Abstract: A lock system for integrating into an entry door having a vertical expanse and providing simultaneous multi-point locking along the vertical expanse of the entry door. The lock system includes a plurality of conventional deadbolt assemblies, a plurality of pinion gears, and a rack gear. The plurality of conventional deadbolt assemblies are positioned along the vertical expanse of the entry door. The plurality of pinion gears are operatively connected to the plurality of conventional deadbolt assemblies, respectively. The rack gear is operatively connected to the plurality of pinion gears so as to allow the plurality of pinions gears to operate simultaneously and form simultaneously operated pinion gears. The simultaneously operated pinion gears simultaneously operate the plurality of conventional deadbolt assemblies to provide simultaneous multi-point locking along the vertical expanse of the entry door.
