The Stella Montis Archives Key is a single-use key in ARC Raiders. It opens a locked Archives room inside the Stella Montis interior complex.
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 the door is opened, the key is consumed.
How to Get the Stella Montis Archives Key
This key is a random drop.
You can obtain it through normal gameplay by looting:
-
residential interiors
-
desks, drawers, and storage furniture
-
backpacks and containers
-
other players
Keys appear more often in amber / orange map zones, simply because those areas contain more interiors and searchable objects. Over time, this is where most keys come from.
There is no fixed route or method to force this key to drop.
If you don’t want to wait for it, LevelUpper provides ARC Raiders key delivery and boosting services, handled entirely in-raid through normal gameplay and extraction.
Night Raids
Night Raids matter for two reasons:
-
keys drop more often during Night Raids
-
locked rooms opened at Night roll better loot
If you are going to use a single-use key inside Stella Montis, Night Raids are the correct timing. Opening this room during a daytime raid is simply less efficient.

Final Thoughts & Ranking
The Stella Montis Archives Key is worth using when you are already nearby.
The room itself offers solid loot potential due to its size and number of containers.
This key makes sense when:
-
you are already committing to Stella Montis interiors
-
you are running a Night Raid
-
you are prepared to clear ARC resistance along the way
If the area is part of your route, opening the room is a logical stop.
If it isn’t, this key should stay in storage for the time being.
Tier Placement
In our ARC Raiders key ranking, the Stella Montis Archives Key is placed in Tier B.
Tier B keys offer strong loot volume and reliable value, but have minor downsides. The Archives room qualifies due to its large size, high container count, and consistent loot potential. It narrowly misses Tier A because accessing it requires sustained interior routing through Stella Montis, making time and exposure the primary tradeoff rather than loot quality.

FAQ
Yes — if you’re already committing to Stella Montis interiors.
The Archives room itself is large and packed with searchable containers, which gives it solid loot potential. The key isn’t wasted on a tiny side room or a single container. The real question is whether your run already takes you deep into Stella Montis. If it does, opening the Archives room is a logical stop. If it doesn’t, the travel cost usually isn’t worth forcing.
The key is used deep inside the Stella Montis interior complex, in the Archives section.
Reaching it requires moving through multiple interior floors, corridors, scanners, and staircases. ARC units are present along the route, and player traffic is common because Stella Montis is a high-value area. The Archives room itself has two locked doors, and opening one does not unlock the other — each door requires its own key use.
The Archives room is large, and its value comes from container count, not a single high-roll item.
Inside, you’ll typically find many drawers, cabinets, bags, storage containers, and breachable objects. This creates consistent loot volume rather than a single jackpot roll. Results are still RNG-based, but the number of searchable objects gives the room reliable baseline value compared to smaller locked rooms.
Absolutely, since Night Raids are the correct timing for this key.
Night Raids matter for two reasons: keys drop more often, and locked rooms roll better loot. Because the Archives Key is single-use and requires a long interior route to reach, using it during a daytime raid is simply less efficient. If you’re spending the effort to reach the Archives room, Night Raids maximize the return.
