How does the SEAT Leon Kessy function work? | SEAT

Our keyless locking and start system helps you to unlock and lock your SEAT without actively using the key or the control. You only need to carry the key but not hold it in your hand, which is very convenient.

How does the SEAT Leon Kessy system work? SEAT's car detects the key less than 2 meters away, and you can open the door and unlock your vehicle just by touching the sensor inside the door handle or touching the outside sensor if you want to lock your car.
