Like many people I have bought a true lemon with this 2002 Chevy Impala. We have had nothing but problems since the day we got it. The security light keeps going on and then the car refuses to start. We have spent countless hours and lots of money trying to get a resolution. The last mechanic we spoke to said that he had heard there was a way to bypass the passlock feature by disconnecting it somehow from the radio. I WANT TO DO THIS! I have had it with this car! However, I need some clear instruction on how to do this so I don't mess up more systems. Has anyone done this successfully and if so, can you tell me how?
