Trying to reset stereo on 2007 Honda Fit after replacing battery. I have 2 security codes. The 1st didn't work, the 2nd code's 1st number is a 7. My stereo only has numbers 1-6. Are there other buttons that represent 7,8,9, and 0?
Are you sure that it is in fact the security code? What you could have is the stereo's serial number. They are often listed in 2 blocks because that's how they are displayed on a car's information screen. There's no such thing as "2 security codes" for a car stereo.
Try retrieving the security code from this site using either your VIN or the stereo's serial number (those 2 blocks of numbers you have, string them together).
