4button VIPER (DEI) Keyfob Remote

This part is User-Programmable.  The control module in your vehicle must be programmed to accept the replacement part. Programming is a simple procedure. Instructions will be enclosed with the replacement part and Remotes Authority provides phone support to assist you if you have any questions. 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.
