That doesn't even seem possible...
I wonder if you use a pair of pliers to hold the metal part - will it still start the car? I'm betting it won't. Perhaps this fob has the immobiliser chip (EWS) buried somewhere in it that you haven't spotted. They can be small - like a grain of rice - although the BMW keys usually have a circuit board containing the remote lock/unlock transmitter as well as the immobiliser chip (EWS).
A regular BMW key has all this... (the EWS parts are G, H and L)
Other makers (like VW for instance) use a small immobiliser chip like this...
The only other possibility is that the entire immobiliser (EWS) system in your car has been disabled somehow. I'm not even sure if this is possible and it's certainly not desirable!
