The capacitive fingerprint reader distinguishes between 50 stored fingerprints with a false acceptance rate below 0.001%, opening in 0.3 seconds. A 4-8 digit backup keypad and a physical key provide three alternative unlock methods during battery failure or power loss. Auto-lock timer closes the deadbolt 1-10 minutes after unlocking, preventing accidental leave-aheads. The Wyze app sends tamper and low-battery alerts to your phone and logs every entry event. A Wyze Gateway (sold separately or part of Wyze Security) adds remote lock/unlock from anywhere over Wi-Fi.
