Locks and Security Replacing the battery The transmitter is powered by one coin type threeĆvolt 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: • weather conditions • nearby radio towers • structures around the vehicle • other 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 will not cause the remote transmitter to become deprogrammed from your vehicle. The remote transmitter should operate normally after battery replacement. 119
