1. During the use of the door lock, regularly (once every six months or once a year) or when the key is not smoothly inserted and unplugged, do not use any liquid oil such as edible oil as lubricant to avoid grease sticking to the spring spring, resulting in the door lock can not be rotated and cannot be opened. Usually, you can use the end of the pencil at home to paint on the key, and then insert the lock cylinder and turn it a few times to play a role in lubrication. In addition, professional lubricants and rust inhibitors for door locks are also available. Some zinc alloy and copper locks, installed on the door for a long time will be found to have "spots", such a phenomenon does not belong to rust, but to oxidation, if this happens, as long as the surface wax spray rubbing can remove the spots.
2. In the process of using the lock, it is necessary to pay attention to the lock cylinder not to get into the rain and water, because there is a small spring in it that will rust and fail to be flexible, which will naturally damage the normal use of the lock.
3. When the deadbolt or the safety anti-deadbolt is exposed, do not hit it violently to avoid damage to the deadbolt and door frame.
4. Don't use the key to open the door directly, the key turns the door lock, and the lock heart does not return to its original position to directly pull the key to open the door, and the lock will not be long in protest with you to say goodbye.
5. The anti-theft door has a lattice type, which is used to stretch the wire into the oblique lock handle of the automatic lock, and the door is opened, and the lattice type should be maintained during use. However, the lock body and handle should not be wiped with a damp cloth to avoid rust.
6. When the door lock is not well opened, spray some lubricating oil on the diagonal tongue to ensure its lubrication effect.
7. When closing the door, it is best to hold the handle, screw out the lock tongue or screw it into the lock body, close the door and then let go, and do not "bang" the door hard, otherwise it will reduce the service life of the lock.
8. Always keep the lock body clean to prevent foreign objects from entering the lock cylinder slot, resulting in rolling when opening, and even the lock cannot be opened.
