After entering the room, you will spot three screens and a blocked exit protected by a parental lock system code. Enter any code to activate the monitors. Then, approach the screens to access the minigame. The left screen displays three blue blocks and four brown patches, the middle screen shows grass, and the right screen contains an orange switch.

Start by removing the grass on the middle screen to reveal the number 2. Next, go through the opening to the left screen and move one block to the third screen. This exposes the number 3. Afterward, remove the remaining boxes on the first monitor to reveal the number 1. Although the numbers appear in the order 1-2-3, the correct code is 213.

After entering the first parental code, you will gain access to the next room, which contains six screens. By analyzing them, you will notice that there are openings allowing you to move across the monitors. There is also a locked gate on the sixth screen and a key on one of the remaining screens, which moves as you move.

To collect the key, begin by picking up the two boxes and blocking an exit to limit the key’s path. Next, analyze the movement pattern of the key and position yourself accordingly to trap and collect it. Once you have the key, proceed to the final screen and open the gate.

Afterward, you will see some jumbled numbers, from which you need to form the correct code. The easiest way is to pay attention to the brick boundary. It reveals that the number starts with 1 and ends with 5. So, the correct second parental lock system code is 1225.

That was all about the parental lock system code in Chapter 3 of Deltarune.
