(This didn't work for me - all the fields were blank - but it has worked for others.) You may not see the Promo key or the Cerberus key, but since buying the DLC bundle on Origin gets you everything anyway (including the pre-order DLC), this isn't a major concern imo. Your Digital Deluxe Game Key should be displayed to the right. From the menu on the left, select the entry labeled 'Game'.

Open the Binaries folder, and double-click MassEffect2Config.exe. One possible way to view your game key is to right-click the game title, choose Manage, then click Browse Local Files. This affects Mass Effect 1 and 2 and other games as well. EA deleted a large number of game keys from Steam due to an exploit of the EA Play subscription service. Edit, February 2021: There has been some confusion about where your Mass Effect 2 Steam keys are located.
