You can never use a key double ...no matter if you already have the base game and only missing the dlcs.

No, nothing you can do. The key can only be used once. It will add whatever you were missing from it to your account and that's it.

Got a question. I already had Killing Floor, but with no dlc, so I thought if I tried the key it would give me the dlc and then I'd be able to install the base game on my friends account. Well I used the key and I got all the dlc, but when I tried to install the base game on my friends account it said key was already used... I just got got jipped from a game. Anything I could do about this?
