There are only 3 ways to get the code. Two are free.

Either register your car on-line with Honda to get the code or go to a Honda dealer.

No, the stereo unlock code cannot be retrieved with the VIN.

You can get the unlock code for free from any Honda Dealer. You will need to give them the stereo serial number from the back of the stereo or written on a card (or possibly the manual) provided when the vehicle was new. If the dealer removes the stereo to retrieve the serial number they will charge around $100.

DANGER: Do not try to enter the code randomly! The stereo will lock out after 10 incorrect attempts.

Usually the stereo code is needed for accessing any kind of function of the stereo.
If the radio code is not located in the owners manual there are other places that might have the code displayed.

Check the fuse panel inside cover or the sides of the glove box door.
(This is where I put the radios code sticker for when I am performing new vehicle deliveries)

A honda dealership would be the only option to make use of this problem.

What the Honda dealership does is find the stereo's serial number then the advisor is able to locate the radio's 4 - 6 digit code.

On some models the serial number is found by holding the #1 and #6 radio preset simultaneously, then hitting the power button.

At this point the radio's display should show the serial number and the radio code can be retrieved by the advisor.

Typically to get the code you have to have the serial number of the unit and call a Honda dealership to get the code. Sometimes in years gone by, there was a credit card sized card that had a sticker with the serial number and code. Sometimes the sticker is even stuck on the owners manual or the inside of the glovebox.

It sound like you are going aftermarket so I would think that the code is not needed as the code was only for the factory radio itself, not the rest of the system (speakers, etc..) Call the radio installer and ask but I don't think you need the code.

Best bet take it to an auto electrician. most are able to reset the stereo's code or know where to get the code from. Other than that contact the stereo manufactorer with the serial number. or use an online code cracker company or even try to find a program that will work out the code for you. (a lot of codes are done from the serial number). in the UK the normal price for supplying the code is about £10.

you will need to pull radio out and retrieve s/n off of stereo. with s/n i can get anti theft code for you. if you need help with removing radio let me know.

no wiring diagram needed go cut a plug from a junk yard and wire it into the cut wires then buy the adapter kit for you car and wire that to the car plug and the radio plug.

If you're looking for the code to program your car stereo, you will need to remove the stereo, and get the numbers off the back side of it. Once you have the numbers from the back of the stereo you will need to call the dealership and have them look up the proper program codes. You will also need your VIN number.
Good luck
