This will eliminate any remaining electrical charge and allow the system to restart again.
It is essential to verify the size and quality of the battery prior to replacing it. The circuit board inside the key fob can be damaged in the event that the replacement battery is too large or has a different voltage. Before installing a new battery, you should clean the chip inside the fob in order to eliminate any harmful substances.
