renewing promo code for BF3

Promo codes and game keys are two seperate entities.  A promo code is like the E3 close quarters code that was a limited time code that got you a discount or free item.  The game codes that you received from the humble bundle are not limited times, and if they are not working you must speak with a game advisor who can check the codes and add them to your Origin account.  You can contact a game advisor here at EA Customer support:  https://help.ea.com/contact-us

I recommend that you use the telephone option and the “call me” option so you don't have to stay on hold for a long time.
