Then make use of the cotton swab, dipped in isopropyl ethanol to wipe down the circuit board and other components to get rid of any battery acid residue and contamination. Let the fob dry out for several days in a dry and warm environment.
Once the fob is dried out then replace the battery with a new one of the same size and the same polarity ('+' pointing upwards).

Radio Interference
When a key fob working correctly, it sends an audio frequency signal that is received by the receiver module in your car. If the signal is interrupted, your key fob will not work. This can be caused by objects or weather conditions, or other transmitters operating at the same frequency as your car.

You can reset your on-board computer if you disconnect the 12 volt batteries for about 15 minutes. This will remove any remaining electricity that could be causing problems. Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.
The internal chip in the key fob can also be damaged by water or dirt. If the key fob you purchased stopped working after being soaked, clean it with isopropyl, or an electronics cleaner. Then, you can reinstall the battery. If it is not working after exposure to soapy or salty water, the chip is probably damaged and must be replaced.

The fuse may be located in a variety of places, based on the type of vehicle. For instance it could be located under the rear seat or trunk, or the side of the dashboard.
