[Guide] Changing CD Key & Retaining Profile

[Smaug]

This is the way how to change cd key without losing mpdata - that means you can use your profile with which you played on cracked servers once you buy original game.


1)Go to Start -> Run -> type in "regedit" adn hit enter
2)Navigate to HKEY_LOCAL_MACHINE/SOFTWARE/Activision/Call of Duty 4

4)Change the codkey value to your new cdkey - without dashes.

(Thanks to muiz for figuring out it is this easy)

I'm going to allow this since it works only for those who have bought the game.

For other members, please do not discuss or ask for cracked servers.

I only changed it in my register, and it worked fine.

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Activision\Call of Duty 4]
"codkey"="XXXXXXXXXXXXXXXXXXXXX"

xxx = your key

Did it? I will test it... it's quite possible that it's simple as that ... Thanks

3)In Hex editor select search (magnifying glass) and type in beginning of your old cdkey - or click on GoTo button and type in 723B64, it should find your cdkey splitted to two rows.

I hope this CDkey on your screen isn't the original CDkey that you bought with game......

No, it's from keygen, I am not that dumb ;)

[xyennefer]

Yeah, I thought so. Just wanted to make sure and 'wake you up' if that was mistake :)

There's a far easier way to change the key!

Load the game, and in options use the Change Key Code thingy on the right.

There, you can change the key and keep the stats. Easier, no? No need for TSearch and memory editing.

yeah and your stats reset

[muiz]

i only changed the reg, my stats did not reset

[Smaug]

Yeah, you are right, if you change it in reg it doesnt reset, if you change it in game menu they will. I'll edit the first post now.

well i did it this way and it worked.

i dl the rank 55 mpdate, started the game, changed the cdkey to razors, quit the game, copied the rank 55 mpdata in my profiles folder, started the game, changed the cdkey back my original one and played. had my rank 55

[Schumi2004]

WTF are you guys talking about!?
I change my CD-KEY from ingame options everyday and my stats NEVER reset.

Well, good for you. The stats are supposed to reset when you change CD-key as they are supposed to be bound to one CD-key. That's what developers say...
Now I wonder if the thing about reseting your stats when trying to change the mpdata file isn't bullshit too... ^^

Yeah but on the other side whenever I change cdkey I got my stats reset. Maybe it has something to do with generated/original keys? I used generated so far, I should have original game next week.

[Weedh3ad]

Well I changed mine many times, and never lost my stats.
Maybe I was lucky. I will not change it again incase this MAY reset my stats. Im not going to risk it.

[fakiato]

i tried it several times, but when i am connecting to a server he says the cd key is invalid...

i tried ZZZZZZZZZZZZZZZZZZZZ
and i tried to change 1 number of my original, but i says its invalid.. :(

any help?

[olgi]

Hmm... weird. I can change the key in game and never loose stats.

[fakiato]

ingame!? tought i only have to start call of duty....
but ingame is not possible, because the cdkey im using now is
already in use.

nobody knows an answer?

[olgi]

Well, if you use "keygenned" keys or make up stuff, then don't be surprised you can't connect to legit servers. That's what the "key in use" error is about.

[Weedout]

yeah I searched around and all the key changer instructions I found say you can only change key before gameplay not during.

[Meduza]

I bought my CoD 4 today, and when i changed cdkey in registry, and then started cod, MY STATS HAVE BEEN RESETED? i saved backup of my profiles before i changed the cdkey just in case, but everytime i replace it doesnt help, is there someone here that can help me? i dont want to lose my rank 40 :(

[BlackDove]

Yes, use Easy Account. It's at the top of this section and includes instructions.

i followed that instructions but i dont have any playerstats.txt and i dont want to cheat to rank 55

[BlackDove]

...A playerstats.txt file should be generated if you followed the instructions for Easy Transfer correctly.

Naah, it doesnt seem like that, i still have a copy of my mpdata and config file. what to do

[BlackDove]

It creates the playerstats.txt file in the same folder as Easy Account. This is stated in the directions...

If you're having questions about Easy Account, no need to post in this thread any more.

[server123]

Don't add it in the cod folder!!! use easy account/transfer

[Meduza]

Don't add it in the cod folder!!! use easy account/transfer
