Battle field 3

Hi my name is William

I recently bought a copy of Battlefield 3, I Didn't do much research and thought that it would be like any other game I bought but when I got home I saw that you needed an Code to activate the Multiplayer option. Of course my copy didn't have one becouse its previous owner must have thrown it away or something. I was wondering if it might be possible for you to Create and new code for me?
