Throughout the enchanting yet often unsettling world of Deltarune, players are accustomed to uncovering intricate secret routes and confronting formidable hidden bosses in each chapter. Deltarune Chapter 3 continues this tradition, demanding that players meticulously collect specific items to ultimately unlock the secret boss of Tenna's "TV Time" game show. The journey to this hidden encounter begins with the Ice Key, an elusive item guarded by a mysterious door. This door, in turn, is protected by a sophisticated parental lock system that only yields to those who meet specific criteria during Tenna's broadcast segments.The Ice Key is merely the first of three pivotal items required to access the true secret boss encounter at the culmination of Deltarune Chapter 3. It's notoriously easy to overlook if you're not aware of its precise triggers and location. Even if you fulfill the necessary prerequisites, you could inadvertently walk right past the key's gateway without ever realizing its significance. To avoid the frustrating prospect of replaying the entire opening segment of Chapter 3, it's crucial to remain vigilant and observant in between rounds of Tenna's captivating, yet deceptive, show.

Deltarune: What is the Parental Lock system code

Understanding the Parental Lock System in Deltarune Chapter 3

Upon successfully completing the initial rounds of Tenna's game show, you'll find yourself ushered into the Green Room. This seemingly tranquil space, designed for relaxation and progress saving, features a conspicuous door on its right side. This door, initially blocked by a diligent guard, hints at deeper secrets within. Once you manage to convince the guard to step aside (which occurs automatically as part of the secret path progression), you'll travel down a mysterious hallway, only to be confronted by an elaborate parental lock system. What sinister secrets is Tenna safeguarding behind this digital barrier? What lies beyond this locked threshold? These are the very questions we're here to answer as we decode the parental lock system's intricate passcodes in Deltarune Chapter 3.The solution to each segment of the parental lock system hinges on interacting with the large, illuminated game console located near the lock system's doors. Intriguingly, the character you are currently controlling—whether it's the valiant Susie or the determined Kris—will dictate the specific method you must employ to deduce each numerical answer.

First Parental Lock System Code: Decoding the Misdirection (213)

The first parental lock system's passcode is "213." While the answer is derived from interacting with the game console, the method varies significantly depending on who you are playing as.
  • Solving as Susie (Main Storyline Path): If you've been diligently following Chapter 3's main storyline without yet diverging into its deep secrets, you'll undertake these initial puzzles as Susie. To solve this specific puzzle as Susie, direct your attention to the left monitor of the console. Here, you'll need to carefully pick up one of the interactive blue blocks. Your objective is then to strategically toss this blue block onto the designated button located on the third monitor. Successfully doing so will instantly reveal the third digit of the code: "3." From this point, you'll leverage Susie's unique "weed-pulling" abilities (which allow her to clear certain environmental obstacles) to reveal the digit "2". Finally, you must clear away the remaining blue boxes across the screens to uncover the final digit, "1."
  • Solving as Kris (Secret Path Progression): If you've already ventured behind the "S-rank doors" and played the secret minigame, you'll have the option to control Kris during these puzzles. Playing as Kris generally streamlines the process, as you can efficiently use their trusty sword to effortlessly swipe away at obstructive grass and cumbersome boulders displayed on the console screens. After clearing these obstacles, simply pressing the blue button will reveal the final number, allowing you to quickly spot all three required digits.
The Crucial Trick: Rearranging the Digits Upon solving the visual puzzles, the numbers will initially appear on your screen as what seems like a straightforward "123." However, if you attempt to punch this sequence into the door's passcode boxes, the system will emphatically register it as incorrect. The key to unlocking this puzzle lies in understanding the subtle, yet vital, way each display is interconnected and arranged. Observe closely: the second monitor has distinctive brick walls along its left side, while the first monitor clearly features two visible exits. If you conceptually rearrange these two displays to form a non-linear, sequential relationship, the true password reveals itself as "213." This requires a moment of spatial reasoning, as the numbers aren't read left-to-right in the typical sense.

Second Parental Lock System Code: Trapping the Key (1225)

After a significant exchange betweenRalsei and Kris—a moment that often marks a deeper dive into thechapter's lore—you'll encounter a second parental lock system code to enter. Just like before, you can interact with the giant monitors of the game console to solve its perplexing puzzles, and the method fordoing so remains dependent on the character you are currently playing.

  • Solving as Susie:If you're controlling Susie for this puzzle, you'll quickly notice thateach illuminated path on the screens, while not appearing linear, doesconnect across each display. You will also observe a small, seeminglyelusive key on the screen. As you attempt to approachit, the key will playfully dart away, making it impossible to simplypick up. Your objective is to ingeniously pick up the two blue blocks available and use them as strategic barriers, meticulously crafting a confined space to trap the running key. Once the key is ensnared, Susie can successfully collect it, and thisaction will instantly reveal the second parental lock's passcode: "1225."
  • Solving as Kris:If you're playing as Kris, having already progressed through the secretpathways, this second puzzle is noticeably simpler. You can leverageKris's sword to literally bash open a hidden staircasewithin the display. This act of brute force instantly reveals thepasscode, streamlining your progression through this section. Thismethod, while quicker, underscores the deeper integration of Kris'sunique abilities within the game's secret routes.

Third Parental Lock System Code: The Ultimate Shortcut (000000)

Later on in your playthrough, as you reach a crucial juncture, you'll befaced with the final requirement to input one last passcode into theseenigmatic doors. Despite the intimidating appearance of a six-digitentry field, this third and final code offers a surprising andstraightforward solution. The passcode is simply "000000." Upon entering this sequence, you only need to press "Enter," and thedoor will unlock once more, allowing you to seamlessly progress throughthe remainder of the chapter’s compelling story. This simple final codeprovides a satisfying conclusion to the parental lock puzzle sequence,allowing players to move forward into the concluding segments of Deltarune Chapter 3.
