Versatile multi-mode access: Supports five distinct ways to unlock—including quick fingerprint recognition, custom passcodes, IC fobs, mobile app controls, and physical keys.
Ideal for rental property hosts: Effortlessly issue temporary, recurring, or single-use PIN codes remotely using the companion smartphone app.
Fast 3D biometric response: Scans and unlocks in under 0.3 seconds for fast, keyless home entry.
Straightforward DIY setup: Installs quickly on standard residential doors using standard household tools without requiring professional locksmith assistance.
Emergency power backup: Features an external micro-USB port on the lower housing to power up the lock temporarily if the primary AA batteries run completely flat.
Wi-Fi features require an extra accessory: Remote management out-of-range and voice integrations with Alexa or Google Assistant demand purchasing a separate Sifely Wi-Fi Gateway.
Uses micro-USB for emergency power: Relies on an older micro-USB standard port for emergency jump-starting rather than a modern USB-C interface.
AA batteries not included: Operates on four standard AA batteries that must be supplied separately out of the box.
