### Matching Transmitter(s) to Your Vehicle

Each RKE transmitter is coded to prevent another transmitter from unlocking your 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. Each vehicle can have up to four transmitters matched 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 in the RKE transmitter:

1. Separate the halves of 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.
4. Put the transmitter back together tightly.
