Battery Replacement Under normal use, the battery in your 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's 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 in the remote keyless entry transmitter do the following: 1. Use a flat thin object to separate the bottom half from the top half of the transmitter. 2. Remove the battery and replace it with the new one. Make sure the positive side of the battery faces up. Use one three-volt, CR2032, or equivalent, type battery. 3. Put the two halves back together. Make sure the cover is on tightly, so water will not get in. 2-7
