How do I find the radio security code for a 2003 Holden Astra?
Answered by CarsGuide
30 Aug 2024The first thing to do is find the owner’s manual and any paperwork that came with the car when it was brand new. Many dealerships wrote the security code on a business card that was slipped into the owner’s folder, others sometimes write the code somewhere on one of the manual’s pages. Either of which kind of defeats the purpose of a secret code, but it was common practice.
If that doesn’t pay off, you may have to remove the radio from the dashboard, record the unit’s serial number and contact either Holden or the stereo’s manufacturer (I think Blaupunkt, in this case) to see if it has records of what security code went with what radio.
Finally, there’s another long-shot that might pay off. Your car has an individual VIN (Vehicle Identification Number) which should be recorded on a metal plate at the edge of the windscreen, under the glass. The last four digits of this VIN are often the security code for the radio fitted at the factory. It doesn’t work on every make and model, but it’s free and worth a shot.
