What this lock does

The eufy Smart Lock E31 is a Wi-Fi smart deadbolt in black that unlocks by fingerprint, keypad, app, physical key or voice. It connects directly to Apple Home, Google Home, Alexa and SmartThings without a separate bridge, giving the whole family multiple ways to enter in under 0.3 seconds.

Check before you buy

Your door must fit the 6.89 x 2.76 x 1.3 inch body and accept a standard deadbolt cutout. You need a 2.4 GHz Wi-Fi network for the lock to join your home hub. The 10000mAh rechargeable battery is built in, so confirm you can reach the lock with a portable charger for emergency power if the 14-month charge runs low.

Who this suits and who it doesn't

Households that want keyless entry tied to Apple Home, Google Home, Alexa or SmartThings will benefit from the fingerprint sensor and auto-lock feature. Buyers who need a mortise lock, a handle-set style, or a lock that works with a proprietary alarm panel should look elsewhere.
