How does GM PassLock work?
The PassLock system works when the lock cylinder moves a magnet past a Hall effect sensor. The sensor then sends a signal to the control, which GM has moved several times over the model years. The control then sends the code to the PCM. If the code is correct, the PCM will allow the car to start and run.

Is it possible for a car to not start intermittently?
No charge… take the car home and no fix. Again this problem is intermittent. As for driving over ice, yes, this is very possible. The first time I had this problem was when we were driving in roads which were terribly plowed and the car was struggling in several inches of snow. In addition, I live in NH and we had had a ton of snow this winter.
