The dealership does not have to cut the key for you, all they have to do is provide you with the key code based off of the VIN#. From their a hardware store or locksmith with a neat little software program, can cut one based off of that code. When i used to work for a hardware store with a locksmith department, we used to charge about 15 bucks for this. Otherwise if you find the other half, its really easy to peice the two together and cut a new one (if you can find someone to attempt it) I know i used to do this all the time.
