The Locker Puzzle at Ebisugaoka Middle School is one of the most memorable challenges in Silent Hill f. It combines exploration, note-hunting, and the eerie Girl Code system—a strange cipher invented by the students. While only one locker is required to progress the story, several optional ones contain useful rewards that are worth unlocking.
How the Puzzle Starts
You’ll encounter the Locker Puzzle after completing the Secret Box Puzzle on the second floor. Solving that grants you access to the Old Annex, where exploration leads to the Locker Room Key.
- The Locker Room is on the first floor, near the right stairwell.
- Inside, you’ll find several locked student lockers, each sealed with a three-digit code.
Finding the Locker Room Key
To access the lockers, you’ll need the Locker Room Key, which is located on Asakura Ayumi’s desk in the left classroom of the Old Annex.

From this point forward, you can begin solving the locker combinations either by:
- Collecting the scattered notes to fully piece together Girl Code, or
- Brute-forcing with partial knowledge of the cipher.
How Girl Code Works
The students’ Girl Code replaces letters with numbers or symbols based on their shapes. The notes scattered around the school provide hints, but the core substitutions are:
- A = 4
- B = 8
- D = 7
- I = 1
- O = 0
- S = 5
- T = +
- U = 6
- K = *
- Y = x
For example:
- “AOI” → 401
- “BUS” → 865
This logic is the backbone for cracking every locker code.
