I know this is an older post but I just bought my 2nd copy on 7/25/2011 of the game brand new and I found yet again no CD key for Crysis wars.

So I came looking here for a possible solution, but while looking I a may have found a solution to share.

Long story short...

My first new copy I bought at Fry's electronics and not gamestop, and I thought{ just like another fellow here} I somehow lost the pamphlet that had the CD key.

Turns out There is no CD key other than the one with Crysis warhead! If your having problems playing it. I suggest trying what I did.

I am guessing you need to have warhead installed and patched with 1.1 before you try to install the Crysis wars. Then patch Crysis wars with the "Crysis Warhead-Crysis wars patch 2" {thats the real name of the patch} and also Crysis wars patch 1.5. Enter your Crysis Warhead CD key when asked to do so,and it should work, or at leastit did for me.

If that doesnt work and you still need a CD key for Crysis Wars and you can verify some simple info with EA games.

They will give you a new key to activate Crysis wars! How do I know this you may ask? They gave me one after I told them my dilemma since they are aware of this issue.

I guess now I can sell my first copy since I finally have a fully functional Crysis Maximum Edition game.
