Vehicle lock assembly including a mounting bracket

A vehicle lock assembly including a cylinder lock and a mounting bracket which is adapted to mount the cylinder lock on a vehicle structure associated with a deck lid of a vehicle. The mounting bracket includes a mounting lug adapted to be fastened to the vehicle structure and mounting arms which support the cylinder lock rearwardly of the exterior panel. The lock mounting arms define mounting surfaces which cooperate with indexing portions on the lock housing to substantially prevent rotation of the cylinder lock relative to the mounting bracket and the deck lid. In one embodiment, the lock housing is mounted on the mounting bracket in dovetail fashion to prevent the mounting arms from spreading apart if an attempt is made to forcibly rotate the cylinder lock.
