8 key logic puzzle

So i saw that there is a new contest on printables called: “Brain teaser puzzles” and I thought it might be interesting to design such a thing, hope you like it! 

You have 8 keys, each with a unique shape. You need to insert them into the correct position out of 16 possible options. Then, you can use a pin to test if you have solved the puzzle. If the pin goes through the hole, you have unlocked the puzzle! You can also use a small plug to make it fall out when you succeed.
