Let’s break it down step by step.
What Is the Stella Montis Security Checkpoint Key in ARC Raiders?
The Stella Montis Security Checkpoint Key is a single-use access key in ARC Raiders that unlocks a locked inner room within the Security Checkpoint on the Stella Montis map.
Important details:
-
Rarity: Rare
-
Usage: One-time use (consumed upon opening)
-
Map: Stella Montis
-
Room Type: High-value locked security office
-
Loot Tier: Epic and rare augment blueprints
Unlike the main Security Checkpoint area, which is accessible to all players (and often heavily contested), this key unlocks the inner locked room, where the best rewards are stored.
In 2026, after patches fixed earlier issues (including a one-way door bug), the room now functions as intended—enter, loot fast, and get out.
This key represents a classic high-risk/high-reward mechanic in ARC Raiders’ extraction-based gameplay. If you die before extracting, you lose the key—unless you’ve stored it properly.
Key Spawn Locations – Where to Find the Security Checkpoint Key
The Stella Montis Security Checkpoint Key does not spawn in a fixed location. It appears randomly in residential-style loot containers across multiple maps.
You are looking for:
-
Wooden drawers
-
Cabinets
-
Suitcases
-
Lockers
-
Backpacks
-
Crates
-
Bags
Let’s break down the best farming locations in 2026.
Dam Battlegrounds (Best for Beginners – Low Raider Activity)
If you’re new or want safer farming routes, Dam Battlegrounds is your best bet.
Top locations:
-
Pale Apartments
-
Ruby Residence
-
Pattern House (outskirts area)
These areas typically have lower enemy activity, making them ideal for players who want to farm keys without constant PvP pressure.
Pro Tip: Run light gear and prioritize mobility. Don’t overcommit to fights—your goal is container farming.
Buried City (Higher Risk, Higher Traffic)
Buried City offers solid spawn chances but comes with higher raider density.
Best search zones:
-
Grandioso Apartments
-
Houses east of Abandoned Highway Camp
These areas are more contested. Expect ambushes.
If you’re confident in PvP or running with a squad, Buried City can be efficient—but solo players should move cautiously.
Stella Montis (On-Map Spawns)
Yes, the key can also spawn directly on Stella Montis itself.
Check:
-
Lobby suitcases
-
Trash cans
-
Business Center
-
Medical Research building
-
Cultural Archives
Because Stella Montis is already a high-value map, these spawns can be competitive.
Important Farming Tip
Always store the key in your safe pocket immediately after finding it.
If you die and it’s in your backpack, you lose it.
In high-traffic maps, respawns are possible—but you don’t want to rely on luck twice.
Where to Use the Stella Montis Security Checkpoint Key
Once you have the key, it’s time for the real mission.
Map: Stella Montis
The Security Checkpoint is located inside an indoor-industrial complex.
Exact steps:
-
Enter the northern Lobby section
-
Move toward the Security Bridge POI
-
Find the barricaded “security” door
-
Breach or vault through the checkpoint entrance
-
Inside the room, locate:
-
First door on your right
-
Behind reception desk
-
Move to end of room
-
Turn left, then right
-
That’s the locked inner room.
Use the key → door opens → key is consumed.
Important note:
The main checkpoint area is accessible without the key, and it’s often contested early in matches. The key unlocks the secondary locked loot room only.
Loot & Rewards – Is It Worth It?
Now for the part everyone cares about: the loot.
The room itself is small, but don’t let the size fool you.
Inside you can find:
-
Lockers
-
Black loot boxes
-
Raider backpacks
-
Weapon crates
-
Rare augment blueprints
-
Epic-rarity gear
One player reported pulling nearly 20 items from a breach cabinet, essentially filling a full backpack in one room.
High-value items may include:
-
Looting MK3 Survivor blueprint
-
Rare weapon attachments
-
High-tier crafting materials
-
Endgame augment components
Before unlocking the room, loot the surrounding checkpoint area first. Weapon lockers nearby can also drop valuable blueprints.
This makes the entire Security Checkpoint a stacked loot zone.
High-Risk, High-Reward Strategy (2026 Meta Tips)
