Hello, I've opened the keyboard up to this point (check the last few images): https://imgur.com/a/nho47YH I can lift the broken key completely up without meeting any resistance but I'm not sure how to lift the other white keys. I don't want to force it and accidentally break it. I'm trying to lift one of the other white keys and compare what's underneath. Also does anyone happen to see the problem with the pictures I already have? I'm not sure how to open up the keyboard even more than I already have.

The rest of the keys still make noises. I opened part of the piano up and looked in. It looks like the black part might be a bit busted. How do I fix this? If I need to completely dismantle the keys, how do I do that?

I can't press that key all the way down. The rest of the keys still make noises. How do I fix this? The keyboard is a Casio Privia PX-160.
