If you no anybody around you with keys try one of theirs. We always keep all keys 'cause there aren't many combos. With worn keys and locks, you can usaully find a key that will work, then duplicate it. Maybe the junk yard guy has a stash.
Best way to go I use to keep a copy of every old mopar key I could had about 15 and never found a 74 to 60 car I couldn't start right up so call a yard and see if they will give you some
