Test the operation of the transmitter with your vehicle. If the transmitter does not work, resynchronize the transmitter. Resynchronization Pressing the transmitter buttons numerous times (approximately 250 times) out of the vehicle's operating range may cause the transmitter not to work. Replacing the battery and pressing the transmitter buttons out of range will also cause the transmitter not to work. If only the instant alarm works, the transmitter needs to be resynchronized to the receiver. Resynchronize by pressing and holding both the buttons with the lock and unlock symbols at the same time for about eight seconds. You must be within range of the vehicle. Once the transmitter has been resynchronized, the locks will cycle (the horn may chirp and the exterior lamps may flash) depending on the security feedback settings. The system should now operate properly. For battery replacement, use one DuracellR battery, type DL-2032, or a similar type. To replace the battery: 1. Insert a coin into the notch near the key ring. Turn the coin counterclockwise to separate the two halves of the transmitter. 2. Once the transmitter is separated, use a pencil eraser to remove the old battery. Do not use a metal object. 2-13
