I had been following as many radio code threads as possible.
I have the card that came with my car but could not get it to accept it.
Then I realized that if I hit one more button it would beep, so I tried 11111. It beeped like it should, but that's not code, so I tried all the buttons like that 22222,33333,44444.
But when I hit 55555, no beep! The 5 does not always register!
So I kept hitting the 5 til it consistently beeped after 5 pushes.
Then I waited the hour, and pushed the code.
It worked, I have a working original radio!
Thank goodness.... I guess
