5 Best Smart Locks (2025), Tested and Reviewed

The best smart locks can help anyone who constantly misplaces keys or who frequently wonders whether they locked the front door. I am in the latter camp. After years in apartments, I recently moved to a large enough house that checking whether the door is locked can feel like a chore, especially once I'm all cozy in bed. Installing a smart lock doesn't mean throwing away your house keys--you probably still want to bring them with you. These locks are all about convenience, offering multiple ways to enter, like a passcode via a keypad, fingerprint scanning, or through an app. You can easily share codes with friends and family, so no need to fuss with crappy key copies, and you can usually set them to auto-lock when the door closes.
