About W203 C-Class Anti-Theft System
The Mercedes-Benz W203 C-Class (2000-2007) is equipped with an advanced anti-theft protection system integrated into the COMAND head unit. When the battery is disconnected, the head unit is replaced, or the vehicle undergoes certain electrical work, this security feature activates and displays the message "Anti-Theft Protection Active." This is a factory-designed security measure that prevents unauthorized use of the head unit — however, it can be frustrating for legitimate owners who simply need to restore their system after routine maintenance.
For supported requests, our service matches the original, unit-specific anti-theft PIN, command code, HU PIN or MAP activation code from the official/OEM code record using the submitted serial number or VIN. AntiTheftCode.com provides this independently and is not Mercedes-Benz or an authorized dealer. Compatibility with NTG1, NTG2 depends on the submitted unit and vehicle details.
