1. When choosing a fire door lock, pay attention to the lock that moves in the same direction as your home. Also pay attention to the width of your door frame. Ball locks and hand locks cannot be used on doors smaller than 90CM. Pay special attention when installing the door lock. You can only install it by breaking the end with the safety. Never break the end with the key.

2. Next, don't drop oil into the lock cylinder, but if the key starts to fail, you can install some pencil lead in the keyhole. There is also a special reminder: then users can't unlock in life, but it is best to use pencil powder (graphite lubrication), and then insert the key to turn it a few times to restore smoothness. But if you really want to put oil, it is best to put volatile oil, and there is no residue afterwards.

Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. But we can start to feel the quality of the lock.
