Hey there. This is a basic question, but I thought maybe some of you audiophiles would have ideas. My SVT had a Kenwood KDC-8009 cd player in it when I bought it, which is now asking for a security code I don't have after I had the battery and alternator replaced. Does anyone know of a way to make it work again that doesn't involve paying an "authorized Kenwood dealer" $45 to spend 5 minutes plugging a special code in with their remote?

I can't contact the former owner who probably set the code. Thanks in advance...
