What is Mercedes Anti-Theft Protection?

Mercedes Benz COMAND, Audio 20, and Audio 50 head units feature a built-in security system that locks the device when power is interrupted. This commonly happens after battery replacement, electrical repairs, or when the head unit is removed. The system displays "Anti-Theft Protection Active" and requires a unique PIN code to unlock. This code is tied to the device's serial number and can only be retrieved from the official Mercedes database. Our service provides instant access to this database, allowing you to recover your code without visiting a dealer.
