Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
I am sorry for the long wait
since @ 2004 and newer they stopped using a punch in code to unlock these radios they instead used programming in the radios to the cars VIN number so if the VIN number did not match the car it was put into it will be locked
i am sorry to say the only way to unlock this radio is to have a shop or someone with a programming can tool program your new radio to your cars VIN number and then set it up with the scan tool
once that is done it will work fine
