Q: Every now and then, when I turn the key, there is no response. Why? on 2010 Chevrolet Cobalt

I have had the ignition relay replaced but the problem continues sporadically.
Have the Ignition Switch (not relay) replaced, and find a dealer or other shop to program the PCM and BCM with the latest calibrations.
