Why Does My Honda Accord Radio Ask for a Code?
Honda Accord radios use an anti-theft security system. When the radio loses power, it can lock itself and ask for a security code before it works again.
This usually happens after replacing the battery, disconnecting the battery, fixing electrical problems, or buying a used Accord where the radio code was not provided.
Good to know: The radio is usually not broken. It simply needs the correct Honda Accord radio code.
Where to Find Your Honda Accord Radio Code
Check the Owner’s Manual Pack
The easiest place to check is the original Honda document folder. Many Accord models came with a small anti-theft radio code card inside the owner’s manual pack.
- Open the Honda Accord owner’s manual folder.
- Look for a small card marked Radio Code or Anti-Theft Code.
- Write down the 4 or 5 digit code exactly as shown.

Check the Glove Box
Some Honda Accord owners find the radio code on a sticker inside the glove compartment. Check the side wall, inside panel, and back area of the glove box.
Check Previous Service Records
If the car was serviced before, the code may have been written on an invoice, service note, or old document from a Honda dealer.
How to Find the Honda Accord Radio Serial Number
If you cannot find the code card, you will usually need the radio serial number. On many Honda Accord models, you can display the serial number without removing the radio.
- Turn the ignition to ON, but do not start the engine.
- Turn the radio off.
- Press and hold preset buttons 1 and 6 together.
- While holding 1 and 6, press the power button.
- The display may show serial details, often starting with U, L, or similar characters.
- Write the serial number down carefully.
If nothing appears, the serial number may be printed on the radio label. In that case, the radio may need to be removed from the dashboard.
