[Shinobi]

IMPORTANT: This tutorial is for users that have a pirated multiplayer key code and want to switch to another key or STEAM pre-keycode purchase***

 

1: If you have installed the game, and the system has your pirated key as default, you will need to uninstall the game.

 

2: After uninstalling the game, run regedit by clicking start button and searching "regedit" in your search bar. (click it)

 

3:In regedit, go through each tab (FILE/VIEW/EDIT ETC..) until you find search registry and search "CoDkeycode"

 

4: After search, the system will show you a file that shows your current key code. If it isnt the key code you want, right click the file and delete it from your system,

 

5: Go back through your file system and re-install Call of Duty 4

 

6: Go into the multiplayer version and access the "multiplayer options menu"

 

7: Click 'Key Code' option and find a pre-entered new key (STEAM PURCHASED GAME ONLY) or type in the new key you want.

 

8: Join a server and see if your new key code works.
