In Poppy Playtime Chapter 5, you will encounter several puzzles as you progress further into the game. One of the first puzzles requires you to obtain the Master Key from a locked room. In this guide, you’ll learn how to reach that room and get the key.
How to Reach the First Key

After getting your retractable hands chopped off in Poppy Playtime Chapter 5, you’ll eventually reach a section where you need to obtain the Master Key locked behind an enclosed glass room.
The objective is to loop through a series of hallways to reach the room containing the key. However, Wrongside Outimals roam these areas and will jump you if you get too close. The only way to drive them away is by shining light on them, so this puzzle revolves around restoring power by activating electrical levers.

First, pull the red lever in front of the glass to turn on the hallway lights. Next, head toward the window opening that leads to a small factory area bathed in eerie red lighting.

Use the blue and red ramps to jump down. Straight ahead, you’ll find a hole in the wall with a lever beside it. Pull the lever to open the nearby door.
Inside this room, repeat the process: pull the electrical lever in front of you to turn on the lights, then proceed through the door on your right.

The next room is slightly trickier. To avoid the Outimal on the right side, jump onto the wooden plank and immediately drop down to the left to reach the lever safely.
Once the door opens, move through the train-like structure. Stay close to the right wall to avoid another Outimal, then pull the electrical lever at the end.
In the following area, do the same as before: jump onto the conveyor belt and pull the lever on the left side. Finally, in front of the hanging body, you’ll find a set of double doors. Open them to continue forward.
Crusher Room

After opening the double doors, you’ll find yourself in a room with several crushers. You’ll want to activate the left one. To do this, first pull the electrical lever, then press the button next to it.
This will activate the crusher, causing a star that was stuck inside to fall down. Pick up the star to obtain Glowby, your flashlight in Poppy Playtime Chapter 5.
Once you have Glowby, backtrack your way to the first room to continue progressing.
Getting the Master Key

In the first room, head toward the door at the end of the hallway. Open it and follow the path forward. Make sure to keep your flashlight on to avoid getting jumped by the little critters along the way.

After opening the door at the end of the path, open the door on the left, next to the stairs. Once inside, you can safely pick up the Master Key.
Getting this key marks the beginning of your perilous journey deeper into the Playtime Factory, allowing you to progress further into the story of Poppy Playtime Chapter 5.
