A parking meter has a vault housing and a vault door removably covering a main opening and having a back facing an interior of the housing. A lock assembly includes a lock cylinder disposed on the door and that has a body and a usually movable portion. A bolting mechanism operatively connects to the movable portion of the lock cylinder for selectively providing a locked position. A support structure is disposed on the interior side of the door and holds the bolting mechanism. A removable retainer engages the body of the lock cylinder, which is usually stationary. This results in the retainer preventing motion of the body sufficient to operate the bolting mechanism. The support structure is configured for releasably maintaining the retainer on the lock cylinder body. The vault housing defines a tool hole providing access to the interior of the housing for insertion of a disengagement tool through the tool hole. The retainer has a portion configured for connecting to the disengagement tool and is configured so that retracting the disengagement tool while connected to the retainer provides enough disengagement from the lock cylinder body to permit motion of the lock cylinder body to operate the bolting mechanism when the movable portion will not move relative to the body.
