A key FOB battery may last 3 years or so, but eventually it needs to be replaced. Also, it is a good idea to read the manual and learn how to unlock and start the vehicle when the key FOB battery fails.

I probably should replace mine. I bought my car new in 2010, and haven't ever changed the battery on either key that came with it.
