To progress further in the story of Poppy Playtime Chapter 5, you’ll need to upgrade your mechanical hand with the Pressure Hand. However, the hand is locked inside a locker that requires a code. Here’s how to find the code.
How to Open Pressure Hand’s Locker in Poppy Playtime Chapter 5
After using the Master Key and talking to Giblet, you’ll find yourself in a room with a huge dinosaur in the middle—this is Bron. Bron is important in this area, as he helps you reach higher platforms.

After climbing Bron, you’ll reach an upper platform and a makeshift bridge that can be created by pulling a hanging container. Crossing this gap leads to a room containing the Pressure Hand, which is required to progress.

However, the hand is locked inside a locker that requires a code, and you won’t be able to open it without finding the correct combination.
Pressure Hand’s Locker Code in Poppy Playtime Chapter 5

To find the code, flip the whiteboard in the opposite corner of the same room. Attach your Grabpack to the edge of the board and hold the left mouse button to turn it.

Once flipped, you’ll see several numbers. The code you need is the set of numbers next to the name Luke, which are 0-8-5-9. You need your blacklight to see the hidden numbers.
Return to the locker and enter the code on the keypad by pressing E. After that, the locker will open, allowing you to obtain the Pressure Hand.
You can then use the Pressure Hand to push the hanging container on the other side of the area. This is required to cross the gap, collect an audio tape, and progress further in the story.
