The smart lock operates on battery power, and you will receive low-battery warnings weeks before the battery is depleted. If the lock's power runs out, you can still use the physical key to lock and unlock the door. In situations where the battery is completely depleted and there is no key available, you can use a micro USB cable and a power bank to temporarily power the smart lock through the emergency charging port at the bottom of the device.
