Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about two years. 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. 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. To replace the battery in the remote keyless entry transmitter, do the following: 1. Carefully pry off the cover by inserting a coin (or similar object) in the slot between the covers and twist. 2. Lift off the back cover. 3. Remove and replace the battery. Use one battery, type CR2032, or a similar type. Put the new battery in printed side down. 4. Put the back cover on. Make sure the cover is on tight so water won't get in. 5. Check the transmitter operation. If the transmitter does not work after battery replacement, it may need to be resynchronized or matched to your vehicle. See "Resynchronization" following. 2-12
