How to maintain door locks?

Unlike commercial hardware standards, civilian hardware accessories are prone to many problems over time. Especially door locks, which operate under high loads, have a long service life and may inevitably experience some malfunctions. It is often found that some users find that the damage to their home door locks is often caused by improper use or maintenance.

Some precautions for door lock maintenance:

lubricant

Some friends often like to drip some lubricating oil into the lock hole when the door lock becomes rough or tight, which may immediately make the door lock smooth. However, because the oil is prone to sticking dust, it is easy to accumulate dust in the lock hole in the future, forming oil putty, which in turn makes the door lock more prone to malfunction.

The correct solution is to sharpen some pencil or candle fragments, blow them into the inside of the lock cylinder through a thin tube, and then insert the key and rotate it repeatedly.

Difficulty opening the door

Sometimes, due to the gravity of the door leaf itself or the loose leaf of the door, the door leaf sinks, resulting in difficulties in locking or opening the door. At this time, it is often very difficult to open and lock the door with a key. At this time, do not forcefully twist the key to avoid breaking it and adding trouble.

The correct solution is to first investigate the cause. If the door leaf sinks due to loose hinges, the loose hinges should be fixed tightly with screws. If the door frame is deformed or cannot be restored due to its reasons, you can start with the door frame and expand the lock tongue accordingly. This way, the door lock can be opened and closed smoothly.
