How can I find the code for my Harman radio?
If you have not lost the Harman code yet, check these places first - many vehicles ship with the code written down somewhere in the car.
- Glovebox - Many manufacturers ship a small sticker labelled "Anti-theft unlock code" inside the glovebox door or top panel.
- Owner's manual - Often handwritten on the inside cover or stapled to the page covering the radio.
- Code card - A small slip of paper inside the original purchase pack - sometimes inside the radio sleeve itself.
- Service records - Dealers sometimes write the Harman radio code into the maintenance log after a battery service.
- Old paperwork - Previous owners often leave the code in the document folder, especially on second-hand cars.
- Dealer paperwork - The original window-sticker pack or sales folder sometimes lists the radio code.

The 100% easiest and cheapest way to unlock your Harman radio.
Main Dealer Option (Slow & Restricted)
One way to get it is by contacting an authorized car dealership or vehicle manufacturer service center.
However, because they lookup codes based on the vehicle, they typically ask for your VIN, official proof of ownership, and car registration documents, along with a registration certificate.
The process is frequently slow. Some charge an expensive diagnostic fee, while others offer it for free - but it can take hours, days, or require a physical appointment.

How to Enter the Security Code
Most factory radios can be unlocked in less than a minute after entering the correct code.
When the anti-theft system is active, the radio will lock out all audio features and ask for the unlock code immediately.
The Code Input Process Explained:
Depending on your specific Harman unit interface, use the preset buttons, touchscreen keypad, or numbered controls to select the correct numbers one by one:
- For radios with a standard 1-6 preset button row: Many classic radios do not let you type numbers directly if the code contains digits higher than 6 (like 7, 8, or 9). Instead, you must press a single preset button repeatedly to cycle through digits. Press button 1 multiple times to change the first character, button 2 for the second character, button 3 for the third, and button 4 for the fourth.
- Direct keypad entry method: Simply tap the corresponding numbers directly on the display screen or use the full 0-9 physical dial pad to type the sequence.
⚠️ The Security Lockout Penalty:
Some systems lock out input options for 30 to 60 minutes, during which the vehicle ignition and radio power must remain continuously switched ON to let the timer count down.
If you're unsure how to confirm the code or navigate your specific hardware layout, check your original radio manual or contact our support team.
How to Find the Serial Number on Your Harman Radio
By Removing the Radio Unit (Most Reliable Method)
For most factory-installed and aftermarket radios, the serial number is printed on a physical label attached to the top, side, or rear of the radio unit casing.
To access it, you'll usually need to slightly pull the stereo out of the console. Depending on the vehicle and radio model, this may require radio removal keys:
- The serial is normally printed near a barcode or QR identification label
- The serial typically contains 8-14 characters
- Only the unique serial number sequence works for code generation
Harman chassis label - serial begins with T00 prefix
T00AM serial label on MyGIG NTG4 (top of chassis)
Uconnect VP4 940 board - Alfa Romeo / Fiat
On the Radio Display (Display Method)
Some newer infotainment systems and specific factory units allow the serial number to be displayed directly on-screen using a hidden service menu or a specific button combination.
Harman-specific: Most Harman Uconnect / MyGIG units display the serial directly when locked - the "ENTER CODE" screen often shows the serial above the keypad. On non-touchscreen MyGIG REN/REP press the bottom-left CODE soft key to reveal it. If the screen stays blank, the radio must be removed and the chassis label read.
- Try holding preset keys 2 + 6 while switching the radio on
- A diagnostic screen can reveal the S/N
- Button combinations vary depending on the radio family
Please note that older cassette decks, basic CD players, and most aftermarket retail units do not support on-screen serial retrieval.
Harman Serial Number Examples
Each manufacturer uses its own serial structure and label style.
Below are some common examples found on Harman radios:
- The first characters often identify the radio platform or production series
- Serial formats vary, but they are typically alphanumeric
- Certain digital units show the S/N through a hidden menu
- Classic units often require radio removal to access the serial sticker

Harman serials are typically 10-13 characters - a 3-5 letter prefix followed by 5-8 digits. The full string including the prefix is required for the unlock code lookup.
Serial structure can change across regions, production years, and hardware generations. Entering the wrong serial may generate an incorrect code.
The Difference Between the Serial Number and Part Number
The Serial Number (S/N):
- This is the radio-specific identification number
- It's used to generate the correct unlock code
- Usually located near manufacturer prefixes
The Part Number (P/N):
- This identifies the manufacturer product type
- It's used for technical identification, but not for generating the unlock code
- They may look similar to the serial but cannot unlock the radio
About Harman Radios
Harman International (Samsung subsidiary since 2017) is the largest factory-radio supplier for the Chrysler / Stellantis family. Its MyGIG NTG4 platform powers Chrysler, Dodge, Jeep and RAM head units from 2008 onwards, and the Uconnect 8.4 RA4 / RJ4 / VP4 generation extends across North American and EMEA models including Alfa Romeo and Maserati. Harman serials almost always begin with the "T00" prefix (T00AM, T00BE, T00MD, T00MG) or a "TQN" / "TZ1AA" / "TM9" pattern on later VP4 boards.
Factory radios produced by Harman can be found in a wide range of vehicles and infotainment systems.
Depending on the production year and vehicle model, these radios may appear under different brand names while sharing the same underlying hardware.
Each Harman unit can usually be identified by a unique combination of letters, numbers, and production prefixes.
Serial structures are not universal and can change across different radio platforms manufactured by Harman.
Some Harman radios allow the serial number to be displayed directly on-screen.
However, many units still require checking the identification label attached to the radio chassis.
To ensure an accurate radio code lookup, always enter the complete serial number exactly as shown.
Two visually similar radios can use completely different code databases depending on the serial format.

Frequently Asked Questions
If our lookup form does not recognize your entry, it is usually due to a slight typo or confusing specific characters.
Please make sure to avoid these frequent mistakes:
- Confusing Letters and Numbers: Make sure you aren't swapping the letter "O" with the number "0", or the letter "I" with the number "1".
- Using the wrong reference number: Our system strictly rejects part numbers or hardware codes. Make sure the sequence you enter is the unique serial identifier.
- Including Spaces or Dashes: Enter the serial without any separators - no dashes, no spaces, no special characters.
A countdown timer or a locked message indicates that the wrong radio PIN was entered too many times.
Depending on the exact Harman model, the solution varies.
Temporary Lockout: Keep the stereo powered on for about an hour without touching any buttons. Once the waiting period ends, the display will change back to the "CODE" or "0000" input prompt.
Permanent Lockout Status: If the system reaches its maximum entry limit, it may lock completely. For "LOCKED 10", you can often hold the preset button 6 for several seconds to get a final attempt. However, if it shows "LOCKED 13", the radio is fully locked and may require professional hardware service.
Yes, we provide unlock codes for the entire range of Harman audio systems, including factory warehouse models and retail units.
As long as the radio uses a standard factory anti-theft security system and has a valid, recognizable serial number sequence, our generator can find the matching unlock PIN.
A scratched or unreadable barcode label does not mean your radio is permanently locked.
In almost all cases, the manufacturer stamps the primary serial number directly into the side or rear metal frame of the stereo housing.
Carefully check the metal surface for an engraved code. This stamped number is permanent and will work perfectly in our lookup generator even if the paper label is gone.
Unfortunately, the VIN will not work here. The unlock code is generated using only the unique Harman serial number found on the device itself.
Why is this better for you?
If your radio was replaced by a previous owner, came from a second-hand car, or was upgraded later, a VIN-based code from a dealer will not work.
By using the device serial number, you guarantee that you get the correct code for the exact stereo hardware you own.
