Mercedes W204 Radio Code - Complete Guide [2026]

Independent code-information service • Support available 7 days a week
Is your Mercedes W204 head unit showing a code or anti-theft message? W204 vehicles were fitted with different Audio and COMAND generations, so the search phrase Mercedes radio code can refer to two different credentials. Identify the installed unit and read the exact on-screen prompt first.
⚠️ Important: Radio Code vs. NTG PIN
A legacy radio that explicitly requests four digits may use a classic 4-digit radio security code. A supported COMAND/NTG unit may instead require a unit-specific 25-character anti-theft PIN, whose application method depends on the NTG generation. They are not interchangeable, and the W204 model year alone does not determine which one is required. For supported units, our independent service provides the original unit-specific Mercedes Benz Command Code from the OEM code record using the submitted identifiers; we are not Mercedes-Benz or an authorized Mercedes-Benz dealership.
Before ordering: record the head-unit model, serial number, system generation and exact screen message; do not convert or shorten one credential format into the other.
The Mercedes-Benz W204 C-Class (2007-2014) was offered with different Audio and COMAND systems, including NTG generations such as NTG2.5 and NTG4. The required credential and entry workflow depend on the exact installed unit, not simply the chassis code.

🔒 Why Does W204 Radio Lock?
Your Mercedes W204 radio locks as an anti-theft security measure. This happens when:
- Battery Disconnection - Most common cause during battery replacement or repair work
- Power Loss - Electrical issues, fuse problems, or alternator failure
- Radio Removal - Taking radio out for repair or replacement
- Wrong Code Entry - Entering incorrect code 3 times locks the system

How to know if your W204 radio is locked:
- "CODE" Display - Screen shows "CODE" or "Enter Code"
- No Sound - Radio powers on but no audio output
- Dead Display - Screen is blank or shows error message
- Locked After Attempts - "WAIT 1 HOUR" or similar message

🔢 How to Enter Code in W204
Method 1: Legacy 4-Digit Radio Code
- Use this workflow only if the identified legacy unit explicitly requests a 4-digit code
- Follow the controls and confirmation sequence documented for that exact radio
- Do not enter part of a 25-character COMAND/NTG PIN as a 4-digit radio code
Method 2: COMAND/NTG Anti-Theft PIN
- Confirm the COMAND/NTG generation and the exact anti-theft message
- Use the complete 25-character, unit-specific PIN supplied for a supported request
- Apply it using the workflow required by that generation; some units require compatible diagnostic equipment and a qualified technician
⚠️ Important Warning
Do not guess. Attempt limits and wait behavior vary by head unit. Check the unit documentation or use a qualified technician before repeating an entry.
