Locks and Security Replacing the battery The transmitter is powered by one coin type three-volt lithium battery. 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 up. Refer to the diagram inside the transmitter unit. 3. Snap the two halves back together. Replacing lost transmitters • Take all your vehicle's transmitters to your dealer if service is required. • If you purchase additional transmitters (up to four may be programmed into memory), perform the following procedure. With all doors closed and locked, insert and remove the key from the ignition six times within ten seconds. The park lamps will flash twice to confirm the programming mode has been entered. 111
