Resynchronization This is used to keep the transmitter of the vehicle communicating with the receiver of the vehicle. Resynchronization may be required due to the security method used by this system. Your vehicle has an automatic resynchronization function built into the system. If your transmitter is not working properly and you have to manually resynchronize, press the lock and unlock buttons at the same time for seven seconds while you are near your vehicle. The doors will lock or unlock, depending on their starting position. If they do not, contact your retailer for service. 2. Once the transmitter is separated, use a pencil or similar object to remove the old battery. Do not use a metal object. 3. Insert the new battery as the instructions under the cover indicate. 4. Snap the transmitter back together tightly to be sure no moisture can enter. 5. Check the operation of the transmitter. If the transmitter does not work, try synchronizing your transmitter with your receiver. See "Resynchronization" for more information. 2-8
