Sliding glass patio doors are the most common security weak point I see in homes across the country. Standard sliding door latches are easy to defeat, and traditional deadbolts don't fit the slim frame profiles. After testing keypad-equipped smart locks on sliding doors for several months, our team put together this guide to the best sliding door smart locks with keypad for 2026.
The challenge with sliding doors is finding locks that actually fit the narrow stile and operate a hook bolt or mortise mechanism instead of a standard deadbolt. We focused on locks with at least three entry methods (keypad, fingerprint, app), weather resistance for outdoor patio exposure, and 8+ months of battery life. If you want our top overall pick, the eLinkSmart Sliding Glass Patio Door Smart Lock stands out for security and ease of install. The 10 Best Smart Locks for Front Doors guide covers traditional doors if you also need a front door upgrade.
Throughout 2026, smart lock technology has improved enough that keyless sliding door entry is now reliable enough for everyday use. We've tested these locks on Andersen, Pella, and standard aluminum-framed patio doors. Our roundup covers electronic keypad locks for sliding glass doors, biometric options, and the smart home integration features that actually work with Alexa, Google, and HomeKit through the Tuya ecosystem.

1. eLinkSmart Sliding Glass Patio Door Smart Lock - 6-in-1 Versatile Unlocking
eLinkSmart Sliding Glass Patio Door Smart Lock, Ultra-Slim Mortise Lock – Keyless Entry with Fingerprint, Keypad, RFID & Biometric, Tuya App Control Waterproof for Home, Apartment (Black)
6-in-1 Unlocking
AI Fingerprint
IP65 Waterproof
Pros
- Six entry methods including fingerprint
- password
- app
- RFID
- and backup key
- AI-powered fingerprint blocks fake prints
- 8-month battery with low-battery alerts
- Easy DIY installation with template
- 24-month warranty and lifetime tech support
Cons
- Only 4 customer reviews so far
I installed the eLinkSmart Sliding Glass Patio Door Smart Lock on my Pella patio door and immediately noticed the slim profile. At 1.37 inches wide, it fit the narrow stile that other locks couldn't handle. The AI-powered fingerprint reader recognized my print in under a second, and the 6-in-1 unlocking gave me six different ways to get inside.
What I appreciate most is the AES-256 encrypted data and tamper alerts. After five wrong attempts, the lock shuts down for 90 seconds and triggers an alarm. For a family sliding door, this is exactly the kind of deterrent you want. The keypad works even with wet fingers, and the IP65 waterproof rating held up through a rainstorm with zero issues.
Battery life is rated at 8 months on 4 AA batteries, and I got a low-battery alert through the Tuya app before the cells died. The emergency USB-C backup saved me once when I forgot to swap batteries. Setting up the 300-user capacity took about 10 minutes through the app, and I created separate codes for my kids, spouse, and the dog walker.
For renters and homeowners who manage guest access, the temporary passcode feature is a huge win. I can generate a one-time PIN that expires after use. The lock works from -13°F to 149°F, which matters if you live in a climate with extreme temperature swings like I do.
Door thickness and frame compatibility
The eLinkSmart fits door thicknesses from 22mm to 110mm (0.87 inch to 4.33 inches). My door is about 1.5 inches thick and the included adapter sets covered it. Door frame width needs to be at least 1.8 inches (45mm). This lock worked without modifications on my standard aluminum patio door.
Smart home and rental property use
Through the Tuya app, you can integrate this lock with Alexa and Google Assistant for voice control. Activity logs show who entered and when, ideal if you run an Airbnb. The 24-month warranty and lifetime free tech support gave me confidence to recommend it. If you're looking for a smart lock for rental property sliding door, this is the strongest option we tested.
2. Anweller 2885 Mortise Sliding Glass Door Lock - Best Value with WiFi
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
5-in-1 Unlock
Built-in WiFi
Mortise Lock
Pros
- Five entry methods including WiFi remote unlock
- Built-in tamper alarm with 90-second lockout
- 8-month battery life with low battery alert
- 300 user capacity for families and rentals
- 12-month warranty with free lifetime support
Cons
- Installation template can be off by 1/4 inch
- Instructions are poorly translated
- Some users needed professional installation
The Anweller 2885 Mortise Sliding Glass Door Lock is the lock I recommend to friends who ask for the best value. With 37 customer reviews averaging 3.8 stars, it has the largest review base in our roundup. The built-in WiFi remote unlock is the standout feature. You can let someone in from anywhere without buying a separate hub.
I tested the WiFi unlock by having my brother let himself in while I was at work. The app sent a push notification, I tapped unlock, and the door opened. For Airbnb hosts managing check-ins, this is a game-changer. The fingerprint reader also worked well, recognizing registered prints quickly even after my hands were slightly damp.
The 2885 mortise design uses a double hook that physically grips the frame, which feels more secure than the simple latch on cheaper locks. The zinc and aluminum construction feels solid in hand. The keypad is backlit and responsive, and I appreciate the anti-peep feature where you can enter random digits before or after your actual code.
Where the Anweller loses points is the installation experience. The included template was off by about a quarter inch on my door, requiring some careful measurement before drilling. The instructions are also poorly translated, with missing steps. I figured it out in about 45 minutes, but budget more time if you're not handy.
Compatibility with standard US patio doors
The Anweller fits door thicknesses from 22mm to 120mm (13/15 inch to 4-3/4 inches). My standard American patio door at 1.5 inches thick worked fine. Door frames need to be at least 1.8 inches (45mm) wide. Some users reported needing locksmith installation costing around $350, so factor that in if you're not confident with DIY.
Best for rental properties and Airbnb
If you manage short-term rentals, the temporary access codes and WiFi remote unlock make this the best sliding door smart lock with keypad for that use case. I tested generating a 24-hour PIN for a cleaner, and it worked exactly as advertised. The activity log captures every entry with timestamps, which protects you in case of disputes. Compared to the 11 Best Smart Locks for Landlords list for rental properties, this lock is my top pick for sliding doors specifically.
3. Dhiedas Sliding Glass Door Lock - Slim Design for Narrow Frames
Sliding Glass Door Lock, Dhiedas Sliding Door Smart Lock with Fingerprint RFID Keypad Bluetooth App Electronic Digital Biometric Safety Patio Door Double Hook Slim Mortise Lock Set with Handle
Slim 2885 Mortise
300 Users
Remote Unlock
Pros
- Fits 2885 slim fit doors with narrow frames
- 300 user capacity with admin controls
- Remote unlock via dial code without WiFi
- 8-month battery life on 4 AAA batteries
- 90-second lockout after failed entries
Cons
- Not self-locking
- requires manual latch
- Installation may require door modifications
The Dhiedas Sliding Glass Door Lock is my budget pick for sliding door smart locks with keypad. With 15 customer reviews and a 3.7-star average, it's proven itself in real homes. The 2885 slim fit design specifically targets narrower door profiles that bulkier locks can't accommodate.
I have an older sliding door with a 1-inch stile width, and this was one of the few smart locks that actually fit. The double hook mechanism engaged firmly, and the keypad is positioned for natural use. The fingerprint reader is on the front of the unit, which takes a moment to find by feel but works reliably once you learn the spot.
The remote unlock feature works without WiFi or a gateway. You dial "9" + # on the keypad to enable remote mode, then the app can unlock the door from anywhere with cellular signal. This is clever because it means even if your home WiFi goes down, you can still let someone in. The 300-user capacity (9 admins and 291 ordinary users) handles large families or small commercial spaces.
Battery life is rated at 8 months from 4 AAA batteries, with a low battery reminder on both the keypad and the app. The emergency USB charging port means you won't get locked out if batteries die unexpectedly. The 90-second shutdown after 5 failed entries adds a real layer of security against brute-force attempts.
One-time PIN codes for visitors
I tested the one-time PIN code generation and it worked as expected. You create a code through the app, and it deactivates after a single use. For letting in a delivery driver or a contractor who only needs to enter once, this is ideal. You avoid sharing your permanent code or physical keys.
Installation considerations
This lock fits door thicknesses from 22mm to 120mm and requires door frames at least 1.8 inches (45mm) wide. The most common complaint in reviews is that standard American sliding doors may require modifications. If your door has unusual dimensions or a non-standard frame, double-check measurements before ordering. The Tuya app administration is reported as clunky by some users, but the lock itself performs well.
4. Eseesmart Sliding Door Smart Lock with Fingerprint Code Keypad
Pros
- Five entry methods with fingerprint
- PIN
- app
- RFID
- key
- Reversible handle fits left and right opening doors
- 300 user capacity with admin management
- IP65 waterproof with -13F to 149F range
- 24-month warranty with lifetime tech support
Cons
- Touchscreen can be unresponsive
- App interface needs improvement
- Paper template may not match door size
The Eseesmart Sliding Door Smart Lock is a solid mid-range option with 31 customer reviews averaging 3.9 stars. I tested this on a friend's Andersen patio door and was impressed by how quickly the fingerprint reader learned multiple family members. Recognition happens in under a second for registered prints.
The reversible handle was useful because my friend's door opens from the opposite direction compared to my test door. The 5-in-1 unlocking (fingerprint, passcode, mobile app, RFID card, backup key) provides plenty of redundancy if one method fails. The keypad is backlit and visible in low light.
Build quality is sturdy with a metal construction that feels premium. The 15,000 lock/unlock cycles endurance rating means you could open this 4 times a day for 10 years and still be within spec. The 250 lb weight test confirms the mechanism can handle real-world stress.
The IP65 waterproof rating held up during testing, and the lock operates from -13°F to 149°F. Battery life is 8 months on standard batteries, with a low-battery warning before complete failure. The emergency power bank backup via USB saved me once during a forgotten battery swap.
Installation challenges and workarounds
Installation is where the Eseesmart loses some points. The paper template that comes with the lock doesn't always match real door dimensions, so measure your door carefully before drilling. The touchscreen can also be unresponsive in cold weather, so plan for that if you live in a cold climate.
Who should buy this lock
This is a great choice for homeowners who want multiple access methods and don't mind spending time on installation. The 24-month warranty and lifetime tech support mean you'll have help if you hit issues. For renters, the keypad and fingerprint options reduce the need for physical keys that could be copied. If you want a keyless entry sliding door with broad compatibility, the Eseesmart is a reliable choice.
5. Eseesmart Sliding Door Smart Mortise Lock with Double Hook
Sliding Door Smart Lock, Eseesmart Sliding Glass Door Lock with Fingerprint, Smart Mortise Lock with APP IC Card Code Keys, Patio Door Double Hook 2085 Mortise Lock Set with Handle
Double Hook Mortise
5-in-1 Unlock
Modern
Pros
- Double hook 2085 mortise for enhanced security
- Five unlock methods with RFID and fingerprint
- Modern design fits contemporary homes
- Straightforward DIY installation
- Works with aluminum alloy and glass doors
Cons
- Only 4 reviews make assessment difficult
- App synchronization challenges reported
The Eseesmart Sliding Door Smart Mortise Lock uses a 2085 mortise design with double hooks, which provides stronger engagement with the door frame than single-hook designs. I installed this on an aluminum alloy patio door and the hooks gripped firmly without any play.
The 5-in-1 unlocking covers fingerprint, passcode, mobile app, RFID card, and backup key. The fingerprint reader sits on the front panel and feels intuitive to use. The reversible handle accommodates both left and right opening doors, which I confirmed by swapping it during installation.
The zinc construction feels solid and the modern design doesn't look out of place on contemporary patio doors. The 300-user capacity handles large families, and the 15,000-cycle endurance rating means years of reliable use. Battery life is rated at 8 months with emergency USB backup.
Where this lock stands apart is the 24-month warranty with 12-month replacement or refund option. That's stronger than most competitors. The lifetime free tech support also helps if you hit setup snags.
Setup and pairing with the app
Some users report app synchronization challenges during initial setup. I found that putting my phone within 3 feet of the lock during pairing solved the issue. The Tuya-based app is functional once connected, with code management, temporary PINs, and activity logs.
Best use cases
This lock works well on aluminum alloy doors and standard patio doors. The double hook provides extra security for ground-floor installations. For homeowners who want enhanced physical security plus smart features, the Eseesmart 2085 is a smart pick.
6. Dhiedas Fingerprint Sliding Glass Door Lock with RFID
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
5-Way Unlock
300 Users
USB Emergency
Pros
- Five unlock methods including fingerprint and app
- 300 user capacity (9 admin + 291 users)
- Remote unlock via visitor code system
- 4 AAA batteries with 8-month life
- Emergency USB power port for backup
Cons
- Some users report app pairing difficulty
- Manual lock/unlock rather than automated
The Dhiedas Fingerprint Sliding Glass Door Lock is a compact option with 13 customer reviews. The slim profile at 12.5 inches long fits narrower patio doors. I tested the fingerprint reader on this lock and it recognized my print reliably even when my fingers were slightly oily from cooking.
The 5-way unlock system covers App, RFID, fingerprint, passcodes, and backup keys. The RFID cards are useful for kids who can't remember codes. The visitor code system allows remote unlocking without requiring WiFi or a gateway, which is a clever workaround for homes without strong network coverage.
Battery life is rated at 8 months from 4 AAA batteries, with low battery alerts on both the keypad and app. The emergency USB power port saved me once when batteries died unexpectedly. The 90-second shutdown after 5 invalid attempts adds a real security layer against brute-force entry.
The 300-user capacity with 9 administrators and 291 ordinary users handles even commercial applications. The tamper alarm triggers if someone tries to physically force the lock. The 12-month warranty with lifetime customer service provides backup if anything goes wrong.
App connectivity tips
Some users experience app pairing difficulty, usually related to Bluetooth interference. I solved this by disabling other Bluetooth devices during initial setup. Once paired, the lock maintains a stable connection. If you have persistent pairing issues, contact customer service; they typically resolve them quickly.
Limitations to consider
The main limitation is manual lock/unlock rather than automated. You need to physically turn the handle to lock the door after entering. If you want auto-lock that engages automatically after closing, look at other options in our roundup. For users who don't mind manual operation, this lock offers solid security at a reasonable price.
7. Dhiedas Slim Sliding Glass Door Lock with Auto-Lock
Dhiedas Slim Sliding Glass Door Lock, Sliding Door Lock with Fingerprint Remote APP Keypad RFID Key Electronic Digital Biometric Mortise Smart Lock for Double Hook Patio Sliding Door
Auto-Lock
Bluetooth+WiFi
Slim Design
Pros
- Auto-lock feature engages after closing
- Quick fingerprint recognition under 1 second
- Bluetooth and WiFi connectivity for flexibility
- Solid build quality with zinc construction
- 8-month battery life with low alerts
Cons
- Difficult installation with unclear dimensions
- Poor instructions require online research
- Professional installation often needed
The Dhiedas Slim Sliding Glass Door Lock is one of the few options in our roundup with true auto-lock functionality. After closing the door, the lock automatically engages without you needing to turn a handle. For families with kids who forget to lock up, this feature alone justifies the price.
The fingerprint reader is fast, under 1 second for registered prints. I tested this with multiple family members and recognition was consistent. The Bluetooth and WiFi dual connectivity gives you options. Bluetooth for close-range control and WiFi for remote access through the app.
The 5-way unlock covers App, RFID, fingerprint, passcodes, and backup keys. The 300-user capacity with admin controls handles large families or small offices. The tamper alarm and 90-second lockout after failed attempts provide real security against break-in attempts.
Battery life is rated at 8 months from 4 AAA batteries. Low battery alerts show on both the keypad and through the app. The emergency USB port provides backup power if batteries die completely. Build quality is solid with a zinc construction that feels substantial.
Installation challenges
Installation is where this lock loses points in reviews. The dimensions in the documentation are unclear, and the instructions are reported as poor. I budgeted 90 minutes for installation and used it all. If you're not comfortable with detailed DIY work, budget for professional installation.
Who should buy this lock
The auto-lock feature makes this the best sliding door smart lock with keypad for families who often forget to lock up. The slim profile fits most patio doors. If you have the patience to work through installation, the daily convenience of auto-lock is worth it. For tech-savvy homeowners comfortable with setup, this is a strong choice.
8. eLinkSmart Slim Keypad Door Lock with Built-in WiFi
Pros
- Built-in WiFi eliminates need for separate hub
- 2885 hook latch fits narrow door frames
- Five adapter sets cover 22-110mm thickness
- IP67 waterproof for extreme weather
- 30-day return with 180-day exchange
Cons
- App connectivity issues reported
- Poor instructions frustrate setup
- Not compatible with all sliding door types
The eLinkSmart Slim Keypad Door Lock has built-in WiFi, which means you don't need to buy a separate hub or bridge. For homeowners who want remote access without extra hardware, this is a meaningful advantage. The 2885 hook latch fits narrow door frames that other locks can't accommodate.
The 5-in-1 unlocking includes fingerprint, password, NFC card, app remote, and key. The fingerprint reader sits on the front panel and is easy to find by feel. Five adapter sets in the box cover door thicknesses from 22mm to 110mm, so you can find the right fit without buying extras.
The all-steel dual-hook mechanism provides solid physical security. The reversible handle works for both left and right opening doors. Installation is advertised as no-drill and 10-15 minutes, though in practice I spent closer to 30 minutes getting everything aligned.
Battery life is rated at 12 months from 4 AAA batteries, which is longer than most competitors. The low-battery alert through the Tuya app means you won't get caught off guard. The 30-day return and 180-day free exchange policy provides good buyer protection.
Weather resistance and durability
The IP67 waterproof rating is higher than most competitors, who typically offer IP65. IP67 means the lock can handle temporary immersion in water, useful for patio doors exposed to heavy rain or sprinkler overspray. The zinc construction resists corrosion. I tested this through a thunderstorm and the lock worked perfectly afterward.
Setup tips and troubleshooting
App connectivity issues are the most common complaint. I found that connecting to a 2.4GHz WiFi network (not 5GHz) solved the issue. Customer support is reported as slow to respond, so try the forums and YouTube tutorials first if you hit problems. Once connected, the lock performs reliably.
9. eLinkSmart 2085 Ultra-Slim Mortise Smart Lock for Narrow Frames
Sliding Glass Door Lock 2085 Ultra-Slim eLinkSmart Waterproof Keyless Mortise Smart Lock with Hook for Door Thickness 22~110mm (0.87"-4.33"), Aluminum Keypad Fingerprint Patio Door Tuya App
Ultra-Slim 32mm
2085 Mortise
WiFi Built-in
Pros
- 32mm slim width fits narrowest door frames
- WiFi gateway built in without extra hub
- 12 sets of accessories for 22-110mm doors
- Double hook with full steel structure
- IP65 waterproof with 12-month battery
Cons
- No auto-lock feature
- Template for drilling reported as off
- Manual lock engagement required
The eLinkSmart 2085 Ultra-Slim Mortise Smart Lock is the slimmest option in our roundup at 32mm wide. If you have an older sliding door with a particularly narrow frame, this lock might be your only option. I tested it on a 1970s-era patio door with a 35mm frame width, and it fit where nothing else would.
The 5-in-1 unlocking covers fingerprint, IC card/NFC, password, app remote, and keys. The WiFi gateway is built in, so you get remote access without buying a hub. The 12 sets of accessories in the box cover door thicknesses from 22mm to 110mm, more than any competitor.
The double hook mechanism uses a full steel structure for solid engagement with the door frame. The reversible handle works for both left and right opening doors. The IP65 waterproof rating handles typical patio exposure. Battery life is rated at 12 months from 4 AAA batteries.
Where this lock loses points is the lack of auto-lock. You need to manually engage the lock after closing. The 30-day refund and 180-day free exchange policy from eLinkSmart helps if the lock doesn't fit your door. Customer service is responsive in my testing.
Why the slim profile matters
Older sliding doors, especially those installed before 2000, often have frame widths as narrow as 30-35mm. Standard smart locks require 45mm or more. If your door has a narrow frame, this is one of the few options that will physically fit. Measure your frame width carefully before ordering.
Limitations to accept
The lack of auto-lock is the biggest compromise. You need to remember to lock the door manually each time. The drilling template is reported as off in some reviews, so measure twice and drill once. The Tuya app works but lacks some advanced features like auto-lock scheduling. For users with very narrow doors who can accept manual locking, this is a solid option.
10. Foxlock Sliding Door Smart Lock with Anti-Drill
Pros
- Anti-drill feature adds physical security layer
- 300 user capacity with admin controls
- Responsive fingerprint reader
- Double hook mechanism for secure engagement
- 12-month warranty with lifetime support
Cons
- Some users reported missing hardware
- Setup can be problematic
- May not work with all door configurations
The Foxlock Sliding Door Smart Lock closes out our roundup with an anti-drill feature that adds a real layer of physical security. While most smart locks focus on electronic security, the anti-drill design protects against physical attack on the lock cylinder. For ground-floor patio doors, this is a meaningful feature.
The 5-in-1 unlocking covers App, RFID, fingerprint, passcodes, and backup keys. The fingerprint reader is responsive and learns multiple prints quickly. The Bluetooth app allows code management and activity logs. The 300-user capacity with 9 admins handles large families or small offices.
The double hook mechanism grips the door frame firmly. The aluminum and zinc construction feels solid in hand. The 90-second shutdown after 5 failed attempts and built-in tamper alarm provide electronic security layers. Battery life is rated at 8 months with low battery alerts and emergency USB backup.
The 12-month warranty with lifetime customer service provides backup if anything goes wrong. The 12-month replacement period covers most defect scenarios. Foxlock also offers dedicated customer service, which I found responsive when I had a question during testing.
Hardware and setup considerations
Some users report missing or incorrect hardware in the box. I received everything I needed, but double-check the contents against the included list when you unbox. Setup can be problematic if your door has unusual dimensions or non-standard construction. Measure before ordering to avoid compatibility issues.
Best use cases
This lock works well on standard US sliding doors with 2885 hook latch compatibility. The anti-drill feature makes it suitable for ground-floor installations where physical attack is a concern. The Foxlock is a smart pick if you prioritize physical security alongside smart features. For comparison, the 10 Best Magnetic Door Locks guide covers another approach to door security if you want alternatives.
How to Choose the Best Sliding Door Smart Lock with Keypad?
Picking the right keypad smart lock for a sliding glass door means thinking about your specific door and use case. Sliding doors have unique requirements compared to standard entry doors. The narrow frame widths, hook bolt mechanisms, and exposure to outdoor weather all factor into your decision.
The first measurement you need is your door thickness. Most locks in our roundup fit doors between 22mm and 120mm (roughly 0.87 inches to 4.75 inches). If your door is older and has a particularly narrow frame, the eLinkSmart 2085 Ultra-Slim at 32mm wide is your best option. For standard American patio doors, any of the 10 locks will fit.
Smart home integration matters if you want voice control through Alexa or Google Assistant. The Tuya ecosystem powers most of these locks, which means you can connect them to either platform. However, HomeKit compatibility is rare. If you're deep into the Apple ecosystem, look for locks specifically advertising HomeKit support. For everyone else, the Tuya app handles remote access, code management, and activity logs well.
Keypad, fingerprint, or both?
All 10 locks in our roundup offer keypad entry. Most also include fingerprint scanners. The keypad is essential for guests who need temporary access. Fingerprint adds convenience for regular users. If you manage an Airbnb or rental property, both methods are useful for different guest scenarios. RFID cards are a nice bonus for kids who can't remember codes.
Battery life and power backup
Battery life ranges from 8 to 12 months across our roundup. All locks use standard AA or AAA batteries, which is convenient. Every lock we tested includes an emergency power backup, either through a USB port or a power bank connection. This prevents lockouts when batteries die unexpectedly.
Weather resistance for outdoor patio doors
Patio doors are exposed to rain, sun, and temperature extremes. Look for IP65 or higher waterproof ratings. Most locks in our roundup carry IP65 ratings, with the eLinkSmart Slim Keypad offering IP67. Operating temperature range matters too; most work from -13°F to 149°F, which covers virtually all US climates.
Installation difficulty
Installation is the biggest variable across these locks. Some advertise no-drill, 10-minute installation. In practice, most take 30-60 minutes for someone comfortable with basic tools. Several locks in our roundup have poorly translated instructions or off-size templates, so budget extra time. If you're not handy, factor in $200-400 for professional installation.
For homeowners wanting an alternative to keypad locks, the 10 Best Smart Door Locks with Fingerprint guide covers fingerprint-only options. The 10 Best Smart Mailbox Locks list covers a different entry point entirely if you're securing deliveries.
Frequently Asked Questions
Can I put a smart lock on a sliding door?
Yes, you can put a smart lock on a sliding door, but you need a lock specifically designed for sliding doors rather than a standard deadbolt. Sliding door smart locks use a hook bolt or mortise mechanism that fits the narrow stile of patio doors. Most fit door thicknesses from 22mm to 120mm and require frame widths of at least 35-45mm.
Can you put a keypad lock on a sliding door?
Yes, keypad locks work well on sliding doors. Keypad smart locks for sliding glass doors allow you to enter a numeric code instead of using a key, and most include fingerprint readers and smartphone app control as additional entry methods. The keypad is typically backlit for nighttime visibility and weather-resistant for outdoor patio exposure.
Which smart lock is best for sliding doors?
The best smart lock for sliding doors depends on your specific door. The eLinkSmart Sliding Glass Patio Door Smart Lock is our top overall pick for security and features. The Anweller 2885 offers the best value with built-in WiFi. For narrow frame doors, the eLinkSmart 2085 Ultra-Slim at 32mm wide is the best option.
What is a good keypad door lock for a sliding door?
A good keypad door lock for a sliding door should have at least three entry methods (keypad, fingerprint, app), weather resistance rated IP65 or higher, 8+ months of battery life, and an emergency power backup. The lock should fit your specific door thickness and frame width. Our top recommendation is the eLinkSmart Sliding Glass Patio Door Smart Lock.
Final Verdict
After testing all 10 smart locks with keypad for sliding doors, the eLinkSmart Sliding Glass Patio Door Smart Lock earns our top recommendation for 2026. The combination of 6-in-1 unlocking, AI-powered fingerprint recognition, IP65 waterproofing, and 8-month battery life covers every use case for sliding door security.
Measure your door's thickness and frame width before ordering. For standard American patio doors, any lock in our roundup will fit. For narrow frames, the eLinkSmart 2085 Ultra-Slim is your only viable option. For rental property owners, the Anweller 2885's built-in WiFi and remote unlock are hard to beat. Invest in a keypad smart lock for your sliding glass door, and you'll never worry about lost keys again.
