The Stella Montis Assembly Admin Key is a one-time-use key in ARC Raiders that opens a locked admin room inside the Assembly area on the Stella Montis map.
Before anything else:
-
Always put the key in your Safe Pocket
-
The locked door has red indicator lights
-
Close the door after entering if you don’t want to get pushed
Once you open the door, the key is consumed.
How to Get the Stella Montis Assembly Admin Key
Like most keys in ARC Raiders, the Assembly Admin Key is a random drop.
You’ll usually find it while looting:
-
interior-heavy areas with lots of rooms
-
desks, lockers, drawers, and other searchable furniture
-
backpacks and containers
-
other players during PvP
Where keys drop more often
Keys show up more reliably in amber / orange and red loot zones. These areas are packed with interiors and personal storage, which is exactly where keys tend to appear over time.
If you’re running raids that focus on open terrain or pure ARC combat, you’ll almost never see keys. Interior-heavy routes are what matter.
Night Raids
Night Raids are always the correct choice for keys.
-
Keys appear more often at Night
-
Loot inside locked rooms rolls better
-
Using a single-use key during the day wastes potential value
If you’re opening this room, do it at Night.
There is no way to force this specific key. You either loot it naturally or get it off another player.
If you don’t want to wait for RNG, we offer ARC Raiders key delivery, alongside a full ARC Raiders boosting service for keys, blueprints, and other progression blockers. Everything is done in-raid through normal gameplay and extraction.
Where the Assembly Admin Key Is Used
The Stella Montis Assembly Admin Key is used on the Stella Montis map, inside the Assembly.
This part of the map is dense, vertical, and confusing if you’re not familiar with it.
How to reach the door (reliable route)
The most consistent path is:
-
enter Robotic Sandbox
-
find the tunnel leading upward into Assembly
-
follow interior signage toward Assembly areas
-
the locked Admin door sits along the east side of Assembly, near the tunnel exit
The Assembly Admin room has two locked entry points. Opening one door does not unlock the other — only the specific door you use will open.
What to expect on the way
-
heavy ARC presence
-
frequent player traffic
-
tight corridors with limited escape routes
Reaching the door is often harder than looting the room itself.
What It Unlocks
The Assembly Admin room is a small, enclosed interior space.
Inside, you’ll usually find:
-
lockers and cabinets
-
crafting materials and components
-
valuables and consumables
-
occasional blueprints
Loot quality is highly RNG-dependent. Some runs feel fine, others feel like a waste of time for the effort it takes to get there.
Once the room is looted, that’s it — the key is consumed.
Final Thoughts & Ranking
The Stella Montis Assembly Admin Key is a low-priority key.
It’s not terrible, but it’s not worth planning a raid around and doesn’t justify detours on its own. The room itself is small, the loot is inconsistent, and the approach is awkward.
Best way to use it:
-
only during Night Raids
-
only if you’re already moving through Assembly
-
never as the main goal of a run
Think of it as a bonus stop, not a destination.
Tier Placement
In our ARC Raiders key ranking, the Stella Montis Assembly Admin Key is placed in Tier C.
Tier C keys offer situational value but limited upside. The Assembly Admin room qualifies due to its small size, inconsistent loot, and awkward approach through a high-risk interior zone. While usable during Night Raids when already routing through Assembly, it does not justify dedicated planning or detours.

FAQ
The Assembly Admin Key is used inside the Assembly area on Stella Montis, which most players reach through Robotic Sandbox. From Sandbox, there’s a tunnel that leads upward into Assembly. Once inside, follow the Assembly signage and move toward the east side of the structure.
The locked Admin door sits close to where the tunnel exits into Assembly. There are two possible entry sides, which means one door can already be opened while the other remains locked. Always check both sides before committing the key, otherwise you can waste it on an already-looted room.
This area is tight, vertical, and easy to get turned around in if you don’t know the layout — most failed attempts happen because players get lost, not because the room itself is dangerous.
The room contains a small set of admin-style containers: lockers, cabinets, and standard searchable storage. You’re usually pulling:
-
crafting materials and components
-
consumables and utility items
-
valuables for currency
-
occasional blueprints
There is no guaranteed weapon case, and epics are possible but not common. The room can spike into good value, but most runs land in the “okay but forgettable” range.
This is not a jackpot room. It’s closer to a mid-tier interior loot stop with RNG swings.
Night Raids make a noticeable difference for this key.
Night Raids:
-
increase overall loot quality
-
improve the average value of locked rooms
-
make small rooms like Assembly Admin more likely to pay off
Because the room doesn’t have guaranteed high-tier containers, using this key during a daytime raid often feels wasted. At Night, the same containers have a much better chance to roll into something worthwhile.
If you’re going to spend this key at all, Night is the only sensible time to do it.
