If you’re prone to misplacing your keys or you just want to take home security to the next level, a smart digital door lock could be the answer. These locks can be controlled with a smartphone app and support features such as geofencing, voice activation and a battery residual indicator.


One of the most important features we look for in smart locks is connectivity, which determines whether a lock can be remotely controlled. Bluetooth-only models can only be locked and unlocked when you and your phone are in close proximity to the lock, but WiFi-enabled smart locks offer much more freedom. This includes the ability to set schedules for code access, allowing you to give houseguests or cleaners a temporary code for specific time periods and track when your family members get home from school or work.

Another key feature is whether a smart lock can integrate with other smart devices, such as voice assistants and home automation systems. This allows you to lock your door with your voice, or even control a floodlight or smart speaker when you aren’t at home. We look for these capabilities in all of our picks, with special emphasis placed on those that can seamlessly integrate with the smart home ecosystems we use in our hands-on testing.

Other features to consider include motion sensors that record video on a microSD card, especially useful if you have kids coming home from school or relatives arriving for a visit. You can also program your smart digital lock to unlock automatically when you arrive in proximity to the house, which is handy if you’re carrying a load of groceries or just don’t feel like fumbling with your phone or keys.

We also look at whether the smart lock can be connected to your Wi-Fi, which lets you remotely control and monitor it. This is important if you want to make it part of your home automation setup, and it’s a requirement for some models that offer remote access, such as the August WiFi Smart Lock and Ultraloq U-Bolt Pro. We especially like the way the U-Bolt Pro folds down its front face to reveal a standard keyhole backup, an excellent feature for those who don’t like the idea of having to touch a fingerprint sensor in bad weather.


A smart door lock adds an extra layer of security and convenience to your home. These locks are easy to install and provide you with more options than your standard lock.

First, you should check if there is a physical obstruction in the lock. If there is, remove it. You can also try replacing the batteries in the lock. This will reset the device and may fix it. If this doesn’t work, contact a security company for help.
