CD key for HL2 (legit question)

[USFISTER]

Hey everybody. I'm deployed in Iraq (Ramadi) and I recently got a Dell XPS M170. I'd like to play my HL2 on it but I left all my CD keys back in Germany where I live. I thought I had copied them down to my external hard drive in a txt file, but I realized in Kuwait that the file was blank. Is there any way to buy CD keys from Sierra or a third party or anything. I don't want to buy the game again, I just want to play the copy I have. Thanks.

Load up the steam store and buy it again through that.

did you attach your cd key to the steam account before you went?
