How to Reset a 2010 Honda Radio

To reset a 2010 Honda radio after a power loss, you typically need to enter a five-digit anti-theft code. You can retrieve this code from Honda using your radio’s serial number (shown on the unit or on-screen via a button sequence) and your VIN. Once you have the code, turn the ignition to ON, power the radio, and input the digits using the preset buttons or touch screen, depending on the model. Below is a detailed guide covering both standard and navigation-equipped systems, how to get the serial number, where to obtain the unlock code, and what to do if the radio is locked with an error message.

Why Honda Radios Ask for a Code

Many 2010 Honda models include an anti-theft feature that disables the audio system when power is interrupted (for example, after battery replacement or a jump-start). The radio then displays “CODE” and requires the unique unlock code tied to that unit. Entering incorrect codes repeatedly can trigger an “ERR” or “LOCKED” message, pausing further attempts for a period.

What You’ll Need Before You Start

Gather the following items to streamline the reset process. Having these on hand helps you retrieve the code quickly and avoid multiple trips between the car and a computer or phone.

• VIN (vehicle identification number), visible on the driver-side dashboard or your registration/insurance.
• Radio serial number (pulled from the radio’s display or via a diagnostic menu, described below).
• Access to the Honda owner site or a phone to contact a Honda dealer.
• Proof of ownership (some dealers require ID and registration).
• Stable vehicle power (engine running or a battery maintainer) to prevent shutdown during the process.

With these items ready, you can obtain the unlock code online or through a dealer and complete the reset without interruptions.

Find the Radio Serial Number

For standard (non-navigation) radios

Most non-navigation head units can display their serial number using a built-in key combination. Follow these steps at the vehicle, ideally with the engine running to ensure stable voltage.

1. Turn the ignition to ON (II). Ensure the radio is powered off.
2. Press and hold preset buttons 1 and 6 simultaneously.
3. While holding 1 and 6, press the radio power button. Keep holding until numbers appear.
4. Note the serial shown. You may see either an 8-digit number or two identifiers such as “U####” and “L####.” If you see U and L lines, combine them (UxxxxLxxxx) to form the full serial.

Record the serial exactly as displayed. You’ll use it to retrieve the unlock code from Honda.

For navigation-equipped models (factory NAV/audio units)

Navigation-integrated audio units use a diagnostics screen to reveal system details, including the radio serial number. The wording may vary slightly by model year and unit software.

1. Turn the ignition to ON (II) and power on the navigation/audio unit.
2. Press and hold the Menu, Map/Guide, and Cancel buttons together for several seconds to open the Diagnostic or Detail Information screen.
3. Select options such as Unit Check, Version, or System/Device Information.
4. Locate and note the Audio or NAVI serial number exactly as shown.

Write the serial down carefully; you’ll need it to obtain the correct unlock code associated with that specific unit.

Get Your Unlock Code from Honda

With your VIN and radio serial number, you can retrieve the code through Honda’s official channels. The process is typically quick and automated for U.S. vehicles; other regions offer similar owner portals.

1. Visit Honda’s owner site (U.S.): owners.honda.com and navigate to Radio/Navi Code resources.
2. Enter the requested information: VIN, radio serial, and contact details (Honda may verify ownership).
3. Receive the five-digit anti-theft code. Save it in your records.
4. If online retrieval isn’t available or you’re outside the U.S., contact your local Honda dealer or your regional Honda owner site (e.g., Honda Canada) with VIN, radio serial, and proof of ownership.

If you have a code card or a sticker in the glove box/owner’s manual labeled “Anti-Theft” with a five-digit number, that may already be your unlock code. Verify digits carefully before entering them.

Enter the Code to Reset the Radio

Once you have the correct code, entering it restores functionality immediately. The method differs slightly by head unit type.

1. Turn the ignition to ON (II). Ensure the radio displays “CODE.”
2. For non-navigation radios: Use the preset buttons to enter the five digits (e.g., press “1” for the first digit, “2” for the second, and so on). If a digit is zero, use the “0” button if present.
3. For navigation units: Use the touch-screen keypad (or on-screen prompts) to input the five-digit code.
4. The radio should power up normally once the fifth digit is entered. If it doesn’t, double-check the code and try again.

After successful entry, set your presets and clock. Keep the code stored in a secure place for future use (e.g., after battery service).

If You See “ERR” or “LOCKED”

Too many incorrect attempts can temporarily lock the unit. Most 2010 Honda radios allow you to clear the lockout with time and stable power.

• Leave the ignition ON and the radio powered on for about 60 minutes without interruption. The display should revert from “ERR” to “CODE.”
• Avoid repeated guesses; each failed attempt can extend the lockout period.
• Ensure constant power during the wait (engine running or a maintainer) to prevent resets that restart the timer.

Once “CODE” reappears, enter the correct five-digit code. If the unit remains locked or behaves inconsistently, consult a Honda dealer to verify the serial and code or check for head-unit faults.

Can’t Find the Code? Here Are Practical Options

If the online portal can’t verify your information or you lack documentation, these routes usually resolve it.

• Check for a factory code card or a sticker in the glove box, owner’s manual packet, or service records.
• Contact a Honda dealer with your VIN and radio serial; be prepared to show ID and ownership documents.
• If the head unit was replaced, the code may have changed—your dealer can retrieve the correct code for the current unit.

Most owners can recover the code the same day via dealer support, especially when the serial number is readily available.

Tips to Prevent Future Lockouts

A little preparation helps avoid downtime after future battery work or storage.

• Store the code and radio serial in your phone or maintenance log.
• Use a memory saver when disconnecting the battery during service.
• Keep your Honda owner account updated so code retrieval is seamless if needed again.

These steps save time and prevent repeat lockouts after routine maintenance or unexpected battery issues.

Model Notes for 2010 Hondas

The procedures above apply broadly to 2010 Accord, Civic, CR-V, Fit, Insight, Odyssey, Pilot, Ridgeline, Element, and Crosstour models. Non-navigation radios use the 1+6 power-on method for the serial; navigation units use the Menu+Map/Guide+Cancel diagnostic menu. Entry of a five-digit code is standard across trims.

Summary

Resetting a 2010 Honda radio requires the five-digit anti-theft code tied to your specific head unit. Retrieve the radio serial (1+6+Power for standard units or the navigation diagnostic menu for NAV models), get the code via Honda’s owner site or a dealer using your VIN and serial, and enter the code on the radio. If locked out with “ERR,” maintain power and wait about an hour for it to return to “CODE,” then try again. Keep the code and serial stored to make future resets painless.
