Shinobi Posted January 22, 2013 Share Posted January 22, 2013 (edited) 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. This tutorial is based off of my own troubles and I made steps I took which fixed my problem and is available for other players to see Edited March 31, 2018 by Fearless Staff 1 Quote Link to comment Share on other sites More sharing options...
