How to Find the S/N on a Sprinter's Radio
The only thing you'll need to get the code is your radio's serial number (not part number!).
On all Mercedes's, you can find it in one of these places:
- Displayed on the radio screen (by using some combinations of buttons)
- On the radio body itself - you'll need to extract it and write down serial (which is not so hard).
Search for something like: Serial, SN, S/N, Serial Num...
1. Find the S/N on Mercedes Sprinter's Display
Unfortunately, on Mercedes Sprinter radios the serial number is not shown on the screen.
In that case, you'll need to take out the head unit and check the sticker on the side of the radio.
2. How to Find the Serial Number on the Radio Unit's Sticker
The serial number is usually printed on a label attached to the radio casing.
Step 1: Turn off the car.
Step 2: After that, take off the surrounding panel.
Step 3: Then unscrew the radio brackets.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables).
Step 5: Look for the serial number on the rear of the unit.
Step 6: Write down the full S/N carefully and come back to our website so that we can generate your code.
Important: Don't mix the Serial Number from the Part Number!

Mercedes Sprinter's Most Common Radio Code Triggers
Many owners encounter radio code issues on their Sprinter after electrical work.
Below are the most frequent situations when this can occur.

This security feature is designed to prevent theft by disabling the radio after electrical reset.
Other Situations That Trigger a Radio Code on Mercedes Sprinter
- Installing a used head unit will require the original radio code.
- After an ECU or software reset, the radio may lock.

Quick Fixes Before Paying for a Radio Code
Before you pay for it, it's worth checking a few places where the code is often stored.
Some owners find their Mercedes Sprinter radio code without needing any tools or paperwork.
Here are the easiest things to check first.
Check the Car and Its Documentation
- In the owner's manual, often on a code card.
- Inside the glovebox, sometimes on a small card.
- In the boot compartment, on a radio label.
- In your car paperwork from the previous owner.
- On the head unit itself, if it was removed before.
Can the Dealer Get You the Code?
Dealerships can retrieve your radio code by checking the vehicle records in their system.
They typically ask for registration and ID before sharing the security PIN.
This is the official way to restore access to the factory radio.
Downsides:
- Some imported or older radios may not be in their database.
- You may need to contact service support during business hours.
- The lookup is often not instant and may require waiting.
- Dealers frequently charge a service fee (It may cost more than 100$).

You've Got the Code. How to Enter It?

Based on the radio, use control knob, touchscreen, or radio presets to set each digit, then submit the code to restore radio functionality.
Try not to make mistakes, because too many wrong attempts can disable your radio temporarily.
It allows a few incorrect tries before showing a LOCKED message.
You can reset the lockout by keeping the ignition on for an hour or a set waiting period.
