SMART ACCESS SYSTEM WITH PUSH-BUTTON START DESCRIPTION
1. In addition to conventional mechanical key and wireless door lock control functions, the smart access system with push-button start enables door locking/unlocking, steering lock releasing, engine control system starting and back door opening without operating the key. The only requirement is that the key is in the possession of the user.
  - This system is controlled by the certification ECU (smart key ECU assembly). When the certification ECU (smart key ECU assembly) detects the presence of the key in one of the detection areas, it identifies and checks the ID code, and outputs operation signals to the related ECU in accordance with their functions.
  - The detection areas are formed by 4 oscillators and 4 antennas (4 door oscillators, the back door antenna and 3 indoor antennas).
