While navigating through the icy depths of Metroid Prime 4: Beyond in the Ice Belt dungeon, players will encounter two formidable Psychic Locks that can momentarily impede progress. To unlock these barriers, you must gather a total of six TK Codes, which are essential for deciphering the unique patterns hidden within the locks. This comprehensive guide will detail the locations of all six TK Codes found within the game.
Psychic Lock 1 TK Codes – Metroid Prime 4: Beyond

Location of Psychic Lock 1:

The first Psychic Lock can be found in the Bio-labs area of the Ice Belt. It’s situated at the end of the lab corridor, just after the paths diverge to the left and right. Although you can engage with the lock upon discovery, unlocking it requires the TK Codes.
Psychic Lock 1 – TK Code 1:

To locate the first TK Code, head to the small lab on the left side of the main pathway leading to the Psychic Lock.

Inside this chamber, you’ll discover three green pods. Scan the central pod, which will unveil the first TK Code.

Select and position the cipher pieces to form a diamond shape as illustrated. Completing this step will grant you the first TK Code.
Psychic Lock 1 – TK Code 2:

The second TK Code is located in a smaller room to the right of the primary passage to the Psychic Lock. Before retrieving it, however, you must access the larger SE chamber and acquire the Psychic Lasso upgrade, which precedes the Psychic Grapple obtainable later in the game. With this upgrade, you can proceed to the smaller lab.
Once inside, look for transparent display cases filled with dull objects. In one, discover a vibrant green item. Use the Psychic Lasso to unveil it, then scan it to reveal the second TK Code. Position the pieces correctly and return to the Psychic Lock.

With both TK Codes secured, a solution pattern will appear next to the Psychic Lock. Use your Psychic Visor and Control Beam to accurately trace the pattern on the lock’s surface.
Psychic Lock 2 TK Codes – Metroid Prime 4: Beyond

Location of Psychic Lock 2:

The second Psychic Lock can be found on the Medical Bays level, specifically in the Staging Corridor. Upon reaching this level from the Bio-labs, the Psychic Lock will be immediately visible to your left, blocking progress until you obtain the required codes.
Psychic Lock 2 – TK Code 1:


The first TK Code can be obtained by scanning a small canister positioned on a shelf within one of the labs located down the corridor adjacent to the Staging Area where the lock is found. At the corridor’s end, turn into the lab on the right and enter the Morph Ball slot leading to the next chamber to discover the object.
Psychic Lock 2 – TK Code 2:


The second TK Code is hidden within the unusual surgical devices above the medical bed in the Surgery Bay. This chamber is positioned at the far end of the level and connects with two long Morph Ball slots on either side.
Psychic Lock 2 – TK Code 3:

The third TK Code can be found in the small control chamber located in the Recovery Bay. Employ the Lasso to remove the hatch blocking the door. Inspect the nearby screens — one will be covered in ice. Clear the ice away, and then use the Lasso to lower the screen. Once it’s on the ground, scan the screen to uncover the TK Code.
Psychic Lock 2 – TK Code 4:

The final TK Code in the Ice Belt can be found in the central chamber of the Storage Bay, a large cylindrical area at the opposite end of the Medical Bays from the Recovery Bay. In this chamber, observe a crane arm with a frozen power joint. Utilize a missile or charge beam to thaw it out. This action drops a griever pod into an adjacent apparatus. Engage with the confirmation hologram to access the pod, and then scan the frozen griever specimen contained within to reveal the last TK Code and its shape. After organizing the final code, return to Psychic Lock 2 to inscribe the completed code.
