I have a 2004 Chevrolet Impala. Equipped with "Passlock" factory Theft Deterrent System. Anyway for the past couple weeks SOMETIMES I can try to start my car and it won't do anything. No crack or click or anything. Battery is good, changed the starter and checked fuses....etc. After researching via Google I've learned that year of the Impala is known for major issues with the factory Passlock system. Someone suggested using a passlock bypass module, is that possible? Or can this probably only be fixed by installing a NEW "KEY IGNITION?" PLEASE HELP!!!!!
My car has 180000 miles.
My car has an automatic transmission.
