Stella Montis is one of the most distinctive zones in ARC Raiders, offering a dense, fully enclosed environment packed with hidden compartments, layered pathways, and loot-rich chambers. Among these secret rooms, the Assembly Admin Room stands out as one of the most rewarding—yet also one of the most contested—locations in the entire indoor complex. Accessing it requires a specific key: the Stella Montis Assembly Admin Key.

This guide walks you through exactly where to use the key, how to reach the door safely, what to expect inside, and a few essential tips to maximize your haul while surviving Stella Montis’ notorious PvP pressure.

What the Stella Montis Assembly Admin Key Unlocks

The Stella Montis Assembly Admin Key grants access to a sealed administrative control room within the Assembly sector. This interior chamber contains multiple loot stations across two floors, making it one of the most profitable single-room stops in ARC Raiders’ early and mid-game progression.

Players who enter prepared can fill their inventories with high-value resources and even rare or epic-quality items. Because the room is isolated and easily defendable, it also becomes a temporary safe haven—if you secure it properly.

Where to Use the Assembly Admin Key (Exact Door Location)

To use the key, you’ll need to navigate into the Assembly Area’s Central Corridor, located in the upper-west section of the Stella Montis map. This zone is designed as a high-traffic funnel, making it one of the more dangerous indoor routes due to frequent player activity.

How to Reach the Door Efficiently

1. Start from the Lobby Entrance
   Push east out of the lobby and continue into the large mechanical section filled with moving industrial elements, scaffolding, and walkways.

2. Move Through Without Adjusting Bridges
   Although the bridges can be manipulated, doing so often creates noise—and noise attracts attention. The safer method is to drop down quietly and follow the ground-level paths toward the Assembly sector.

3. Enter the Central Corridor
   Once you reach the junction leading into the Central Corridor, keep an eye on your right-hand side. The locked Assembly Admin door is positioned just off the main hallway, easy to overlook if you’re rushing or engaged in PvP.

4. Use the Stella Montis Assembly Admin Key
   Interact with the door to unlock it. Make sure your key is stored in your safe pocket, or you risk losing it during encounters before you even reach the room.

Surviving the Approach: Essential Prep Tips

Because the route is known for ambushes, players should expect resistance. A few practical tips:

• Carry at least one Jolt Mine
  This is critical for securing the room once you’re inside. Place the mine immediately after closing the door to prevent others from barging in.

• Bring a mid-range weapon
  Corridors here are tight, but not so tight that only close-quarters weapons shine. DMRs and SMGs offer the perfect balance.

• Minimize noise
  Jumping, bridge adjustments, and long gunfights echo all the way across Assembly. Stealth drastically increases your odds of reaching the room uncontested.

• Solo runs are recommended
  The narrow hallways make three-person squads obvious, loud, and easily trapped. Solo raiders slip through much more quietly.

Inside the Assembly Admin Room: Loot Breakdown

Once inside, immediately close the door and secure it with a Jolt Mine. The room consists of two searchable floors, each with multiple containers:

• Drawers

• Cabinets

• Terminals and monitors

• Small storage boxes tucked into corners

These loot points frequently spawn high-value materials used for crafting, upgrading, and trading. Expect:

• Weapon mods

• Repair resources

• Electronics

• Occasional epic-tier loot drops

Because the room is compact and organized, you can efficiently sweep the entire area in just a few minutes.

Before Leaving the Room

1. Move anything valuable to your safe pocket
   Don’t make the mistake of extracting without securing your best items first.

2. Pick your extraction route carefully
   Central Corridor remains busy throughout most raids. Consider waiting to hear footsteps fade or taking an alternative exit toward the quieter side passages.

How to Get the Stella Montis Assembly Admin Key

The key isn’t guaranteed but can drop from several reliable sources:

• Residential zones
  These civilian sectors frequently include keycard spawns among personal lockers and containers.

• High-value facility areas
  Research labs, maintenance wings, and similar locations tend to drop rare keys more often.

Because drop rates aren’t fixed, many players farm residential sectors for consistency.

• Extract immediately after looting to avoid bottleneck ambushes.

Unlocking the Assembly Admin Room is one of the most rewarding moves you can make inside Stella Montis. With preparation and awareness, this single key can easily turn an average run into a top-tier raid.
