If you bypassed the VATS at the base of the column that broken wire cannot affect it anymore.
That is probably why you bypassed it in the first place.

We have to go back to post 1 here and give some real information. You have to define how it is the vehicle won't start.
Does it crank but not start? Does it not crank? What works what doesn't?

A lock is a lock, if the key turns then it turns. The electrical part of the switch could be an issue but if the engine cranks and won't start you are wasting your own time.
Passkey 2 (which is what you have) is a starter inhibit system. If you turn the key without a valid code the security light will come on and the car will not crank.
If it won't crank then you need to check your bypass. If you have a mechanical binding condition in that cylinder then you need a new cylinder, if you get a VATS cylinder you will need new keys so it would almost be worth restoring the operation of the VATS in the car if you are going to do that.

The initial issue here is that you have to clarify when you say "the car won't start".
I bet I could find a hundred ways to make a car not start but many of them have unique symptoms. Let's go back and start from the symptoms and find the solution rather than guess what the solution is to discover the problem.
