How Do I Unlock My Honda Car Stereo?

Updated March 13, 2018

Stereos in most Honda vehicles are equipped with an antitheft radio code. If your car battery dies, the radio is disconnected or the battery is disconnected, you will have to enter the antitheft radio code into the stereo before it will work again. If your stereo is locked, try a couple of methods to unlock the stereo.

Find the antitheft card that was issued with your vehicle. The card is about the size of a credit card and usually says “Anti-Theft Radio Identification Card.” It will come with two stickers with two sets of numbers. It is usually located inside the glove box.

Locate the stereo unlock code on the stickers. The code is the set of numbers that is five digits. The other set of numbers and letters is the serial number for your stereo.

Turn the ignition switch in your vehicle to on. “CODE” should show on your Honda stereo once the ignition is on.

Use the “Tune” knob on your stereo to enter the antitheft radio code. Turn the knob to scroll through the numbers. Press the knob when you are on the correct number. That number will lock in, and then you can enter the second number and so on. Most models only require the first four numbers of your antitheft code. Once you have those entered, the radio should turn on.

Make sure you put in the correct code. If you put in an incorrect code more than three times, the stereo will lock you out for 24 hours.

Go to Honda’s Radio and Navigation Codes website if you cannot find your antitheft radio identification card. Click “Continue” to get to the first page.

Enter your Vehicle Identification Number or VIN when prompted. The VIN is 17 digits and is found at the bottom of the windshield on the driver’s side.

Click “Continue” and follow the prompt to enter your phone number and Postcode. You must enter the phone number and Postcode that are on file with the dealer. If you haven’t changed them, the information is the same as when you purchased the vehicle.

Choose “Continue” and move onto the page to enter your radio serial number. On 2001 and later vehicles, you can find your serial number by pressing and holding the numbers “1” and “6” on your stereo while the vehicle is off. Turn the stereo on and watch for two sets of numbers. The screen will switch between one set of numbers and the second. Each number will start with a letter. Don’t worry about the letter and write down both sets of numbers. That is your serial number. For models earlier than 2001, you will have to get the serial number off the back of the stereo. If you don’t know how to take the stereo out, you will have to take your vehicle to a dealer.

Enter the radio serial number when prompted. Once you’ve entered the correct information, Honda will provide you with your radio unlock code. Enter it as directed in the first section.
