Hi, I bought a 2007 Honda Ridgeline The radio

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.

Take it to your local Honda Dealership. The radio will have to be removed and sent out to be repaired.

call dealer with VIN number and radio model from service manual or data plate

That would be at a dealer,with your VIN # & proof
of ownership

The code is so only you can use the radio & only
in one vehicle,yours,if stolen, it won't work anywhere
else.

Why are you giving out your VIN# ,next you will
be giving us your credit card or social security number,stop

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

You need the code for the radio right? If so push and hold the 1 and 6 and push the power button. you will have two sets of numbers come up on the screen write these down and call your dealer. Give them the numbers and tell them you need a radio code. Then input the numbers in the radio and push the fm button.

contact your local honda dealer and they should be able to help you obtain the code or the original dealer that sold the vehicle. you will also need your vin and proof of ownership

Hi,
I bought a 2007 Honda Ridgeline. The radio is locked. Kindly help me with the code. These numbers are on the radio which is a 6 CD loader which i think is pioneer.

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)

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!
