    StarRupture: All 3 Redleaf Keycard Locations Guide

    By Kirthana KJanuary 7, 2026Updated:January 8, 20264 Mins Read

    Key Points

    • The CRFHSRB Redleaf Keycards help you unlock the CRFHSRB Redleaf Abandoned Base.
    • There are three keycards to find near the abandoned base
    • These areas are also swarming with enemies, so you need to plan your route accordingly.

    During your exploration in StarRupture, it is quite common to encounter abandoned bases that require an item to access them. Such is the case with the CRFHSRB Redleaf Abandoned Base, which requires three keycards to unlock it. Once you do, you get to uncover the secret treasure within. 

    StarRupture – CRFHSRB Redleaf Abandoned Base Location

    You need to travel all the way to the northeastern section of the map to find an abandoned satellite base. The base is clearly visible once you reach the area, you can’t miss it. Once you find it, it is recommended to set up an outpost here to make it easy to access the area again.

    The three keycards you need to find are

    • Eng. Perkins’s Security Clearance Card
    • Dr. Ellis’s Security Clearance Card
    • Dr. Diaz’s Security Clearance Card

    You will also need an additional Redleaf Override Access Card to access one of the card rooms. Let’s start by collecting this one to access the red building, which will help us get the first blue keycard.

    You will find this card at s: H4, x: 3906, y: 1946. Make your way to the central area until you spot a large red building. Scale this building and make your way to the top to get the Redleaf Override Access keycard off a dead body.

    You need to find another red building to use the Redleaf Override Access Card and collect your first blue card. If you look towards the north from the vantage point of your previous location, you will spot a small red building. Make your way over there and unlock it, then check the table to get Dr. Ellis’s Security Clearance Card.

    Dr. Diaz’s Security Clearance Card Location

    Exit the building you were in and take the stairs on your left. Keep to your left while sprinting, but be careful, you will spot a Goliath here. You could run past while sticking to your left to find the first blue building. Enter it, then take the ladder to the second floor. You will find Dr. Diaz’s Security Clearance Card on the table.

    You now need to make your way far west to find the final keycard. Keep crossing the terrain and you will eventually spot the blue building containing the Eng. Perkins’s Security Clearance Card. It is found right on the table as soon as you enter the building.

    What’s Inside the Redleaf Abandoned Base

    To find and enter the Redleaf Abadoned Base, first, scale the red building beside it to get up to the top floor, then jump towards the blue building. Unlock the door to the building, then go up to find another locked door. 

    Right beside it are three slots to place the three keycards. This will unlock the room beyond the door. Investigate the storage box here to get the following:

    • 1x Turbine – Blueprint
    • 60x War Bonds
    • 1x Electromagnetic Coil – Blueprint
    • 1x Hardening Agent – Blueprint
    • 1x Valve – Blueprint
    • 1x Frame Memory Module
