The Stella Montis Archives Key is one of the newest location-specific keys in ARC Raiders, and it gives access to a locked Archives room inside the Stella Montis complex. If you’ve pulled this key from a locker on Dam or Spaceport and have no idea where to use it, you’re not alone. The key belongs strictly to the Stella Montis map and cannot unlock anything on older regions.
What the Stella Montis Archives Key Is Used For
The Archives Key is tied to a single interior zone inside Stella Montis. It opens a large garage-style door that leads into the Archives room, a loot-dense area designed similarly to high-value interiors on other maps.
The door is located deep inside the tunnels near the Seed Vault section of Stella Montis, requiring players to move through industrial corridors, climb pipes, and push past roaming ARC units before reaching it. The key is consumed upon use.
How to Find the Stella Montis Archives Key
Like all non-quest keys in ARC Raiders, the Archives Key spawns randomly across multiple maps. There are no fixed spawns, but the community has consistently reported better results in residential-style loot zones, which contain dense clusters of searchable containers.
Best Places to Search
1. Blue Gate – Residential Houses
Players frequently pull Stella Montis keys from lockers and bags inside Blue Gate homes. These buildings follow the same key-spawn mechanics as Dam and Buried City residential blocks. Many keys, including the Archives Key, appear here during regular scavenging runs.
2. Buried City – Residential Pockets
Another strong source is the Buried City housing clusters. Keys tend to appear in side rooms, abandoned apartments, and compact loot rooms.
3. Dam Battlegrounds – Ruby Residence
Ruby Residence is a standout hotspot thanks to its huge number of containers. Players often walk out with multiple keys per visit, making it a reliable farming spot for all Stella Montis keys.
4. General World Drops
Archives Keys can also appear from:
- Lockers and crates scattered across maps
- Administrative buildings
- Hidden caches
- High-traffic areas with respawning containers
There is no guaranteed spawn, so consistent looting and extractions are what matter most.
How to Reach the Archives Door in Stella Montis
Once you finally secure a key, you can use it inside the Stella Montis map when it appears in rotation. The Archives room sits deep inside the tunnels branching from the Seed Vault. Reaching it requires navigating narrow indoor paths and vertical transitions.
Starting Point: Seed Vault Tunnels
Begin near the Seed Vault entrance. From here, follow the tunnel directly forward into the industrial interior.
Climb the Pipe Network
You’ll encounter a vertical section where pipes act as a climbable path. Move upward to the higher walkway.
Advance Toward the Shredder Corridor
Continue forward until you reach a long corridor patrolled by ARC units. Shredders sometimes appear here, and they can easily turn this into a fatal choke point. If a Shredder is present, avoid direct engagement—use cover and let it drift away before pushing through.
The Archives Door Location
At the end of this corridor, the Archives Door will appear on your right. It’s a large, garage-style door requiring the Stella Montis Archives Key to open.
Once inside, close the door immediately. This prevents enemies, especially Shredders, from following you in.
The Archives room functions as a high-tier loot chamber similar to other locked interiors across the game. Expect densely packed containers, valuable materials, and potential late-game upgrades. Loot quality makes the key worth saving rather than selling.
Should You Keep or Sell the Key?
Since the key is single-use, weighs almost nothing, and occupies only one stash slot, keeping at least one copy is recommended. Selling the key gives short-term Raider Credits, but you’ll miss out on the future loot run once Stella Montis is in rotation.
If you’re short on stash space early on, selling is understandable—but long-term players should hold onto at least one Archives Key.
The Stella Montis Archives Key is part of the larger key-driven structure ARC Raiders is building for its newest map. While the key drops on existing locations, it’s meant specifically for the Archive room hidden deep inside Stella Montis’ tunnel network. With residential houses and Ruby Residence being your most reliable farming spots, and a clear route toward the Archives door once inside the map, you can prepare now for profitable future runs.
