Claim:
A system comprising: a door having an inside surface, an outside surface, and an edge surface extending between the inside and outside surfaces; a deadbolt assembly comprising: a deadbolt extendable from and retractable into the edge surface of the door; a deadbolt face plate; a deadbolt actuation lever mounted on the deadbolt face plate and being rotatable about a rotation axis between a locked orientation and an unlocked orientation; a blocking apparatus for selectively blocking movement of the deadbolt actuation lever on the door, the blocking apparatus comprising: a base mounting plate mounted on the door, the base mounting plate comprising: an engaging portion positioned against the inside surface of the door, the engaging portion including a first aperture receiving the deadbolt face plate; and a deadbolt receiving portion positioned against the edge surface of the door, the engaging portion including a second aperture receiving the deadbolt when the deadbolt is extended from the edge surface of the door; a mounting shaft mounted on and extending from the engaging portion of the base mounting plate; and a blocking member mounted on the mounting shaft and being movable between a block position and an unblocked position, the block position being characterized by the blocking member blocking movement of the deadbolt actuation lever from the locked orientation to the unlocked orientation when the blocking apparatus is mounted on the door, the unblocked position of the blocking member being characterized by the deadbolt actuation lever being free to move without interference by the blocking member when the blocking apparatus is mounted on the door; wherein the second aperture in the deadbolt receiving portion is configured such that extension of the deadbolt from the door and through the second aperture supports the blocking apparatus on the door in a position such that the deadbolt receiving portion surrounds the deadbolt face plate and retraction of the deadbolt into the door permits removal of the blocking apparatus from the door; wherein the first aperture of the engaging portion is configured such that the engaging portion does not contact the deadbolt face plate to permit removal of the blocking apparatus from the door when the deadbolt is retracted into the door.
