I had my first issue this evening with my 2019 320d M-Sport.

The car had probably been sat on the drive untouched for 30 hours or so. When I tried to unlock it with my main key, I got no response. So I tried the second key; exactly the same. None of the buttons seemed to provoke any response, although being dark I did notice looking through the window that the hazard warning button was lit, along with the engine-start and parking brake buttons.

I was curious if it would respond to the iPhone app. I tried the headlight flash - worked fine. After that I tried unlocking the car from the app and I was in. The engine started fine as well. After that point my key was also working again.

I haven't found anything similar on the forum - just people who got in ok, but their key wasn't detected to start the engine.

Does anyone out there have any clues what this might be? Good job I had the app connected and set up! I'll make a phone call in the morning to the dealership.
