up, How do i unlock it? I have a 2002 Chevy Impala I took out the battery out to change it and now the stereo locked up. the stereo doesn't even turn on now. How do i unlock it?
The stereo has a code you have to enter the code comes on the radio new. You may have to call a dealer and get them to tell it to you though there was at one time a site on the net that would do it for free.
