Fortunately, this is not difficult to fix. Find something absorbent to place inside the fob. A tissue or paper towel would work well. Then, use a cotton swab that has been soaked in isopropyl alcohol and wipe down the circuit board as well as other components to eliminate any battery acid residue and contamination. Let the circuit board dry for some time in a warm and dry environment.

Replace the battery when the fob has dried out by replacing it with a new one with the same size and the same polarity ('+' (pointing upwards).
