Matching Transmitter(s) to Your
Vehicle
Each RKE transmitter is coded to prevent another
transmitter from unlocking your vehicle. If a transmitter is
lost or stolen, a replacement can be purchased through
your dealer/retailer. All transmitters need to be re-coded
to match the new transmitter. The lost transmitter will no
longer work after the new transmitters are re-coded.
Each vehicle can have a maximum of four transmitters
matched to it.
