i don't know about the 1st gens but if you have a 2nd gen you will end up with two keys for your car. one to get in and one to start it. the tumblers in the door locks do not have the necessary tumblers to work in the ignition. if you want only one key you'll have to take the ignition as well as the door lock to a key smith/lock smith...one of those place that make keys from a lock.
