SMART KEY SYSTEM DESCRIPTION
1. In addition to conventional mechanical key and wireless door lock control functions, the smart key system enables door locking/unlocking and hybrid control system starting without operating the key. The only requirement is that the key is in the user's possession.
  - 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 smart key system 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 6 oscillators (2 door oscillators, 1 outside oscillator and 3 indoor oscillators).
