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.

Battery Replacement

The battery is weak if the LED light fails to illuminate or if the transmitter will not work at the normal operating range. If you have to get close to your vehicle before the transmitter works, 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.
