There’s a lot going on in the unsettling school section of Silent Hill F, and one of the more cryptic puzzles you’ll face involves a series of locked student lockers. What first seems like a simple fetch quest quickly turns into a logic puzzle that connects letters, numbers, and fragments of personal stories hidden in notes around the school.
Some lockers hide key story items that you’ll need to progress, while others reward you with valuable equipment or inventory upgrades. Either way, you’ll want to open all of them. Let’s break down exactly how to crack every combination and what you’ll find inside.
How the School Locker Code System Works
If you dig through journals and scraps of paper scattered throughout the classrooms, you’ll discover that the students used a coded system to “protect” their lockers from teachers. Each letter corresponds to a specific number — it’s essentially a secret numeric language that translates names or words into locker combinations.
The cipher remains consistent throughout this section, and the pattern is the same across difficulty levels (unless noted otherwise). Here’s the base translation used by the students:
| Letter | Number |
|---|---|
| A | 4 |
| B | 8 |
| E | 3 |
| I | 1 |
| O | 0 |
| S | 5 |
| T | 7 |
| U | 6 |
Letters not assigned a number are simply skipped. So if the name is “KEIKO,” you only use the letters that appear in the chart (E, I, O), which gives you the combination 310.
Keep this pattern in mind — it’s the key to every locker in the building.
Aoi Takeshi’s Locker
Aoi Takeshi’s name is short, making this locker the simplest to decode. Using the cipher:
- A = 4
- O = 0
- I = 1
That gives you 401.
Inside, you’ll find an Origami of Grievances, a cryptic paper charm that offers both lore hints and a clue for another locker puzzle down the hall.
Asakura Ayumi’s Locker
Ayumi’s locker is a bit trickier because the combination changes based on your difficulty setting. Her journal entries reveal that she uses a word she “loves” as her code — a subtle hint you’ll find scrawled in the notebook nearby.
- In Story Mode, she loves the “SEA,” which translates to 534.
- On Hard Mode, she prefers “BUS,” which becomes 865.
Inside her locker is the Key Cabinet Key, an essential story item you’ll need to move forward.
Tsuchiya Taiko’s Locker
Taiko’s combination is actually handed to you through a note from another student who wants you to “deal with” her locker. Check your journal — it lists the code explicitly as 377.
Opening it rewards you with the Wolf Omamori, a talisman that slightly increases your attack power when using high-durability melee weapons.
Suga Yosie’s Locker
The final puzzle ties back to the Origami you found earlier. It mentions that Suga Yosie’s combination “sounds like a cry for help,” hinting at the universal distress signal SOS. Translating that using the code:
- S = 5
- O = 0
- S = 5
So, the combination is 505.
Inside, you’ll find the School Bag, which permanently expands your inventory by one slot — a reward absolutely worth the effort.
Final Thoughts
The school lockers in Silent Hill F aren’t just a throwaway puzzle — they’re a clever blend of logic and lore that tie directly into the game’s themes of memory, guilt, and obsession. Each code reveals a little more about the students who once roamed these halls, and solving them all gives you both practical rewards and emotional context.
So next time you pass those lockers, don’t just rush through. Take a moment, piece together the clues, and listen to what the silence of the hallways is trying to tell you.
