Multi-Point Door Locking Systems

Updated on June 30, 2011

Most locking systems are single-point locking systems, which is to say they lock into a single plate on the frame of the door. Single-point locks include most cylindrical, tubular, and mortise locks. An apartment door might have a two-point locking system such as a keyed cylindrical lock and a keyed deadbolt on the same door, but these kinds of locks only secure one side of the door. True multi-point locking systems secure two or more sides of the door. Following are some examples.

      I do home repair and remodels and I have a homeowner that just had their house broken into. They want to upgrade their door and locking mechanism. This article gives some great ideas.
