Abstract
Abstract A remotely controllable locking mechanism for a combination key-operated deadbolt lock and door knob latching lock for a door. A housing for the operating parts is inserted in a mortised pocket or cavity in the latch edge of the door. The electronics to operate the mechanism sends a signal to a receiver installed 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. Manual key overrides are provided for the deadbolt and for the latch.
