If you need a code for your stereo or radio in your car.

your best bet is that there maybe a 5 digit number in your glove compartment ..if there isn't there maybe a longer digit number in that case you need to call a dealership and ask them for a radio code and just follow what they tell you to do

call your local dealership , they will give it to you.
You may need to pull the stereo to get the serial number though.

It's different for each individual car. If you go to your local Honda Dealership they can look it up for you. They will need the VIN to get the code for your specific car. Bring your insurance card, registration, and photo ID to prove ownership.
Be sure not to write it down inside the car. Not the owner's manual or anything else kept inside the car.
The radio code is a form of anti theft. Keep the code at home or on you computer.

You need to pull the stereo out to get the stereo serial# and then go to the dealership with your driver license along with your car registration. You need to go to service station and they'll get the stereo code# to you. Some dealership they might keep the stereo code in their data bank, so just show them your car registration where they can get your VIN# and they'll get the code# for you.

You have the wrong stereo code. No Honda stereo code has a 0.Your local dealership parts dept. should be able to supply the stereo code given the VIN of the vehicle or serial number of the stereo.
