How to open the Audi A4 key and replace the outer shell

Model: Audi A4 B8 - Years 2007-2016
Part: Key

To open the Audi A4 key and possibly change the external protective shell, you must first remove the internal key by pressing the button on the chromed side of the key, once the key has been extracted always with the same button we used to extract the key, we extract the battery housing with the battery itself, now inside the remote control we find the electronic card with the immobilizer and the buttons for opening, closing the car and opening the tailgate. With the help of a small pliers we grab a tab where the battery is housed, slowly slide out and the electronic card comes off with the immobilizer inside. Now we can take the new protective shell, insert the card until we hear a click, reinsert the battery compartment with the battery and the key. At this point we can verify the correct functioning of the remote control.
