It also speeds up the process of rust and corrosion.

Luckily, this is a simple issue to fix. Find something absorbent to put inside the fob. A tissue or a paper towel will work. Then you can use a cotton swab dipped in isopropyl ethanol to wipe down the circuit board and other components to get rid of any residues of acid from batteries and contamination.

This will flush out any residual electrical energy that could be causing problems. Begin by removing your cable from the negative terminal of the battery first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.

The internal chip in the key fob can be damaged by water or dirt. If your key quit working after it got wet, you need to clean the electronic component using isopropyl alcohol or an electronic cleaner prior to reinstalling the battery. If your key has stopped working after being exposed to soapy or salted water, it's likely that the chip is fried and needs to be replaced.
