First thats cd-key. Nobody will give it ya so dont disturb. Buy HL and you will have it. Its not expensive.

I have a the cd-key but it says tha is already used do you know where can i find more cd-keys but not buying the game

Peh. You are unlucky and if it says to you then, if you bought the game should send them and they will return right cd-key and if you download it then you cant play.

No we can not, you have to buy the game or look on your own, you won't get help with warez here, just buy the game.
