A locking mechanism for a door includes an outside actuator, an inside actuator, and a housing removably fixed to the door. A locking bar is selectively engageable with the housing. A first cam member is operable to move the locking bar from an unlocked position wherein the locking bar is released from the housing and a locked position wherein the locking bar is fixedly coupled to the housing. A spindle is rotatably coupled to the inside actuator and selectively coupled to the outside actuator. A second cam member is coupled to the first cam member and to the spindle and operable to move the locking bar from the locked position to the unlocked position in response to rotation of the inside actuator from a neutral position to one of a first clockwise position and a second counterclockwise position.
