Question about 1999 Pontiac Grand Am GT
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.

It is part of the anti-theft system for the radio. As far as I know, the only way to stop it is to follow the instructions in the manual for unlocking it and enter the code you (or someone else) entered when you got the car. It usually happens when the radio loses power. That could be someone stealing it, or just disconnecting the battery for a little while. If you can't figure out the code, take it to the local dealer and they should be able to reset it.
