The KESSY electronic locking and starting system offers you convenient and secure access to your car. The system has two components: the transmitter and the starter module. You just carry the transmitter - the starter module is built into the dashboard. Within a radius of 1.5 metres around the car rolling codes are exchanged between the key and the car and the transmitter switches the system to 'Open' by the time you're behind the wheel the steering lock has been released and the electrical system activated. In the Passat you simply press the starter button to start the engine. One press on the buttons in the exterior door handles activates central locking. If the key has been left inside the car by mistake, the system will refuse to lock it.
