Programming Transmitters to the Vehicle Only RKE transmitters programmed to this vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer/retailer. When the replacement transmitter is programmed to this vehicle, all remaining transmitters must also be reprogrammed. Any lost or stolen transmitters will no longer work once the new transmitter is programmed. Each vehicle can have up to eight transmitters programmed to it. See "Relearn Remote Key" under DIC Operation and Displays (With DIC Buttons) on page 4‑43 or DIC Operation and Displays (Without DIC Buttons) on page 4‑51 for instructions on how to match RKE transmitters to your vehicle. To replace the battery: 1. Separate the transmitter with a flat, thin object inserted into the notch on the side. 2. Remove the old battery. Do not use a metal object. 3. Insert the new battery, positive side facing down. Replace with a CR2032 or equivalent battery. 4. Snap the transmitter back together. 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 on page 4‑57 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. 3-6
