Programming Transmitters to the Vehicle

Only keyless access transmitters programmed to the vehicle will work.

If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer.

The vehicle can be reprogrammed so that lost or stolen transmitters no longer work. Each vehicle can have up to four transmitters matched to it.
