The door lock can't be opened because of external force, probably because the lock tongue inside is unhooked, resulting in the door being stuck, unable to get out and get in. In this case, a good emergency treatment method is to find the locking bolt and pull the dropped screw out of the door to locate it. This method is limited to the case that the door lock cannot be opened due to external material resources.

If the door lock is stuck by a foreign object and cannot be opened, the emergency treatment is generally that the door lock is stuck by a foreign object, and the user should determine whether the door is opened inward or outward. If you drive inside, pull it in hard, if you drive outside, push it in hard.

Precautions:

Generally speaking, the main difference between spherical locks comes from the length of the bolt, one is 60mm and the other is 85mm, so please pay attention to the specification difference when changing clothes.

The holes shall be drilled in strict accordance with the installation dimensions determined in the opening drawing. If the opening is too small, it is easy to cause the extrusion deformation of the door lock and the circuit board, which will lead to the failure of the door lock to work normally after installation and lead to various unexpected phenomena. Be careful when opening the hole, don't open it too wide and don't crack the door. If the opening is too large, the lock body will not be able to cover the hole, which will seriously affect the overall appearance.
