That would make total sense. CR2032 batteries are known to have a short shelf life. BMW has been using that size for years so who knows if a old batch of batteries that have been sitting around was used?
I like to change mine every year regardless on my last Jeep Fob. The Jeep Summit would give similar “no key in vehicle” message if the battery wasn’t fresh in key fob.
UPDATE: I just changed my BMW fob battery since I have no idea how old the factory installed battery was. Factory had a CR2030 Panasonic brand battery. I keep a good supply of fresh Energizer 2032 batteries around just for this. I noticed a nice white thick seal inside the key fob to keep out moisture.
