What if the room door is unlocked?

Problems that cause the door lock to fail to lock:

1. The lock shaft is partially stuck at the lock shaft outlet.

2, often slam the door, causing the lock shaft to bump.

3. The outlet of the lock groove is depressed due to long-term stress and deformation.

4. The friction between the lock shaft and the lock groove makes the lock shaft dull and the surface rough. ?

Treatment method:

1. Lubricate the lock shaft. If there is no lubricating oil, use some cosmetics instead. These cosmetics are rich in oil.

2. Hold the lock shaft in a vise, and then strike the vise hard with a hammer or stone to convert the force and restore the lock shaft to its original state. ?

3. Clamp the sunken lock groove with a vice, put a hard object under the vice as a fulcrum, and then press the vice until the lock groove returns to its original state. ?

4. The dullness of the lock shaft is generally irreversible, but we can apply grease to the contact between the lock shaft and the lock groove to prevent the lock shaft from being damaged again.
