Afternoon, all. I replaced the ignition switch (GM#15795321) in my 2009 H3T Alpha that creates the pesky intermittent no-start fault. The Internets had a multitude of opinions on how to bypass or what the procedure itself is. I found one that worked on the T. I typed it up step by step, so nobody has to watch 18 youtube videos anymore. I also posted this in the "Tech Library". See below.
