If you have to get close to your vehicle before the transmitter works, it's probablytime to change the battery. NOTICE: When replacing the battery, use care not touch to any of the circuitry. Static from your body transferred to these surfaces may damage the transmitter. To replace the battery in theKeyless Entry System: 1. Use a small coin or flathead screwdriver to separate the bottom halffrom the top half of the transmitter. 2.
