The Cylinder key puzzle is the main puzzle at the start of Act II-II in Scorn. It is an easy puzzle but can be annoying due to the backtracking and moving toward certain dead-end areas. Nonetheless, this guide is here to help you find the exact procedure for solving the puzzle without any trouble.
The Cylinder key puzzle is part of Act II-II. Solving it will give us access to the locked door decoder, which helps us progress further up the levels. But yes, before that, you’d need to solve the cylinder puzzle, which requires us to interact with various chambers and unlock tunnels to get past the levels, which can be a little tricky.
The gore details of the game can be frightening and scary to look at but also quite fun so if you wanna know more about it, check out our in-depth review of the game: Scorn review.

Finding The Cylinder Key

The First Cylindrical Key Console

After opening it, you can see the rings, which is a simple puzzle where you’d have to lock the outer moving ring of the circle with the other multiple rings. When you move the key, you see the six notches where the rings lock-in.
The task at hand is to move the outer ring, such as it fixes with the inner rings. You do that by moving the key clockwise, which in turn moves the outer ring to the southwest or fifth notch point, the middle ring to the southeast or third notch point, and the inner ring to the northeast or second notch point. Assemble all the rings to the north or first notch point to retract the Cylindrical key.
Finding The Three Tunnels

So, after backtracking down the corridor into the room with glowy red pods. To the right of the oval-shaped case, which you cannot use right now, you interact with a cylinder slot that opens up the gate through which you can pass.
Next, you interact with a Freddie Krueger-inspired switch that brings down the dingy elevator. Stand on it and ride it up. Look for the narrow passage and try not to waste time on dead ends. In the narrow bone-like tunnel, you will find a shift controller.
Three Tunnels

The right tunnel is obstructed by some creepy-looking corpses, so you cannot pass through that tunnel yet. So we will choose the left tunnel first and move forward when the passageway extends and attaches to the tunnel to form the bridge.
Left Tunnel

Middle tunnel

Right when you’re about to leave, a minor jump scare will occur, and the creature will attack you. It is frightening to observe but rest assured, nothing will happen, and you’d be left with a Jackhammer gun, so yeah, not bad for a near-death experience, Right? The combat doesn’t start until later in the game.
Go toward the fans you just disabled. The path will guide you to the third cylindrical key console, which will be solved entirely like the previous console but with a different combination.
Insert the key into the console like before, but now the combination is the outer ring locked into the southwest or fifth notch point, the middle ring locked into the north or first notch point, and the inner ring will be locked into the southeast or third notch point. Assemble the rings and bring them to the center. Retract the key and see it being upgraded throughout the console puzzles with a ring.
Spike Key Implant

Backtracking Towards The Left Tunnel

There will be a corpse on top of the control mechanism, so that we will remove it. Utilize the spike key implant to control the spine-like arm of the glowing brain in the middle of the corridor.

The Last Cylindrical Key Console

The combination for the console is the outer ring locked into the northeast or second notch point, the middle ring locked into the southeast or third notch point, and the inner ring locked into the southwest or fifth notch point. Due to half of the circle being covered, you would have to listen to the clicking sound to determine whether it is parallel to the key. Move the rings to the center and north up to complete it. Retract the key and see i tbeing fully upgraded with all 4 rings.
The Final Puzzle


All the white nodes move at the same time, making it harder to fit each node into each opening. You need to move the nodes one by one until every node is connected to every opening. If a white node gets stuck and can’t move up or down, the other nodes will be able to move.
Though you can try to solve the puzzle through repeated attempts until you finally succeed, we’ll give you a thorough solution.
Shift the first white node to the lower red opening and lock in by moving left once. Move the second white node to the upper red opening, up four times, and left once. Shift the third white node to the lower red opening, move down four times, and left once. Move the fourth white node to the middle red opening, move up twice, and left once. Move up twice to solve the puzzle.
Locked Door Decoder

The second object is a spider-like creature that will have healing orbs attached to it later in the game. After obtaining both of these objects, the puzzle is completed. You are now free to advance to the next level.
