Finding locked doors is a regular part of ARC Raiders’ extraction loop, and the Stella Montis Medical Storage room is one of the most rewarding early-run stops on the new map. The challenge isn’t the loot inside—the difficulty is securing the Medical Storage key and reaching the lock without getting caught by Raiders or ARC units.

How to Find Medical Storage Keys in ARC Raiders
Keys in ARC Raiders don’t follow fixed spawn points. Instead, they follow a wide-area RNG container system, meaning any loot container can technically drop them. However, some locations produce keys more consistently than others.
Residential and multi-room apartment clusters often hold the highest key spawn density, making them ideal areas to search before heading toward Stella Montis.
Best Places to Find the Stella Montis Medical Storage Key

1. Residential Blocks in Dam Battlegrounds (Ruby Residence)
- Multi-floor structure packed with small containers.
- Keys frequently appear in living quarters and hallways.
- You may need to check every crate—nothing here is guaranteed.
2. Research & Administration Building (Dam Battlegrounds)
- Upper floors see regular key spawns.
- Rooms have a mix of research desks and utility lockers with strong loot value.
- This building is worth sweeping on every run.
3. General Residential Zones Across the Map
- Though not reliable individually, every container has a chance to drop the Medical Storage key.
- Great place to search if your route naturally passes through housing zones.
4. Rare Random Spawns in Any Container
- Keys sometimes appear in unlikely areas such as Buried City, proving RNG is always in play.
Regardless of where you search, bring a safe pocket so you don’t lose the key if you die.
How to Reach the Medical Storage Door in Stella Montis
Once you secure the key, head into Stella Montis, and look for the Medical Research section of the zone. Expect tighter combat spaces and occasional Raider activity.

Step-by-Step Route to the Door
Follow this straightforward route to find the Medical Storage door:
- Enter the Medical Research area: This zone is compact, with a mix of hallways, locker rows, and stair access points.
- Move toward the northern side of the complex: This is where most navigation landmarks align.
- Find the set of red lockers positioned centrally: These lockers sit near a stairwell—use this as your key indicator.
- Locate the door directly across from the stairwell: The Medical Storage door is easy to miss because it blends in with the metal surroundings, but the placement is consistent.
- Use the key to unlock the room: Once unlocked, the room stays accessible for your run.
Players spawning from the southern entrance of Medical Research will naturally pass this door after going straight and cutting left at the corridor.
