Using the Emergency Power Supply Port:

Temporary solution:

If you encounter a situation where the smart lock is out of power and cannot be unlocked, look for the emergency power supply port located beneath the panel. Connect a power bank to the lock for temporary power supply, enabling normal unlocking. However, please note that this method does not charge the battery. Therefore, after unlocking, it is still necessary to promptly replace the battery or recharge it.

In conclusion, regular battery level checks, choosing appropriate battery brands, maintaining a charging schedule, and using the correct charger and cable are crucial for ensuring proper power supply to smart locks. While the emergency power supply port can serve as a temporary solution, timely battery replacement or recharging is essential for long-term usage.
