Unfortunately, I do not think that there is a way to deactivate a game, so to speak. You could ask the seller for their Origin account details (which will have the code on it) and thereby take over their Origin account, however, if they are still using their Origin account for other games, you won't be able to do that.
You may get better success by contacting customer support directly. They might be able to help you with transferring the games. We are only users here like you.
