Silent Hill f Locker Puzzle Solution and All Locker Codes

The Locker Puzzle in Silent Hill f is one of the standout challenges during the Ebisugaoka Middle School section. What looks like a simple locked door quickly turns into a multi-step puzzle where you must decipher a code invented by the students themselves. This “girl code” is the heart of the challenge, and cracking it is essential for progressing through the game.

How to Reach Ayumi’s Locker

You first encounter the puzzle after solving the Secret Box and gaining access to the Old Annex. Inside, you’ll find several notes that introduce the concept of the students’ “girl code”—a cipher where letters are swapped with numbers or symbols that look like them.

Eventually, you’ll discover that Ayumi’s locker is the key to progressing. She left an important item in there, but to unlock it, you must translate her encoded clue from Asakura’s Textbook using girl code.

How Girl Code Works in Silent Hill f

Girl code is essentially a proto-leetspeak system where characters are replaced with numbers or symbols:

  • 1 = I
  • 3 = E
  • 4 = A
  • 5 = S
  • 8 = B
  • 0 = O
  • 6 = U
  • + = T

By applying this cipher, you can turn the words hidden in Ayumi’s notes into a three-digit code that works on the locker padlock.

Ayumi’s Locker Code by Difficulty

The required solution changes depending on puzzle difficulty. Here’s the breakdown:

Story Mode

  • Textbook Clue: “I’m a mermaid… The sea is calling out to me.”
  • Key Word: SEA
  • Code: 534

Hard Mode

  • Textbook Clue: “I’m a tortoise… The bus is calling out to me.”
  • Key Word: BUS
  • Code: 865

Lost in the Fog Mode

  • Textbook Clue: “You can poach it, fry it, and even boil it… mix with flour and sugar to make cake.”
  • Key Word: EGG
  • Code: 399

Opening Ayumi’s locker gives you the Key Cabinet Key, which in turn unlocks the Back Mountains Key in the faculty office—allowing you to continue the story.

Optional Lockers and Their Rewards

While only Ayumi’s locker is mandatory, three other lockers can also be opened for useful rewards. Their codes remain the same across all difficulties:

  • Aoi Takeshi’s Locker – Code: 401
    • Based on his own name in girl code.
    • Reward: An Origami of Grievances (clue for Suga’s locker).
  • Suga Yosie’s Locker – Code: 505
    • Hinted as “a cry for help” (SOS).
    • Reward: A School Bag that expands your inventory by +1. In NG+, this changes to a Shriveled Abura-age offering.
  • Tsuchiya Taiko’s Locker – Code: 377
    • Revealed in an Origami of Grievances.
    • Reward: Omamori [Wolf], increasing your combat effectiveness. In NG+, replaced with a Dried Carcass.

Why You Shouldn’t Skip the Locker Puzzle

The Locker Puzzle does more than block progress—it teaches players how to read the game’s unique cipher. Girl code reappears in other puzzles and notes, so learning it here helps you throughout the rest of the school chapter.

Additionally, grabbing the optional rewards before leaving is highly recommended. The extra inventory slot and the Omamori can make a real difference in the more combat-heavy encounters that follow.
