Ok guys, how the hell do I make a round hole with a flat side for the ignition switch? Seems to me if I just make a round hole, the unit will spin with the key when I go to start the engine. Is there a special flat sided drill bit i don't know about?

Or is this another one of those deals where I have to spend 100S of hours with jewelers files making a custom handmade hole?
