Looking for help with my 335is key fob issues as well. I bought the car back in 2016 and the CA worked flawlessly for several years (i.e. while it was under warranty!). About two years ago, the lock feature on the drivers door started acting up. Sometimes it would work just fine and other times I would have to tap the ridges several times to get it to lock. Annoying, but still functional.

Flash forward to today. I just got my car back after an extended body shop visit. My main key doesn’t work on the drivers handle, the trunk, or to start the car. It still works fine to lock/unlock the passenger handle. My backup key will start the car, open the trunk, passenger door lock/unlock, but drivers door only locks sometimes, and doesn’t unlock at all. WTF?

Any ideas where to start with two key fobs that behave differently and not consistently?

Would prefer not to take to a dealer, but as wonky as the issue seems to be, they might be best equipped to figure out something so weird?

Thanks!
