This is a simple fix. Find something absorbent to place inside the fob. A tissue or a paper towel will be a good choice. Then make use of an alcohol-soaked cotton swab and a cotton swab isopropyl ethanol to wipe down the circuit board and other components to get rid of any residues of acid from batteries and contamination.
