Blue Keycard

The Blue Keycard is a medium-level clearance door key. The following monuments have doors that require the blue keycard:

  • Airfield
  • Military Tunnels
  • Powerplant
  • Trainyard
  • Water Treatment

You can collect a blue keycard from several points of interest. Namely, either of the Harbours, Sewer Branches, and Satellite Dish locations.

Typically, you can find blue keycards on a table in the rooms that require the Green Keycard for entry.

To both retrieve and utilize a blue keycard, you will also need Electric Fuses.

The locked doors at points of interest do not have power, with each card reader being attached to a fuse box, usually a short distance away from the door itself.

Once you insert an electric fuse into the fusebox, you will have a limited amount of time to make it to the door and swipe the blue keycard.

Each blue keycard has a limited amount of uses and will decrease its overall health each time you swipe it through a card reader.

If you’re struggling to find a blue keycard or wish to skip the green keycard puzzles, you can purchase a blue keycard from an Outpost vending machine <Tools and Stuff> for 100 scrap pieces.

Alternatively, you can sell any unwanted blue keycards to the Bandit Camp Shopkeeper for 40 scrap pieces if you have no interest in running the monuments.
