Abstract
The disclosure describes a locking system for a door with a mortise pocket. The locking system has a mortise case within the mortise pocket. The mortise case defines an alignment hole. The locking system also has a gear box with a worm gear that defines a notched passage that receives a lock knob shaft. A worm within the gear box is coupled to a motor that rotates the worm. The worm engages the worm gear such that the worm gear rotates when the worm rotates. A control board in the gear box is adapted to receive electronic signals and transmit them to the motor to cause the motor to rotate the worm. The gear box also has a worm gear hub that defines a keyed passage and a hub tab. The worm gear hub fits within the notched passage and the keyed passage receives the lock knob shaft. The worm gear also has two notches that the hub tab contacts individually when the gear hub rotates within the notched passage.
