Where do I use the Control Room Key in Mor Ardain's Old Factory?



  • I found a Control Room Key by Bulge Harbor in the Old Factory of Mor Ardain. I vaguely remember a locked door in the factory, but I can't remember where it was. I can find information about https://gamefaqs.gamespot.com/boards/204208-xenoblade-chronicles-2/76191483 , but not the Control Room itself.

  • The Old Factory's Control Room is near where you were held prisoner. Fast travel to the Ether Refinery Corridor then the door will be behind you down the hallway.
