A Class A Hacked Keycard is used to unlock doors that require it. Upon unlocking a door, one keycard is consumed and the door is permanently unlocked (it can still be closed).
Class A is the least common of the three hacked keycard classes, in terms of both availability and use. Except for one class A in the MPO Prison and one in the Solar Casino, hacked keycard spawns are random. They are usually found in desks and occasionally in bathroom shelves.
Some non-random doors are locked by class A cards:
- MPO Prison F01: The door that leads to F00. A class A card can always be found in the nearby room.
- Central Control: The door near the generator room; contains all three recharging stations.
- Solar Casino: The door that hides the Level 2 Mine Data Chip. The room with the door should have a class A keycard in a desk.
- Murray Space Center: The room with the oxygen generator in the northwest and a storage room in the southwest. Both rooms have two independently A-locked doors, so 4 class A locks in total.
Randomly generated rooms can also contain doors that require a class A card. However, these rooms are always dead-ends that usually contain some useful items, so a hacked keycard is never required in a randomly generated floor.
