Abstract

A multi-point door lock unit is disclosed. In one preferred form the door lock is for use with a hinged or swinging door. The door lock unit has a latch, a deadbolt, and extension bolts extendable away from the door. The door lock may be used with a double door entry whereby one door is an active door having the lock unit and a second door is a passive door having a passive lock unit. Further, the door lock unit has an activation button that prevents extension of the deadbolt and the extension bolts unless the activation button is depressed.
