We purchased this vehicle used and have been pleased except for one thing. At times the security light would blink when we tried to start it, and if the light was blinking it would NOT start. We took it to a Chevrolet dealership for service and they said the security system was not original but after market. We had the system removed. The car started fine for a long time, then all of a sudden it has started doing the same thing again, intermittently. All you can do is wait until the security light stops blinking, 5-10 minutes, then it starts fine. Could this be due to a sensor? It even refuses to start sometimes first thing in the morning.
