Replacing the battery
The remote transmitter is powered by one coin type three-volt lithium
battery CR2032 or equivalent. Typical operating range will allow you to
be up to 10 meters (33 feet) away from your vehicle. A decrease in
operating range can be caused by:
²weather conditions
²nearby radio towers
²structures around the vehicle
²other vehicles parked next to the vehicle
To replace the battery:
1. Twist a thin coin between the two
halves of the transmitter near the
key ring. DO NOT TAKE THE
FRONT PART OF THE
TRANSMITTER APART.
2. Place the positive (+) side of new
battery in the same orientation.
