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 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. The vehicle can have a maximum of four transmitters coded to it.

Battery Replacement

If the transmitter will not work within its normal range, change the battery.

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