hey about those stubborn keys of yours have you tried cleaning beneath them? that happens to me sometimes usually it's like dust accumulating it's normal
if it's laptop keyboard a brush will do (make sure it's side ways and that you give it a few taps on the bottom to make sure the dust leaves) and if it's a separate keyboard you can take out the key and put it back after
Hey, Anon! Unfortunately, it's not that. I keep my keyboard clean and take it apart and dust every few months. That was my first thought, too, and I even changed my key caps (I have two sets).
I'm really not sure what is happening with it. My keyboard is only two years old! I'm going to try and soak my keys in water today and see if dirt isn't inside or something.
It really is driving me insane. But thank you for reaching out and trying to help! I didn't know about the laptop cleaning.
