Ours seems to be a bit longer but I can't say exactly how many months.

EDIT: This is not quite correct. See the post below for better information.

I suspect the key fobs are constantly sending out a signal whether they are near the car or not. When you think about it, how would they know if they were close? They don't have GPS and they don't have a way to sense that the vehicle is near. The only way they can work is to constantly broadcast. The car is constantly listening and reacts when the fob comes close enough.
