    Usually you push the metal can downward and twist…it should pop off.

    yea. push down, then turn counter clockwise about a 1/2 inch, then release, and it'll pop up. there's a spring under there. you can see the grooves at the base for the nub. Once you do it, you'll feel like an idiot how easy it is.

    Push, twist. Just like a bayonet light bulb.
