Discover where they are hidden and memorize all keycard locations in Rust.
Getting your hands on keycards when exploring Rust is like finding the golden ticket to the game’s loot room. From secret rooms filled with weapons and supplies to areas only accessible with the right color card, keycards open doors, literally and figuratively helping you progress quickly.
But finding all keycards in Rust can be tricky, especially when you’re racing against other players eager for the same treasure. This guide will cover every spot where you can find these prized keycards, along with a few tips on what to expect once you swipe in.
What are Keycards in Rust?
Keycards in Rust are essential items that open up new areas packed with valuable loot and scrap. They come in three colors: green, blue, and red—each representing a different level of access and reward.
Green keycards are the easiest to find and work as basic entry passes, often located through simple looting or trades.
Blue keycards step things up, sometimes found in surprising places like inside fish when you gut them.
Red keycards, though, are the rarest and most powerful, with very limited uses and tough-to-reach locations.
If you’re a beginner, finding them in such a hostile world can be next to impossible. So to help you progress much faster, below are all keycard locations in Rust
Green Card Locations

• Junkyard
Head to the office room above the bridge, where a green keycard sits on a desk. Watch out for other players around, especially those recycling at the highest points, or try using the magnet crane.
• Lighthouse
Check the office room at the base of the tower, just to the right. Keep an eye out—players can easily spot you from above and may be waiting to ambush you.
• Supermarket
The back room of the supermarket, on the desk to the left, has a green keycard. This spot is relatively safe and straightforward to get in and out of without much trouble.
• Underwater Labs
In these randomly generated underwater modules, green keycards can be found on the floor or on workbenches. Look for a module with lockers surrounding a central computer room. In front of the lockers, you may spot a card on the floor, or check the green-and-blue puzzle room for one sitting on a workbench.
• Small Oil Rig
You’ll need to get past scientists and reach the highest level. Behind a blue puzzle door, accessible with a blue keycard, a green keycard lies on a table. Be careful—scientists may be lurking near the door.
• Large Oil Rig
Use an existing green keycard to unlock a green puzzle door. Inside, you’ll find another green card on the desk to the right.
Blue Card Locations

• Satellite
To grab a blue keycard, head to the satellite monument. You’ll need a green keycard and an electric fuse. Find the small shed near the satellite dish, open the power room, insert the fuse, and flip the switch. Then, use your green keycard on the door to enter the puzzle room and collect the blue keycard.
• Harbor
The harbor has two puzzle rooms with blue keycards. At the small harbor, locate the two-story container building, insert a fuse at the bottom, and use your green keycard to access the locked room upstairs. The blue card is waiting for you on a table. For the large harbor layout, go to the central area, find the small shed for the fuse, and follow the same steps to get your blue keycard.
• Sewer Branch
In the underground tunnels, start at the main power building to find the fuse and switch. Go underground, use your green keycard to enter the puzzle room, and check the central table for the blue keycard.
• Water Treatment
At the water treatment plant, find the fuse box in the metal shed. After activating it, run to the smaller shed by the red building, where you’ll find your blue keycard waiting on the desk.

Red Card Locations

• Airfield
Start by locating the fuse box in the office building, then insert your fuse and activate the timer. Head to the tunnels by the hangars and take the left path. Use a green card to enter the first room, find a second fuse box, and then swipe your blue keycard to access the final loot room. The red keycard will be on the desk inside.
• Power Plant
At the large main building, you’ll need one green card, one blue card, and a fuse. Start by flipping a switch in the three-story red building, then head to a smaller red building with a slanted roof for a second switch. Once you’re in the main building, swipe a green card to enter, then flip one last switch on the first floor. Finally, swipe your blue card in the room upstairs for access to the red keycard on the desk.
• Train Yard
Activate the first switch in the three-story metal shed, but beware of scientists. Next, go to the large tower for a second switch at the top. After that, head to the central puzzle building, place a fuse and flip the switch on the first floor. You can use a green card for entry or opt for the blue door to reach the red keycard.
• Arctic Base
At the Arctic Base, be prepared for a fight with Arctic scientists. Locate the left garage, and swipe your blue card on the powered door. Once inside, head to the back for the red keycard.
