Center console screen/radio does not come on, interior lights, high beams, and electronic door locks do not work.

The first thing I would do is check the ECU-B1 fuse which is in the fuse panel under the hood. This fuse runs all of the systems you have motioned, this video will help.

Check out the images (below). Please let us know what happens.

Awesome, thanks man! I’m going to pull it into the garage this afternoon, and I’ll check it out. Really appreciate the input, I’ll update here on what I find.

The ECU-B1 is a 10A fuse and it’s good. I replaced it just in case. No luck

Not sure, I don’t know what that means. It has a fob and I have to touch it to the ignition button to start it. How would I find out?
