Car: 2013 328i Luxury Line with Premium Package that includes Comfort Access. (all that info may be redundant but included nonetheless)

Issue: Key fob battery "appears" to be weak. I frequently have to be right next to the car to get it to work. (car built May 15, 2013)

Question: If the battery actually does need replacing, is it straight-forward swap or does it need to be re-programmed to "match" the car?

I "think" it's straight-forward swap but you guys are SO on top of these things I thought I'd ask you.

Thanks in advance!

Simply swap in a new CR2450. Takes but a minute.

I had a different issue-- my proximity lock on the driver side would only work intermittently when the key was in my pocket with my leg PRESSED AGAINST the car. A replacement door handle solved the issue but only after the dealer replaced the fob battery to "fix" it, despite me telling them I had already done so.
