Lock maintenance:

1. Do not get the lock in the rain. Flushing, because there is a small spring inside, it will rust and fail;

2. When the key is not easy to insert or withdraw, spray some light lubricating oil, (such as w40) 

3. Some locks cannot be refueled, (rarely) such as the locks with mother-and-child beads;

4. When the door lock does not open or close, spray some lubricating oil on the diagonal tongue;

5. Automatic lock (three-stage. four-stage. five-stage) should have some slight gaps and not too tight, (for example, the door needs to be opened by hand when unlocking) the lock is easy to break;

6. The door gap should not be too big, it is easy to be opened and shaking;

7. The anti-theft door has a lattice type, and the anti-theft wire extends into the diagonal lock handle of the automatic lock to pull the door open;

8. Don't use the key to open the door directly, turn the key to open the door lock, and pull the key to open the door without returning to the original position. The lock will soon protest and say goodbye to you.
