Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry 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. Remember to bring
any remaining transmitters with you when you go to
your dealer. When the dealer matches the replacement
transmitter to your vehicle, any remaining transmitters
must also be matched. Once your dealer has coded the
new transmitter, the lost transmitter will not unlock
your vehicle. Each vehicle can have a maximum of four
transmitters matched to it.
