How to Get the Radio Code for a 2003 Honda Accord

You can retrieve the 5‑digit anti‑theft radio code for a 2003 Honda Accord by checking the glovebox sticker or the original owner’s materials, using Honda’s official radio/nav code lookup website with your VIN and the radio’s serial number, or by contacting a Honda dealer with proof of ownership. Below are the exact steps to find your serial number, get the code, and enter it safely.

Where to find the code quickly

Honda often supplied the radio code on a small card or sticker when the car was new. Before doing anything else, check the places where owners commonly find it, as this can save time.

• Inside the glovebox: Look for a white sticker. The top number is usually the 5‑digit “Code,” and the bottom number is the 8‑digit “Serial No.”
• Owner’s manual packet: Check the radio/anti‑theft card or the first pages of the audio/navigation manual.
• Service paperwork: Some dealers record the code on the repair order or maintenance receipt.
• On the radio chassis: If the dash unit has been serviced before, a code sticker may be on the radio body (this requires removing the radio).

If you find a 5‑digit code labeled “Code,” that’s what you need. If you only find an 8‑digit serial, keep it—you’ll use it to retrieve the code online or from a dealer.

Get your radio serial number (without removing the radio)

For standard 2003 Accord radios (non‑navigation)

You can display the radio’s serial number using the front buttons. This avoids removing the unit and works on most factory radios of this era.

1. Turn the ignition switch to ON (II). Make sure the radio is OFF.
2. Press and hold preset buttons 1 and 6.
3. While holding 1 and 6, press the Power/Volume knob to turn the radio ON.
4. The screen will show the serial as an 8‑digit number. Some units show it in two parts (for example, “U1234” and “L5678”). Combine them as 12345678.
5. Write the serial down exactly as shown.

If the display shows two 4‑digit blocks (Uxxxx and Lxxxx), join them to create the full 8‑digit serial. If nothing displays, verify the radio has power and try again.

For factory navigation units (if equipped)

If your 2003 Accord has factory navigation, you can access a diagnostic screen to read the audio/navigation serial numbers. These vehicles typically require the same 5‑digit anti‑theft code, but the serial you need may be labeled as the “navigation” or “audio” unit serial.

1. Turn the ignition to ON (II) and power the system.
2. Press and hold Map/Guide, Menu, and Cancel simultaneously until the diagnostic screen appears.
3. Select “Unit Check” or similar, then locate the Serial Number(s) for the Audio and/or Navigation unit.
4. Write down the serial exactly as shown.

Make note of which serial you captured (Audio or Navigation). The Honda site will ask you to specify the device type when retrieving the code.

Use Honda’s official lookup to get the code (U.S.)

Honda provides a free online tool to retrieve your radio or navigation code. You’ll need the vehicle’s VIN and the device’s serial number. The lookup is available to U.S. owners.

Have this information ready before you start:

• VIN (17 characters), found on the dashboard near the windshield or on the driver’s door jamb, registration, or insurance card.
• The 8‑digit radio (or navigation) serial number you retrieved.
• Your ZIP code and phone number (used for verification; try your current info if you’re not the original owner).
• An email address to receive a copy of the code.

With those details on hand, the process is quick and usually returns the 5‑digit code immediately on-screen and via email.

Step‑by‑step on the website

Follow these steps to retrieve the code online without visiting a dealer.

1. Go to Honda’s official lookup: owners.honda.com/service-maintenance/radio-navicode (the shortcut radio-navicode.honda.com redirects there).
2. Select Honda Automobile, then choose Get Code.
3. Enter your VIN and the radio/navigation serial number, and select the correct device type.
4. Provide the requested ZIP code, phone number, and email, accept terms, and submit.
5. Record the 5‑digit code displayed and save the confirmation email.

If the site can’t validate your info or you’re outside the U.S., move on to dealer or regional Honda support for assistance.

If the website doesn’t work: call or visit a Honda dealer

Any Honda dealership can look up the code once they verify ownership. Many will provide it over the phone or via email if you supply the VIN and the radio serial; some may ask you to visit with documents.

Bring the following to the dealership to streamline verification:

• Government‑issued ID
• VIN and vehicle registration/title (proof of ownership)
• The radio/navigation serial number (photo or written)
• Proof of purchase if the radio was replaced or is salvage

U.S. owners can also call American Honda at 1‑800‑999‑1009 (Automobile Customer Support). Outside the U.S., contact your local Honda customer service or a regional Honda dealer; processes vary by country and may not include an online tool.

Enter the code in your 2003 Accord

Once you have the 5‑digit code, entering it is straightforward. The radio must be powered and showing CODE or ENTER CODE.

1. Turn the ignition to ON (II). Turn the radio on; it should display CODE.
2. Use the radio preset buttons (1–6) to enter each digit of the 5‑digit code.
3. If correct, the radio will unlock and resume normal operation automatically.

If the radio shows ERR or LOC after several failed attempts, leave the radio ON for about 1 hour (vehicle running or on a charger) to clear the lockout, then try again with the correct code.

Troubleshooting and tips

Most problems come down to an incorrect serial, a mismatched VIN, or a lockout from repeated wrong entries. These quick checks resolve most issues.

• ERR/LOC displayed: The unit locked after too many wrong tries. Leave it powered ON for ~1 hour to reset, then re‑enter the correct code.
• Phone/ZIP not recognized online: Try your current info; if it still fails, call a dealer with your VIN and serial.
• Replaced/salvage radio: The needed code is tied to the radio’s serial number, not your car. Provide the replacement unit’s serial to Honda/dealer.
• No serial appears with 1+6: Confirm the radio has power; if needed, have a technician pull the unit to read the label. Aftermarket radios do not use Honda anti‑theft codes.
• No power to radio: Check relevant fuses in the cabin and under‑hood fuse boxes or consult a technician before attempting code retrieval.
• Security: Never post your full VIN and serial publicly. Avoid third‑party code sellers; Honda provides the code at no charge.

If you still can’t retrieve or enter the code, a Honda dealer can verify the unit and unlock it, and can diagnose any underlying power or wiring issues.

Summary

For a 2003 Honda Accord, look first for the 5‑digit anti‑theft code on a glovebox sticker or in the owner’s materials. If you can’t find it, get the 8‑digit radio serial via the 1+6 button method (or the nav diagnostic screen), then use Honda’s official lookup at owners.honda.com/service-maintenance/radio-navicode or contact a Honda dealer with your VIN and serial. Enter the 5‑digit code using the preset buttons; if locked out, leave the radio on for about an hour before retrying.
