A locking device, suitable for walk-in freezer doors, automatically locks when the door is closed, allows the door to be pulled open from the outside only when a proper key is inserted and rotated 90 DEG , and always allows the door to be opened from the inside by pushing on a manual actuator. The locking device includes a strike mounted on the door frame, an outside plate assembly including a rigid handle and lock cylinder, and an inside plate assembly including a bracket supporting a spring loaded bolt, an enabling mechanism in the form of a collapsible linkage coupled to the bolt, a manual actuator, and a cover.
