Removing Remote 25SL keys

Hi guys

So I opened up my Remote a few weeks ago and took it apart. Very different than when I opened my Radium 49. Much more organized, less cables, etc. etc.

But I was incapable of figuring out how to take out the keys. I could get the springs off and everything, but I could get the keys out of it. Any idea what I'm doing wrong? Is there a latch, or some sort of bizarre technique for twisting off the keys? I want to spray paint them red, though not move them around yet, and I don't want to risk getting any of the crazy wires or sensors screwed up.

Thanks :-)
