Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about four years. To replace the battery, do the following: 1. Insert a coin, or similar object, into the notch near the key ring. Turn it counterclockwise to separate the two halves of the transmitter. You can tell the battery is weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the battery. 2. Once the transmitter is separated, use a pencil eraser to remove the old battery. Do not use a metal object. 3. Replace the battery as the instructions under the cover indicate. Use a Duracella battery, type DL-2032, or a similar type. 4. Snap the transmitter back together tightly to be sure no moisture can enter. 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. 5. Check the operation of the transmitter. 2-9
