I have the full Kessy kit on my Tiguan, which came as an extra on a cancelled order, and I am really glad that it was already on the car, as without the experience of living with it, I may not have ordered it, especially at £600 plus, but that would have been a mistake, as it is worth every last penny.
Sometimes I am loaded up and the boot is open, with the keys buried deep in my pocket or a carrier bag etc, so I gently push one of the close buttons with my walking stick and it all works a treat?
