When the fob has dried out then replace the battery with a new one of the same size and the same polarity ('+' that is pointing upwards). It isn't easy to open the fob in order to access the battery, but if have a small flat-head screwdriver handy it should slide in easily. After the fob has been reassembled and working, it should operate like normal. If it doesn't work you may need to program it again or replace the module.

You can reset the on-board computer by disconnecting the 12 Volt batteries for 15 minutes. This will flush out any residual power that may be causing issues. Remove the cable first from the negative terminal, then from the positive terminal. After 15 minutes, reconnect the battery in reverse order: positive first, negative second.
Dirt or water can cause damage to the internal chip of the key fob. If your key's function stopped after being wet, you need to clean the electronic component with isopropyl Alcohol or an electronic cleaner prior to reinstalling the battery.
