Not all keys are the same. When I rebuilt my Nitro I took the stock locks off and contacted a company that sold those boat storage locks so I could get a complete set keyed alike. You could try the dealerships as sometimes they keep a lot of spare keys in the tool boxes. Look at the lock and see if it has a number imprinted on it. Personally though, after replacing the locks, I found them to be a PITA and if somebody wants in it, it would take less than 10 seconds to open it without a key.
