Stella Montis takes ARC Raiders away from open ruins and drops you into a dense industrial complex, all corridors, stairwells, and blind corners. That layout makes key-locked rooms especially easy to miss, and the Stella Montis Assembly Admin Key is one of the easiest to walk right past.
The key only works on a single door tied to the Assembly area, and it is consumed when you use it. Navigating to that door efficiently can be the difference between cashing out rare loot and wasting a rare item on a doomed run.
ARC Raiders: Where To Use the Stella Montis Assembly Admin Key
The Stella Montis Assembly Admin Key opens a locked office in the Assembly section of the map. It is tied to one specific door and cannot be reused.
| Detail | Assembly Admin Door Info |
|---|---|
| Map | Stella Montis |
| Zone | Assembly / Assembly line |
| General position | Upper side of the Assembly area, near conveyor lines and a descending ramp |
| Approach | Move along the top of the Assembly, through a central corridor, then around a corner to the locked door |
| Alternative access | Secondary entrance from above into the same space |
| Key usage | Single-use; consumed on unlock |
| Door persistence | The door you unlock stays open for others; other doors stay locked |
The door sits in the Assembly segment on the upper (north/top) side of the Stella Montis layout, close to the conveyor line and near a ramp that leads down into the production floor. From this upper area, you head into a central corridor, follow it around a corner, and the Assembly Admin door is waiting at the bend.
The exact door can be easy to miss because it does not dominate the environment like a major POI entrance. It looks like a regular industrial door with small “Assembly Admin” labeling rather than a huge overhead sign. Moving slowly and checking each door on the corridor wall helps avoid walking past it.
There is also a way to drop in from above into the same room. That alternate route does not remove the need for the key: the Assembly Admin key still controls the main door, and that door is the one that remains open once unlocked.
How to reach the Assembly Admin door from common positions
Spawns in Stella Montis are scattered, but most routes into the Assembly Admin hallway can be boiled down to a couple of patterns.
| Starting point | Route to Assembly Admin |
|---|---|
| Near Loading Bay | Move into the Loading Bay, then use ramps and stairs to climb toward the upper Assembly line, aiming for the conveyor area and central corridor. |
| Near Assembly Workshops | Push through the Assembly floor, using catwalks or side corridors to reach the top side near the conveyor line, then enter the corridor that bends toward the locked door. |
| Other internal spawns | Orient yourself toward Assembly on the map, then navigate vertically until you are on the upper level where conveyor machinery and the downward ramp sit. |
Because Stella Montis stacks multiple floors, it helps to think vertically rather than just hugging walls. The Assembly Admin door is not at ground level; it is closer to the upper runs where the assembly line and conveyors are placed.
How to get the Stella Montis Assembly Admin Key
The Assembly Admin Key follows the same basic logic as other keys in ARC Raiders: it is a loot drop that appears in containers and is typically single-use. What makes it different is where it tends to show up most often.
| Aspect | Stella Montis Assembly Admin Key |
|---|---|
| Item type | Key (uncommon, single-use) |
| Best map to search | Stella Montis |
| High-yield POI #1 | Medical Research (west side of Stella Montis) |
| High-yield POI #2 | Assembly Workshops |
| Primary container types | Drawers in desks and tables, plus lockers and similar loot containers |
| Global spawn behavior | Follows general key spawn rules (residential and administrative spaces, containers, occasional restricted zones) |
Medical Research on the western side of Stella Montis is a reliable hunting ground. That zone typically carries strong loot in general and tends to throw up keys, including the Assembly Admin Key, when you methodically clear every room.
The Assembly Workshops offer a secondary route: sweeping workbenches, side offices, and storage corners there can turn up the key as well. Across maps, keys share a common pattern: they like to hide in small containers, especially drawers built into desks and tables, with lockers and bags as additional options.
Keys can also appear in residential or administrative areas outside Stella Montis, including houses in Blue Gate or comparable buildings on other maps, but targeting Medical Research and Assembly Workshops keeps the search focused.
Assembly Admin room layout and loot
Unlocking the Assembly Admin door gives access to a compact but dense loot space built across two levels. The room is not a boss arena; it is essentially an administrative overlook with multiple containers and surfaces to strip for parts.
| Room feature | Description |
|---|---|
| Floors | Two levels connected inside the same locked zone |
| Loot density | High number of containers and loot spots relative to room size |
| Typical rewards | Crafting materials, weapons, and higher-tier items |
| Notable possible drop | Weapon blueprints, including rare examples such as Venator |
| RNG behavior | Fully random; runs can range from basic materials to standout drops |
The value of the Assembly Admin room is in how many chances at a good roll it offers. Every cupboard, cabinet, and container is another dice throw against the game’s loot table. Some runs will yield mostly basic crafting resources, which are still useful for building out gear. Other runs can pay out with rare schematics, including weapon blueprints.
ARC Raiders leans heavily on RNG, so there is no fixed guarantee that a particular blueprint will appear in this room or how often it will do so. The important point is that the loot pool in these locked spaces reaches into higher tiers than what you typically see in unguarded hallways nearby.
How the Assembly Admin Key fits into wider Stella Montis key usage
The Assembly Admin Key is one of several Stella Montis-specific keys, all of which live inside the same tight, indoor design. Each is tied to a single door that hides a focused reward space, and each key is consumed when used.
| Key | Door location | Notable path detail |
|---|---|---|
| Stella Montis Assembly Admin Key | Assembly, upper side of map near conveyor line and downward ramp | Reach the top side, follow the central corridor, turn at the corner to find the locked admin door. |
| Stella Montis Archives Key | Large door at the very end of tunnels in the Seed Vault area | Follow tunnels, climb pipes, pass a shredder, then use the key on the door at the far end. |
| Stella Montis Security Checkpoint Key | First door on the right inside the Security Checkpoint room on the Operator map | From the lobby, pass the main checkpoint, enter the small room behind security, then left and right at the end. |
All of these doors operate with the same core rules:
- The key is consumed once you unlock the door.
- Only the door you open remains available to other players; adjacent locked doors stay closed.
- The reward rooms generally hold higher-value loot than open zones, but rewards still roll on RNG.
Because keys are rare and bound to specific rooms, they are best saved for runs where your squad is geared, organized, and realistically able to extract. Spending a Stella Montis key on a chaotic, under-prepared push into the map can easily end with a wipe in the corridors and no payoff.
Within that context, the Assembly Admin Key is a straightforward proposition: it buys a high-density loot room in one of the map’s most navigationally confusing areas. Learn the upper-Assembly route, keep the key safe until you are ready to commit, and treat the room as a targeted stop on a planned Stella Montis extraction path rather than a spur-of-the-moment detour.
