VW Passat B6 smart keys have two types: smart key and semi-smart key. Smart key is equipped with 46 chip, semi-smart key is 48 chip. Smart key is you can start the car when the key in your pocket. Semi-smart key requires you insert the key to key slot when you start the car. We need to know what chip the key use before programming the key. If all key lost, we can check the push-start button, if there is a key mode in the button, the key is ID46 chip, if not have, it is ID48 chip.


The programming method is same because Magotan and CC are same type car. Below are programming details:
