ABSTRACT:
For use with a deadbolt lock having an actuating knob, a lock plate and a tailpiece engaging the actuating knob, a lock accessory comprises an intermediate plate for location between the lock plate and a door on which the lock is provided. The intermediate plate has an opening through which the tailpiece extends and a manually actuatable locking member mounted on the intermediate plate for selectively preventing and permitting rotation of the tailpiece. The locking member is displaceable into a first position, in which the locking member is in locking engagement with the tailpiece, and a second position, in which the locking member is displaced out of locking engagement with the tailpiece, and has a portion which can be manually engaged for effecting the displacement of the locking member between the first and second positions.
