i did have to wedge a small piece of plastic in the hole on the knob to make it shallow enough to allow a knob press to click.

I had to do the exact same thing, only after a really hot day, and i tried to push in my knob button. And I felt the knob sink in, but no click

I cut off part of the plastic lock on a cat5 end, and dropped it in the knob. Worked perfectly
