The Complete Guide to Retrieving Your Honda Radio Code

If you’ve recently disconnected your Honda car battery, had electrical work done on your vehicle, or purchased a used Honda, you may find yourself staring at a radio that’s asking for a code. This security feature in Honda vehicles prevents theft but can be frustrating when you need to unlock your radio. This comprehensive guide will walk you through every method to retrieve your Honda radio code quickly and efficiently.
Why Does My Honda Radio Need a Code?
Honda implemented the radio code security feature to deter theft. When the battery is disconnected or power to the radio is interrupted, the radio enters a locked state and requires a unique numeric code to function again. This makes stolen Honda radios essentially worthless without the corresponding code, reducing the incentive for theft.
If your Honda radio is specifically asking for a 4-digit code, this is the most common format for Honda vehicle security systems. For detailed instructions on handling this specific scenario, check out our comprehensive guide on what to do when your Honda radio asks for a 4-digit code.
Where Can I Find My Honda Radio Code?
Important: Before trying more complex methods, check these easy locations first. Many Honda owners discover their radio code was provided with their vehicle documentation.
Method 1: Check Your Vehicle Documentation
The simplest place to find your Honda radio code is in your vehicle documentation. Honda typically provides the radio code on a small card that’s included with your owner’s manual or maintenance booklet. Look for a card labeled “Anti-theft Radio Code” or something similar.

Method 2: Inspect the Glove Box
Honda sometimes places a sticker with the radio code inside the glove compartment. Open your glove box and look for a small sticker with a series of numbers. This might be your radio code.
Method 3: Check Under the Hood
Some Honda vehicles have the radio code written on a sticker under the hood. Look for a sticker on the radiator cover or elsewhere in the engine compartment.

Method 4: Using Your Vehicle’s Serial Numbers
If you can’t find your radio code in the documentation, you’ll need to gather some information from your vehicle:
- Locate your radio’s serial number. This typically requires removing the radio from the dashboard. The serial number is usually on a sticker on the side or back of the unit.
- Find your vehicle’s VIN (Vehicle Identification Number). This 17-character code is located on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb.
- With these two numbers, you can contact Honda customer service or visit a dealership to retrieve your code.

Method 5: Using the Radio’s Preset Buttons
For some older Honda models, you can retrieve the radio code using a sequence of button presses:
- Turn on the ignition to the “ON” position (don’t start the engine).
- Turn on the radio and wait for “CODE” to appear on the display.
- Press and hold the #1 and #6 preset buttons simultaneously.
- While holding these buttons, press the power button.
- The display should show a 10-digit serial number. Write this down along with your VIN.
- With this information, you can retrieve your code online or from a dealer.

How to Enter Your Honda Radio Code
Once you have your radio code, entering it is straightforward:
- Turn your ignition to the “ON” position.
- Turn on your radio. It should display “CODE” or “ENTER CODE”.
- Use the preset buttons to enter the digits of your code. For example, if your code is 12345, press preset button 1, then 2, then 3, and so on.
- After entering all digits, your radio should unlock and function normally.
Caution: Most Honda radios lock temporarily after several incorrect code attempts. If this happens, leave the radio on for about an hour and try again.
Troubleshooting Common Honda Radio Code Issues
Even with the correct code, you might encounter some issues when trying to unlock your Honda radio. The most common problem is seeing an “Error E” message on your display after entering the code incorrectly too many times. This security lockout can be frustrating, but it’s easily fixable. For a detailed solution to this specific problem, visit our guide on how to fix radio code Error E the easy way.
Other common issues include the radio not accepting any input after multiple failed attempts, or the display showing garbled characters. In most cases, these problems resolve themselves after waiting for the lockout period to expire, typically one hour with the radio powered on.
