Check your owner's manual. You'll need the card with the permanent keyless entry code on it. It looks like a credit card in the owner manual folio. It's a pretty simple process; I just don't remember the exact steps. If you don't have your owner's manual go to http://www.genuineservice.com/genuineservice/en/default?page=Home to download the manual for your year vehicle. If you don't have the card with the permanent code you'll have to take your car to the dealership to get the code.
