This software utility is designed to retrieve or compute security codes for compatible Volkswagen factory radios and infotainment systems. Unlike generic "master codes"—which don't exist because codes are personalized to a vehicle's VIN—this tool uses the radio's unique serial number to generate the specific unlock digit.

To use any calculator, you need your radio’s unique "digital fingerprint."
