What are the Aurora door codes in Subnautica?

1454 opens the Cargo Bay, 1869 opens Cabin No. 1, 6483 opens Lab Access, and 2679 opens the Captain's Quarters. These codes are fixed and identical in every save, so you can enter them right away. The 6666 Robotics Bay code exists in lore but the room was cut, so it does nothing.

Are the Aurora codes the same in every game?

Yes. The Aurora keypad codes are fixed — they don't change between saves or players — so you can punch them in without finding the in-game PDA clues first. Each door only needs the code entered once and then stays open.

What is the code for the Captain's Quarters in Subnautica?

2679. Unlike the other doors, you normally receive this code through a radio message as part of the main story rather than from a found PDA, but it works as soon as you have it.

Subnautica Aurora Door Codes

The Aurora's locked doors hide upgrades, story, and a Cyclops engine component, and the keypad codes are fixed in every game, so you don't have to hunt the PDAs first. Here are all four working codes, what each opens, where the in-game clues are, and the one code that does nothing.

Every Code & What It Opens

Code	Opens	What's inside	Clue (PDA)
1454	Cargo Bay	Three supply crates — can include a Cyclops Engine component	"Notes to self" data download, in the Administration office
1869	Cabin No. 1	Living quarters — Blue Cap, arcade toy, décor	"Sweet Offer" data download
6483	Lab Access	Two doors — sample flasks, Microscope, Sample Analyzer, supply crates	"Lab Access" data download, near the Prawn Suit Bay
2679	Captain's Quarters	Aurora Miniature + Aurora poster décor	Delivered by radio message in the main story (not a found PDA)

You don't need the clues. The codes are identical in every game, so you can enter them straight away. Each door only takes the code once. After that it stays open for the rest of your save.

About "6666" / the Robotics Bay: you'll see a 6666 code referenced, but the Robotics Bay was cut during development and the room is permanently inaccessible. The code does nothing in the finished game. Don't waste time hunting for that door.

Before You Go In

Fix the drive core first. The Aurora is irradiated until you repair the drive core: bring a Radiation Suit (and a Repair Tool) or you'll take radiation damage the whole time.
The open-world wrecks don't use codes. Only the Aurora has keypad doors. Out in the biomes, sealed wreck doors are opened with the Laser Cutter, not a code, so if a wreck door won't take a number, that's why.
