Locating the Underground Bunker in Episode 4

The journey to the Dark Room leads Max and Chloe to the old Prescott barn located in Arcadia Bay. Inside the barn, players must solve a environmental puzzle involving a hidden trapdoor concealed beneath the floorboards. Once you lower the latch and descend the staircase, you will encounter the locked metal door equipped with a digital keypad.

For players searching for a quick solution, the direct key code to open the vault door is 542. Entering this combination immediately grants access to the dark interior without requiring further clue gathering. However, understanding how the game presents this solution adds valuable context to the ongoing investigation.

How to Find the Keypad Combination

Players who prefer solving the mystery organically can discover the combination through clues gathered earlier in the episode. During the investigation phase, inspecting Nathan Prescott's personal belongings reveals a slip of paper covered in scribbled numbers. Among these sequences, the red underlined three-digit code 542 stands out as the primary clue.

Additionally, examining the physical keypad itself provides a subtle visual cue for observant players. Looking closely at the buttons reveals that the numbers 2, 4, and 5 show significantly more physical wear than the rest. If you want to review full walkthroughs, check out the for complete details.

Unlocking the Dark Room Door

To enter the code, simply interact with the keypad next to the locked metal vault door. Press the digits 5, 4, and 2 in exact order to disengage the locking mechanism. Once entered correctly, the heavy door swings open, allowing Max and Chloe to explore the hidden photographic studio.

Inside the facility, players will uncover crucial evidence that ties together several mysteries surrounding Arcadia Bay. The area contains victim files, photographic equipment, and chilling documents detailing the bunker's construction. Reaching this area marks a point of no return for the episode's dramatic climax.

Troubleshooting Common Keypad Issues

Some players occasionally experience confusion due to input errors or visual glitches on the keypad screen. If the combination does not work immediately, step back from the keypad interface and re-interact with the prompt. Ensure that you press the numbers in the precise order of 5, 4, and 2.

It is also worth noting that the bunker keypad code remains identical across all standard gaming platforms and remasters. Unlike Nathan's phone PIN, which can vary depending on previous player choices, the vault lock never changes. Entering 542 will always successfully grant entry to the Dark Room.
