How to Unlock the Radio of an Opel Astra G

Model: Vauxhall Astra Astra G - Years 1998-2006
Part: Car stereo

In this video, you will learn how to enter the security code into the radio of the Opel Astra G after the battery has been disconnected or the radio has been replaced. When you turn on the radio, a message will prompt you for the code. The next step is to press and hold the "as" button for about two seconds. Once done, four dashed lines will appear on the display where you need to enter your code. Do this by pressing the first four buttons as many times as the numbers you need to enter, just as shown by the YouTuber in their example, until you see the code number on the screen. At this point, press and hold the "as" button for a few seconds, and the radio will be unlocked.
