I'm in this situation: [...] here's a destroyed sentry bot and two dead marked men with arc welders in the main room, and a door you cannot open; to the right (west) is a mainframe. Using the codes you got from the base commander's desk, have ED-E unlock the mainframe and open the silo's doors.

I got the codes from the base commander's desk, how can i give them to ED-E in order to make him unlock the mainframe? I tried all the possible interactions but it is not working!
