Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Hello, my name is***** most likely means the ignition lock cylinder has failed which is responsible for reading resistor built into key. To know for sure first use multi meter to test resistance of key. Then access the two white wires going into ignition switch, both should show same resistance as key whenever you put key in lock cylinder and turning it, if not replace the lock cylinder. This would cost around $250 to have done at a shop. Let me know if you have more questions, thanks.
