Fortunately, this is not difficult to fix. Find something absorbent, and put it inside the fob - a paper towl or tissue can be used. Then you can use the cotton swab, dipped in isopropyl ethanol to wipe down the circuit board and other components to remove any residue of battery acid and contamination.
