🚨 IMPORTANT: Service Availability for W220 S-Class
We DO NOT provide codes for older W220 models (1999-2002) with pre-NTG systems.
The service described here is intended for supported W220 NTG units, commonly found in 2003-2006 configurations, that use the Mercedes Benz Command Code / NTG Anti-Theft PIN system.
What we provide: Original unit-specific NTG Anti-Theft PIN from the OEM code record for supported W220 NTG/COMAND configurations
What we DO NOT provide: Radio codes for older W220 models (1999-2002) with Audio 10/20 systems

✅ NTG Anti-Theft PIN for W220 S-Class (2003-2006)
If your W220 S-Class uses a supported NTG/COMAND system, you may need a Mercedes Benz Command Code (also known as NTG Anti-Theft PIN). Our independent service retrieves the original unit-specific code from the OEM code record using the submitted identifiers; we are not Mercedes-Benz or an authorized dealership. Compatibility and the estimated delivery window depend on the installed unit and submitted identifiers.

❓ W220 S-Class Owner FAQ
Q: My S500 COMAND shows black screen but power LED is on. Will unlock code help?
A: Black screen with power LED usually indicates hardware failure, not anti-theft lock. Try pressing power button and check if screen responds. If completely unresponsive, COMAND repair may be needed rather than unlock code.
Q: After battery replacement, my S320 radio locks frequently. Is this normal?
A: W220 models are sensitive to power interruptions. Frequent locking suggests battery/charging system issues. Check alternator output and consider using memory saver during future maintenance.
Q: My S430 Bose system has no sound after unlocking. What's wrong?
A: Bose amplifier may need separate reset. Try disconnecting battery for 10 minutes, then reconnect. If problem persists, MOST fiber optic network may have issues requiring professional diagnosis.
Q: Can I prevent my S600 radio from locking during service?
A: Use memory saver device during battery work. Inform technicians about radio lock sensitivity. Some Mercedes specialists can disable anti-theft temporarily during major electrical work.
Q: Is it safe to enter engineering mode on my S55 AMG COMAND?
A: Engineering mode should be last resort. Incorrect settings can damage COMAND system. Try standard menu access first. If engineering mode needed, document all original settings before making changes.
Q: My 2000 S-Class has different COMAND than 2005 model. Same procedure?
A: Early W220 (1999-2002) and later configurations use different audio/COMAND hardware. The code service described here is limited to supported 2003-2006 NTG/COMAND configurations; confirm the installed unit before ordering.
