ABSTRACT:
An apparatus for preventing a deadbolt lock from being opened from the outside of a door with a key. The base is constructed from resilient material, the base defining at least one aperture for receiving one of a plurality of types of finger actuator in one of a plurality of orientations, the aperture shaped to prevent a finger actuator inserted therein from rotating relative to the base. A U-shaped plate is coupled to the base and is moveable between an extended position wherein the U-shaped plate is engageable with a member extending outwardly from the door and a storage position wherein the U-shaped plate is adjacent to the base. When a finger actuator is in the locked position and inserted into the aperture, and when the U-shaped plate is engaged with the member extending outwardly from the door, the finger actuator is prevented from moving into the unlocked position.
