After players survive the red gas prison chamber in Poppy Playtime Chapter 4, they'll journey through the ventilation ducts and arrive in an area with two door shutters. There are two scanners in each room, but activating one will close the shutter door of the other room. Since you'll need to activate both of the scanners simultaneously for the door in the middle to unlock, here's how you can solve this door shutter puzzle.

How to Solve the Door Shutter Puzzle in Poppy Playtime Chapter 4

Players are almost out of the prison area, but first, they must unlock the main door in the area by restoring power to it in Poppy Playtime Chapter 4. The door has two electrical boxes on its sides, with wires going into scanners located in opposite rooms.

You'll need to activate both of the scanners at the same time to unlock the main door. However, the problem arises when you try to use one scanner, the shutter door to the other scanner closes, preventing you from reaching it.

Placing Boxes Under the Door Shutters

However, the solution to this door shutter puzzle is pretty simple. Grab one of the larger boxes near the doorway with the next scanner and drag it under the shutter door. Now go over to the room with the blue scanner, and drag a nearby large box under the shutter. The boxes will act as a doorstop, preventing the doors from closing when you're trying to interact with the scanners.

Activating the Scanners & Unlocking the Door

With the boxes in place, place your hand on one of the scanners and run across the hallway. You'll immediately notice that the other shutter door didn't close all the way and there's ample room for you to crouch under. Activate the second scanner and after a few moments, the large door in the middle will open.

Now, players can step inside the opened door and progress into the next area of Poppy Playtime Chapter 4. However, be warned, as you'll be meeting a vicious creation of the Playtime Co. That'll be a major threat for at least 1/3 of the game.
