This has nothing to do with lemon buyback, it sounds more like human error to me. First of all, there is no need to warm up any mordern day cars, especially for 15 minutes, but I wont go into that right now. If you are going to warm up the car, lock the door with the mechanical key so you will be sure that you have the key on you when entering the car. I had a 528i loaner a few months ago and I could drive that car without the key fob just like my 535i.
