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.
Refer to the diagram inside the
transmitter unit.
3. Snap the two halves back
together.
Replacement of the battery willnotcause the remote transmitter to
become deprogrammed from your vehicle. The remote transmitter should
operate normally after battery replacement.
