Door handle button sticking

I had one on our 72 that the button stuck down so I wiggled the button and it popped back out.
Then I got the WD40 and gave it a shot in the center of the button between the button and the handle metal and that solved it.

The OP is going to have to take the panel off anyway to tighten that handle up, or replace it if it's broken because that is in no way normal or something they just do.
Luckily it's a piece of cake to do. :D
