Positive first, then negative, and finally negative.

Dirt or water can harm the internal chip of the key fob. If your key fob stopped working after being wet, wash it with isopropyl, or an electronics cleaner. After that, replace the battery. If it is not working after exposure to salty or soapy water, the chip is probably damaged and should be replaced.
