How to choose
Pick the best small smart lock for your door
Start with the form your door already uses. A knob lock, like the KLLOQUE and the TMEZON, replaces a knob, while a deadbolt lock, like the eufy, the Yale August and the Level, works with a deadbolt setup. Check the fit figures for the pick you want: the KLLOQUE fits backsets of 2-3/8 inches and 2-3/4 inches, and the Level fits standard US doors from 1.75 inches to 2 inches thick. The Yale August installs on the inside of the door without replacing the existing deadbolt.
Compare unlocking methods and remote access
Count the ways each lock opens. The KLLOQUE offers fingerprint, password, app Bluetooth control and a backup key. The TMEZON adds IC cards to fingerprint, passcode, app control and physical keys. The eufy uses built-in Wi-Fi for remote control with no hub, while the KLLOQUE and the TMEZON use Bluetooth apps, with a gateway needed for remote access on the KLLOQUE and a Tuya Gateway needed for Wi-Fi on the TMEZON. The Level needs a Matter hub or Level Connect Wi-Fi Bridge for remote access.
Check power, auto-lock and what is included
Auto-lock is on the KLLOQUE, the TMEZON, the eufy and the Yale August, but the timing and the power differ. For power, the KLLOQUE uses a 400mAh rechargeable battery rated for up to 1 year, while the eufy runs on 4 AA batteries for up to 5 months. Check the box too: the Yale August box includes DoorSense and the keypad, and the Level box includes 2 NFC key fobs, 2 physical keys, a CR2 battery and an ANSI-standard strike plate.
