yellowblue Battery Replacement Under normal use, the battery in your remote keyless entry transmitter should last about three 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. To replace your battery: 1. Insert a flat object like a dime into the slot on the back of the transmitter. Gently pry apart the front and back. 2. Gently pry the battery out of the transmitter. Do not use a metal object. 3. Put the new battery into the transmitter as shown on the transmitter (use type CR2032 battery or equivalent). 4. Put the two halves back together. Make sure the halves are together tightly so water won't get in. 5. Resynchronize and then test the transmitter. 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. 2-9
