Passive Start and Entry (PASE)

With the Passive Start and Entry (PASE) solution it is possible to access the vehicle and start the engine without having to hold the key in your hand. The vehicle’s system recognizes the matching PASE key automatically on approach, automatically starts systems, adjusts customized settings, and opens the vehicle – for the driver, this means maximum ease of use as well as maximum convenience: simply get in and drive off. Continental’s PASE system, first introduced in 1998, is undergoing continuous development.

The system typically consist of a central ECU with integrated or external RF antenna, a start-stop button, several LF antennas plus the key FOB.


  • Maximum convenience for the driver
  • Lower system costs thanks to optimization of the components used (antennas and sensors)
  • Different antenna designs depending on the vehicle segment and market
  • Personalization based on unique ID
  • Secure transmission of data via ISM frequencies licensed for worldwide use
  • Shared use of HF receiver of the tire pressure monitoring system
  • Simple mechanical application thanks to small and flexible LF antennas
  • Integration of PASE technology into fashionable wearables, to be used as additional vehicle key
  • Maximum convenience when combined with Smart Autonomous Door technology and our Power Liftgate controls


  • Lock, unlock using the key FOB buttons (RKE)
  • Passive Entry and Start without the use of the key
  • Welcome Light: automatic car illumination when approaching the vehicle
  • Approach Unlock: automatic door unlock when approaching car
  • Walk Away Locking: automatic door lock when leaving the car
