    There was a request in the tagbox for help in unlocking their radio, I found this post on another forum and thought it might help them and all of us just in case.

    Try this, it worked for my 1998 Sunfire and a 1975 Monte Carlo.
    Press & hold the 2 & 3 buttons @ the same time for about 10 seconds; a 2 or 3 digit code will appear, write this # down,press & hold the am/fm button for about 10 seconds: another code will appear, write this # down, then call 1-800-537-5140 and enter 202108 followed by the # key, then enter the #'s that you wrote down from your radio followed by the * key. The call will give you a 3 or 4 digit override code. Write this code # down so you have it if you ever need it again. Enter this # into your radio following the instructions in your owners manual. If you get an override code that starts with 0, you drop the 0 when entering the code into your radio.
    If you don't have an owners manual, try this, press & hold the hour button until the first 2 digits of your code come up, then press & hold the minute button until the last 2 digits show. Then press the am/fm button. This should reset your stereo. It did mine.
    Hope you find this helpful.

    Where do they come up with idea of how these things should be set up. It's almost as difficult as programming your remote.

    Thanks for the info.
