When You Need a Mercedes unlock code

After Battery Replacement

The most common reason for needing an unlock PIN. When the battery is disconnected or replaced, the security system activates, requiring your unique PIN to restore functionality.

Unit Removal or Installation

Whether installing a secondhand unit or removing and reinstalling your original stereo, the anti-theft system will require PIN verification upon reconnection.

Electrical System Work

Repairs to your vehicle's electrical system, fuse replacements, or power surges can trigger the security feature, requiring PIN entry to restore your unit.

Anti-Theft Activation

Mercedes units have sophisticated anti-theft protection that activates when power is lost. This security feature prevents thieves from stealing and using your stereo in another vehicle.

How to Find Your Mercedes Radio Serial Number

Step-by-Step Guide:

  1. Obtain removal keys

    You'll need Mercedes removal keys (available at auto parts stores or online) to extract the unit from the dashboard.

  2. Insert keys and remove unit

    Insert the keys into the slots at the corners of the faceplate. When properly inserted, the unit will release from the dashboard mount.

  3. Locate the serial number

    The serial number is typically found on a label on the top, side, or back of the unit. You don't need to disconnect any wires to see it.

  4. Identify the correct number

    The serial number will usually start with letters that identify the manufacturer (e.g., AL for Alpine, BE or BP for Becker).

Serial Number Format Examples:

Alpine Units:
  • Format: ALxxxx followed by numbers
  • Examples: AL2910X0505900, AL2199X1234567
Becker Units:
  • Format: BE or BP followed by numbers
  • Examples: BE2060X1231234, BP0526A6326431
Bosch/Blaupunkt Units:
  • Format: Various formats with BP or BO prefix
  • Examples: BP5001X1234567, BO1150X9876543
Pro Tip: Take a clear photo of the label before reinserting the radio. This saves you from having to remove it again if you need the code in the future.

How to Enter Your Mercedes unlock code

For Standard Audio Systems:

  1. Turn on ignition

    Turn your ignition to position "1" or "ACC" and make sure the display shows "CODE" or similar message.

  2. Use numbered buttons

    Enter each digit of your PIN using the preset buttons (1-4 or 1-10, depending on your model).

  3. Confirm entry

    Press and hold button 6 (or the # button) to confirm your PIN entry.

  4. Wait for confirmation

    The display will briefly show "OK" or similar message, then normal operation will resume.

For Comand/Touchscreen Systems:

  1. Wait for entry screen

    Modern Comand systems will automatically display a PIN entry screen after power loss.

  2. Use on-screen keypad

    Enter each digit of your PIN using the touchscreen keypad that appears.

  3. Press confirm

    Tap the confirmation button (usually labeled "OK" or with a checkmark) on screen.

  4. System reactivation

    The system will process your PIN and automatically reactivate if correct.

Important Warning

Most Mercedes units allow only 3 incorrect attempts before temporarily locking. After 3 failed attempts, you'll need to leave the ignition on for up to 60 minutes before trying again. Some newer systems may require dealer intervention after multiple failed attempts, so ensure you have the correct PIN before entry.

Frequently Asked Questions

Your unlock code is delivered instantly after completing your purchase. The PIN appears directly on your screen and is also sent to your email address for backup purposes. Our automatic system operates 24/7, so you'll never have to wait - even on weekends or holidays.

No, you don't need your Vehicle Identification Number (VIN). Our service only requires the serial number, which can be found on a label on the back or side of the unit. This makes our service especially valuable for secondhand purchases or vehicles without accessible documentation.

We provide a 100% Money-Back Guarantee if our PIN doesn't work. In the unlikely event that the code we provide doesn't unlock your unit, simply send us video proof showing the entry with the serial number visible in the same video, and we'll process your refund immediately. Our success rate exceeds 99% for all Mercedes systems.

Mercedes unlock codes are typically 4 or 5 digits, depending on the model and year. Some specialized systems may have longer PINs. Our service automatically determines the correct format for your specific unit based on the serial number you provide, so there's no need to worry about the length.

While some Mercedes dealerships may provide the unlock PIN if you're the original owner with all documentation, they typically charge a service fee ranging from $80-$150 and require proof of ownership, scheduling an appointment, and possibly leaving your vehicle with them. Many dealers also need the VIN number, which is problematic for secondhand installations. Our service is 85% cheaper than dealership prices and provides the code instantly without appointment delays.

If your Mercedes stereo repeatedly asks for a PIN after you've entered it correctly, there may be an electrical issue causing power interruption to the memory. Common causes include: loose battery terminals, faulty ground connection, damaged connection pins, or a failing unit. In rare cases, the internal memory may be corrupted. Check all electrical connections first, and if the problem persists, our code will still work once the electrical issue is resolved.
