A door lock assembly is configured for installation in a cross bore of a door. The lock assembly includes a lock housing including a disk portion having an outer perimeter and an inner wall extending from the disk portion and defining an annular space between the inner wall and the outer perimeter and a lock space inside of the inner wall. The inner wall is sized to fit within the cross bore and define an annular gap between the inner wall and the cross bore. A retention clip is removably attached to the lock housing and includes a retention portion that engages the cross bore to removably retain the lock housing within the cross bore without the use of fasteners.
