The Sinking City 2 safe code

All safe codes and lock combinations

These answers were cross-checked against the linked puzzle collection and several completed walkthroughs. They are investigation solutions used by locks and machines inside the game, not promotional redemption codes.

Apartment 5 safe code — 1908

The first optional safe is in the upper-floor apartment at 12 Garrison Street during A New Day. A note attached to the safe describes the combination as the owner's proudest and most miraculous moment, but it does not print the four digits directly.

The related Radio Store evidence says that the business opened 21 years before the game's 1929 setting. Subtracting 21 from 1929 gives 1908, which is also presented by the environmental Allen Radio Store clue. Enter 1-9-0-8 to open the safe and collect the supplies inside.

This is the same safe covered in the supplied beginner walkthrough. Knowing the answer early does not break the main route because opening it is optional.

Church floodgate code — 1672

The Redemption Church floodgate is a progression lock rather than an optional loot safe. The attendant's note tells you that the required number is the year the church bell was made, while two other church documents supply the missing dates.

The church was founded in 1667, and the bell was installed half a decade later. Adding five years produces 1672. Enter that number on the floodgate padlock to continue the water route.

Players who want to solve it through the investigation system should read the church's origin document, the report about the bell, and the note near the gate before entering the answer. The number itself remains fixed.

Devil’s Reef Room 301 safe code — 2137

The Room 301 safe appears on the third floor of the Devil’s Reef hotel area, also described by some guides as the Siren’s Call safe. You can reach the safe before collecting both pieces of evidence, which is why many players assume they missed a clue.

The intended answer comes from a note pointing to the lyrics of Baby, One More Tide. Counting the body parts described in the relevant lines gives 2-1-3-7. Push the shelf aside where required, then enter 2137 on the safe.

The supporting notes are found around the hotel, including a small room near the first-floor bar and Room 303 after obtaining the Staff Key. You may enter the answer immediately or collect the evidence first for the full investigation context.

Akeley Hospital storage code — 1308

The locked storage area is in the basement of Akeley Memorial Hospital. Accessing the lock also involves obtaining the item needed to deal with the corroded door, so the code alone may not let you enter the room from the moment you first see it.

Four hospital documents each contribute a digit and its position. The clue trail passes through the Outpatient Room, Workshop Materials Room, the terrace beyond the General Ward, and the Nurse Station. Put those digits together as 1308.

Return to the basement storage entrance, use the required Anti-Rust Acid where prompted, and enter 1-3-0-8. The room is optional but contains supplies and a weapon attachment, making it worth opening before leaving the hospital.

Hospital brain machine code — 13-05-36

The Wireless Room brain puzzle is a three-part number sequence rather than a four-digit safe. Its full investigation route begins after obtaining the Old Man’s Mask, continues through the Therapeutic Garden announcement, and uses Father Nathaniel’s mask to reach Medical Records and the Wireless Room.

Interact with all three brains and set the machine to 13, 05, and 36 in that order. Keep the leading zero on the middle value. Confirm the sequence only after all three displays match.

This solution is listed here because players search for it as a password, but the separate puzzle guide explains the surrounding hospital devices and rotation puzzles.

Fish Market buoy symbol lock

The GamerSky link supplied for this update is page 10 of its full puzzle-and-password collection and specifically identifies the Fish Market buoy-pattern lock. It belongs on the safe-code page because it is a lock combination, although the answer uses pictures rather than digits.

The evidence pair About Ezekiel and From Ezekiel’s Wife points to four recognizable symbols. Select them in this order: Lighthouse → Ropes → Starfish → Octopus. The lock is attached to the optional Fish Market side-room route and rewards an upgrade when opened.

The third-party screenshots are not reproduced here. The sequence has been rewritten in accessible English so US players can follow it without reading the Chinese image labels.

Salt Storage Roman-numeral code

The Cutting Area contains the Salt Storage door with a grid of Roman numerals. Documents about Sybil and the Sixteen Punishments investigation indicate which four positions are required.

Press I, IV, IX, and XVI, then hold or use the confirm action shown by the interface. Some walkthrough captions have circulated with an XI/IX inconsistency, but the written solutions cross-checked for this page agree on IX.

Inside Salt Storage you can obtain an upgrade reward and the evidence needed to understand the related Locker Room safe. Search the room before returning to the market route.

Fish Market Locker Room safe code — 1496

The Locker Room safe follows the same numeric idea as the Roman-numeral door. A four-digit safe cannot accept sixteen as a two-digit final entry, and the local note clarifies that the last value becomes six.

Convert the pattern to 1-4-9-6 and enter 1496. This is also the numeric counterpart to the buoy and Salt Storage investigations in the Fish Market chapter.

Fish Market memory safe code — 6294

Later in the Fish Market sequence, a memory scene leads through the Old Shop and Abandoned Office. Listening to the phantom conversation reveals the combination, but the safe can be opened directly with 6294 once the memory route makes it accessible.

Enter 6-2-9-4 and take the story item inside. This safe is part of progression through the memory sequence, so opening it serves a different purpose from the optional supply safes earlier in the game.
