ABSTRACT:
A deadbolt locking system for use on existing locks having a bolt longitudinally moveable between extended and retracted positions by a manual operator mechanism. The system includes an engaging member defining a torque blade key that telescopes a torque blade that extends transversely through a crank hub of the bolt moving mechanism and to a thumbturn. An actuator having a moving member that moves between extended and retracted positions is operatively connected to a connecting rod that is also connected to a torque blade key. The actuator is connected to a signal receiver that receives a signal sent by a transmitter. Upon receiving the signal, the receiver supplies current to the actuator to energize the actuator to move the moving member and connecting rod. This movement rotates the torque blade key to rotate the torque blade that rotates the bolt moving mechanism to move the bolt longitudinally between its extended and retracted positions.
