Battery Replacement Under normal use, the battery in the RKE transmitter should last about four years. If the battery is weak the transmitter will not work within its normal range. It is probably time to change the battery if you have to be very close to the vehicle before the transmitter works. 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 trunk release 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
