A smart lock offers convenience, security, automation and peace of mind. But which smart lock option is right for your door?

Things to remember
Smart lock technology adds convenience, but it's important to remember that this option is first and foremost a security device. It's important to take security features seriously. Use a PIN code for any voice control unlock, and make sure you only give access codes to unlock the door to people you trust. Enabling the auto relock feature is also a good idea, so the door will lock behind you if you forget.
If your smart home is based in Wi-Fi voice assistants and you don't use hubs, I'd recommend a lock that works with your Wi-Fi network (or at least a Wi-Fi adapter). Consider whether you'd like a keypad and can replace your existing deadbolt (you'll need a new physical key for locking), or prefer a simpler, retrofit design.
No matter which smart lock you choose, adding one to your smart home offers a lot of advantages. With these tips and the best smart lock on your door, managing access for family members, roommates, service providers and guests is a breeze.
