My Keyone makes a sound whenever I lock the screen, either with the left hand key, or with the double tap. Fine. Suddenly today it stopped making that sound. Then it started again. I have no idea why. A few days ago I pulled it out and the screen brightness was turned way down. Took me ages to figure out how to fix that. Any idea why my phone keeps doing these things? I don't care whether or not it makes the sound, I just want to know it is activated/deactivated so I can figure out if I'm doing something wrong.

Well, sounds like you have lock screen sounds enabled - Settings>Sound>Other Sounds> Shut off-screen locking sounds. No idea about your other issue though, that could pretty much be anything, since it only happened once no need to call an exorcist yet lol.
