It would seem your VATS system has failed into the operate mode where it allows the computer to operate normally. I suspect you had a few occasions where the VATS may have locked out the key for 3 minutes and then started on the next try? That'* what my 98 did.
You can bypass the resistance reading at the lock cylinder by inserting resistors at the plug near the base of the steering column that are equal to the key'* resistnace in the chip. Or you can do as I am doing, enjoying that the readings failed while the car was running and the unit has gone into bypass mode and everything operates great--just no security reading from the aresistor in the chip.
