  • Patent number: 6032500
    Abstract: A kit for retrofitting a door with a remotely controllable locking mechanism having a combination key-operated deadbolt lock and door knob latching lock for a door. A housing for the operating parts is insertable in a mortised pocket or cavity in the latch edge of the door or it may be attached to the exterior surface of the interior well of the door. The electronics to operate the mechanism sends a signal to a receiver installable in the wall near the locks. Power is supplied to solenoids to simultaneously activate the locking and unlocking mechanisms of the deadbolt and the door knob latching lock when the kit is assembled in the door. Manual key overrides are provided for the deadbolt and for the latch.
