The Parental Lock Code in Deltarune Chapter 3 is one of the more cryptic puzzles players encounter during their journey through the TV World. This locked system blocks access to a secret area after the first segment of Tenna’s game show. To unlock the door, players must solve two separate puzzles and input specific codes that differ depending on whether they’re controlling Kris or Susie.
In this guide, we’ll cover how to find and solve both Parental Lock puzzles, explain the roles of characters in each segment, and provide the codes needed to progress further into the chapter’s hidden areas.
What Is the Parental Lock in Deltarune?
The Parental Lock system is a two-phase security door puzzle that appears shortly after players complete the first part of Tenna’s televised game show challenge. Located near the Green Room, the locked door prevents further progress unless players input the correct codes.
Each code is revealed through a character-specific puzzle, and different mechanics apply depending on whether you’re playing as Kris or Susie. Solving both parts of the lock reveals new rooms and potential clues related to the chapter’s secret ending.
How to Solve the First Parental Lock Code (213)
After the first game show segment, players enter a monitor room where they must interact with the environment to reveal the code.
Code: 213
Kris Path:
Use Kris’s ability to slash through barriers in the room.
This reveals hidden screens and buttons, ultimately showing the code 213.
Susie Path:
Susie uses her strength to pull grass or disrupt environmental elements.
Revealing screens requires more physical interaction.
Once triggered, three numbers appear in the correct order: 2 – 1 – 3.
Once you identify the code, return to the Parental Lock panel and enter 213 to unlock the first gate.
How to Solve the Second Parental Lock Code (1225)
The second lock puzzle occurs after a segment involving Ralsei, and again diverges depending on the active character.
Code: 1225
Kris Path:
Kris can destroy the ladder near the area using their slash ability.
Doing so reveals a hidden key and the corresponding code 1225.
Susie Path:
As Susie, players must reposition blue blocks in the environment.
Arrange the blocks to trap the moving key, triggering the screen to display 1225.
This puzzle is more intricate than the first and often requires some trial and error. Once solved, return to the second panel and input the code.
Summary of Codes
| Lock Stage | Code | Method (Kris) | Method (Susie) |
|---|---|---|---|
| First Lock | 213 | Slash barriers to reveal | Pull grass to activate display |
| Second Lock | 1225 | Destroy ladder to unlock key | Block puzzle to trap key |
Both codes must be input in order to fully unlock the Parental Lock door and continue exploring the secret areas of Chapter 3.
Why Is This Puzzle Important?
While not mandatory for completing the main storyline, solving the Parental Lock puzzle:
Grants access to optional areas containing lore or bonus content.
Provides further connection to TV World secrets and Tenna’s manipulation.
May affect how players approach the S-rank path and secret boss route.
Players seeking full completion or deeper narrative insight should prioritize solving this lock.
