While there are many advantages to smart locks, these advanced locks aren’t usually compatible with sliding doors. That’s why we’ve reviewed eight of the best smart lock models that are fully compatible with sliding patio doors!

1) Port Tower Smart Lock For Sliding Doors

Port’s Tower is a slim smart lock with a contemporary design. With this lock, you’ll be able to add fantastic security to doors where space is a concern – including swinging and sliding doors. This smart lock from Port uses Bluetooth and Wi-Fi communication protocols, allowing you to control your sliding door’s smart lock remotely.

The Tower smart lock features an integrated keypad, which works with single-use, temporary, and permanent passcodes. The passcodes and users can be managed directly from the official Port app. In addition to the keypad, this lock is also equipped with a nifty card sensor for easy access.

Like other smart locks, you can also manage your lock’s activity and security settings from the Port app. For example, if someone has used a temporary or permanent passcode to unlock your sliding door, you’ll be able to see who used their code directly on the app – even if you’re not at home!

This slim mortise lock will fit on standard wood, metal, and glass doors. However, when purchasing the smart lock, you’ll be able to select a finish, door thickness, backset, and door function. For the door function, you need to ensure you purchase the Tower lock compatible with sliding doors.

In terms of door thickness, there are five different buying options: 1-3/8”, 1-3/4”, 2”, 2-1/4”, and 2-1/2”. For the lock’s backset, which is the distance from the front of the lock to the center of the lock’s spindle, there are also five choices: 28mm, 30mm, 35mm, 45mm, and 55mm. Finally, you’ll be able to choose between a Satin Black or Satin Stainless Steel finish for your smart lock.
