How to use the Secret Garden Key in Blue Prince

The Key to the Secret Garden allows you to access the Secret Garden room in Blue Prince. You will need to access the Secret Garden if you want to get one of the Antechamber levers and make your way to Room 46.

This guide will show you how to use the Secret Garden Key in Blue Prince.

How to find the Secret Garden Key in Blue Prince

We found the Secret Garden Key by completing the dart board puzzle in the Billiard Room. The day we found it, we drafted the room at Rank 6 on the eastern side of the house.

How to use the Secret Garden Key in Blue Prince

In order to use the Secret Garden Key, you must find a locked door on the furthest east or furthest west side of the mansion.

Make your way to either side of the house, and continue to draft rooms until you find a locked door. (We went west and continued to draft north as much as our room options allowed us to.) Once you find a locked door, the game will give you the option to use a regular key (if you have one) or use a special key. Click the button that says “Special Keys” and choose the Secret Garden Key. The game will automatically draft and unlock the Secret Garden room.

According to the soil survey results we found in the Apple Orchard shed, the Rank 2 slot on the western side of the house has barren soil. We don’t know if this means that a Green Room (the type of room needed for the Secret Garden Key) won’t spawn there. However, it shouldn’t affect your run that much. You’re better off not drafting Green Rooms early on and instead focusing on drafting rooms that allow you to collect gems, keys, and food so you can make it to rooms with higher ranks.
