Before replacing the battery, it's important to make sure it is the correct type and size. If the replacement battery is too small or has different voltage, it can damage the circuit board within the key fob. It is also recommended to clean any corrosive materials off the chip in the fob prior to installing the new battery. The correct type of battery can ensure that the key fob is properly sealed and protected from moisture. Once the key fob is reinstalled, it should work normal.
