Battery Replacement Under normal use, the battery in your RKE transmitter should last about four years. 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. 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 RKE transmitter, do the following: 1. Use a flat thin object to pry open the transmitter. 2. Once the transmitter is separated, use a pencil or similar object to remove the old battery. Do not use a metal object. 3. Slide the new battery into the transmitter with the positive side of the battery facing down. Use a type CR2032 battery, or equivalent type. 4. Snap the transmitter back together tightly to be sure no moisture can enter. 5. Check the operation of the transmitter. 100
