Crysis warhead steam and cdkey

[gemcneill]

Ok so I download crysis warhead through steam and then I create my zip file and bam now I have an install, however when I go to start the server it asks for a cd key. So I download the game though steam to my computer and install crysis, thinking at some point a cd key will be given to me so I can enter it and make it work on my client. It never does, but the game starts just fine. How do I get this stupid key so this game will work. Any help here would be great.
