When the new house is renovated or the door lock is broken, buying a good door lock has become the most troublesome thing. Now, some friends often think of the door lock when they buy the door lock. But have you considered the safety of the door lock? The convenience of door lock anti-theft and unlocking also needs to be included in the purchase conditions. Here are some suggestions for buying a door lock:
First, choose a brand-name lock produced by a manufacturer with quality assurance.
Second, pay attention to the lock that is the same direction as your door.
Third, pay attention to the width of your home's door frame, the ball lock and handle lock can not be less than 90cm door.
Fourth, special attention should be paid when installing the door lock: only the end with the insurance can be removed to install it. Never remove the end with the key. It is best to read the manual carefully.
5. Don't drop the oil into the lock. If the key is not flexible, you can put some pencil core scraps into the keyhole.
6. If the in-home insurance is inadvertently rotated 90 degrees in time to become permanent insurance, this can only be opened with a key. Simply turn the insurance 90 degrees counterclockwise to recover.
7. Do not wipe the lock body and handle with a damp cloth to avoid rust.
Eight, it is best to hold the handle when closing the door, screw the lock tongue into the lock body, then close the door and then let go, do not force the door, otherwise it will reduce the service life of the lock.
