This may be a little late. But I can answer the problem for you. The only way to ge the code, unless you find the code identification car that comes with the car, is to get the serial number off the oem radio. The only way to do this is to remove the radio. I can tell you how to do that too if you wish. The dealership can only retrieve the code from the serial number. Not the VIN number or anyhting else. If you need more help, just contact me.
