buying second hand bf2142, safe?

[unwashed potato!]

brother has got into bf2142 by using my game to play on his computer. he wants to give a go playing online with me but obviously we need another cd and anther account for this.

thinking of buying a second hand one online if it works out cheaper but concerned that he'd end up buying it but then it would say this cd key is registered else where so can't use that cd key.

so whats the deal with this? can we buy a second hand cd key and still use it? if so then as the game is already installed with my cd key is there any way to change the cd key without uninstalling the game?

cd key will be registered to someones EA account. So unless you get them to cough it up then no point really. Unless its a fresh copy where the CD Key isnt used

so is it possible to just buy the account then and use it for the current cd and then play together using just the one cd but having 2 accounts? if so where can i go to look for this as ebay is coming back with nothing

I bought one thinking you could make another account, you cant.
