Fortunately, this is not difficult to fix. Simply locate something absorbent and place it inside the fob - a paper towl or tissue can be used. Use a cotton swab with isopropyl to clean the circuit board as well as any other components. Allow the circuit board to air dry in a warm, dry environment for a few weeks.
