Matching Transmitter(s) to Your Vehicle

Each RKE transmitter is uniquely coded to prevent another transmitter from unlocking the vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your retailer. Remember to bring any additional transmitters so they can also be re-coded to match the new transmitter. Once your retailer has coded the new transmitter, the lost transmitter cannot unlock the vehicle. The vehicle can have a maximum of four transmitters coded to it.

Battery Replacement

Under normal use, the battery in the RKE transmitter should last about four years.

If the battery is weak the transmitter will not work within its normal range. It is probably time to change the battery if you have to be very close to the vehicle before the transmitter works.

Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.
