Precautions for removing the door lock:

1. Be sure to measure the lock core size of the door lock first, and then go to the hardware store to buy the lock core with the same size for easy replacement. If you buy the lock blindly, if the size is not ready, the newly bought lock core can't be wired, which will be a very troublesome thing.

2. Sometimes, due to the gravity of the door leaf itself or the loose leaf of the door, the door leaf sinks and the door cannot be locked or opened smoothly. At this time, it is often very difficult to open and lock the door with a key. At this point, don't twist the key hard, so as not to break the key and increase the trouble.

3. Check the reason first. If the door leaf sinks due to loose loose loose leaves, the loose loose leaves should be fixed firmly with screws. If the door frame is deformed or unrecoverable due to its reasons, we can start with the door frame and expand the lock tongue accordingly, so that the door lock can be opened and closed normally and smoothly.

Generally speaking, unless it is a special case, the door lock will not be removed. However, if it is really necessary to replace the lock core, it is necessary to carefully remove the lock step by step, so as not to damage the appearance of the lock and affect its beauty.
