Is it possible to tie a w205 facelift key to my w204 fl C63?

I have this extra key from my 2019 C43 that I was wondering if I could have it set to work for my w204 C63. My w204 has all the keyless features so is it possible the newer keys can be linked to it?

straight up no way. Even if it is, you wouldn't want to pay and people smart enough to do it would easily require a donor facelift car or around 10k to make it happen.

"I have a extra key for the a 2019 C43 I sold (and did not give to the Buyer)" - and I am in Germany - well.... frankly that Key you kept can't be re-programmed for anything other that the C43 it was programmed to.

Oh... in case it has been unclear - your W204 has the "old key fob type" and the 2019 has the "new key fob type" - and each are keys for a entirely different system from each other..

Oh, glad you know the actual situation based on assumptions.
