I was trying to figure out last night if the radio was not factory or the anti theft was not factory.

It's all a best guess anyway, that's all we can do!

I would use my Tech2 to test the system but it's not fun to have that BS happening.

There was a manufacture recall on the ignition switch for 2003 Malibus. This affects the anti-theft on the cars. We are in the process of the same thing. I HATE that anti-theft!!!
