The first method is to contact Holden with you car details, this will cost you money. If you have the original owners manual it is often listed in there. If you don't, you will need the serial number for the system fitted. This usually involves taking the stereo out of the dashboard as the serial number is printed on the side of it.
Try some of the Holden Astra owners forums as they might give you the code. Some unlock codes are specific to the stereo and not the car.
If you have the serial number there are some websites where you can get the code for free.

Hi Jenny You need to go to Holden's for this code. They may have to remove the radio for information so there might be a charge, enquire on booking. Search through all your paper work first including purchase invoice and hand book in case someone has made a note of it. There are hundreds if not thousands of numbers used . Good luck

Ask your question again. But you will need the serial number off the stereo. Try listing the make and model of the stereo too, to direct it to an expert equipped to answer your question.

This may help:

All code are different ,your dealer can find it for you .will cost you . will need id of owner ship.
