Emergency Power
In case of system malfunction or inability to unlock the door from outside, you can connect an external power source (such as a 5V USB-C power bank) to provide temporary power.
Powering the lock via USB-C allows you to enter your PIN, fingerprint, or other access methods to unlock the door.
After unlocking, replace the batteries promptly to ensure continued operation.
