Deltarune In Chapter 3, players will continue their adventures with Susie and Ralsei in a parallel version of Undertale’s story. After beating the first stage of Tenna’s game show, players will be unable to progress until they figure out what their host is hiding. After talking to Tenna, they can “push the buttons” of the guard blocking the door, but at the end of the hallway, they will be met by another door with a parental lock code.
In this guide, I will explain how to solve both parental lock code puzzles in Deltarune Chapter 3 and provide solutions in case you want to move on to the next part of your adventure.
What are parental lock codes in Deltarune Chapter 3
Forget about puzzles
If you don’t mind solving the puzzles to get both parental lock codes, each one is listed below:
- First parental lock code: 213
- Second parental lock code: 1225
For those who want to know how to actually get the solution and solve the puzzles, keep reading.
How to Solve the First Parental Lock Code Puzzle in Deltarune Chapter 3
Not what it seems at first glance
The first Parental Lock puzzle is pretty simple. After you try and guess and most likely get the code wrong (unless you used the solution above), the TVs in the room will turn on. Interact with the console and you will see three basic rooms. The one on the left has three blue blocks and four brown spots, the second is filled with grass, and the third has an orange switch in the bottom corner.
Start by interacting with all the grass in the middle room. This will reveal a pattern of brown spots. Now head right and you will be on the left TV screen. Grab one of the blue blocks and move it to the orange switch in the right room. This will cause orange spots to appear in the room, which turn out to form the number “3”.
Move the other blue blocks in the left room and you will see the number 1, and in the middle room you can clearly see the number 2. The twist here is the order of the rooms, going from left to right. In other words, the middle room is actually the first room, followed by the left room, and then the right room. This means that the parental lock code is 213 .
Both parental lock code puzzles can be made easier if you earn an S rank in Tenna’s game show. This will give you access to a room with mini-games that will earn you various items. You’ll need to earn more S ranks to unlock more secret mini-games in this room, but one of them will be a sword, making both puzzles much easier. In the first puzzle, you can use the sword to quickly cut the grass instead of pulling it out piece by piece.

So many screens
The second puzzle requires you to get a key to open the door on the bottom right TV. However, as you move around the screens, the key will also move. The trick here is to use the two blue blocks on the bottom left TV to block the path so that the key is trapped. With no way to continue your escape, you will need to catch the key by running into it. This may take a little trial and error, but once you get the blocks in place, it will eventually happen.
You don’t have to place the blue blocks in any specific area. As long as the path is completely blocked, the key won’t be able to escape and you’ll be able to complete the puzzle.
After unlocking the door with the key, the TV screens will now show the code, but it will be mixed up. Just like last time, you need to figure out the order of the screens.
The easiest way to do this is to look for the corners of the bricks shown on the screens. This will reveal the second parental lock code – 2115. .
By entering the code into the door, you can proceed to the next room, which is very cold and has a surprise waiting by the holiday tree. Remember that you can make Deltarune fullscreen if you think the default minimized window on PC is a bit of a letdown.
