I need a security code

is there a reset code or way to reset the security code for a used kenwood kdc x579?

I am having the same problem I have tried almost 5000 different coders and have had no luck. Can you let e know if you hear anything ? Thanks Kent @ kent_kegley@yahoo.com

I bought my truck with the CD Player already in it and I don't have my Manual for the player. It worked for a long time but here recently I had to change my alternator and when I got my truck back the CD feature on the player didn't work. I noticed that there are tw bars that have my CD locked in it. The radio still works but it won't play the CD of eject it. I figured it was a security feature that happed when the battery was unhooked. ANy help would be appreciated. Thanks.
