I NEED A CODE FOR MY HONDA RIDGELINE 2006 RADIO, I JUST REPLACED MY CAR BATTERY, AS SUCH I DONT HAVE A CODE TO ENTER THE RADIO? VIN 2HJYK16556H004955 , RADIO SERIE 30002052

go to dealer with vin or vehicle and proof of ownership for code

need to notify dealer for code need vin and proof of id --also have vehicle scanned usually radio code needed when battery replaced or went dead but some people selling a used can with a bunch of check engine codes will clear them by disconnecting battery

Hold preset buttons #1 & #6 down, turn on radio. Keep holding down buttons, record 1st 4, then 2nd 4, of radio serial number. Either register your car on-line with Honda to get the code or go to a Honda dealer.

call dealership with radio serial number they should be able to help

turn radio off and hold 1 and 6 on the radio
turn radio on serial code will light up
call dealer with serial number and they will give you radio code

you can call honda if it is the factory radio.. if you give them the vin number they should be able to help you... once you receive it you should keep it saved somewhere because every time you disconnect the battery it will reset again... sometimes you can find the code in the owners manual or sometimes you get a little card with the code on it... good luck

I find my code in the glove box.

If the code is not written on the radio casing or inside the glove compartment (or similar place inside your car ) then the majority of HONDA codes are only available from here 

https://radio-navicode.honda.com 

You will require the car VIN number and Radio serial Number 

If they cannot provide your code then you will have to try your HONDA Main Dealer .....or a Decode Service who will plug in a laptop to read/recode the memory chip (EEPROM)

Options you have:

1 - Check your owners manual. Sometimes the code is written in there. It is a security code that locks the radio and renders it useless unless you enter the code to thwart thieves.

2 - Call Honda at 1-800-999-1009 and go to option #5.
The representative will ask you for your VIN # and some personal info like phone #, address and radio serial # (press 1, 6 and "on" button on your radio at the same time, record 10 digit code). They then proceeded to have you get in your car to try different codes.

3. You can got to this site https://radio-navicode.honda.com/ to enter the vin - but you will have to prove you own the car.

Hope this helps!

You will need to remove the radio from the das, and get the numbers off the back of it. Then you will need to call a honda dealership with your vin number and the numbers off the back of the radio. they will be able to get the code for it. The reason being, is for security, like if your radio was stolen a thief couldn't just reactivate it without the proper info.
Hope this helps!
