When a new house is repaired or the door lock fails, buying a good door lock becomes the most troublesome thing nowadays. Of course, some friends often first think about whether or not they are supporting the door when they buy the door lock. But did you consider the security of the lock? The security of the door lock and unlocking also need to be included in the purchase conditions. Here are some guidelines to consider when buying a door lock:
First, select brand-name locks produced by quality-assured manufacturers.
Second, pay attention to buy and your door open the lock in the same direction.
Third, pay attention to the width of your home's door frame, ball lock and handle lock can not be less than 90cm on the door.
Fourth, pay special attention to the installation of the door lock: only with the end of the insurance removed to install, do not remove the end with the key to install, it is best to read the instructions carefully.
5. Do not drip oil into the lock cylinder. If the key is not flexible, insert some pencil shavings into the keyhole.
6. If the insurance is accidentally rotated in the house at 90 degrees, it will be permanent and it can only be opened with a key. Just rotate the insurance counterclockwise 90 degrees to restore it.
7. Do not wipe the lock body and handle with a damp cloth to prevent rust.
8. It is best to hold the handle when closing the door, and screw the lock tongue into the lock body. After closing the door, do not let go. Do not use force to hit the door, otherwise it will reduce the service life of the lock.
