I'm really hoping someone can help me. My husband disconnected my moms battery in her car and now the radio is asking for a four digit unlock code. She called the GM dealership and they want $100 for the code. I was wondering if anyone knew the code of a way to get the code for free? Thanks so much!

I meant to say or another way to unlock the radio!

Here are the codes to unlock your radio. You enter them using the radio preset buttons. Trial and error...

Thank you, thank you! I had same problem - one of the above numbers worked! I love you!

How can I do if my car shows six spaces to put six different numbers... some one can help me?

I'm looking for the code, but the list is just four numbers and my cars says that must be six.. so... anyone know about it

Hi! Thank you norden porsche. I tried one of the code and it works also for my car as well. Thanks a lot!

I certainly hope that when you found the correct code that unlocked the radio, you wrote it down in you owner's manual. Duh!
