Smart locks eliminate the need for physical keys while adding features like remote access, auto-locking, guest codes, and activity logs. They are perfect for families who want to give kids their own access codes, Airbnb hosts managing guest access, or anyone tired of fumbling for keys at the door.
Each smart lock was installed and used daily for 6 weeks. We tested unlock reliability in various weather conditions, measured lock and unlock speed, evaluated app quality, tested smart home integrations, and checked battery life. We also attempted to tamper with each lock to assess physical security.
Retrofit locks like the August Wi-Fi install over your existing deadbolt and take just minutes to set up. You keep your current keys as backup. Full replacement locks like the Yale Assure replace your entire deadbolt, offering a cleaner look and typically more features like built-in keypads. Both approaches are secure.
The best smart locks work with your existing ecosystem. Apple HomeKit users should look for Home Key support (August, Yale, Schlage, Level). Google and Alexa users have the most options. Matter support is growing and will eventually provide universal compatibility across all platforms.
