At the beginning, we quickly removed the broken old doorknob. Usually the stainless steel anti-theft doorknob is passed through the room as the start of the removal. Since the two screws that fix the handle are in the open, only the key screws It's OK if you remove it.
The removal steps are often very simple. First open the door, press the outside firmly with four fingers, press the inside with your thumb (at the same time call someone to help hold the outside point), use a screwdriver to remove the screw, beware! The moment you can remove it immediately, you have to press it firmly. Because the door handle has a built-in spring, if you are not careful, it will rebound and hurt yourself, which is not worth the loss.
