actually she drove about 20km and nothing happened. I almost fell off my chair when BMW asist said they cannot start the vehicle remotely. But talking to another rep, if you leave the fob in the fob hole in the globe box, they can start it for you without the plastic key. but since we have both there was no point of them starting it.

atleast the third set (plastic key and fob) came in handy today.
thanks for all replies.
