Sinking City 2 Apartment 5 Safe Code & Loot

In The Sinking City 2, the safe inside Apartment 5 (found during the main story mission in the flooded Oakmont residential district) opens with the code 9-4-7. Inside you’ll find a handful of useful supplies: a Medical Syringe, a box of 9mm ammunition, and a piece of lore collectible — a torn diary page that hints at the apartment owner’s fate.

Formula

The number of possible combinations for a numeric safe lock is simply 10^c, where c is the number of digits in the code. Each dial position has 10 possible digits (0–9), so for a 3-digit code that’s 10 × 10 × 10 = 1,000 combinations. The time to try all combinations is that number multiplied by the average time it takes you to input one code.

Worked Example

Using the default values from the calculator: a 3‑digit code and 5 seconds per attempt. First, compute the number of combinations: 10³ = 1,000. Then multiply by the time per attempt: 1,000 × 5 = 5,000 seconds. Convert to minutes: 5,000 ÷ 60 ≈ 83.33 minutes. So if you were to brute‑force the safe without any hints, it would take roughly 83 minutes of continuous input.

Where to Find Apartment 5

Apartment 5 is located in the Salvation Harbor area, inside a partially flooded tenement building. You’ll reach it during the main story mission “The Inquisitor’s Ledger” (Chapter 3), after you gain access to the second floor via a collapsed stairwell. The safe is in the bedroom, tucked behind a wardrobe that you must push aside. The code is not random — it’s tied to a note you can find on the kitchen counter, which mentions the owner’s birthday: September 4, 1977. The code 9‑4‑7 is the month, day, and the last digit of the year.

What’s Inside the Safe

• Medical Syringe – restores 50 HP when used.
• 9mm Ammo Box – 12 rounds for your pistol.
• Diary Page – a lore item that explains the owner’s last days and reveals a nearby hidden stash location.

The stash location is a small tool cabinet in the building’s basement, which contains a shotgun shell box and a piece of crafting material. The diary page also provides a clue for a side quest involving a missing neighbor.

How to Input the Code

1. Approach the safe and press the interact button (default: E on PC, X on Xbox, Square on PlayStation).
2. Use the left stick/mouse to rotate the dial. The numbers are on the outer ring; align the pointer with the desired digit.
3. Press the confirm button (default: Space or A) to lock in each digit. You must input all three digits in order.
4. After the third digit, the safe will automatically open. If you input a wrong digit, the dial resets after a short delay.

If you’re playing with a controller, the dial movement is a bit sensitive — move the stick gently to avoid overshooting the number.

Common Mistakes and Tips

• Missing the note: The code is only hinted at if you read the note on the kitchen counter. If you skipped it, you might think the code is random. Always explore the room thoroughly.
• Dial overshoot: On console, the dial can be tricky. Try moving the stick in short taps rather than holding it.
• Safe doesn’t open: Make sure you’ve entered the digits in the correct order. The game expects the code to be entered as 9, then 4, then 7.
• Loot not spawning: If you opened the safe earlier and reloaded a save, the loot might not respawn. The safe is a one-time loot container.

Why the Code Is 9-4-7

The developers at Frogwares often hide codes in environmental storytelling. The birthday note is a classic example: the owner, a man named Harold Finch (no relation to the TV show), was born on September 4, 1977. The code uses the month (9), day (4), and the last digit of the year (7). This is a common pattern in survival horror games — the answer is always in the room if you look carefully. It also reinforces the game’s theme of piecing together the past from fragments.

Frequently Asked Questions

Is the safe code always the same?

Yes, in the current version of the game (v1.0 and all patches as of 2025), the safe in Apartment 5 always uses the code 9-4-7. It is not randomized. If you’re playing a future update that changes the code, the note in the kitchen will give you the new combination.

Can I open the safe without the code?

No, the game does not allow lockpicking or explosive opening for this safe. You must input the correct code. However, you can brute-force it by trying all 1,000 combinations — it will take a long time, but it’s possible if you’re patient.

What happens if I miss the diary page?

The diary page is not missable in the sense that it stays in the safe even if you reload. If you open the safe and don’t pick up the diary, it will remain there until you do. The stash location it reveals is also always available, but you need the diary to know where to look.

Does the safe respawn loot if I revisit?

No, the safe is a one-time container. Once you take everything, it stays empty. If you need more supplies, you’ll have to find other loot caches or craft them.

Is there a similar safe in the same building?

Yes, there is a second safe in the basement of the same building, but it requires a different code that you find in a different apartment (Apartment 3). That safe contains a unique weapon mod and a larger ammo stash.

Final Thoughts

Getting the code is simple if you explore the apartment before touching the safe. The loot inside is modest but helpful early in the game, especially the medical syringe and ammo. The diary page adds a bit of lore and points you to a bonus stash, so don’t leave it behind. If you’re stuck on any other safe in the game, remember the golden rule: the code is always somewhere in the same room or a nearby note.
