Is your Honda Odyssey radio asking for a code after a battery change or disconnect? You’re facing a common security feature that’s supposed to protect your radio from theft, but can be frustrating when you just want to listen to your favorite station. I’ll walk you through exactly how to get your radio working again, with specific solutions for every Odyssey model year from 1995 to present.
What is a Honda Odyssey Radio Code and Why Do You Need It?
A Honda radio code is a 5-digit security feature that locks your radio when it loses power. Think of it as an anti-theft measure that kicks in when your battery dies or gets disconnected. When this happens, your radio display will show “CODE” or “COdE” and won’t work until you enter the correct digits.
The good news? You have several ways to retrieve this code, and newer models even have workarounds that don’t require the code at all.
Check These Places First for Your Radio Code
Before trying more complex methods, look for your radio code in these common locations:
- Open your glove compartment and look for a small white sticker with a 5-digit number
- Check the side wall inside your glove box
- Look through your owner’s manual wallet or information packet
- Check the radio information card that came with your vehicle
Many Honda owners discover their code has been hiding in plain sight all along!
Quick Solutions by Odyssey Model Year
2018-Present Odyssey Models: Auto-Reset Feature
If you own a newer Odyssey, you’re in luck! These models have an auto-reset function:
- Turn your ignition to ON (don’t start the engine)
- Turn your radio ON
- Hold the power button for 2-3 seconds
- The radio should automatically unlock itself
This feature means you don’t need to hunt for codes or serial numbers for most recent models.
2015-2017 Odyssey Models: Power Button Bypass
These model years offer a convenient workaround:
- Turn your ignition to ON
- Turn your radio ON (it will display “CODE”)
- Hold the power button continuously for 30-60 seconds
- Your radio should reset and start working
If it doesn’t work the first time, try again. Some units need multiple attempts.
2011-2014 Odyssey Models: Mixed Solutions
For these years, try the power button bypass first (as described above). Many 2013-2014 models don’t actually require radio codes and will reset automatically.
If the bypass doesn’t work, you’ll need to use the serial number method described below.
2001-2010 Odyssey Models: Serial Number Method
These older models require retrieving your radio’s serial number:
- Turn ignition to ON position
- Turn radio ON and verify it displays “CODE”
- Turn radio OFF
- Press and hold preset buttons 1 and 6 simultaneously
- While holding buttons 1 and 6, press the Power button
- The display will show your serial number
The serial number might appear as one 8-digit number or as two separate screens displaying “U” numbers and “L” numbers (ignore the letters, just note the numbers).
1995-2000 First Generation Odyssey: Dealership Visit Likely Needed
The oldest Odyssey models often require physical radio removal to access the serial number. This typically means a visit to your Honda dealership, though you can try the serial number method above first.
How to Retrieve Your Radio Code Online
Once you have your radio’s serial number, you can get your code online:
- Visit Honda’s official code retrieval site: radio-navicode.honda.com
- You’ll need:
- Your vehicle’s 17-digit VIN number
- Radio serial number
- Your zip code
- Phone number and email
Honda will provide your 5-digit code immediately on the website.
Where to Find Your VIN Number
Your VIN (Vehicle Identification Number) is required for online code retrieval. Find it in these locations:
- Driver’s side dashboard (visible through windshield)
- Driver’s side door jamb sticker
- Vehicle registration documents
- Insurance card
Entering Your Radio Code
Once you have your 5-digit code:
- Turn ignition to ON
- Turn radio ON (should display “CODE”)
- Use radio preset buttons 1-6 to enter each digit
- Press button 1 for the first digit
- Press button 2 for the second digit
- And so on until all five digits are entered
- The radio should unlock immediately
Troubleshooting Common Radio Code Problems
Error Messages Explained
| Error Code | What It Means | What To Do |
|---|---|---|
| ERR1, ERR2, ERR3 | Incorrect code entry | Wait for the required time (increases with each error) and try again |
| ERRE (Error E) | Too many incorrect attempts | Disconnect battery negative terminal for 1-3 minutes to reset, then try again |
Serial Number Not Displaying?
If you can’t get your serial number to display using the 1+6 method:
- Make sure ignition is in ON position (not ACC)
- Verify radio is ON first, then OFF before trying the button sequence
- Hold buttons 1 and 6 firmly while pressing Power
- Try multiple times – some units can be stubborn
Code Doesn’t Work?
If the code you found doesn’t work, your radio might have been replaced at some point. The sticker in your glove box would be for the original radio, not the replacement. In this case, you’ll need to:
- Get the serial number from your current radio unit
- Use Honda’s website or contact a dealer for the correct code

How to Prevent Future Radio Code Issues
Save yourself future headaches by taking these preventive steps:
- Write down your radio code and store it in multiple places
- Take photos of any code stickers before they fade
- Use a memory saver device when changing your battery
- Note your code before any maintenance that requires battery disconnection
Radio Problems Beyond the Code
If your radio still won’t work after entering the correct code, you might have deeper issues:
- Battery voltage may be too low for proper radio operation
- Radio fuse might be blown (check your fuse box)
- The radio unit itself could be malfunctioning
- Wiring problems might exist behind the dashboard
If you’ve tried everything and still have issues, it might be time to contact Honda Customer Service at 1-800-999-1009 or visit your local dealer.
Dealing with Navigation System Codes
Some Odyssey models with navigation systems require a separate code for the navigation unit. The process is similar to the radio code, but you’ll need to look for a navigation code specifically. The Honda radio and navigation code website can help with both.
Understanding Different Radio Systems Across Odyssey Generations
Different generations of the Honda Odyssey come with different audio systems. Newer models feature touchscreen displays with Honda’s infotainment system, while older models have traditional button-based radios.
The code entry method varies slightly between these systems:
- Touchscreen systems: Enter the code using the on-screen keypad
- Button-based systems: Use the preset buttons as described earlier
Buying a Used Odyssey Without the Radio Code
If you’ve purchased a used Honda Odyssey and don’t have the radio code, you have several options:
- Look in all the places mentioned above for a hidden code
- Try the power button bypass method (for 2011+ models)
- Use the serial number method to retrieve the code online
- Contact the previous owner if possible
- Visit a Honda dealership with proof of ownership
Honda dealerships can look up your code using your vehicle’s VIN, though some may charge a small fee for this service.
Remember, the radio security system is designed to prevent theft, not to complicate your life. Once you’ve retrieved your code, keep it safe so you don’t have to go through this process again!
