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 five transmitters coded to it.

Battery Replacement

Replace the battery if the Remote Control Battery check message appears in the DIC. See "Remote Control Battery Check" under DIC Warnings and Messages .

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

To replace the battery:

  1. Extend the key. See Keys for additional information.
