Question
the stereo in my  99 pontiac grand am is locked and says i need to enter a code but i do not know the could i could really use some info on what i need to do

Answer
Try this,
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 go to your car dealer  about $70.00 charge or call 1-888-231-0395 charge is about $20.00 to 25.00  they  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 code

this is the same for any DELCO LOC any gm radio from 1995 to 2002 can use this instructions
good luck
