Key fob battery

Yes and I have had multiple warnings. I was able to get by for a few weeks the first time and only waited several days the second. I think my fob doesn’t get to remain in sleep mode because it is sitting on a hook next to the keys and second set of keys for four other vehicles and my wife and children rattle it whenever they grab their keys. Guess I will either move my keys or keep replacing the battery!

Hmmm, how come the low battery notification work for everyone else, in my experience the battery simply dies before the car even prompts the battery on the key fob is low.
I wonder at what voltage the button battery is at is when the low battery message triggers? Any clue?

I tried buying from different sources and different batteries, it still does it I guess I might be buying old stock all along. Not sure what else to try. Or maybe I need to spray some contact cleaner on the key fob contacts, something like that.
