I removed the game from my account, before i purchased again, but nevertheless the key has not changed. :I

That's bad.
You should contact the Ubisoft support, tell the old fake key, so this gets invalidated and removed also from Steam.
And contact the Steam support for the same, so they update your game with the correct key.

Steam Support is definitely your best bet here.

I will try, but i guess nothing will happen by Ubisoft...
I already have a ticket there, with an another problem and it is still
unanswered for 2 weeks now. :I
I hope Steam can help.

But thanks for your support
