If you have the Factory Radio in your 2003 2500, there is no Customer Radio Unlock Code.
The factory Radio is a Class 2 DATA Type Radio. You will need the Dealer to connect Tech 2 Scan tool to vehicle. They will download info from vehicle. Upload that info to GM Computer. Download GM info & Unlock Code from GM. Upload GM info & Unlock Code back to your vehicle
