Hi username (lol), and welcome to the forum.
It sounds like you are in the familiar yoyo-stage, where many have gone crazy and some even quit..
A push in the right direction for you would obviously be be a push downwards, assuming you are still trying to release the key. But in order to go down, you may need to rotate, go back, shake, wiggle it (just a little bit)
.
The ramisis moving parts have many possible positions, you just did not find the right one yet to proceed.
Good luck and have fun!
