I installed a Sony radio following the wire diagram and now my car won't start, I've check all fuses and the car seems to be in security lock and have tried the relearn with no success

 

try disconnecting the battery (you call it a lobotomy).
If it doesn't help, then computer diagnostics.
Maybe, when installing the radio, you accidentally made a short circuit and something turned off in the onboard brain or in the alarm control unit. By the way, the alarm is connected to the head unit.

But start with a lobotomy.

 

I also gave that a try, you mentioned that the alarm goes through the radio. I have a base model with no controls on the steering wheel so will I need to install an interface as well. I have had someone hook up a diagnostic to it and clearing the codes didn't work either

 

No start, or no crank?

 

no crank

 

You didn’t install any lan adapter? Just hooked up the Sony?

 

What wiring diagram? Did you get switched power off the fuse box? Is the lock&key symbol lit?

 

I got the wiring diagram off of this site, and I wired it direct and used the switch source for the sunroof at the fuse block ,"which I don't have a sunroof

 

The lock and key symbol is lit

 

You could use any of the "spare" fuse positions in the BCM fuse box' they are switched and delayed (RAP).
Security does not prevent cranking. The lock&key will light up if the battery is dead or disconnected. Maybe you disturbed one of the red wires on the BCM.
I can't think of anything that a normal install could do to the starter. Unless the car has OnStar and you did something to that wiring.
Check Fuses #8, 10, 16, 24 and 25 on the BCM.
