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 interact with the console, the message emerges: You Have Other Things to Do.
To bypass this door, continue a bit along the story until an additional activity icon appears in the main control area. A character named Arlan offers a small side quest. Engaging with him triggers the mission Birth Again Way.
Return to the base zone and speak with Abraham, who stands before the closed door. After the dialogue, interact with the console to gain access.
Proceed down the hallway and advance a little. On the right, a second locked door awaits, guarded by the need for three key cards.
How to get the first key
The initial key is tucked away in the back room of the eastern compartment. Move forward, clear a pack of enemies in the hallway, then enter the room and defeat a tougher foe. It helps to ensure the heroes are leveled up to their maximum capability before tackling this challenge.
Defeating the adversary causes the key to drop directly into the player’s inventory.
How to get a second key
Use the fast travel option to reach the Main Control Zone and locate the man with thick hair. He stands to the right of the local merchant.
When spoken to, a set of responses appears. Talk to him five times in a row, and select any answers. On the fifth interaction, the second access key is granted.
How to get the third key
The final key is found by inspecting the western section of the first floor in the storage area. A simple riddle involving switchable bridges must be solved, a puzzle already explored in a separate guide.
If the task proves tricky:
- Enter the compartment and descend. Defeat the monsters, then interact with the console.
- A bridge appears. Cross it and battle the second group of enemies.
- Immediately afterward, activate two consoles: one beside the defeated enemies and the other behind the crates on the elevated platform.
- Return to the console above and interact with it. A bridge will emerge, revealing a path to the top compartment and the key card. A deluxe box awaits there as well.
Return to the controller in the eastern building of the Base Zone and use all three key cards found.
The room housing the deluxe box is guarded by a large crowd of void rangers. Noting can also be collected here.
