Harry Potter and the Deathly Hallow Part 1 2 code in 1 account

Hello guys!

I would like to report an issue with the reedeming code system in this game. I already had 1 copy of this game and i added to my EA game library succesfully. Thankfully I found another physical copy of the game and I wanted to check if the serial key is reedemed or not on the platform. Unfortunatelly your system not saying anything about it, and you can add 2 licence key to 1 account. I don't wanted that and this is not possible on other platforms. You can't add 2 licence key to your account on Steam etc, because what's the point of it? Can you guys remove the second licence key and it is possible that the second code going to be alive again? It's going to be a gift to my brother...

Thank you.
