Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about fouryears. You can tell the battery is weak if the transmitter won't work at the normal range in location. If you have to any get closeto your vehicle before the transmitter works, it's probably time to change thebattery. To replace thebattery: 1. Insert a coin into the notch near the keyring. Turn the coin counterclockwiseto separate thetwo halves of the transmitter. 2. Once the transmitter is separated, use a pencil to remove the old battery. Do not use a metalobject. 3. Remove and replace thebattery as the instructions under the cover indicate. 4. Snap thetransmitter back together tightly to be sure no moisture can enter. 5. Resynchronize thetransmitter by pressing and holding the LOCK and UNLOCK buttons for about eight seconds within range of the vehicle. Once the transmitter is resynchronized, the horn will c h q and the exterior lamps will flash once. NOTICE: When replacing the battery, use care not to touch any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. For battery replacement, use a Duracella battery, type DL-2032, or asimilar type. 2-13
