The lock has a Grade B product safety level and a Grade C lock cylinder safety level. For power, the lock utilises eight AA batteries, and in the event of dead batteries, the lock can be powered by the built-in USB-C port supplying 5v, presumably from some form of power pack you might use with your phone.
In terms of the lock itself, it’s designed to fit doors that use a mortice type lock, which is more widely available in Europe. As before, the N100 comes with a variety of ways to unlock it, including – for traditionalists – a mechanical key, voice or app control using Siri or the Aqara or Home apps, passcodes via the built-in keypad, fingerprint unlock via the sensor built into the handle, as well as NFC. The lock can store up to 50 fingerprints, and 50 keycodes. The NFC option uses a keycard that can be purchased separately from Aqara.
