Audi A3 - Video tutorial

Model: Audi A3 MK 3, 8V - Years 2012-2019
Part: Key
Operation: How to replace the key battery of an Audi A3

Let's start by pressing the button on the top back of the key. By doing so we will be able to release the section of the key located at the top, which we will remove. Completed this step we will press and in the meantime we will extract the button that we discovered after removing the upper part. Once this is done, we will be able to extract the battery housing and the key battery itself. At this point, we will remove the exhausted battery (battery code in case you need it: CR2032), and install the new battery. At the end of this step, all we have to do is re-insert the battery seat in its previous position, and then insert the upper section later, and we will be finished.

How to reset the service in the Opel Antara?

As we can see in this tutorial, resetting the service in the Opel Antara is an extremely simple and fast operation. Before proceeding, of course, we must have completed all the planned maintenance work. We start by inserting the key but leaving it in the initial position, after which we keep the accelerator pedal fully depressed and at the same time turn on the instrument panel, not the engine. At this point, we release the accelerator and press it 3 consecutive times, always all the way. We then restart the panel to verify that the procedure has been carried out correctly.
