My only salvation was the master key! And I say salvation, because I reside in East Africa and the BMW dealer here is the lamest ever.
Anyway, the fact that the spare key became inactive as well, makes me think that the mobilizer code changed altogether. Question is...can this be a DIY thing, or do I have to refer to the dealer?!

The small plastic key you're describing is the Emergency key. The vehicle has three types of keys:
- Master Key - This is the large key with the remote functions. Two of these were standard upon delivery of the vehicle.
- Valet Key - This is the gray key. One of these was standard upon delivery of the vehicle.
- Emergency Key - This is the small, black plastic key. One of these was standard upon delivery of the vehicle.
The key I just purchased was the master key and, as delivered from BMW (the only source for new keys), it was capable of starting/operating and manually locking/unlocking the vehicle. It was not programmed for remote locking/unlocking. This had to be performed at the vehicle.
To my knowledge there is no way for the end user to reconfigure the coding of the keys to prevent them from starting/operating the vehicle (other than destroying them). IMO either the key(s) are bad or there's a problem with the vehicle. I highly doubt your programming the master key to remote lock/unlock the vehicle is the cause of the problem.
