Definitely unusual to have expended keyfob battery at only 2600 miles, but it’s not impossible.

Happened to me with our Audi Q7’s keyfob. I had to replace it after only 2 months since taking delivery. Shortly after, I discovered the culprit. Our then 2yo daughter would get her hands on it occasionally and press it endlessly. Car would not respond because it’s parked too far away 50 stories below in the garage, but we figured this would happen several times a week and after 2 months of this the battery got used up. Also, consider other possible ways of repeated inadvertent keyfob button pressing; like in your pocket, purse, gym bag, etc. I admit that in the past, I’ve even caught myself pressing repeatedly on key fobs while they’re in my pocket on occasion, possibly as some form of habitual fidgeting or self-soothing, as if it was some kind of stress ball lol.
