Where can I find key to Vault-tec mainframe?

  1. I've been searching the vault-tec HQ for the key to reach the mainframe. I've unlocked all three computers, but I can't get through the door to access it without a key. Anybody know where it is?

  1. There is no key. You deactivated the security through the megabrain or whatever it's called. Now the door is permanently closed.

    You'll need to load an older save, do it all again, but don't touch the security device on the robot this time.
