The Red Compartment is a locked storage puzzle you solve by finding and placing three colored keys

The red compartment in Riddle Transfer 2 is a locked box that sits in the main game area. To open it, you need to find three keys — one red, one blue, and one yellow — and place them in the correct slots on the compartment's face. Each key unlocks a different colored lock, and all three must be inserted before the compartment opens and gives you the item inside.

The puzzle itself is straightforward once you have the keys in hand. The real work is finding where each key is hidden in the game world. The keys are not lying out in plain sight; you have to explore the environment, solve other smaller puzzles, and talk to characters to learn where they are.

Key Takeaways

  • The red compartment requires three colored keys — red, blue, and yellow — placed into matching colored slots to open.
  • The red key is found by solving the puzzle in the upper left area of the game, which involves moving objects in a specific order.
  • The blue key is hidden behind a locked door that opens after you complete the middle section's logic puzzle.
  • The yellow key is obtained by talking to a specific character and completing their requested task.
  • Once all three keys are in your inventory, return to the red compartment and insert them into the matching slots in any order.

Where to find the red key

The red key is located in the upper left section of the game map. In that area, you will find a small puzzle involving three movable blocks or crates. The solution requires you to push or arrange these blocks in a specific sequence — usually in a pattern that creates a path or opens a hidden space.

Pay attention to any visual clues in that area, such as markings on the ground or arrows painted on the walls. These often indicate the order in which you should move the blocks. Once you have arranged them correctly, a compartment or drawer will open, and the red key will be inside.

Where to find the blue key

The blue key is behind a locked door in the middle section of the game. To unlock that door, you must first solve the logic puzzle in the central area. This puzzle typically involves matching symbols, numbers, or colors in a grid or sequence.

Once the logic puzzle is solved, the door will unlock automatically. Enter the room beyond and look for the blue key on a shelf, table, or in a small alcove. If you do not see it immediately, check the corners and edges of the room carefully.

Where to find the yellow key

The yellow key is obtained through interaction with a character rather than by solving a puzzle. There is a specific NPC in the game who will give you the yellow key in exchange for completing a task or bringing them an item they request.

Talk to all the characters you encounter as you explore. One of them will mention needing something — often an object you can find elsewhere in the game world. Retrieve that object, return it to the character, and they will hand over the yellow key as thanks.

How to insert the keys into the red compartment

Once you have all three keys in your inventory, go back to the red compartment. Look at its face — you will see three colored slots or keyholes, one for each color. The slots are usually labeled or color-coded so you know which key goes where.

Open your inventory and select the red key first. Move your cursor over the red slot on the compartment and insert it. Repeat this process with the blue key and the blue slot, then the yellow key and the yellow slot. The order in which you insert them does not matter; the compartment will only open once all three are in place.

After the third key is inserted, the compartment will unlock with a sound or animation. The door or lid will open, revealing the item inside. Take the item — this is usually an important object needed to progress further in the game.

What to do if you cannot find one of the keys

If you have searched thoroughly and cannot locate a key, backtrack through areas you have already visited. Sometimes a key only appears after you have completed a certain puzzle or spoken to a certain character. Return to the upper left, middle, and character areas and check again.

If you are still stuck, try solving any remaining unsolved puzzles in the game. Many games in the Riddle Transfer series gate items behind puzzle completion, so finishing other challenges may unlock access to the key you are looking for. You can also try talking to characters again — they sometimes provide hints if you speak to them a second time.

Frequently Asked Questions

Do I have to insert the keys in a specific order?

No. The red compartment will accept the keys in any order. You can insert the red key first, last, or in the middle — it does not matter. All three must be inserted before the compartment opens, but the sequence is up to you.

What happens if I lose one of the keys?

Keys in Riddle Transfer 2 cannot be lost or dropped. Once you pick up a key, it stays in your inventory until you use it. If you think you have lost a key, check your inventory screen to confirm it is there. If it is not, you have not found it yet.

Can I open the red compartment without all three keys?

No. The compartment requires all three keys to unlock. If you try to insert only one or two keys, nothing will happen. You must find and insert all three colored keys before the compartment will open.

Is there anything else inside the red compartment besides one item?

The compartment typically contains one main item that is important to the game's story or progression. Some versions may include a small bonus item or note, but the primary reward is a single object you need to keep and carry with you.
