It is often found that some users and friends, home door lock damage is often caused by improper use or maintenance. Do not always use wet cloth to wipe the door lock, otherwise it is easy to enter the accessories, parts rust, easy to break down!

If the door frame deformation or its causes can not be restored, can start from the door frame, the latch corresponding expansion, so that the door can be restored to normal fluency.
