Radio Lock

[bigkevj]

Need an answer to a question.  I have a friend with a 02 Silverado, and when his battery dies, the radio locks and he has to go to a dealership to get it unlocked.  Will my 05 avalanche do this?  If so, does anyone know the sequence for the Silverado and/or for my Avalanche? 

Thanks for all your help.  I love this board!

Ask your friend if he previously entered in a code. My GM radio did the same thing when I left the vehicle for extended periods of time.

No, he has not entered the code.  The GM dealer here said they have to do it, and won't give it to him.  They have done it the last few times.
