Stella Montis is one of the most lucrative—but also most dangerous—maps in ARC Raiders. As the game’s first fully indoor environment, it’s packed with tight corridors, layered verticality, and locked loot rooms that can dramatically swing a raid in your favor. One of the most sought-after of these is the Assembly Admin room, which requires the Stella Montis Assembly Admin Key to access.

If you’ve managed to pick up this key—or are actively farming for it—this guide breaks down where the key drops, exactly where to use it, and how to loot the room safely without losing everything to PvP or ARC patrols.

What Is the Stella Montis Assembly Admin Key?

The Stella Montis Assembly Admin Key is an uncommon loot-room key that unlocks a sealed admin office inside the Assembly sector of Stella Montis. While it isn’t guaranteed to drop every run, it’s absolutely worth holding onto when you find one.

Why? Because the room it opens contains:

• Multiple residential-style containers

• A strong chance at high-value crafting resources

• Occasional epic-rarity items

• Enough loot density to quickly fill your backpack

For players focused on efficient progression and extraction profit, this is one of the better indoor loot rooms available early on.

How to Get the Stella Montis Assembly Admin Key

Unlike fixed quest items, this key is part of the shared residential loot pool, meaning it can drop from common household containers across several maps.

Best Container Types to Search

The key can appear in:

• Wooden drawers

• Filing cabinets

• Metal drawers

• Suitcases

• Trash bins in residential or office-like areas

Because it shares a loot pool with other keys, consistency is more important than location—you want density, not a single lucky spot.

Best Places to Farm the Key

Dam Battlegrounds

This map offers some of the most reliable residential loot clusters:

• Pale Apartments

• Ruby Residence

• Pattern House

You can also extend runs into:

• Research & Administration buildings

• Hydroponic Dome Complex

These areas are relatively compact, letting you check dozens of containers quickly.

Buried City

A strong alternative with lower early-game pressure:

• Grandioso Apartments

• Houses east of the Abandoned Highway Camp

These zones are ideal for slower, methodical looting with reduced PvP risk compared to Stella Montis itself.

Stella Montis (Lobby & Business Center)

If you’re already running Stella Montis:

• Search trash cans and suitcases in the Lobby

• Check the Security Checkpoint

• Move east into the Business Center, which contains multiple office-style containers

While riskier, this lets you farm the key and immediately use it in the same raid.

Where to Use the Assembly Admin Key on Stella Montis

Once you have the key, it’s time to put it to work.

Exact Door Location

• Head to Stella Montis → Assembly Area

• Move toward the Central Corridor

• The corridor is located in the upper western section of the map

This zone is notorious for player traffic, so caution is mandatory.

Getting There Safely

From the Lobby:

• Move east through the machinery-filled open section

• Avoid adjusting bridges unless necessary

• Drop down quietly instead of sprinting across exposed paths

Stealth matters here more than speed.

Unlocking and Securing the Room

Once inside the Central Corridor:

• The Assembly Admin door will be on your right-hand side

• Use the key to unlock it

Immediately after entering:

1. Close the door behind you

2. Place a Jolt Mine near the entrance if available

3. Listen carefully—sound travels far indoors

This single step can save your entire run.

What’s Inside the Assembly Admin Room?

The room is split across two floors, both packed with searchable containers.

First Floor Loot

• Cabinets and drawers

• Computer monitors

• General office storage

Second Floor Loot

• Similar container density

• Higher chance of valuable crafting components

You can clear the entire room in just a few minutes if uninterrupted.

Extraction Tips After Looting

Before leaving:

• Move your best items into your safe pocket

• Reload and heal—ambushes are common outside the door

Then:

• Head toward the nearest extraction point

• Avoid retracing obvious paths if other players are nearby

The key opens the door, but extraction is where profit is decided.

Is the Key Single-Use?

Yes. Like most loot-room keys in ARC Raiders, the Stella Montis Assembly Admin Key is consumed on use, so make sure you’re ready to capitalize on it before opening the door.

Struggling to Farm Keys or Extract Safely?

Stella Montis is unforgiving, especially for solo players or those still learning PvP routes. Many players turn to ARC Raiders Boosting at GladiatorBoost to speed up progression, secure high-value extractions, or farm rare keys without unnecessary losses. It’s a practical option if you want consistent results without burning gear every run.

Final Thoughts

The Stella Montis Assembly Admin Key is one of those items that quietly enables huge progression gains. It doesn’t look flashy, but the loot density behind that door can fund multiple future raids if you extract successfully.

Farm residential containers consistently, approach the Assembly Area carefully, and always plan your exit before unlocking the door.
