Re: I have a disk BF3 premium but CD key not work

If you purchased a brand new copy of the BF3 Premium edition (not a pre-owned 2nd hand copy) and the code is not working then you will need to contact a Game Advisor 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. (The call back function is restricted to north American residents only)

1 Click on the following link: https://help.ea.com/contact-us
2 Make sure you are logged in (top right corner)
3 Click on the blue button "Contact a Game Advisor"
4 Enter the name of your game or product (or "Origin" for account-related issues) and click "Find Solutions"
5 Select the type of issue and the platform you play on, and click on "Find Solutions".
6 Click on the blue button "I still need help" if the FAQ articles do not apply to your situation.
7 Select a contact option. Note that you may get different contact options depending on your country.
