Learn how to find the Site Office Key in Atomfall's The Interchange. This guide details the steps to acquire the key and access the Site Office for valuable loot.

This guide details how to find and use the Site Office Key in Atomfall, located in The Interchange. You'll need to navigate through Robotics and restore power to various areas to access it.

Where to Find the Site Office Key:

1. The locked Site Office is near the Slatten Dale entrance to The Interchange. A body near the door has a note indicating the key is in Robotics.
2. To access Robotics, you first need the Signal Redirector. Obtain this by helping Simms in Wyndham Village's Town Hall, mentioning Dr. Garrows, gaining access to Skethermoor prison, and finding it on a shelf in Security.
3. With the Signal Redirector, restore power to Data Store Delta in The Interchange (accessed from Slatten Dale entrance).
4. Inside Robotics, go to the main hallway, take the first door on the right, and pull the first lever to drop a body. Loot this body for the Storage Room Key.
5. Use the Storage Room Key to enter the Storage room. Use a Radiation Resistance potion and search the B.A.R.D crate to find the Control Room Keycard.
6. Return to the main hallway, take the opposite door to the canteen, and find stairs leading up to the Control Room. Use the Control Room Keycard to restore power to the level.
7. Deal with the patrolling robot in the main hall by shooting its back and ejecting its Atomic Battery.
8. The door to the lower part of Robotics is unpowered. Use the Signal Redirector through the window of the locked room on the left to open it and access the first Wing Power Control lever.
9. Go to the opposite door, use the Signal Redirector near the window to open it. Find the second Wing Power Control lever inside.
10. Go back to the previous room, climb crates, and use the Signal Redirector on the junction box on the wall to power the right side of the door.
11. To power the door itself, navigate the electrified area by using boxes to reach and activate the junction box to the left of the door, then do the same for the junction box on the right.
12. Slide down to the lift, drop down the hole, and climb the ledge. Activate the junction box on the western wall to open the shutter on your right. Disable the turret using the junction box.
13. Proceed down the eastern tunnel (marked for The Interchange) until you find a door back into The Interchange.
14. In the main room, defeat the Ferals and the turret. Search the body to find the Site Office Key.

Using the Site Office Key:

1. Locate the stairs near where you found the key.
2. Ascend the stairs and ladder, avoiding the turret.
3. At the top, unbar the door to the Site Office.
4. Inside, you'll find resources, a desk with a Training Stimulant and a possible Recipe (e.g., Combat Stim), and a note titled “A Sea Change at Seascale?” on the wall.
