Laiwu Lock Repair Company reminds you how to use and maintain door locks:

　　1. Never drip engine oil into the lock core. If it is not flexible to open it with a key, you can put some pencil lead chips into the keyhole.

　　2. If the indoor safety of the spherical door lock is inadvertently rotated 900 clockwise, it will become a permanent safety certificate. At this time, it can only be opened with a key, and it can be restored by rotating the safety 900 counterclockwise.

　　3. In normal use, if there is dirt, it can be removed with a dry cloth (or with a little water), and it is forbidden to scrub with chemicals such as detergent. Otherwise, damage to the protective film of exposed parts will cause fading.

　　4. When closing the door, it is best to hold the handle, screw the locking bolt into the lock body, and then let go after closing the door. Don’t slam the door hard, otherwise it will reduce the service life of the lock.

　　To sum up, the reminder of the lock repair company hopes that everyone must take protective measures.
