VAG Key login can easily extract security code (pin code), and also to be key programmer for vehicles from VAG, including WW, Audi, Seat, Skoda, Porsche Cayenne, Bentley Continental.
Above all, VAG key login immobilizer is rather cheap for you to try on your VAG vehicles, as am I. I got this device for almost one month. Here list my experience on how read pincode for my Audi A4 1.8T with VAG key login.
1.Plug the VAG key login into the OBD socket, and then it will power up. Also, you should turn on the ignition;
2.Loot at screen, it shows “Read PIN code”, and then press down to choose “key learning”;
3.And then select “key” or “keys” (according to how many keys you want to make, here take “keys”);
4.Next, you need to wait for a while until it pops out “Turn IGN OFF/ON”, and imply you to press a button. You just need to crank the ignition on and then off, and then press a button;
5.Waiting for 2 minutes or more, it pops out message reading “Learning Success”.
