How to unlock my 2002 car sterio
Hello! You will need to contact a GM dealership for the override code, but you will also need to provide them with some info from the radio. Follow these steps:
1) Press & hold the 2 & 3 buttons at the same time for about 10 seconds; a 2 or 3 digit code will appear, write this # down,
2) Press & hold the AM/FM button for about 10 seconds: another code will appear, write this # down as well.
You may also need to provide your VIN to the dealership as well.
Hope this helps and good luck! Thanks for using FixYa!
