The Unlock Code and the device unit's serial number are listed on the anti-theft ID card that comes with the vehicle. The card is usually placed in the glove box at the time of delivery. Use the Unlock Code listed on this card. For certain models, the dealer may have placed a label with the device serial number on the glove box. ----------------- If you cant find it, you need 3 things

1. Vehicle Identification Number (VIN)

2. Phone Number and Zip Code Information

• For security purposes, we(HONDA) verify ownership by comparing the phone number, zip code, and VIN you enter with those we have on file. Unless you have updated these values through Customer Services, the phone number and zip code will be those on file at the time the vehicle was purchased.

3. Device Serial Number

• you need the radio's serial number. since it is located on the back of the radio. your gonna need the pull the radio to get it.

Then CLICK HERE and enter the information for automated code retrieval.

------------------------------

or you can pull out the radio, take it to the service dept. of a honda dealership and ask them if then can look up the code for you. they might ask you for your vehicles VIN, so you might wanna have that written down.
i always get a marker (Sharpie) and write the code on the top of the radio. that way you can't loose it.

Unless the Accord was jump started, creating possible power surge to damage radio, it should not of had any relationship to the radio.

But, just in case, would suggest disconnecting battery for 5 minutes, reconnecting battery, reentering radio code and see what happens.

If that fails, hopefully your under 36k miles or got the Factory extended warranty "Honda Care" Service plan, so take to the Honda Dealership to see what they say.

FREE and EASY methods to get your Honda radio UNLOCK CODE. (Dealerships usually charge)

Assuming you don't have the Anti-Theft Code and Serial Number that is found on the credit card sized Anti-Theft Radio Identification Card that comes with the vehicle at the time of purchase and is usually found in the glove compartment....

You have FREE options to retrieve that code by phone or on the internet BUT, the RADIO SERIAL NUMBER is REQUIRED (no matter what). (see bottom about removing ERROR E3)

***IF your Honda was made BEFORE 2001 the serial number MAY not be accessible without removing the radio from the vehicle.***

* TO GET THE SERIAL NUMBER (so that you can get the unlock code)

1. Get something to write with and on (you'll need it to write down the serial number)
2. Put the ingnition key in and turn it until your able to turn your radio on (accessories position).
3. Then turn your radio OFF by it's knob/button (but leave the ingition key in place).
4. Hold down the preset buttons 1 and 6 at the same time.
5. Turn the radio on while pressing down both the 1 and 6 buttons.(***IF your Honda doesn't have preset buttons on the radio then hold down the top part of the 'Seek/Skip' button AND the top part of the 'Change Disk' button instead.*** )
6. Write down the 4 numbers you see first and then 4 more that display. These eight numbers are the SERIAL NUMBER. This is NOT your CODE.
7. Make sure your VIN (Vehicle Identification Number) is handy to get the unlock code. (can be found on your insurance card, driver's side door jam, small plate on dashboard by registration and inspection stickers, etc)

* TO GET THE UNLOCK CODE (using the radio Serial Number and VIN)

---Internet option:

1. Go to https://radio-navicode.honda.com/ (YES, it's run BY HONDA and IT'S FREE)
2. Follow on screen instructions (Serial Number and VIN required)
3. Type in the 5 digit code into your radio. This will unlock the radio and return it to a functional state.

-OR-

---Telephone option:

1. Call American Honda Customer Relations (800) 999-1009
2. When the automated message starts 'Press 3' for 'Radio and Navigation Codes'.
3. Tell the Customer Service Agent you need your radio code. (They will ask for your name, your radio's serial number, VIN, etc)
4. When they give you your radio unlock code--WRITE IT DOWN and KEEP IT SAFE!

* REMOVING ERROR E3

****If you entered too many wrong codes and got an ERROR E3 message displaying you'll need to do an additional step for even the correct unlock code to work.****

Disconnect your negative battery terminal (or pull the radio fuse out if that's easier for you) for 30 seconds then reconnect it and then the radio will say "CODE" again and you can put in your correct unlock code.

If the power from your battery to the Honda radio is interrupted the Anti-Theft feature kicks in, the radio is rendered inoperable and the screen reads 'CODE'. You must enter in the Anti-Theft Radio Unlock Code (usually 5 digits) to make it operational again. You know that much by now.

If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle. If this card is lost, you must obtain the audio unit serial number in order to get the radio code. Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio (some people say that they find the code on a sticker in the glove compartment, but I wouldn't count on that). Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The number will come up in two sets)
Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.
Hope this helps you.
