The question can be interpreted in a few ways, so I will try to answer several possible questions:
Getting a compromised account back
You can get your WoW account back if it was taken over by someone else by filling in a form on the WoW website and proving the account is yours by means of your ID/Passport and/or the CD key of your original installation.
Getting a deactivated account back
If your account was shut down by yourself (ending payment) then you can simply go into your battle.net account administration page and start the subscription again to reactivate the account.
Getting a banned account back
If your account was permanently banned, nothing short of Blizzard's consent will start it up again. This means appealing to the ban using their contact form, and doing the best you can to prove that (if the case) you didn't do what you were banned for. Else, your account is simply locked.
Starting a new account with the old keys
Once the activation key has been used to make a WoW account, you cannot use it to create another. The created account is unique.
Installing WoW again
If you installed WoW once before and have an account, you no longer need the CD key to install the program. Simply installing it will allow you to log into your account. In fact, you can also log into your battle.net account and download the game from there.
The retail version of WoW does not include a game card, as you will get those starting days upon first activating the account using the product key that comes with the CDs. This would allow you to play and try out the game for some time before you'd have to spend additional money for it. With the download version, you also buy a product key, and creating your account using this key gets you your free starting days.
every one back in the old days
disadvantages of key account manager
The key account manager must ensure that the priority account is well maintained. Any issues with the account can jeopardize the business relationship.
the only way to get the key is to request a copy of it from your account on xploder or if you have not got an account you have to buy the key.

Try moving the wheel back and forth when turning the key. I've replaced ignitions on Neons before and not real uncommon for then to go bad.

You need to surender the key since you basically are giving back the room you rented during your stay. The Key is also a proof that you stay there/
The Live access key is a 16-digit code used to link the game to your Windows Live account. The key can usually be found on the back of your manual or on the inside of the DVD case.

The men of war CD key is located in the back of the game manual underneath the star if thats whats your asking. Its use is for you can create an online account and download the game.
