If you're using Steam and have it working on one machine already, then you should only need to install the Steam client on your new computer then login with your existing account and it'll let you download and install CS. You won't need to use your key again.

What Javacat said. Just log in with your account and go to "my games". You should be able to download it from there. Also you can't use same account on 2 computers at the same time.
