Go to GM terminal at dealership and have performed a national history search to the vin# of your vehicle and retrieve radio code that was assigned to that vin ...this should be a no cost search.

I need help to unlock a radio in a 1997 Chevy Cavalier??


InOp means inoperable. There is a 4 digit code that you have to put in on the radio. I don't know if they are all the same code or not, but mine is 0642. read the directions in your car book. If you don't have one let me know and I can scrape mine up. Basically, though any time your battery is diconnected you will have to unlock the radio.
