How do I look up my Honda radio code?

If your Honda radio prompts for a security code after a battery disconnect, you can usually find it on a dedicated code card that came with the car or retrieve it through Honda’s official channels using your VIN and the radio’s serial number. If you can’t locate either, a dealership can help verify ownership and provide the code or reprogram the radio.

Where to look for the code

Most Honda models use a 4-digit anti-theft code. Start with the sources that are most likely to contain it in your vehicle’s paperwork and then move outward if needed.

Code card and owner's manual

• The primary source is the radio security code printed on a small card (often labeled “Code” or “Radio Code”) that came with your vehicle. It may be tucked inside the owner’s manual, a folder in the glove box, or a similar packet.


• Some manuals include the code or a label with the code and radio details. Check the manual’s warranty/service section or any a separate code insert.

Locating the original code card or manual can save time and avoid dealership visits.

Other physical locations

• Look in the glove box, center console, or the trunk for a loose page, envelope, or sticker that contains the radio code or instructions to retrieve it.


• In some vehicles, a replacement radio or service kit may include an updated code card. Check any spare keys or service records that came with the car.

If you find nothing, prepare to use dealership or official lookup options.

What to do if you can't locate the code

If the original code card or manual isn’t available, you have several reliable options to recover the code.

Contacting a Honda dealer

• Bring proof of ownership (photo ID and vehicle registration or title) and your VIN. The dealer can look up the code in Honda’s secure records and provide the correct 4-digit code.


• You may be asked to provide the radio’s serial number (S/N), which uniquely identifies your radio unit.


• Some dealers may charge a fee for the lookup or code release, especially if special tooling or database access is required.

Dealerships offer a reliably legal path to recover the code when documentation is missing.

Online or official code retrieval tools

• Honda’s official support channels may offer a code lookup service. You’ll typically need your VIN and proof of ownership, and in many cases the radio serial number as well.


• If the online tool is available for your model, follow the instructions to submit information and receive the code. The process can vary by year and model.

Online options provide convenience but still require verification of ownership and often the radio’s serial number.

How to locate the radio's serial number

The radio serial number (S/N) is often needed to retrieve the code from a dealer or through official tools. There are a couple of common methods, depending on the model and radio type.

Display method (typical for many Honda radios)

• Turn the ignition to ON and power the radio on.


• Press and hold the 1 and 6 preset buttons (or the corresponding combo listed in your manual) for several seconds until the serial number appears on the display.


• Write down the serial number exactly as shown.

If this method doesn’t work on your model, consult the owner’s manual or ask a dealer for the exact steps for your year and radio type.

Alternative and physical checks

• On some vehicles, you may need to remove the radio or access a service label located on the radio housing to read the serial number. If you’re uncomfortable doing this yourself, have a professional assist you.


• In rare cases, the serial number is accessible through a service menu in the car’s infotainment system.

The serial number is a key identifier used by the dealer or Honda support to generate or retrieve the correct 4-digit code.
