if you got the game thru steam then go thru steam. activision will have nothing to do with that. i know there are threads probablly 100s or so down that ppl were having this issue as well. they had to do something to get the cd key as it did not come with it. they had to go to a file or location or something.

here is something i found on like page 11 or so.


If it asks for a key, the CD Key is stored in the registry. To view it, do the following steps:

•Press Win+R.
•Type "regedit".
•Navigate to "HKEY_Local_Machine".
•Go to "Software".
•Go to "Wow6432Node"
•Navigate to "Activision".
•Click on "Call of Duty 4".
•The key should be stored under the entry "codkey".

If you can't find it, try to update PunkBuster for CoD4, start the game and then do the same steps as stated above.

If you can't find the key at all, you most likely will need to re-install the game, as that would make a new entry in the registry.

Valve didn't make CoD, so you would go through Activision.

Basically reinstalling, either way have a try OP.

no but valve is the one messing up the cd key thing. they are the ones who you are getting a key code from. go thru activision and they are just going to tell you to go to the place you bought the game from.

the method i described is not basically reinstalling. that is only if you still dont find the key code. and that was the last option to try. prior to it, it suggest to update punkbuster which you must do manually. i know many steam users having issues with punkbuster. steam downloads punkbuster for you but not with latest update.

This system what cad80 writed to me dosnet work, i think because i have reinstalled my windows before re-download the CoD from steam. I already made an ticket in steam support, i hope they can help me out of this trouble.
cad80_99 Sep 7, 2013 @ 7:17am 
did you reinstall the game after you had reinstalled your windows? if not give that a try. as what i posted was from another post and from someone else. but if that does not show your cd key, then it says to manually update punkbuster which you do from there site. and if that still does not work then delete the game and reinstall it. and after you reinstall the game then update punkbuster manually

Thank you for contacting Steam Support.

If you are having difficulty accessing the multiplayer portion of the game due to a key error, please take the follwing steps:

-If you are running in Windows Vista or Windows 7, please completely exit Steam, and right-click on the shortcut which you use to launch Steam and select "Run as Administrator."

-If you are running in Windows XP, take the following steps:
1) Exit Steam.
2) Go to the "Start" menu, select "Run", type "regedit" and click "OK".
3) Navigate to the following registry key: HKEY_CURRENT_USER\SOFTWARE\VALVE
4) Right click and select "Permissions"
5) Check the boxes for "Admin" and "System" to "Full control" and "Read".

First, verify the GCF Cache for the game:
Title: Verifying GCF Cache Files
Link: http://support.steampowered.com/kb_article.php?ref=2037-QEUH-3335

Verifying the GCF Cache solves most CD Key issues for most users.

NOTE: The CD Key for this title is not shown to the user in Steam.


If it still does not work, please try deleting your Call of Duty 4 registry entry:

Go to the "Start" menu, select "Run", type "regedit" and click "OK".

If you are using a 32-bit version of Windows, navigate to the following registry key: HKEY_LOCAL_MACHINE\SOFTWARE\Activision\Call of Duty 4
Note: In 64-bit operating systems, this path may begin as: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Activision\Call of Duty 4

The contents of the registry entry "codkey" is your CD Key. Please write this key down for future reference.

Right-click on the entry "codkey" and select "Delete".

Exit regedit.

Restart your computer.



Log in to your Steam account using the following instructions:

-If you are running in Windows Vista or Windows 7, right-click on the shortcut which you use to launch Steam and select "Run as Administrator."

-If you are running in Windows XP, ensure the the following steps have been taken before starting Steam:
1) Exit Steam.
2) Go to the "Start" menu, select "Run", type "regedit" and click "OK".
3) Navigate to the following registry key: HKEY_CURRENT_USER\SOFTWARE\VALVE
4) Right click and select "Permissions"
5) Check the boxes for "Admin" and "System" to "Full control" and "Read".


From the Library list, right-click on "Call of Duty 4" and select "Properties" from the menu.

Select the "Local files" tab and click the "Verify integrity of game cache..." button.

Steam will verify the game cache files (GCF's) - this process may take several minutes.

Once the process is completed, the "Check" window will automatically exit and you should be able to launch your game.

You may also try using the key previously found in your registry if COD4 asks for a CD Key again.


If you continue to have difficulty, further technical support for this title is handled by a third party support department - please follow the link below for instructions to contact the support provider for this title:
