An apparatus for a cylindrical deadbolt assembly indicates whether the deadbolt is locked or unlocked. The apparatus comprises a trim piece, such as an escutcheon or collar, configured to be mounted on the inside face of a door, a dial mounted on an inside surface of the trim piece, and a cam. The trim piece comprises one or more windows for displaying information from the dial. The dial is operative to travel between first and second positions to provide a first indication when the deadbolt is locked and a second indication when the deadbolt is unlocked. The cylinder tail piece turns the cam to move the dial between its first and second positions.
