Signalis: Nowhere Door Codes & Progression Solutions
In the "Nowhere" section of Signalis, direct numerical codes for doors are limited. Progression primarily involves one key safe code and solutions to larger item-based or sequence puzzles that function as "locks."
Incinerator Room Safe
- Code:
0451
- Source: Found on the "Ritual Memento" note, located in the film projector room within Nowhere.
- Use: Opens the safe in the Incinerator Room, containing the Administrator's Key (Office Key) required for progression.
Other Key "Locks" in Nowhere (Non-Numerical)
Beyond the Incinerator safe, major obstacles in Nowhere are bypassed using specific items or sequences rather than keypad codes:

Altar Puzzle Sequence
To access the final area, six Idols must be placed on an altar in the correct order. This sequence is typically:
- 1. The Empress
- 2. The Lovers
- 3. The Magician
- 4. The Hierophant
- 5. The High Priestess
- 6. The Fool
(The Idols are collected from various locations, and their placement order is often hinted at by in-game lore, such as the "Poem for a King" note.)
Three-Lock Door

This door requires the following three keys:
- Serpent Key
- Gold Key
- Blank Key (which may become the Key of Love, Key of Sacrifice, or Key of Eternity based on gameplay factors, but is initially required as the Blank Key for this sequence)
While other areas in Signalis (e.g., Sierpinski-23, Rotfront) feature more traditional numerical door codes, Nowhere emphasizes these unique puzzle solutions for advancement.
