The Aurora Cargo Bay 3 code in Subnautica is 1454. It opens the locked cargo-bay door, but typing four digits is only one part of a successful Aurora trip: fire, blocked routes and an unprepared inventory can still send you back to the Lifepod empty-handed.
Key points
- Cargo Bay 3’s fixed code is 1454.
- The Administration PDA records the relevant in-game clue.
- 2679 is for the Captain’s Quarters, not Cargo Bay 3.
- A Fire Extinguisher is essential and a Propulsion Cannon is strongly recommended.
Bring supplies before you approach the wreck. The Aurora is an interior exploration run, not a quick pickup, and leaving several inventory slots open matters. More practical reading is available in our articles, news section and latest posts.
Quick answer
Enter 1454 at the keypad marked for Cargo Bay 3. First visit Administration at the entrance junction and collect its PDA; that is the clean in-game way to record the clue in your PDA. The keypad is inside the Aurora, not on the exterior hull.
Key points
- Cargo Bay 3 uses the fixed code 1454.
- Pick up the Administration PDA first so the clue is in your log.
- A Fire Extinguisher is essential for burning corridors.
- A Propulsion Cannon prevents crate barriers from ending the route.
- Bring a Laser Cutter if you want to deal with sealed access points farther in.
- Radio code 2679 is for the Captain’s Quarters, not Cargo Bay 3.
Code table
| Aurora access point | Code | What it is not |
|---|---|---|
| Cargo Bay 3 | 1454 | The cargo-bay door near the entry route |
| Cabin 1 | 1869 | Crew quarters access |
| Laboratory | 6483 | A separate interior door |
| Captain’s Quarters | 2679 | The radio-delivered code |
The codes are fixed, but the keypad matters. If 1454 does not open a door, read the nearby sector sign before assuming the game is broken: you are likely at a different locked room.
How to use the codes
Enter the Aurora through its accessible breach and follow the signs to the first junction. Administration is worth the short detour before heading toward Cargo Bay 3 because it supplies the PDA clue and confirms that you are following the right route.
- Craft a Fire Extinguisher and a Repair Tool. Take food and water, plus a Propulsion Cannon if you have one.
- Reach the Aurora’s accessible entry while staying alert around the wreck.
- Put out the fires blocking the corridor. Aim at the base and advance a short section at a time instead of emptying the extinguisher blindly.
- At the junction, search Administration and take the PDA. Check your PDA’s downloaded data if you want to verify the clue.
- Follow the signs to Cargo Bay 3 and use the Propulsion Cannon on obstructing crates.
- Use the correct door keypad and enter 1454.
- Loot deliberately, then reassess health, food and tools before going deeper.
On controller, stand close enough for the interaction prompt to appear. A common mistake is entering the right number at the wrong panel. The Cargo Bay 3 sign is the reliable reference; the outer hull position is not.
Equipment to pack before opening Cargo Bay 3
The code opens a door, not the full Aurora. The Fire Extinguisher is the immediate priority, while the Repair Tool covers damaged equipment you encounter. The Propulsion Cannon is the route-saving tool because it clears cargo crates that can block ramps and corridors.
| Item | Priority | Use on the Aurora |
|---|---|---|
| Fire Extinguisher | Essential | Cross burning corridors. |
| Repair Tool | Strongly recommended | Handle repairable equipment. |
| Propulsion Cannon | Recommended | Move crates and keep the route open. |
| Laser Cutter | Bring if available | Open some sealed access points. |
| Seaglide | Convenience | Speed up approach and retreat. |
Common mistakes
The usual wrong answer is 2679. It is an Aurora code, but for the Captain’s Quarters; it will not open Cargo Bay 3. Read the sector sign first.
The second mistake is bringing the code but not the equipment. Fire can stop you long before the cargo bay and crates can block later progress. The third is carrying a full mineral inventory. Store resources first, leave four to six slots free and prioritise unique pickups.
The official Subnautica support answer confirms that Aurora door codes are found through the PDA. Steam’s official Subnautica page also frames exploration around resource management and crafted equipment.
