The problem is when the circuit board inside the fob is in contact with water. It creates a fantastic conductor, and it shorts out the components. It also accelerates corrosion and rust.
This is an easy fix. Find something absorbent to place inside the fob. A tissue or paper towel would be ideal. Then apply a cotton swab dipped in isopropyl alcohol to wipe down the circuit board as well as other components to eliminate any residues of acid from batteries and contamination. Allow the circuit board to air dry in a dry, warm environment for a few weeks.
After the fob has dried out and the battery is replaced with an alternative of the same size and the same polarity ('+' directed upwards).

After 15 minutes, reconnect the battery in reverse order: positive first, negative second.
The internal chip inside the key fob may be damaged by water or dirt. If your key has stopped working after being wet, you need to clean the electronic component using isopropyl alcohol or an electronic cleaner prior to reinstalling the battery. If the key stops working after exposure to soapy or salted water, it is likely that the chip has been damaged and needs to be replaced.
