Matters needing attention in the use of door locks

Some people use great force when opening the door lock, which is easy to damage the door lock. Therefore, it is suggested that when you use the door lock at ordinary times, turn the door handle gently first, and then slowly push the door open, so as to avoid the door lock colliding with the wall and causing the door lock to be damaged.

No matter whether the door lock is open or closed, the lock body should be turned, which can avoid the inflexible phenomenon of the lock body because it has not been turned for a long time. In addition, when rotating the lock body, it is necessary to ensure that there is lubricant at the rotating part of the lock body, which can reduce the wear of the lock body and increase the service life of the lock body.

If the door lock is too tight or not smooth, you can drop a proper amount of lubricant into the keyhole. However, because the lubricant is easy to be contaminated with dust, it is easy to accumulate dust in the keyhole after dripping. Therefore, it is not necessary to add lubricant to the keyhole. Usually, the pencil can be pressed on the key and then put into the keyhole through the key.
