The strength and protection a deadbolt provides is well know and has become North Americas most common and primary form of home door defense. The strength and protection of the dead bolt is due to the fact that the bolt when locked actually extends into the frame of the door and passes through a steel strike plate that is in most cases secured by 1”-2” wood screws.
While the deadbolt is highly effective in most cases, it is 100% useless if someone you don’t want in your home has a key or is able to use the “Bump Key” method or other lock picking techniques of unlocking the deadbolt.
