I've concluded it is not. How? I became more observant the next time it happened. I noticed the SECURITY light glowing for 5-10 minutes, the car was not able to start or crank. But after the SECURITY light went off, the car started like there was no issue. Is htis a VATS issue? I have no idea about VATS and I've consulted TECHINFO but there is not anything on VATS. My key pellet is intact and the key is squeaky clean so that'* eliminated (thanks Toasty for the suggestions)
My car occasionally had trouble starting ont he first try. Then I'd wait three minutes for the security light to go off and it would start. Then the light occasionally came on while driving.
I tried turning the key to on and watching for the security light. It should go off after about 10 seconds or less. If it flashes or stays on whether the car starts or not your theft deterret module may be going into failure mode. One failure mode is that it just doesn't do anything because it thinks it has lost its settings. One poster said that if you cause it to lose he resistance reading while the motor is running the module decides it has failed and quit protecting and blocking starts based on resistance reading from the key.
This seemed a lot easier to me than being upside down under the steering wheel or on the right side behind the glovebox putting in resistors at the theft deterent module. Mine has operated for more than a year now this way. Sometimes the security light is on and sometimes it'* not.
I read one poster who said you cut the wires while the motor is running (I assume one at a time to avoid a short) and the module goes into the one mode thinking it has failed.
