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 do this. Replace it with the new one. Use
type CR2032 or an equivalent. Make sure the
positive (+) side of the battery is facing down.
3. Snap the top and bottom together, making sure the
halves are together tightly so water won't get in.
4. Resynchronize and test the operation of the
transmitter with your vehicle.
