In this guide, I’m going to walk you through all the possible four-digit codes for the secret door in The Depths in MOUSE P.I. For Hire.
Secret Door Codes
The secret door is exactly what it sounds like a locked door that requires a four-digit code to open. These codes are scattered throughout the game, and each one reveals something different once entered. On top of that, you’ll also get some loot as a reward.
While playing, you’re expected to remember the codes you come across. If you forget them, there’s no easy way to recover them in-game. That’s exactly why I’ve gathered all of them here for you.
Making Your Way to the Door
To access the secret door, I first need to reach the level called The Depths. This area isn’t available right away I have to progress until I unlock the quest Shrewd Shrews. Only after that can I head to this location on the world map.
Once I enter The Depths, I simply progress through the level as usual. Eventually, I’ll come across a massive elevator. I take it down, and when I exit, I arrive at a new section.
From there, I turn left and keep moving in that direction. After a short distance, I spot a building ahead.
I head toward it, walk up the stairs, and enter through the door. Inside, I find the room where I can input the four-digit codes.
This is where the secret door mechanic comes into play.
