Secrets, riddles and puzzles in Honkai: Star Rail
How to open a locked door in the base zone
At the start of the corridor, the eastern building in the base zone appears blocked. When attempting to access the console, a message reads: “You Have Other Things to Do.”
To unlock this door, continue the story until the main control zone reveals an optional activity symbol. Arlan will be waiting there with a small side quest called Birth Again Way. Speak with him to trigger the side mission.
Return to the base zone and speak with Abraham, the man standing before the closed door. After the dialogue, interact with the console to open the door.
Proceed into the hallway and move a short distance forward. On the right, the same door awaits; it will require three key cards to open.
How to get the first key
The first access key lies in the rear room of the eastern compartment. Advance through the corridor, defeat a group of monsters, then enter the room and confront a tougher enemy. It helps to level up the available heroes to their maximum before the confrontation.
When the foe falls, the key automatically drops into the player’s inventory.
How to get a second key
Use fast travel to reach the Main Control Zone and locate the man with thick hair, situated to the right of the local merchant.
Talking to him yields several responses. Engage in conversation five times in a row, choosing any responses. On the fifth interaction, he rewards the second access key.
How to get the third key
The final key is found by exploring the western portion of the first floor in the storage area. There, a simple riddle involving switchable bridges must be solved, a topic already covered in a separate guide.
If the challenge feels tricky:
- Enter the compartment and descend. Defeat the monsters, then interact with the console.
- A bridge appears. Cross it and fight the second wave of enemies.
- Immediately afterward, activate two consoles: one beside the defeated foes and the second behind the crates on the higher platform.
- Return to the console above and interact with it. A bridge appears, letting access to the top compartment where the key card is located. A deluxe box is nearby.
Backtrack to the console in the eastern building of the Base Zone and use all three key cards to unlock the final chamber.
The room contains a deluxe box. Clearing a large group of void rangers is required to claim it, and there are notes in the area worth collecting.
