Entering product key.

When you bought your game directly from the Origin store, the game should get automatically granted on your Origin account as soon as the payment is complete. When you see the game in your "My Games" library, click with the right mouse button on BF4 and choose "Show game details". You can see the product key on the right side of the next screen. If you haven't got the game automatically activated on your account yet, check your e-mails as well as your Origin order history. 

Cheers
