No. Only one . It was beat up when given to me. It had electrical tape. I just now cut it open and took a peek inside. It wasn't glued, only taped The battery slide out with ease. I have never been in this key fob and it looks like this battery has 2 small connectors that need to be soldered on. I was able to slide the battery out.
I just ordered a new battery from amazon and will try it tomorrow when it arrives. Will a dead battery / bad connection not soldered battery not work? I have minimal experience with BMW but I thought the battery only controlled the door locks and if battery is dead it will still start.
Thanks
