Nope. The boards in them are different; the board from your black plastic key will not fit in the chrome shell.
If you are good at detail PC chip soldering, you can buy a USED chrome key and swap the "heart" chip, but it's not for the weak of heart (there's a current thread with links/details in the W210 forum). Or you can send your black key to drkknight (see his thread in FSTW) and for $120 or so he'll do the conversion, returning you a new chrome key with the chip transplanted from yours.
