How can I find the code for my Alpine radio?
If you have not lost the Alpine 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 Alpine 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.

How to Find the Serial Number on Your Alpine Radio
By Removing the Radio Unit (Standard Method)
On most OEM and retail units, the serial number is printed on a physical label attached to the back or side 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:
- Look for a white, silver, or yellow sticker labeled "Serial," "S/N," or containing a barcode
- The serial typically contains letters and digits with manufacturer-specific prefixes such as "BP" (Blaupunkt), "M" / "V" (Ford/Visteon), "BE" (Becker), or "CL" (Clarion)
- Only the unique serial number sequence works for code generation

On the Radio Display (Without Removing the Unit)
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.
Alpine-specific: Honda and Acura Alpine units reveal the serial through a hidden service menu. With the radio OFF, press and hold preset buttons 1 + 6 (or 2 + 6 on some Civic / CR-V models) while pressing the power button. The serial appears on-screen for 5-10 seconds. Navigation Alpine units (M / K prefix) also accept the INFO + MENU combination.
- Try holding "INFO" + "MENU" while switching the radio on
- Some radios show the serial before the "CODE" screen loads
- Every manufacturer uses different key sequences
This feature is only available on selected digital and factory-integrated models. If nothing appears after trying the button combinations, you'll need to physically remove the radio and check the metal casing label manually.
Common Car Brands That Use Alpine Radio
Alpine is the dominant factory-radio supplier for Honda and Acura - virtually every head unit between 1995 and 2015 in these brands was Alpine-built. Alpine also supplies the Jaguar Premium Sound system, selected Mercedes-Benz models and some Chrysler / Dodge truck radios under the Mopar parts catalogue.
This radio family is used by several car brands.
Common car brands that may use Alpine radios include:
| Car brand | Radio model coverage | Open |
|---|---|---|
|
|
1 radio model indexed | Supported |
|
|
13 radio models indexed | Supported |
|
|
18 radio models indexed | Supported |
|

20 radio models indexed | Supported |
Not every model from these brands will use the same radio family.
How to Enter the Radio Code
Once your radio code is generated, entering it only takes a few steps.
Locked radios typically display messages such as "CODE," "ENTER CODE," "SAFE," or a series of flashing digits.
The Code Input Process Explained:
Depending on your specific Alpine unit interface, use the preset buttons, touchscreen keypad, or numbered controls to select the correct numbers one by one:
- Standard button entry method (No direct number keys): If your unlock code contains numbers like 8 or 0, you use presets 1 to 4 to dial them in. 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.
- For touchscreen or full-keypad models: Type the security numbers exactly as they appear in your delivery email using the integrated dashboard keypad.
⚠️ The Security Lockout Penalty:
Depending on the manufacturer family, the unit will require a strict waiting period before allowing another entry attempt.
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.
About Alpine Radios
Alpine Electronics is the Japanese factory-radio specialist most strongly associated with Honda and Acura. Almost every Honda head unit between 1995 and 2015 was Alpine-built, and Acura premium audio (ELS Studio) is exclusively Alpine. Alpine also supplies Jaguar (Premium Sound), Mercedes (selected classes) and Chrysler / Dodge truck radios. Honda / Acura Alpine serials are 8 characters: a "U" or "M" letter followed by 7 digits (Honda) or an "A" / "K" prefix on Acura units.
Factory radios produced by Alpine 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 Alpine unit can usually be identified by a unique combination of letters, numbers, and production prefixes.
Most serial numbers contain a mix of letters and digits and may vary in length depending on the radio generation.
Certain models include a diagnostic menu that can reveal the serial number without removing the unit.
For older systems, accessing the label on the radio housing remains the most reliable identification method.
The unlock code is generated from the radio serial number, so every character matters.
Radios with the same design may still require different unlock codes if they were produced under different platforms or serial ranges.

Frequently Asked Questions
If the paper sticker or yellow label on your Alpine unit is ripped, faded, or missing, don't panic.
Most major radio manufacturers, including Alpine, engrave or stamp the unique serial number directly into the metal casing of the radio chassis.
Look closely at the metal body of the radio - you will find a stamped sequence (such as a prefix followed by a series of digits) that matches the format of your unit.
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:
- Character typos: Double-check that digits like 0/O or 1/I are entered correctly based on the standard Alpine format.
- Entering the Part Number: Our system strictly rejects part numbers or hardware codes. Make sure the sequence you enter is the unique serial identifier.
- Incorrect formatting: Type the entire serial number as a single continuous string of text without adding spaces, hyphens, or special punctuation marks.
Absolutely. Our system supports original car radios built by Alpine for vehicle brands, as well as aftermarket models purchased separately.
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.
No, the VIN code is not used for this process because Alpine codes are linked directly to the radio hardware, not the car chassis.
This is actually a major advantage:
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.
If your screen displays SAFE, WAIT, or a LOCKED status, the device has entered temporary or permanent protection mode after wrong entries.
Depending on the exact Alpine model, the solution varies.
SAFE / WAIT Mode: Keep the stereo powered on for about an hour without touching any buttons. The countdown timer will reset, and the screen will automatically allow you to enter the correct code again.
LOCKED 10 / LOCKED 13: 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.
