The first-generation Mercedes GLC (X253, 2015–2022) uses COMAND Online NTG5 / NTG5.1 / NTG5.5. It is a high-volume SUV for battery and multimédia work — and therefore a frequent anti-theft lockout case. Enter the COMAND serial on our form and we return the PIN from the official Mercedes database within 15–30 minutes. SUV and Coupe, diesel/petrol/AMG (GLC43/63) are covered. Looking for the newer X254 GLC with MBUX? Use the X254 model page instead.
The Mercedes-Benz X253 GLC-Class (2015-2022) 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.
Our service provides the exact anti-theft PIN code, command code, HU PIN code, or MAP activation code that your X253 GLC-Class requires. We use the official Mercedes-Benz database to calculate your unique code based on your serial number or VIN. The process is completely safe, dealer-approved, and does not void your warranty. With support for NTG5, NTG5.1, NTG5.5 systems and all GLC-Class variants produced between 2015-2022, we guarantee compatibility with your specific vehicle configuration.

Great & fast service. Got my Mercedes W212 anti-theft code quickly after battery replacement, and it worked perfectly! COMAND system is back to normal. Highly recommended.

My Mercedes C-Class showed Anti-Theft Protection Active for 2 months after head unit swap. Got the code super fast from AntiTheftCode — wish I knew about them earlier! Saved me a trip to the dealer.

Excellent anti-theft code service! My Mercedes E-Class COMAND was locked after disconnecting the battery. Received my code in 10 minutes and system is back up and running. 5-star experience!

Fully recommended 5/5. Very nice support team, they helped me get the anti-theft code for my Mercedes GLC in less than half an hour. Much cheaper than the dealer wanted (€120!).

Very impressed! After struggling with my Mercedes S-Class anti-theft protection for weeks, got the code in less than an hour. Professional service and only €25 — dealer quoted me €150!

Brilliant! My Mercedes W204 COMAND was locked after a battery change. They sent me the anti-theft code almost immediately. €25 instead of €100+ elsewhere. Will recommend to everyone!
