Computer is looking for the original key frequency.

I don't remember the VATs system stopping cranking. That you will need to track down.

 

check ignition fuse, heck check em all. lol. does sound like vats is not happy.

 

I believe the VATS also controls the ground to the starter relay coil. Without the this relay, the key switch will not energize the starter. Going to have to find the resistive value of the original key and make a new key with that resistance, do VATS by-pass, or replace the BCM with a new one.
