Security locked radio

The radio has been security locked since my purchase. One person told me I could go to a dealer and they would charge roughly $50 to fix, and someone else said that I could call GM and they'd help me over the phone free of charge. Anyone have experience with either one? Both truths?

I would recommend contacting your local dealer for more information. They will be able to assist you further. Please feel free to keep me posted. Thank you in advance.
