Finding Your Lost Call of Duty CD Key

The main site administrator for our gaming team recently had a problem with his Call of Duty 4 CD Key: He couldn’t find it. There is a very simple solution for those running Windows operating systems and playing COD4 to find your CD Key.

Click on “Start” then “Run”
In the “Open” field enter “Regedit” and click on “OK”

Windows Registry Editor will open.

Expand in this order: “My Computer”, “HKEY_LOCAL_MACHINE”, “SOFTWARE”, “Activision”, and finally select “Call of Duty 4″

In the right pane you will see “codkey”. Easy enough huh?

Oh yeah, you can backup this CD key as well just in case you lose your CD case with the key AND somehow the registry gets rolled back to a previous time or gets deleted.
Right click on the “Call of Duty 4″ folder or “codkey” and select “Export”. Save this file in a safe place. If you ever need it again you can double click on the exported key and it will be imported right back into your registry.

  3. no tips on how to do this on vista?

  4. I don’t use Vista so I can’t poke in the registry to look for it. If I can get my hands on a Vista PC then I’ll install COD on it and play around.

  5. WORKED FOR ME ON VISTA. followed instructions to a T and it worked just fine. I first saved the regedit in documents and then i opened it up in wordpad and saved it again as .txt document and just highlighted the cd key. Just ctrl+F and search “codkey” in the document and the code in that line is the cd key.

    I have COD WAW does anyone know how many discs it has 1 or 2 when you buy it, I only have the DVD that you need to run the game while you play, is there another DVD or just the 1,

    If I can just get the key from the registry then I can just re-install rather then copying the whole game to my external hard drive,

    Please help
