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/retailer. 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 four transmitters programmed to it.

Battery Replacement

Replace the battery if the KEY FOB BATT LOW message displays in the DIC. See “KEY FOB BATT LOW” 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. 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 up.

Replace with a CR2032 or equivalent battery.
