could disassemble the door-interior and remove the cylinder and take it to a locksmith and have it repaired, but it's probably easier to get a new cylinder if available from the dealership or a used one from the junkyard. I have gotten locks from the junkyard when the key has been left in the ignition which the junkyard often times do. People who don't have a wonderful car like ours get jealous and vandalize it. It's happened with my Z-cars many times. GRRRRR!!!!
