The Mercedes-Benz W221 S-Class (2005–2013) is a high-value unlock request: early cars often run COMAND NTG2.5, while later and higher-option cars use NTG4 / NTG4.5 with richer navigation. Battery replacement in the trunk, air-suspension work, or a dealer head-unit swap commonly triggers the anti-theft screen and blocks phone, audio, and maps. We retrieve the W221 PIN from the official Mercedes database using the COMAND serial and email it in 15–30 minutes; MAP activation is available where the unit supports it. Coverage includes S350–S600 and S63/S65 AMG in short (W221) and long (V221) wheelbase, plus related CL-Class C216 units that share the same COMAND family.

About W221 S-Class Anti-Theft System
The Mercedes-Benz W221 S-Class (2005-2013) 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 W221 S-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 NTG2.5, NTG4, NTG4.5 systems and all S-Class variants produced between 2005-2013, we guarantee compatibility with your specific vehicle configuration.

Tommy Haffman
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.
Carla Megan
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.
Marc Antoine
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!
Sara Smith
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!).
James Wilson
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!
Sophie Klein
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!
