Battery Replacement Under normal use, the battery in the remote keyless entry transmitter should last about four years. You can tell the battery is weak if the transmitter will not work, at the normal range, in any location. If you have to get close to your vehicle before the transmitter works, it is probably time to change the battery. The KEY FOB BATT LOW message in the vehicle's DIC will display, if the remote keyless entry transmitter battery is low. Notice: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. To replace the battery do the following: 1. Insert a flat object with a thin edge into the notch, located below the Vehicle Locator/Panic Alarm button, and pry the front and back apart. 2. Remove the old battery, but do not use a metal object to do this. 3. Slide the new battery into the transmitter with the positive side of the battery facing up. Use a type CR2032 battery, or equivalent type. 4. Snap the front and the back of the transmitter together. 5. Test the operation of the transmitter with the vehicle. 2-6
