Other models we tested

In our search for the best smart lock, here are some of the other products we've tested:

Nest Yale Lock: Nest and Yale teamed up for a smart lock centered on Google. This $ 279 smart door lock has the same look as previous Yale models, but is not as good at home automation.

Hampton Connected Array Door Lock: This $ 299 lock has a solar-powered backup battery and built-in Wi-Fi, but it's expensive and does not work with HomeKit or Google Assistant.

Kwikset Kevo Bluetooth DeadboltKevo's $ 222 second-generation Kwikset is a good Bluetooth smart lock and a simple solution to comfort your door if you do not need remote access. If you do, you will need to purchase the Kevo Plus Connection Module. You can use the mobile app or the key ring for keyless entry.

Schlage Sense Bluetooth Deadbolt: Schlage's $ 175 Smart Sense Lock is affordable, but it's hard to install and as easy to install as its Encode brother. You will also need a Schlage Wi-Fi adapter to connect to Google Assistant or Alexa.

Things to remember

Smart locks are convenient, but it's important to remember that this is primarily a security feature. It is important to take security features seriously. Use a PIN code for any voice unlocking and make sure to give only access codes to open the door to trusted people. Activating the auto-reclosing feature is also a good idea, so the door will lock behind you if you forget.

If your smart home is based on Wi-Fi voice assist and you do not use hubs, I'd recommend a lock that works with Wi-Fi (or at least one Wi-Fi adapter). Determine whether you want a keyboard and can replace your deadbolt (you'll need a new physical key), or prefer a simpler, newer design.

Whatever intelligent lock you choose, adding one to your smart home offers many benefits. With these tips and the best smart lock on your door, access management for family members, roommates, service providers and guests is a kid's game.
