Subnautica Cabin 1 Code — 1869 and Every Aurora Door Code

The code for Cabin 1 on the Aurora is 1869. It's found on the "Sweet Offer" PDA in the ship's Locker Room, which you reach by cutting through a sealed door with the Laser Cutter. Cabin 1 is a crew cabin in the Living Quarters — a different room from the Captain's Quarters (code 2679), which is the one people usually mean when they search for "the code to the captain's cabin." This guide gives you the exact location of the 1869 PDA, what's inside Cabin 1 once you unlock it, and the full table of all four Aurora door codes so you never swim back for a second trip.

Here's what you'll learn:

• The Cabin 1 code and where the PDA is found
• What's actually inside Cabin 1 (and whether it's worth the detour)
• The difference between Cabin 1 and the Captain's Quarters
• Every Aurora door code in one table
• The gear you need to reach the Locker Room at all

The Cabin 1 Code: 1869

Cabin 1 is locked with the code 1869. You do not get it from a radio message or a databox — it's written in a PDA you pick up on the ship:

1. Board the Aurora (post-explosion, with a Radiation Suit — the full checklist is in our Aurora codes guide).
2. Reach the Locker Room in the quad-junction hallway below the cargo elevator.
3. The Locker Room door is sealed — open it with the Laser Cutter (fragment locations are in our laser cutter guide).
4. Pick up the PDA "Sweet Offer" — a message from the Prawn Bay crew that ends: "Come by Cabin no.1. Code's 1869."

Per the official Subnautica Wiki: "Cabin 1 is locked by a code, which is '1869', found in the Abandoned PDA named 'Sweet Offer'."

What's Inside Cabin 1?

Honestly? Not much — Cabin 1 is a small crew cabin, and its loot is:

• A Blue Cap (cosmetic headwear)
• An Arcade Gorge Toy (a collectible from the game Natural Selection 2)
• The PDA "Responsible Autonomous Relationships" (lore)

The code is more valuable as a milestone than the room's contents: it confirms you've cleared the Locker Room and unlocks the achievement-relevant exploration of the Living Quarters. If you're hunting for meaningful loot, the ship's real prizes — the Cyclops Engine Efficiency Module, Prawn Suit fragments and the Neptune rocket blueprint — are covered in our Aurora codes guide, which maps every room and reward on the ship.

Cabin 1 vs Captain's Quarters (Don't Mix Them Up)

This is the confusion behind most "cabin 1 code" searches:

If you're looking for the code that ends the game, you want 2679 and the drive core repair, not 1869.

1869. It opens Cabin 1 in the Aurora's Living Quarters.

Where do I find the 1869 code?

On the "Sweet Offer" PDA in the Aurora's Locker Room, behind a sealed door you open with the Laser Cutter. The PDA is written by Prawn Bay crew and explicitly ends with "Code's 1869."

Is Cabin 1 the same as the Captain's Quarters?

A Blue Cap, an Arcade Gorge Toy and the "Responsible Autonomous Relationships" PDA. It's a lore room, not a loot room.

1454 (Cargo Bay), 1869 (Cabin 1), 6483 (Laboratory) and 2679 (Captain's Quarters). The first three come from PDAs on the ship; 2679 arrives via radio.
