if you have both parts, some places can still copy it. idk where, but i know some can. otherwise, your going to have to spend some money. you'll have to either tow the car, or have them come to you.

your gonna have to show proof of ownership blah blah, and they'll be able to make you a key. i forget how exactly they do it, i believe by making a mold of your lock.

Or you can find any 240 key, and they'll re-key your locks, and i THINK they can do the ignition too.
