    Hello. I am having the same problem now for my honda 2002 Accord. I replaced the battery. Where do you find the code or retrieve the code from. And have you found out how to reset the system. I am going crazy without the radio. Thanks

    Once the incorrect code has been entered three times, the radio will enter into a lock mode. To reset the lock mode, leave the radio powered up and turned on for at least one hour. It should then reset and allow you to enter the correct code.

    Unlock 2004 Honda Accord EX radio

    My car battery died, I had it jumped and restated, then I found the radio locked with the message 'COdE'.
    I managed to unlock it (for free) by taking the steps outlined below. As there are likely other methods, this worked for me, and my radio plays once again.

    Instructions
    Things you will need:
    • Ignition key
    • Pliers or related tool (Removal of fuses if necessary, very easy)
    • Radio code (YOU MUST HAVE THIS)*

    *If you don't have the radio code
    1. Place ignition key in the accessory position
    2. Press and hold preset buttons 1, 6 and the power button (all at the same time)
    3. A 'U' will appear followed by 4 digits (write them down)
    4. An 'L' will appear followed by 4 digits (write them down)
    5. These 8-digits make up your radio's serial number
    6. Go to https://radio-navicode.honda.com/
    a. This is a Honda site and is free
    7. Enter your VIN
    8. Enter the phone number and area code that are registered to your car
    a. Most likely the phone number and area code given during the purchase of the vehicle (i.e. on the paperwork)
    9. If successful, you will need to enter the 8-digit serial number from step 5
    10. The site will provide your radio code (WRITE IT DOWN AND SAVE IT)

    Once you have all required materials, follow these steps:

    Step 1
    Once you see 'COdE' simply type the radio code by using the preset button numbers.
    If successful, the radio will beep and you are done!

    Step 2 (If Step 1 unsuccessful)
    Try it again, you have up to 9 more attempts (10 total) to enter the correct code, so make sure you are typing it in correctly. You may also want to verify the radio code by repeating the 'If you don't have the radio code' section above.
    If you fail on all attempts the radio will lock and you will no longer see 'COdE' when turning the radio on. You will now see something like 'ERR'.
    This means that the radio is locked and will need reset.

    To reset (use either option until you succeed):
    Option 1:
    Remove the negative terminal from the battery and let the system reset; reconnect the negative terminal. The radio should now display 'COdE' again. Repeat Step 1.

    Option 2:
    Remove the radio fuse from the internal fuse box (fuse diagram is on the fuse box cover).
    Remove the 'Backup' fuse from the fuse box under the hood.
    After keeping both fuses out for a minute or so, replace them where you got them.
    The radio may engage and you will hear the CD player make a noise.
    Your radio should now display 'COdE' again.

    Repeat Step 1 and hope for the best

    I want to thank you Bradshire, and hope you get this message. We have had a recurring problem with corrosion on the battery terminals, so jump starts are recurrent. This time, there was only the 'err 2' message on the radio. [No clue what hubby did or tried to do.] I've since lost the code and thought I would have to spend way too much time at the dealer's getting this resolved. Also with money I did not want to spend on a silly problem. To make a long story longer, I would kiss you if at all possible! Your solution was exact and precise.Saturday morning we are picking up a puppy that is being transported from Kentuckey/Tennessee and though it's just an hour away, we wanted to be playing some inspirational tunes going and coming. Thank you, thank you!My 12 yr old and I adore you and your smarts!

98 honda accord audio "CODE e" [ 3 Answers ]

I replaced the battery on my Honda. Well the audio system disengaged and required a 5 digit code to reset. I obtained this code from the dealer. I entered the 5 digit code and nothing happens except shows "CODE e". The manual has little to say about this.. Anyone know?
