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. Remove the old battery. 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 one three-volt, CR2032 battery, or equivalent type. 4. Snap the front and the back of the transmitter together. Make sure the cover is on tight, so water will not get inside the transmitter. 5. Test the operation of the transmitter with the vehicle. To replace the battery in the RKE transmitter, do the following: 1. Insert a flat object, with a thin edge, into the notch located below the panic alarm button, and separate the bottom half from the top half of the transmitter. 92
