Battery Replacement Under normal use, the battery in your keyless access transmitter should last about three years. You can tell the battery is weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the battery. A weak battery may also cause the DIC to display NO FOBS DETECTED when you try to start the vehicle. If this happens, place the transmitter in the glove box transmitter pocket with the buttons facing to the right. Then, with the vehicle in PARK (P) or NEUTRAL (N), press the brake pedal and the START button. Although this will start the vehicle, it is recommended that you replace the transmitter battery as soon as possible. The DIC may display FOB BATTERY LOW. 1. Insert a coin or similar object into the slot on the back of the transmitter and gently pry apart the front and back. 2. Gently pull the battery out of the transmitter. 3. Put the new battery in the transmitter, positive (+) side up. Use a battery, type CR2032, or equivalent. 4. Reassemble the transmitter. Make sure to put it together so water won't get in. 5. Test the transmitter. 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. 2-7
