Sometimes the BCM can have issues, but a lot of the time it is in the ignition cylinder like suggested, there is a bypass made that will allow the vehicle to start no matter what part of VATS is bad.
Usually the security light will stay on when it is a VATS issue, the fact that it comes on, then goes off in a few seconds makes me think it may not be a VATS related issue.

When all is well, the security light is supposed to come on for a few seconds, then go out. If it continuously blinks, it means it reads no resistance (broken wire usually) or if it stays steady, it reads the wrong resistance.
