Upon entering Atomfall’s Interchange for the first time, you’ll notice several doors that are locked. Some of these need Atomic Batteries to unlock, while others require specific keys and a deeper investigation to open them. One such door you might find right at the Slatten Dale entrance is the Site Office, which is securely sealed shut. Therefore, if you wish to access it and discover its contents, you’ll have to locate the Site Office Key first. This key will grant you entry to many of the game’s locked areas, which often lead to valuable treasures and information.
To acquire the Site Office Key in Atomfall, advancement within the game is essential to open up additional areas of The Interchange and secure useful gear. If you’re finding difficulty locating the Site Room Key or figuring out the steps needed to obtain it, look no further as this guide has got your back!
Where To Find The Site Office Key In Atomfall (Site Office Key Location)
After locating the entrance to Atomfall’s Interchange via Slatten Dale, you’ll spot a building close to the entryway on your left, which is known as the Site Office. However, to retrieve the Site Office Key, it’s essential to complete some preparatory tasks first. Start by reactivating the Central Processor and Data Store Delta within the Interchange using one of Atomfall’s multiple Atomic Batteries.
It’s important to secure a Signal Redirector prior to moving forward, so ensure that you have one ready before you continue.
How To Get Into Robotics And Restore Power To The Robotics Lower Level
Once you’ve activated Data Store Delta, it grants entry to the Robotics sector of the Interchange, as illustrated on the map provided. To reach the Robotics zone, maneuver cautiously around the B.A.R.D robot and turrets located in the initial area of Data Store Delta. Then, proceed through the door marked ‘Robotics’ that lies ahead. If possible, try to slip by without attracting much firepower damage from the robot.
Inside Robotics, you’ll have to employ the Signal Redirector towards the orange wall panels near the wall to divert the power. This action will enable you to open the large gray door at the end of the ‘Lower Level’ room, which is currently locked and lacks power. The power can be located and re-routed by scanning and hacking the yellow panels on the walls in the specified areas of the room, as indicated in the instructions below and depicted above:
1. In the southwest corner of the room.
2. Along the eastern wall near the massive gray door.
3. On the north wall, adjacent to the staircase leading to the upper level.
4. In the northeastern corner of the room.
By successfully re-routing the power, you’ll be able to open the massive gray door.
- Through the window right of the Robot Assembly room, accessed by standing on the wooden box inside, with a series of separate yellow panels on the wall to re-route leading to the Lower Level door.
- Through the window left of the Power Control Beta room, with another set of yellow wall panels to re-route inside and just outside the room.
- Pulling the two Wing Power Control switches, one inside Robot Assembly and another inside Power Control Beta.
After completing the outlined steps, a strong electric field forms around the Lower Level door. To resolve this issue, carefully hop onto the crates and platforms situated before the Lower Level door. Locate the wall panel on its left side, then activate the Signal Redirector to cut off the electricity. Now, you can press the lock release button to open the door leading to the Lower Levels, a crucial area for your search of the Site Office Key.
How To Find The Construction Site Through The Robotics Lower Level (Site Office Key Location)
After being unlocked, make your way down the incline to access the Lower Robotics Facility, employing the Signal Redirector on the yellow console to reactivate the power for the door further on, thereby opening the Robotics Maintenance Area. To proceed, you’ll want to pass through the orange ‘Control Room’ door located on the far right side of the room, as illustrated in the diagram. Once secured inside, carry on until you locate and follow the smoky, circular tunnel that leads you to another part of the Interchange.

After going through the tunnel, you’ll come across a run-down section of the Interchange, which appears to house the Construction Site situated beneath the Site Office. Keep moving forward to locate the Site Office Key on a deceased individual surrounded by a pack of vicious Feral enemies, as depicted in the image above. Be prepared as many of them activate upon your approach, requiring you to swiftly eliminate them from a distance and secure the Site Office Key from the corpse once it’s safe, as demonstrated in the video below:
