• preset buttons 1 and 6 together
• on some radios, 1, 6 and Power together

The serial shows either as a U number and an L number (for example U2154 L2135) or as a single S/N number (for example S/N 2602353). Enter whichever format appears on your screen.

• Power + Menu + Day/Night (about three seconds)

Then touch Detail Information & Setting → Unit Check → HMI Unit or DA Unit to see your serial. Tap Return to exit.

What your serial looks like
These are real Honda serials, on radio labels and on screen, so you can see exactly what to look for.

Serial not showing on your screen? Remove the unit with DIN release keys or a flathead screwdriver and slide it forward. The serial is on a sticker on the top, side or rear of the casing, usually 6 to 14 characters (for example 954LR052 or SN500074). Enter it exactly as printed.

FAQ

Frequently asked questions

Can I Bypass The Radio Code?
Unfortunately, the radio code cannot be bypassed without entering the correct code into the radio. We have made getting your code as easy as possible.
How Do I Remove A Honda Radio?
Most Honda radios never need to come out. With the radio on, hold preset buttons 1 and 6, on some units 1, 6 and Power, for a couple of seconds and the serial appears on screen. Only if nothing displays do you need to slide the unit out, and the guide above shows both routes step by step.
How Do You Reset A Honda Radio Code?
You cannot change or reset a Honda radio code. It is set at the factory when the radio is built and stays the same for the life of the unit. That works in your favour, once you have your code it will unlock the radio every time it asks.
Why Do I Need A Radio Code?
A radio code is anti-theft code, which has largely reduced the theft of radios from cars. We get the radio codes from a secure database which flags any reported stolen radios.
How To Get Radio Code For Honda?
At OnlineRadioCodes, we have made it as easy as possible to get your radio code online in minutes, simply fill in your cars serial number and we send the code.
How To Unlock Honda Radio Without Code?
Unfortunately, Honda radio codes can not be bypassed, the only way to unlock the unit is to input the correct original pre-set code.
My Radio Is Displaying "ERR"?
ERR means the last code entered was wrong. Switch the radio off and on and try again slowly, checking each digit. After around ten wrong attempts the radio locks temporarily. If that happens, leave it powered on for about an hour and it will accept the code again. No dealer visit needed.
