Since your vehicle is not onboard programmable, you will need a dealer or automotive locksmith to program the vehicle to accept the replacement remote. Please use an automotive locksmith rather than the dealer. You are likely to get a better service for a more reasonable price. An automotive locksmith will program your new remotes or keys by hooking up an expensive scan tool to your vehicle's computer and making the vehicle learn the new remotes or keys.
