That used to happen to us all the time at Circuit City.  Contact a GM dealer with the VIN number of your vehicle, or even better, if you can remove the radio, get the serial number.  Ask for the parts department and they should be able to obtain the information for you. 

Note: some dealers actually charged us a research fee of $25.

This post and the procedures it describes might work for you, unless it's already been "locked out" by trying to unlock it too many times.
