Passive Entry and Push Start


        Passive Entry and Push Start (PEPS) system is an intelligent electronic system that provides more convenient and safer access to the vehicle. Using the RFID (Radio frequency identification) techonology, The system of traditional mechanical and wireless keys are replaced by the “passive key” (or smart key) which allows the driver to unlock the car without touching the key and the engine can be started and stopped with a push of the ignition button.
