they won't give just the chip, it's already inside the key when they buy them in.
it might be worthwhile getting an original key and barrel if you still have the other locks. You'd only need the one key then, and everything is back to normal.
failing that, a BMW replacement coded key will contain the correct chip.
you will often see cars with one old chipped one taped onto a replacement.
When you break open the replacement key, you'll see the chip
It'll probably look like one of the rectangles with a corner cut off in the pics above.
All you then need to do is get that chip next to the barrel before you turn the key.
Whether inside any key that works, taped to the side, etc, as long as it gets that chip to talk, it'll "unlock" the ECU.
