Rust Keycard Guide — Green, Blue & Red (2026)
Where each colour drops, what each unlocks, and the progression chain that takes a single barrel-found green card to Launch Site loot in 90 minutes.
Green → Blue → Red. Each puzzle hands you the next card.
Find a Green card from a barrel or low-tier monument. Use it at a Tier 1 puzzle (e.g. Sewer Branch) — the loot room contains a Blue card. Take the Blue card to a Tier 2 monument (e.g. Airfield) — that puzzle drops a Red card. The Red card opens Tier 3 monuments (Launch Site, Military Tunnels, Missile Silo). One green card chains all the way up.
Where each card drops
| Card | Primary sources | Time to acquire |
|---|---|---|
| 🟢 Green | Mining Outpost · Abandoned Supermarket · Lighthouse · Oxum's Gas Station · Junkyard scientist drop · basic crates & barrels | ~15-30 min from spawn |
| 🔵 Blue | Tier 1 puzzle reward: Sewer Branch · Satellite Dish · Small Harbor · Large Harbor · The Dome · Cargo Ship | ~30-45 min after green card |
| 🔴 Red | Tier 2 puzzle reward: Airfield · Power Plant · Trainyard · Water Treatment · Patrol Heli crate · Bradley crate · Cargo Ship locked crate | ~30-60 min after blue card |

The classic 90-minute progression chain
| Step | Action | Result |

| 1 | Loot a barrel or hit Mining Outpost | Green card (~15-20 min from spawn) |
| 2 | Run Sewer Branch with green card + 1 fuse | Blue card + components |

Total time: ~90 minutes for a clean run. Bring meds and at least basic clothing — Tier 2 and 3 monuments have scientist NPCs and radiation.
Frequently asked questions
How do I get a green keycard in Rust?
Green keycards drop from low-tier monuments and barrels: Mining Outpost, Abandoned Supermarket, Lighthouse, Oxum's Gas Station, the Junkyard scientist, and many basic crates. They're the easiest to find — typically you'll have a green card within 30 minutes of starting a wipe.
How do I get a blue keycard?
Blue keycards are the puzzle reward at most Tier 1 (green-card) monuments: Sewer Branch, Satellite Dish, Small Harbor, Large Harbor and The Dome. Use a green card at the puzzle door, claim the Blue Keycard from the loot room. Blue cards also drop from Cargo Ship and rarely from elite crates.
How do I get a red keycard?
Red keycards are the puzzle reward at Tier 2 (blue-card) monuments: Airfield, Power Plant, Trainyard, Water Treatment Plant. Use blue card → claim red. Red cards also drop from the Bradley Tank crates at Launch Site, Patrol Helicopter crates, and Cargo Ship's locked crate (after a 15-min hack timer).
Do keycards expire or get used up?
Keycards are consumed on use — each puzzle door swipe uses one card. They don't expire while you hold them, so stock up before a serious monument route. Some servers reset keycard inventory on map wipe; on most servers you keep them through wipe.
Can I just buy keycards from a vending machine?
Sometimes. Outpost vending machines occasionally sell green keycards for ~30-50 scrap, and player-set vending machines around bases sometimes sell green/blue cards. Red keycards are rarely sold and usually overpriced. Farming them yourself is faster mid-wipe.
What's the fastest progression path?
Green card → Sewer Branch (Blue card reward) → Airfield (Red card reward) → Launch Site / Military Tunnels (top-tier loot). One green card from a barrel can chain you to top-tier loot in 90 minutes if you know the puzzle order. Full route in our Monuments hub.
