Abstract: A deadbolt mechanism including a lock out mechanism that functions to disable the operation of the deadbolt from at least one side of the deadbolt mechanism. The deadbolt mechanism includes a deadbolt, key cylinder, housing, turn knob and a shaft that connects the key cylinder and turn knob. To place the deadbolt mechanism in lock out mode, a release mechanism is actuated and the turn knob is pulled outward away from the door. By pulling the knob outward, the shaft engages a portion of the housing which prevents rotation of the shaft and thereby prevents movement of the deadbolt from the lock-out position.

Abstract: A system for controlling access to a securable area. The system includes a transmitter, a receiver, a logic circuit, an energy storing device, and a locking mechanism. The transmitter remotely transmits a signal that is selectively received by the receiver. The receiver includes an active and an inactive state. The logic circuit is in communication with the receiver and includes an active and an inactive state. The logic circuit is in communication with the energy storing device, which is in communication with the locking mechanism. When the receiver receives the signal from the transmitter, the locking mechanism selectively allows access to the securable area.
