BFH Code

Nobody here on the EA Answer HQ can provide you a key. To get a key you must apply for the closed beta here: http://www.battlefield.com/hardline/beta and after you apply you can check on the status of the daily key distributions here: http://help.ea.com/en/article/battlefield-hardline-beta-invite-status/ (note you cannot check on your individual key request, only if EA is finished giving out keys for the day).

Also keep in kmind that not everyone who applies will get a key so remain patient.
