Stella Montis is ARC Raiders' endgame map — the smallest, the deadliest, and the one with the highest-value loot in the game. The Medical Storage Key opens a small, sealed room tucked into the Medical Research zone, and it's one of the cheapest keys to carry: it's only Uncommon, weighs almost nothing, and you'll find it more often than the map's Rare keys. The catch is that the room is a quick, RNG-heavy clear rather than a guaranteed jackpot — so the smart play is knowing exactly where the door is, how to reach it fast, and when it's actually worth burning the key. This breakdown gives you all three, cross-checked against the ARC Raiders Wiki and the guides that ran it.
Quick answer (TLDR): The Stella Montis Medical Storage Key is an Uncommon, single-use access key (weight 0.25, sells for 100 Coins) that unlocks a locked storage room inside Medical Research on Stella Montis (arcraiders.wiki). The door sits on the lower level of Medical Research — take the stairs down and look for the locked door with red indicator lights (destructoid, levelupper). You get the key only from scavenging — best odds in residential interiors, desks, drawers and medical furniture. Inside is a small room of medical consumables, crafting materials and valuables (no guaranteed weapon case) — best opened during a Night Raid for the loot bump. Verdict: a cheap, common, low-effort key — grab the room as a bonus stop when you're already in Medical Research, ideally at night.
What is the Medical Storage Key in ARC Raiders?
The Medical Storage Key is one of Stella Montis's map-specific access keys — consumable items that open a single sealed door, then vanish from your inventory. Per the official wiki it "unlocks a door in Medical Research in Stella Montis" and was added in patch 1.2.0 (arcraiders.wiki).
Here are the verified item-card stats:
| Property | Value |
|---|---|
| Rarity | Uncommon (green) |
| Type | Single-use access key (consumed on use) |
| Weight | 0.25 |
| Vendor value | 100 Coins |
| Stack size | 1 |
| Map | Stella Montis |
| Unlocks | The Medical Storage room in Medical Research |
| Source | Scavenging |
The headline detail is the rarity: this is an Uncommon key, not a Rare one, so it drops far more often and costs almost nothing to hold at 0.25 weight. That availability is the whole appeal — you'll stumble into this key naturally while clearing interiors, and on Stella Montis even a modest medical room is worth a 30-second detour.
If you're clearing the Stella Montis keyring, this pairs with the Stella Montis Archives Key and the Stella Montis Assembly Admin Key — same endgame map, same "find the key, find the door" loop. For the full lay of the land, see our Stella Montis guide.
How do you get the Medical Storage Key?
The key comes only from scavenging — there's no quest hand-out (arcraiders.wiki). Like every key in ARC Raiders it's a random drop, so you can't farm a guaranteed route — but you can stack the odds:
- Search residential interiors and living quarters. Keys have their highest drop rates in desks, drawers, cabinets and medical furniture, and the more searchable rooms you clear, the more keys you see over time (levelupper). Amber/orange residential zones are dense with this kind of furniture.
- You don't have to be on Stella Montis to find it. Keys aren't locked to the map they open — one writer pulled the Medical Storage Key from the Ruby Residence building on Dam Battlegrounds, and flags the upper floors of the Research and Administration building there as frequent key spawns (destructoid). Farm keys on a safer map, cash them in on Stella Montis.
- Take it off other players. On a PvP-heavy endgame map, keys also drop from Raiders you down — checking bodies is free key supply (levelupper).
- Keep it in your safe pocket. Stella Montis kills you fast — a key in your safe pocket survives a death, so never carry your only key in your main inventory.
Where is the Medical Storage door in ARC Raiders?
The Medical Storage door is inside the Medical Research zone, and the single most important thing to know is that it's not on the main floor — it's down the stairs. From Assembly, "take the corridor that leads to Medical Research, and use any of the stairs to go down," and the room is along the lower level near one of the zone's entrances (destructoid). Deltia's Gaming describes the same thing from the other direction — the door is across a stairwell once you're down in the medical labs (deltiasgaming). The annotated map up top marks Medical Research and the exact door.
A few practical notes for finding it:
- Look for the red indicator lights. The locked door is marked with red lights, the standard ARC tell for a key-gated room (levelupper). Sources differ on the exact corner — Dualshockers points to the north side of Medical Research, others to the southwest — so use the stairs-down + red-lights combination plus the map marker rather than a single compass heading (dualshockers).
- Don't get baited by the fuel-cell doors. Medical Research has several doors that look like they need a fuel cell — the Medical Storage room is not one of them; this key alone opens it (levelupper).
- Close the door behind you. The room is open and unprotected — anyone can wander in while you loot. Shut the door once you're inside so you don't get pushed mid-clear (levelupper).
What's behind the door — the loot breakdown
The honest caveat first: like every locked room in ARC Raiders, the exact contents are randomized — anyone promising a guaranteed weapon is guessing. The Medical Storage room is small and quick to clear, and because it's a medical store, the loot skews toward consumables and materials rather than a big weapon case. Here's the cross-verified profile:
| Loot category | What turns up | Notes |
|---|---|---|
| Medical consumables | Healing items and medical sprays | The room's bread-and-butter — it's a medical store |
| Crafting materials | Components and resources | Reliable mid-value pulls |
| Valuables | Sellable trade goods | Coins-per-weight filler |
| Occasional keys | Extra access keys | RNG bonus, not guaranteed |
| Gear / weapons | The occasional weapon or piece of gear | Possible but not a guaranteed weapon case |
Sources: levelupper, deltiasgaming, dualshockers. Deltia's run describes "a wide range of high-value loot, including materials, weapons, healing items" (deltiasgaming), while LevelUpper is blunt that "there are no guaranteed weapon cases and no guaranteed high-tier drops — some runs feel decent, others feel very underwhelming" (levelupper). Both are true: it's a solid, low-effort grab, not a guaranteed payday.
Open it during a Night Raid if you can. Night Raids roll higher-value loot across the whole map, locked rooms included — so burning a single-use key like this in a daytime raid leaves value on the table (levelupper).
If grinding Stella Montis for materials and meds sounds like a lot of RNG and risk — because it is — that's exactly the grind we shortcut:
Skip the key grind, get the gear directly:
- ARC Raiders Materials — from $0.02 — every rarity, instant delivery, trusted.
- ARC Raiders Blueprints — from $0.99 — 60+ blueprints, unlock rare weapons, fast & secure delivery.
- All ARC Raiders services — everything topside, without the RNG.
Is the Medical Storage Key worth it?
Yes — as a bonus stop, not a destination. It's only Uncommon, so you'll find it far more often than Stella Montis's Rare keys, and at 0.25 weight it costs nothing to carry. The room is small, fast, and reliably hands you medical consumables, crafting materials and valuables, with the occasional key or piece of gear on top. For a key this cheap and common, clearing it whenever you're already in Medical Research is free value.
Just don't go out of your way for it. The loot ceiling is limited — there's no guaranteed weapon case — so this isn't a key you build a whole run around the way you might for a Rare vault. Treat it as a 30-second detour during a Night Raid when you're passing through Medical Research, close the door behind you, loot fast, and have an extract picked before you commit. On the deadliest map in the game, a cheap key that pays for itself is exactly what you want.

FAQ
Where do you use the Stella Montis Medical Storage Key? On the locked Medical Storage door inside the Medical Research zone on Stella Montis. It's on the lower level — take the stairs down from the corridor that connects Medical Research to Assembly, and look for the locked door with red indicator lights. Several nearby medical doors look like they need a fuel cell, but the Medical Storage room only needs this key.
How do you get the Medical Storage Key? Only from scavenging — there's no quest reward. It's a random drop, with the best odds in residential interiors, desks, drawers and medical furniture. Keys aren't locked to their map, so you can farm one on a safer map (Dam Battlegrounds residential blocks are a strong spot) and use it on Stella Montis. You can also loot keys off downed players.
Is the Medical Storage Key single-use? Yes. It's consumed the moment you open the door, so one key equals one entry. If you die before using it, it's lost with the rest of your carried gear — keep it in a safe pocket so it survives a death.
What loot is in the Medical Storage room? Randomized loot in a small, quick-to-clear room: medical consumables and healing items, crafting materials, valuables, and the occasional extra key — plus a chance at a weapon or piece of gear. There is no guaranteed weapon case, so expect a steady materials-and-meds haul rather than a jackpot.
Should I open it during a Night Raid? Ideally, yes. Night Raids roll higher-value loot across the map, including locked rooms, so a single-use key returns more at night. Opening it during a daytime raid still works but leaves value on the table.
Is the Medical Storage Key worth using? For a cheap, common Uncommon key, it's an easy yes as a bonus stop — clear it whenever you're already in Medical Research. It's not worth a dedicated run, though: the loot ceiling is limited and there's no guaranteed high-tier drop. Go solo, close the door behind you, loot fast, and extract.
