This will eliminate any remaining electrical charge and let the system start from scratch.
It is crucial to determine the size and type of the battery prior to replacing it. The circuit board in the fob's key can become damaged when the replacement battery is too large or has an unrelated voltage. You should also remove any corrosive materials from the chip in the fob before installing a new battery. The proper type of battery will ensure that the key fob is properly sealed and protected against moisture. Once the key fob is reinstalled, it should work normally.
