online pass is removed but buy't my game 2e hand

BF3 still requires the online pass to function online.  Online passes are suppossed to be free in the Xbox Live marketplace.  Check the BF3 in game store, and if it's not there check directly in the BF3 section of the Xbox Live marketplace for the free online pass.

I'am having similar problems i have done that and it still isn't showing up on the xbox marketplace and the pass isn't in the BF3 store either. what do i do?

The Xbox Live marketplace is currently experiencing some issues and this might impact your ability to locate or download the online pass app. 

Head to the official Xbox Live support website for more details: http://support.xbox.com/xbox-live-status

Once the marketplace is fully back up and running please try again searching for the online pass for Battlefield 3. Check the in-game store, the Xbox Live market place directly, or select Multiplayer and it should (in theory) prompt you to either input a code or purchase it directly. This purchase should be free of charge.
