Retrieve Your Mercedes Radio Code Online
Locked Mercedes radio after a flat battery, battery change or radio removal? We can help you recover the correct security code using the serial number printed on your radio label.
This service is useful for many original Mercedes units, including Becker, Bosch, Audio 10, Audio 20 and COMAND systems fitted in models such as C-Class, E-Class, A-Class, Sprinter, Vito, ML and more.
Enter Your Mercedes Serial Number
Use the serial or part number printed on the radio label. Mercedes labels may show numbers like A 166 900 96 19, BE, AL or Bosch formats.
Check SerialTip: check the top, side or back label of the radio unit. A clear label photo helps avoid mistakes.
How to Find Your Mercedes Radio Serial Number
For most Mercedes radios, the serial number is printed on a sticker attached to the unit. You may need to remove the radio slightly from the dashboard so you can read the label clearly. Look around the barcode area, the side label or the top label.
Mercedes used different radio manufacturers over the years, so the label format is not always the same. Some units show a Mercedes part number such as A 166 900 96 19, while Becker, Bosch or Alpine radios may show their own manufacturer serial.
Mercedes Radio Asking for Code?
If your Mercedes radio shows CODE, ENTER CODE, WAIT or a similar message, it usually means the unit has lost power and needs the original security code again. This often happens after replacing the battery, disconnecting the battery, buying a used car or removing the radio.
Before ordering
Check the serial number carefully and take a clear photo of the label if possible. Mercedes radio labels can contain several numbers, but the correct one is usually near the barcode, manufacturer name, model number or part number.
Avoid random attempts. Too many wrong entries can make the radio display WAIT or lock the unit for longer.
Mercedes Models We Can Help With
Our Mercedes radio code service can help with many factory radios used across popular Mercedes-Benz vehicles. The most important detail is always the serial number from the radio label.
Common Mercedes Radio Types
Mercedes did not use only one radio type. This is why checking the label is so important. A Sprinter radio code may use a different serial format from a C-Class, E-Class or Vito unit.
Mercedes Becker Radio Code
Becker radios are very common on older Mercedes models. These labels often include serials beginning with BE, followed by letters and numbers.
Mercedes Bosch Radio Code
Bosch units are found on some Mercedes factory radios and navigation systems. The label may show a Bosch number, Mercedes part number and other production details.
Audio 10, Audio 20 and COMAND
Many Mercedes radios are marked as Audio 10, Audio 20 or COMAND. The exact code route depends on the unit fitted in the car, so the full label is always useful.
