How can I open my locker if I forget my password or my battery is dead?

1, the battery is dead. Is the cupboard door locked? Just use the spare battery box or use the emergency hole to unlock the lock. Please replace the battery immediately after opening it.

2. One possibility is that the hinge has been used for a long time and needs to be replaced due to functional degradation;

3. The other is that the installation is not accurate enough, or the door panel is relatively heavy and the hinge is relatively small, which will make the hinge unable to bear the weight of the door panel and make a sound.
