Where to Find All TK Codes in Metroid Prime 4

Okay, so I’m playing through Metroid Prime 4: Beyond’s Ice Belt, and I ran into these Psychic Locks that totally stopped me in my tracks. When I scanned them, they showed me these patterns, but I quickly realized I needed to find TK Codes to unlock them. Basically, there are six of these codes hidden in the game, and I’m going to walk you through exactly where to find all six TK Codes in Metroid Prime 4. Let’s get this done!

Ice Belt Psychic Lock 1 TK Codes – Metroid Prime 4: Beyond

Psychic Lock 1 Location:

Okay, so I found the first Psychic Lock! It’s in the Bio-labs area of Ice Belt. You go down the lab hallway, and after you pass where the path splits off to the left and right, it’s right there at the end. I tried to open it as soon as I saw it, but you definitely need those TK Codes to get it unlocked. Looks like I’ve got some searching to do!

Psychic Lock 1 – TK Code 1:

If you’re facing the Psychic Lock, the first TK Code is located in the small lab to your left.

In the chamber, you’ll find three green pods. Scan the central pod to reveal the first TK Code.

Arrange the code fragments into a diamond shape, matching the example image. This completes the process of obtaining the first TK Code.

Psychic Lock 1 – TK Code 2:

The second TK Code is hidden in a small room just off the main path, before the Psychic Lock. But you’ll need to visit the larger SE chamber first to get the Psychic Lasso upgrade. This upgrade is required before you can get the Psychic Grapple later on. Once you have the Lasso, you can go back and find the Code in the small lab.

In the smaller lab, you’ll notice a few clear cases holding faded, colorless objects. One case contains a single object that remains green. Use the lasso to remove the case’s cover and then scan the green object to proceed.

TK Code. Form it into the proper shape and return to the Psychic Lock.

Once you have both TK Codes, the way forward will appear to the right of the Psychic Lock. Use the Psychic Visor to see the pattern on the lock’s surface, then use the Control Beam to trace it.

Ice Belt Psychic Lock 2 TK Codes – Metroid Prime 4: Beyond

Psychic Lock 2 Location:

The second Psychic Lock in the Ice Belt dungeon is found on the Medical Bays level, specifically in the Staging Corridor. Shortly after entering the Medical Bays from the Bio-labs, you’ll see the Psychic Lock on your left, blocking the way forward until you obtain the key.

Psychic Lock 2 – TK Code 1:

To find the first TK Code, start by searching a small canister in one of the labs off the corridor leading from the Staging Area (where the lock is). Go to the end of the corridor and enter the unlocked lab on the right. Then, use the Morph Ball slot to reach the next lab – the canister with the code is inside.

Psychic Lock 2 – TK Code 2:

You can find the second TK Code by looking at the unusual surgical tools hanging above the bed in the Surgery Bay. This room is located at the very end of the level, and it has long, narrow openings on both sides designed for the Morph Ball.

Psychic Lock 2 – TK Code 3:

Okay, so I finally found the third TK Code for Psychic Lock 2! It’s hidden in the little control room in the Recovery Bay. You have to use the Lasso to get the hatch off the door first. Then, when you check out the screens by the window, you’ll notice one’s frozen over. Melt the ice, and then use the Lasso again to pull that screen down. Once it’s on the floor, scan it and the TK Code will appear!

Psychic Lock 2 – TK Code 4:

The last section of the TK Code within the Ice Belt is the main room of the Storage Bay. This large, cylindrical room is located on the opposite side of the Medical Bays level from the Recovery Bay.

Inside the main chamber, you’ll find a frozen crane arm with a moving joint. Shoot the joint with a missile or a charged beam. This will cause it to release a container holding a frozen creature into the machine nearby. Activate the holographic display to open the container and scan the frozen specimen inside. This will give you the final TK Code and its corresponding shape. After you’ve done that, go back to Psychic Lock 2 and finish entering the code.
