How to Enter the Antechamber – Blue Prince

So you’ve found the Antechamber—and all three doors are locked tighter than your vault at home. Don’t panic. There are actually three separate ways to bust into the room. You’ll only need one, but getting in can take some planning… or just dumb luck.
Here’s how each method works.
Method 1: The Greenhouse Lever
This one’s simple—on paper. First, you need to find the Greenhouse room. It’s a green room (so you’ll need Spread) and it shows up randomly. Inside, you’ll see a busted switch panel. To fix it, you need to bring a Broken Lever.
Where do you find that? Good question. It can spawn in a lot of places, but the Security Room and Spare Room seem to be common ones. If you find the lever before the Greenhouse shows up, toss it in the Coat Room to store it for your next run.
Install the lever in the Greenhouse, flip the switch, and the south door of the Antechamber will open.
Method 2: The Great Hall Lever
For this one, you need to find the Great Hall, which usually hides behind a Silver Key door. You can get Silver Keys in places like the Billiard Room or the Locksmith. Once inside the Hall, you’ll see a bunch of locked doors.
Behind one of them is your lever.
You’ll need to open up to six doors to find it, so stock up on keys. You can also find a Lockpicking Set to make things easier. Or just draft the Foyer, which unlocks all hallway doors and makes this process way less painful.
Once you pull the lever, the north door to the Antechamber unlocks.
Method 3: The Secret Garden Lever
To go the garden route, you need the Secret Garden Key. This shows up randomly, but the Billiard Room, Music Room, and Locksmith are your best bets. Once you’ve got the key, use it on one of the mansion’s outermost locked doors.
Inside the Secret Garden, there’s a statue in a fountain surrounded by weather vanes. Turn the nearby valves until all three vanes aim at the statue. A hidden lever will pop up. Pull it, and the west door to the Antechamber opens.
What’s Inside?
Once you’re in the Antechamber, check out the note and grab the Basement Key. That’s your next stop. Don’t miss it. It’s kind of a big deal.
You'll only need one lever to get in—but if you're feeling spicy, go for all three. The room doesn’t care. It just wants your patience.
