What is the Red Keycard?
Unlike Green or Blue cards, Red cards cannot be purchased. They must be earned through completing Blue puzzle monuments.
How to Get a Red Keycard
1. Airfield Route
Airfield is one of the most common ways to secure a Red card.
- Bring: 2× Fuses, 1× Green Keycard, 1× Blue Keycard
- Insert the first Fuse and swipe Green to access the initial room
- Power up the second fuse box
- Swipe Blue to reach the control tower room
- Loot the Red Keycard from the desk
2. Power Plant Route
Power Plant offers another way to farm Reds.
- Bring: 2× Fuses, 1× Green, 1× Blue
- Flip multiple switches to power different buildings
- Insert Fuses into designated fuse boxes
- Use Green first, then Blue for the final room
- Loot the Red card upstairs in the main building
This route is complex and spread out, so bring teammates to split tasks.
3. Trainyard Route
Trainyard is slightly easier than Airfield or Power Plant.
- Bring: 2× Fuses, 1× Green, 1× Blue
- Insert a Fuse into the box by the main building
- Swipe Green to gain access
- Insert the second Fuse deeper inside
- Swipe Blue in the control room
- Loot the Red Keycard
4. Water Treatment Plant Route
One of the simplest ways to farm Reds.
- Bring: 1× Fuse, 1× Blue Keycard
- Insert Fuse in the power building
- Swipe Blue at the puzzle door
- Loot the Red Keycard from the desk
Where Red Keycards Are Used
Once you've got one, Red Keycards unlock:
- Launch Site — the most profitable monument in Rust
- Military Tunnels — full of Scientists and elite crates
- Oil Rigs (Small & Large) — Red rooms with locked loot
- Underwater Labs — restricted Red sections
These are always high-risk, high-reward areas. Go prepared. For a full breakdown of what's inside each monument, see our Red Keycard Locations & Uses guide.
Tips for Farming Red Cards
- Bring extra Fuses. Most Red routes require two.
- Coordinate with teammates. Multi-stage puzzles are much easier with a group.
- Expect PvP. Airfield and Power Plant are notorious hotspots.
- Don't waste durability. With only 2 swipes per card, use Reds only when you're ready for a full monument run.
- Farm Water Treatment solo. It's the simplest Red card farm if you already have Blue.
