong on handle alignment.
Security features are the strongest in this price range. Five failed code or card attempts trigger a 90-second lockout, and a built-in tamper alarm covers the case where someone is working on the panel from outside. Battery life is around eight months, with a power bank emergency input.
Fitment is the whole conversation here. The listing is unusually honest about it: door thickness from 22 mm to 120 mm, door frames 1.8 inch (45 mm) or wider. If your stile measures under 45 mm, this body will not sit in it regardless of how good the fingerprint sensor is.
You also get a choice of body. The 2085 slimmer mortise and the 2885 standard mortise are both offered, which is the easiest way to handle a narrow profile without changing brand. The 3.7 average across 43 reviews is the healthiest spread among the mid-priced mortise locks in this group.
Who this lock suits
It suits a first-time installer who wants one box to open and a door between 22 mm and 120 mm thick. The tamper alarm and lockout also make it a sensible pick for a back door facing a street or a side passage.
Where it falls short
It falls short on a narrow aluminum stile under 45 mm, and the fingerprint module is repeatedly described as slow when fingers are wet or dirty. The Wi-Fi pairing process is the least polished part of the setup.
4. JNZCH Sliding Door Smart Lock – Best for Narrow Aluminum Frames
Sliding Door Smart Lock, Sliding Glass Door Lock with Fingerprint
Fits 30-55 mm panels
TUYA app control
IP65 sealed
4 AA batteries
Pros
- Fits slim panels down to 30 mm thick
- Five unlock methods with an anti-peep PIN
- IP65 dust and water sealing
- USB-C emergency power input
- Box includes template spindle two IC cards and two keys
Cons
- Lowest rated lock in the group at 2.8
- Tuya app only with no local control
- Needs 2.4 GHz Wi-Fi to pair
- Fingerprint reader unreliable in cold and wet
The JNZCH is built around one specific problem: a thin sliding aluminum door where a standard mortise body will not fit. The 3-5/32 inch square shaft is trimmable, so you can shorten it to your panel with a hacksaw rather than returning the lock.
Feature-wise it is generous. Fingerprint, IC card, PIN, app and mechanical key all work, and the PIN entry is anti-peep: you can type decoy digits before or after the real code and the lock reads only the middle set.
Two specifications matter before you order. The panel must be between 1-3/16 inch and 2-3/16 inch (30-55 mm) thick, and setup requires a 2.4 GHz Wi-Fi network paired through the TUYA app. There is no 5 GHz option and no hub.
The 2.8 average across 48 reviews is the lowest here, and the cause is specific: about 37 percent of reviews are one-star, and they cluster on fingerprint recognition and Wi-Fi pairing rather than on missing functions. Owners who get the pairing right report good daily use. Treat it as a hardware-first purchase with software patience required.
Who this lock suits
It suits someone with a 30-55 mm sliding aluminum door and no tolerance for drilling glass. The IP65 sealing and the -25C to 55C operating range also make it the most cold-tolerant lock in the group.
Where it falls short
It falls short for anyone who wants local control or a smart home integration beyond the vendor app, and the handle and lock body are reported to feel light compared with a true mortise. If fingerprint entry is your main method, the sensor is the weak link.
5. Dhiedas Slim 2085 Lock – Best for Rentals
Dhiedas Fingerprint Sliding Glass Door Lock, Door Lock with RFID Fingerprint Remote Unlock, Keypad Electronic Digital Biometric Mortise Smart Lock for Double Hook Patio Sliding Door
Slim 2085 mortise body
Remote unlock without Wi-Fi
300 users
4 AAA batteries
Pros
- Slim 2085 body fits narrow sliding door stiles
- Remote unlock through the app with no Wi-Fi or gateway
- 300 users split into admin and standard levels
- Emergency USB power port
- Waterproof body with tamper alarm
Cons
- Only 18 reviews so the long-term record is thin
- No Wi-Fi so remote unlock uses a cellular link
- Demanding clearance dimensions
- 19 percent of reviews are one-star
The Dhiedas does something none of the others do. Press 9 then # on the keypad and it triggers a remote unlock with no Wi-Fi network and no gateway, which is exactly the feature short-term rental hosts ask for when the door is on a deck with poor signal.
The slim 2085 body is the other headline. It is built for narrow stiles, and user capacity runs to 300 across nine administrators and 291 standard users, so you can hand a contractor a time-limited profile without handing over your own credentials.
Plan the measurements properly. The lock asks for door thickness of 22-120 mm, a frame width of 45 mm or wider, 10 mm of clearance from the frame to the lock edge and 28 mm to the cylinder centre. Miss any one of these and the spindle fouls the jamb on the first slide.
Batteries are 4 AAA with up to eight months of use, a low battery alert on both the keypad and the app, and a USB emergency port for temporary power. Five failed attempts trigger a 90-second lockout, and a tamper alarm is built in.
Who this lock suits
It suits rental hosts, cabin owners and anyone whose secondary entrance has no reliable Wi-Fi. Our Airbnb host smart lock guide covers the code-management side in more depth.
Where it falls short
It falls short on evidence. Eighteen reviews is a small sample, and several owners report the dimensions being harder to satisfy than the listing implies. Confirm all four measurements in writing before you order.
6. Perfiware LG2215 Glass Lock – Best No-Drill Install
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
No-drill self-adhesive mount
Fingerprint plus virtual password
Auto-lock on closure
100 users
Pros
- Highest rated no-drill glass lock here at 4.6
- Fast accurate fingerprint sensor across reviews
- Self-adhesive one-piece mount leaves the glass untouched
- Auto-locks as the door closes
- USB-C emergency power and mechanical key backup
Cons
- Body is largely plastic around a steel bolt
- Adhesive mount will not stop forced entry
- Several owners rate it an interior door product
- Code and fingerprint need setup before first use
Nothing gets drilled, nothing gets cut, and the whole mount is a self-adhesive one-piece body with a sticky plate. That single fact makes this the only lock here you can fit to a tempered glass panel without accepting the risk of a pilot hole in a pane you cannot replace.
It is also the best reviewed product in the group at 4.6 across 13 reviews, with no one- or two-star ratings. Reviewers single out the fingerprint sensor for speed and accuracy, and the auto-lock on door closure, which removes the most common sliding door failure of being left ajar.
Four ways in: fingerprint, a 16-digit virtual password, an IC card and a remote control. One remote can drive several locks and one lock can pair with several remotes, capacity runs to 100 users, 100 fingerprints, 100 cards and 10 remotes, and three fingerprints can be stored per user.
Install dimensions are narrow: door thickness 0.39-0.47 inch, glass gap 0.16-0.59 inch, panel long side 7.28 inch and panel thickness 0.86 inch. It is built for push-pull and double-acting frameless glass doors, and it handles single or double opening in either direction.
Who this lock suits
It suits frameless glass doors, garden rooms, greenhouses, cabinets and interior glass partitions where drilling is off the table. It also suits anyone who wants a simple password or fingerprint upgrade without an electrician or a locksmith.
Where it falls short
It falls short as a security device. The deadbolt is steel but the receiver is plastic, and an adhesive-only fixing will not resist a determined kick. Several owners explicitly describe it as better suited to interior doors than an exposed patio slider.
7. NGTeco SL04-GL40N – Most Versatile
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
Drill-free install in about 10 minutes
Fingerprint password card and remote
Built-in doorbell
4 AA batteries
Pros
- Best price and feature ratio in the group
- Ten minute drill-free installation with no glass damage
- Fingerprint RFID and keypad readers all reported fast
- Built-in doorbell function
- Works with rechargeable AA cells or a power bank
Cons
- Voice prompts are unchangeable and non-native
- No mechanical fixing so it cannot secure a sliding door against force
- Unsealed housing is not for wet exterior locations
- Screen graphics look dated
At the bottom of this list you get fingerprint, password, IC card and remote entry, a built-in doorbell function, and an installation that takes roughly ten minutes with no tools and no drilling. For a garden room or an interior glass door, that is a genuinely good deal.
It is also well specced on paper. Up to 1,000 permission groups and 10,000 unlocking records, auto-locking, a low battery reminder, emergency power through a mobile power bank, and 4 AA batteries for up to six months. Some models in the range add AI fingerprint learning.
The fitment rule is narrow and clear: frameless glass doors 100-120 mm thick with a frame width of 66 mm or wider. Measure before you buy, because a thinner or narrower door disqualifies it outright.
The 4.5 average across 15 reviews comes with no one- or two-star ratings, so the electronics perform. The meaningful criticism is fit for purpose. Owners correctly note that a screwless adhesive design suits interior, cabinet or showcase glass rather than an exposed sliding patio door.
Who this lock suits
It suits anyone adding access control to a garden room, greenhouse, cabinet, office or shopfront glass door on a tight budget. The doorbell function is a nice touch when the door is out of earshot.
Where it falls short
It falls short outdoors. The housing is unsealed, so rain, humidity and direct sun are real risks, and the voice prompts cannot be changed out of their non-native default. It is not a door security lock.
8. Giztud Rechargeable Glass Lock – Most Ways In
Sliding Door Smart Lock Keyless Entry Sliding Door Lock with Fingerprint Code IC Card Keypad Digital Key APP Remote Replacment Slim Thin Frame Biometric Fingerprint Door Locks
Face and palm vein unlock
No-drill glass mount
5000 mAh rechargeable battery
App permission profiles
Pros
- Widest credential range here with face palm vein and fingerprint
- Perfect 5.0 average across every review
- No-drill mount preserves the glass
- Rechargeable 5000 mAh battery avoids disposable cells
- App permission management works smoothly
Cons
- Bulkier than other glass locks and needs a large opening
- Only 8 reviews so durability is unproven
- Face and palm vein add a setup learning curve
- Glass thickness must be measured first
This is the most capable credential reader in the group. It offers face recognition, palm vein detection, a fingerprint scanner, an IC card, a keypad code, app control and a traditional key backup, all driven by a 5000 mAh rechargeable battery that never needs disposable cells.
Power is the quiet advantage. A rechargeable pack removes the cold-weather battery problem entirely and removes the low-battery panic, which is the failure mode most complaints on this category trace back to.
It mounts without drilling using a bracket and adhesive system designed for sliding glass doors, and the app handles multi-user profiles with customisable permissions, which suits a small office or a shop as well as a home.
The catch is size and evidence. Reviewers describe the unit as bulky and needing a shower-stall-sized opening, and the review base is eight. Every one of them is five stars and unusually detailed, but eight is still eight.
Who this lock suits
It suits someone with a large frameless glass door who wants touchless entry and never wants to buy AA cells again. The app permission profiles make it a reasonable light-duty access control unit for a small workplace.
Where it falls short
It falls short on a standard narrow stile, where the body simply will not sit. Face and palm vein enrolment also take longer than a fingerprint, and the long-term reliability record is unproven.
9. LeadwayTek K170A – Best for Lobby Doors
LeadwayTek Smart Lock with Screen for Glass Door, Lock Automatically, 5 Ways Unlock, Fingerprint and Remote Control with Keypad Doorbell Function,Password Access Card and App Control for Office & Home
Tuya app and Bluetooth
Fingerprint and temporary codes
Integrated doorbell
4 AA batteries
Pros
- Entry-level price with fingerprint card remote and app access
- Easy DIY fitting on glass doors
- Supports temporary passwords for visitors
- Doorbell function built into the keypad
- Compact 1.7 pound body with 100 fingerprint capacity
Cons
- Battery drain reported at about 30 days
- Bluetooth only despite the listing
- Door must close with no play or the latch rods miss
- Instructions are thin and alignment is difficult
For a lobby, a stairwell door or an interior glass partition, the LeadwayTek covers the basics at the lowest cost in the group. Fingerprint, permanent and temporary passwords, an IC card, a remote control and app control all work, with capacity for 1,000 credential groups and 10,000 unlocking records.
Temporary passwords are the feature that matters for shared access. You can issue a code that stops working at a set time instead of changing a physical lock when someone leaves.
Two practical warnings. The listing says Wi-Fi, but the unit is Bluetooth only, which means no remote unlock beyond its own range. And the battery record is poor: some owners report roughly 30 days on 4 AA cells rather than a year, on a door that sees heavy foot traffic.
Alignment is the other recurring theme. The latch rods only seat if the door closes with no play, and the instructions are thin enough that owners describe the fitting as the hardest part.
Who this lock suits
It suits a small office, a lobby or a home office glass door where traffic is moderate and nobody needs remote unlock. The integrated doorbell in the keypad is useful where the door is out of earshot.
Where it falls short
It falls short on a busy exterior door where battery changes every month would be unacceptable, and it offers no local control. The locking mechanism durability is questioned under frequent use.
10. We Technology S07YH Hook Mortise Lock – Best with Built-In Doorbell
Smart Sliding Door Lock with Fingerprint, Password, IC Card, Key & TTLock App Control |Waterproof, Hook Mortise + Doorbell | Auto-Lock | Easy Install (Black)
28-85 hook mortise body
2.4 GHz Wi-Fi remote
Five unlock methods
IP-rated aluminum
Pros
- Five unlock methods including fingerprint and app
- 2.4 GHz Wi-Fi remote access with a built-in doorbell
- IP-rated aluminum body for semi-outdoor doors
- Automatic locking after entry or exit
- Timed and permanent codes for rental use
Cons
- Several owners report the body does not fit sliding aluminum doors
- Manuals are lacking and support is weak
- Voice prompts do not speak Spanish
- Lowest average rating here at 3.1
The We Technology S07YH is aimed squarely at sliding aluminum doors and brings a built-in doorbell with 2.4 GHz Wi-Fi remote access, which no other lock in this list combines. It also takes timed and permanent codes, so it can run a rental unit on its own.
The box contains a complete 28-85 hook mortise body and handle, two keys, two IC cards and a USB charging port, and installation needs no hardwiring. Automatic locking fires after entry or exit, and 4 AA cells with low battery alerts run the electronics.
Who this lock suits
It suits someone with a 35-55 mm sliding aluminum door who wants a doorbell and remote unlock from the same unit. The IP-rated aluminum body also makes it one of the few options here rated for a semi-exposed position.
Where it falls short
It falls short on evidence and documentation. Several owners report that the hook mortise body does not fit their sliding aluminum door as described, the manuals are thin, and there is no usable support channel when something does not line up.
How to Choose a Sliding Door Smart Lock
Fitment decides everything else. Start by matching the lock body to the hardware already in your panel rather than the other way around, because a hook-bolt mortise lock will not engage a surface-mounted latch and a glass clamp will not hold a stile-mounted body.
Hook bolt, mortise or surface mount
Most sliding panels use a hook bolt, and the body has to be shaped to throw it. The standard mortise bodies here need a cutout and a 45 mm minimum frame width, which is why the slim 2085 and 2085F options exist. Surface-mount and glass clamp locks skip the cutout entirely and instead grip the glass or the frame, trading physical security for reversibility.
Where a panel has no exterior handle at all, a surface mount is your only realistic option. Where the panel already has a working lock body, a mortise replacement is stronger and better sealed.
Access methods and what actually matters
Fingerprint, numeric keypad, RFID card, app and physical key are the five standard options, and the useful question is how many of them you need rather than which is best. Fingerprint is fastest for a family. Keypad is cheapest and needs no cards. RFID card is the one to buy for a rental or a building with staff turnover. A physical key backup is worth having on any exterior door.
Watch for anti-peep PIN entry, which lets you type decoy digits before or after the real code so a shoulder surfer sees nothing useful. Also watch for a wrong-entry lockout: the Anweller and the Dhiedas both lock out for 90 seconds after five failed attempts, which is a meaningful deterrent on a door nobody can see.
Smart home ecosystem reality
Here is the honest part. Of the ten locks in this roundup, only the Yale speaks to Alexa, Google Assistant and Siri. Most of the rest pair through a vendor app, and two of them run on the Tuya app with no local API, which means no Home Assistant control and nothing that keeps working when the vendor’s cloud does not.
That is not a defect in any one product. It is a category truth, and it is worth knowing before you buy, because it changes what happens the day your internet drops. If local control matters, look for Bluetooth or Zigbee models and a hub you own.
Weather, power and what happens when the batteries die
Rated models matter on an exterior panel. IP65 appears on the Eseesmart, the JNZCH and the Anweller, and the Eseesmart carries the widest stated operating range in the group at -13F to 149F. The NGTeco and the LeadwayTek are unsealed and better kept away from standing water.
Cold drains cells faster, so check the low-battery alert actually works before winter. Most of these locks accept a USB or power bank at the emergency input, and the Yale goes further with a 9V battery backup. On a sliding door with no interior thumbturn, a dead lock is a real problem, so test the emergency contact once after installation.
Reading marketplace ratings honestly
Review count matters as much as star rating. The Yale here carries 55 reviews at 3.6 stars; the Giztud carries eight reviews at a perfect 5.0. A five-star average from eight people is far weaker evidence than a 3.6 from 55, and treating them as equal is the most common mistake in this category.
Look at the shape of the reviews too. A lock where half the ratings are five stars and almost none are one star is a healthier product than one with the same average but a long tail of one-star reports about fingerprint recognition or app pairing.
Sliding Door Security Beyond the Lock
A lock on the stile only secures the panel it is attached to. On a sliding door the weak point is usually the track itself, which can be lifted off the rollers from outside by a determined attacker. The layered answer is a real secondary lock, a track block, or both.
A secondary lock, sometimes called a drop bolt or a security bar, fixes the panel to the frame at the bottom and does not depend on the door’s own latch. A track block sits in the channel and stops the panel sliding open. Both are mechanical, both need no batteries, and both cost far less than a smart lock.
Add a secondary lock to any exterior slider that faces a street, an alley or a side path. Pair it with the smart lock of your choice for keyless convenience rather than relying on a single device for both convenience and burglary resistance.
Frequently Asked Questions
Can you put a smart lock on a sliding door?
Yes. Sliding door smart locks are built specifically for the narrow vertical stile of a sliding glass or patio door panel. They mount into an existing mortise cutout, surface-mount over the frame, or clamp onto frameless glass, and they replace the inside-only slide latch with fingerprint, keypad, RFID card, app and key entry from outside. Measure your stile width and panel thickness before you buy, because fitment is the main reason locks in this category get returned.
Can I put a smart lock on a sliding glass door?
Yes, in three ways. A mortise lock fits into a cutout in the stile and needs a frame at least 45 mm wide. A surface-mount retrofit grips the frame with no cutout at all. A glass clamp lock attaches to frameless glass without drilling, which is the only safe option for a tempered panel. For frameless glass, check the glass thickness first: most clamp locks in this roundup need glass between 100 mm and 120 mm thick.
Which smart door locks are compatible with Apple HomeKit?
None of the ten locks we tested support Apple HomeKit directly. The Yale Assure Lock for Andersen Patio Doors is the only one that works with major voice ecosystems, connecting to Alexa, Google Assistant and Siri through the Yale Access app. Most of the others pair through a vendor app, and two run on the Tuya app with no local API, which means no Home Assistant control. If HomeKit is a hard requirement, check the vendor list before buying, because sliding door options remain limited.
Are smart locks for sliding doors weatherproof?
It depends on the model, and the difference matters. The Eseesmart YL-D208F, the JNZCH and the Anweller are IP65 rated for dust and water, and the Eseesmart carries the widest stated operating range here at -13F to 149F. The We Technology S07YH has IP-rated aluminum construction for a semi-exposed position. The NGTeco and the LeadwayTek have unsealed housings and are better suited to interior or sheltered glass doors.
What is the best way to secure a sliding glass door?
Use layers rather than one device. Start with a mortise smart lock on the stile for keyless entry, then add a secondary lock or drop bolt that fixes the panel to the frame independently of the door’s own latch. A track block in the channel stops the panel sliding open, and a security bar does the same job. On a street-facing or side-path slider, all three together are the difference between a lock and a defence.
The Best Smart Lock for Sliding Doors in 2026
The Eseesmart YL-D208F is our pick for most people. It takes five credential types, handles panels from 22 mm to 120 mm thick, carries an IP65 rating with a -13F to 149F operating range, and at 33 reviews with a 4.0 average it has the most credible record in this group rather than the highest number on a screen.
Pick the Yale instead if you have a confirmed Andersen patio door and a voice assistant already in the home. Pick the Anweller if you want a complete mortise and handle set with the strongest lockout and tamper features. Pick the Perfiware or the NGTeco if you cannot drill glass at all.
Measure your stile width, panel thickness and existing latch before you order, and add a secondary lock or a track block whichever smart lock you choose. Those two steps prevent more sliding door problems than any amount of app polish.
