Door lock selection tips

1. Choose a brand-name lock produced by a manufacturer with quality assurance.
2. Pay attention to the lock that is the same as the opening direction of your door.
3, pay attention to the width of your home door frame, the ball lock and handle lock can not be less than 90cm door.
4. Pay special attention when installing the door lock: Only remove the end with insurance to install it. Never remove the end with the key. It is best to read the manual carefully.
5, do not drop the oil into the lock, if the key is not flexible, you can put some pencil core scraps into the key eye.
6. If you accidentally rotate the house insurance 90 degrees in time to become permanent insurance, you can only use the key to open. 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.
8. When closing the door, it is best to hold the handle, screw the lock tongue into the lock body, and then release the hand after closing the door. Do not force the door, otherwise it will reduce the service life of the lock.

For places that can be used at home without locks, you don't have to choose expensive ones, as long as you have passed the nationally verified manufacturer's products. In addition, for kitchens and bathrooms with small spaces, the handles of the door locks are preferably smooth or rounded, which is not easy to injure.
