The control module in your vehicle must be programmed to accept the replacement part. Instructions will be enclosed with the replacement part. Programming does require that your system have a working valet button or switch. It is also very helpful (though not essential) that your alarm system have a working siren. Please note not all customers will be able to complete the programming on their own. If you are having trouble or unsure, diagnostic programming is available at your local qualified automotive locksmith or alarm installation shop.
