Anti Theft code w/ no serial number
I have a Honda Accord 2008 ELX w/ standard radio (no nav). Battery recently died and had to be recharged.
Since then, radio does not work. Prompt to enter the anti theft code which I have, but it doesn't work. I verified with the dealer and online tool that I have the right serial number and anti theft code.
Took it to the dealer. When we hold down 1, 6 and hit power button the serial number is supposed to be displayed, however, my car says "no S/N code".
Before we rip out the radio, anyone have any suggestions?
Appreciate any help. Trying to avoid a costly repair since this isn't under warranty any more.
