Each Remote Systems command has three parts: a command button, an equipment button, and an ID number that shows on that equipment's camera. Read the ID off the camera feed. The numbers guides report are below.

Where it is

It's in the Control Room of SWDP – Different in Part 6 (Chapter 15: Trying Again). Get in with the Access Card from beside the bed, past the gap in the wall behind the JOE door. Turn the panel on with the two switches below the printer.

Round 1: Valve B and Filter A

Start Filter AStart (column 1, row 2)Filter (column 4, row 3)Read from the filter camera: 130 in two guides, 103 in one

The panel then gives code 0825 for the locker on the right. Inside is the AUX Key. Next, set the AUX line switches.

Round 2: after the AUX switches

Then go downstairs and turn the red Valve F wheel by hand.

Guides disagree on the Valve B and Filter A numbers. If an ID is rejected, check that equipment's camera and type the number you see.

While the door controls are open, you can also unlock doors 793 and 621. They hold the Gold Coin and Strange Book #3. Both are New Game Plus items for the Dog and Sci-fi endings.
