if you bring the title with you in your name, or the last owners can do this if not been bought yet, show the dealer the vin they will cut you a new key with the proper vat ohm chip in the key. for any where from 30 to 75 bucks, depends on where you live in the country it seems.
normal a new key needs to be learned with the old key, but a 96 might not need this. 97 up does for sure.
