All Blue Keycard Locations in Rust (2026)
1. Harbor (Both Layouts)
Location: On the desk inside the powered office.
- Insert a Fuse in the office fuse box
- Flip the power switch
- Swipe your Green card at the reader
- Loot the Blue card from the desk inside
Note: Easy to run but usually high traffic, especially early wipe.
2. Satellite Dish
Location: On the desk inside the second powered container.
- Insert a Fuse into the first container and flip the switch
- Run across to the second container with the Green card door
- Swipe Green to access the room
- Collect the Blue Keycard from the desk
Warning: Quick puzzle but very exposed to snipers and roof campers.
3. Sewer Branch
Location: On the desk inside the underground tunnel puzzle room.
- Insert a Fuse into the box near the recycler
- Flip the switch to power the tunnels
- Enter the underground section
- Swipe the Green card at the locked door
- Loot the Blue card inside
More complex but safer, as fewer players contest Sewer compared to Harbor or Satellite.
Buying Blue Keycards at Outpost
If you'd rather not risk PvP, Blue cards are available at Outpost.
- Vendor: Tools vending machine
- Price: 100 scrap
- Benefit: Guaranteed access, no PvP risk
- Downside: Costly if you're still early in the wipe
Which Location is Best?
- Harbor: Fastest method, but crowded.
- Satellite Dish: Good speed, but high PvP risk.
- Sewer Branch: Longer run, but often uncontested.
- Outpost Purchase: The safest method if you have scrap to spare.
Respawn Timers
- Blue Keycards generally respawn every 20–30 minutes after being looted.
- If the card isn't there, someone got to it first. Make a note of the time and rotate back later.
Pro Tips for Farming Blue Cards
- Always bring at least one Fuse when running monuments. Most puzzles won't work without it.
- Use team coordination. Have one player insert the Fuse while others hold the area.
- Run puzzles at off-peak hours if possible to avoid ambushes.
- Stack multiple Green cards so you can run several Blue puzzles back-to-back.
Frequently Asked Questions
Three main monument routes: Harbor, Satellite, and Sewer Branch.
No. They only spawn on desks in puzzle rooms or can be purchased at Outpost.
Yes, provided the monument timer has reset (about 20–30 minutes).
Sewer Branch is usually the safest option, though it takes longer.
