Programming Transmitters to the Vehicle Only RKE transmitters programmed to the vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer. When the replacement transmitter is programmed to the vehicle, all remaining transmitters must also be programmed. Any lost or stolen transmitters no longer work once the new transmitter is programmed. Each vehicle can have up to eight transmitters programmed to it. See your dealer for programming new transmitters. Battery Replacement Replace the battery if the REPLACE BATTERY IN REMOTE KEY message appears in the DIC. See "REPLACE BATTERY IN REMOTE KEY" under DIC Warnings and Messages on page 4 ‑ 49 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. To replace the battery: 1. Separate the transmitter with a flat, thin object, such as a flat head screwdriver. . Carefully insert the tool into the notch located along the parting line of the transmitter. Do not insert the tool too far. Stop as soon as resistance is felt. Twist the tool until the transmitter is separated. . 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. 3-6
