Where's my wallet?

Elimination used for me:

• Red is to the left to the key of the door suggests that the red key is NOT the key to the door.

• The green key is 3 spaces away from the key to the door so the green key is also NOT the key to the door.

• The yellow key is next to the key to the door hence the yellow key is NOT the key to the door.

Now 50-50- either the blue or orange key. Now since the green key is 3 spaces away from the right key, the right key cannot possibly be the orange key as the orange key, being in the middle, is at most 2 spaces away from any of the other keys. This leaves $\boxed{blue}$ as our answer YAY!

Here are the clues listed out:

Red: This key is somewhere to the left of the key to the door. Blue: This key is not at one of the ends. Green: This key is three spaces away from the key to the door (2 between). Yellow: This key is next to the key to the door. Orange: This key is in the middle.

The Red Key, Green Key, and Yellow key all compare their location to the correct key, so they are not the key.

If it was the orange key (in the middle of all of the keys.) Then the green keys clue would be impossible, because you cannot have three keys between green and orange, so it is not the orange key.

Because the blue key is the only key left, we can say that the blue key is the answer.

Here is the order of the keys from left to right.

Green, Red, Orange, Blue, Yellow.

Note for the problem writer: instead of saying this key, (having the keys seek in 3rd person about themselves). Have them seek in 1st person. It took took me a moment to understand that this key meant the key speaking.

If we assume that the orange key is the key to the door, then the green key can not be three spaces away from the key to the door. Likewise, since red, green, and yellow are next to the key to the door, they themselves cannot be it. That leaves only blue to be the key to the door.

We know that only either the Blue key or the Orange key can be the key to the door as all other keys' positions are defined by their relative positions to the true key. The Orange key is never 3 spaces away from the Green key as it is in the middle. This leaves us with the Blue Key as the True key . It even rhymes.

Green , Red and Yellow are not the keys to the door because they have some distance from the key to the door. Orange is in the middle. Orange can't be the key to the door because green wouldn't be 3 space away from it then. So blue is the key to the door.

From clue 1-5 we see Red, Green, Yellow are not the correct key [as they are somewhere relative to the correct key].

If orange is the correct key, then Green must be 3 spaces away according to clue 3. But orange is in the middle according to clue 5. So, we can't place Green key anywhere following clue 3. So Orange key is not the correct key.

That only leaves Blue, which is the correct key.

I guess two points are of note.
1. There are sufficient clues to tell us the identity of the key without bothering to find the order.
2. I don't understand if the keys being able to speak has got any relevance.

Red, Green, Yellow keys give their positions with respect to the required key. So none of them is the required key which leaves with only Orange and Blue. Now, the Green key says that it is three spaces away form the required key, so it cannot be Orange as it is in the middle. Hence our only possibility is Blue and their arrangement is : Red,Blue,Orange,Yellow,Green

Only the Blue key and the Orange key did not mention about any clues in relation to the key to the door. Hence, we can assume that either of the two is the key to the door. From the other clues, the Green key is three spaces from the key to the door which eliminates the Orange key for being in the middle (only 2 spaces available). Therefore, it is the Blue key .

The orange key is in the middle so you have to remember that. Then the green key is 3 spaces away from the key to the door so you count 3 spaces from what would be the start and you put it next to the orange. Then the blue key is not at either of the ends, suggesting it would be next to the orange. Leaving you with a yellow key and a red key. The red key is somewhere left of the key to the door suggesting it is at the end. And the yellow key is next the key to the door, there is only one solution. Blue.

From the start you know that Red, Green and Yellow are not the keys to the door since they reference the door key to their position. Orange is the Middle key, therefore it would be impossible for the green key to be 3 positions from it, therefore it is not the key to the door.

Which leaves us with only one option, Blue

The positions of the keys, from left to right would be, Green, Red, Orange, Blue, Yellow
