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.
| 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) |
