To open the door in the right hall in the Base Zone area you will have to find 3 key cards. Here are the locations.
Keycard #1. Go to Master Control Zone and talk to the Man with Afro about 5 times until he gives you the keycard.
Keycard #2. Can be found in the western room in Storage Zone. Here you will have to solve a small bridge puzzle. First go down to the left and press the button. Now go around the right side of the entrance until you go down a ramp and see a qhite screen. Press it ands continue until you find another switch behind some boxes. Activate it and continue across the white bridge. Finally, press the final panel to reach the room in the corner with the chest. The keycard will be on the floor just outside this room.
Keycard #3. You will obtain this keycard automatically after defeating the mini boss during the Road To Revival side quest (the same side quest that will unlock the door to the hall where the triple keycard door is found).
