Matching Transmitter(s) to Your Vehicle

Each RKE transmitter is 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 no longer works after the new transmitters are re-coded. The vehicle can have a maximum of eight transmitters matched to it. See "Relearn Remote Key" under DIC Operation and Displays .

Battery Replacement

Replace the battery if the Replace Battery In Remote Key message displays in the DIC. See "Replace Battery In Remote Key" under DIC Warnings and Messages for additional information.

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