(1) Passive entry actuation area

Searching for a smart key signal from the outside the vehicle is prioritized in the theft deterrent mode 

when the passive entry signal is input. Searching for a smart key signal from the inside is prioritized 

when the theft deterrent mode is deactivated.

The system searches a smart key only in the actuation area of a switch, which the signal is input 

(driver/passenger door handle switches and tailgate open switch).

The passive entry actuation area refers to the area where passive LOCK/UNLOCK can be 

performed by pressing the switch on the driver or passenger door handle with a smart key carried by 

the driver.

The passive tailgate open actuation area refers to the area where the tailgate can be opened by 

pressing the tailgate switch with a smart key carried by the driver.

The smart key verification many not possible in an area where the communication is poor, such as 

the seat cushion that the seat heated wire is operated, around the pedals and the on the floor.

The smart key system malfunctions may occur when generating radio waves around the smart key 

or vehicle, or attaching a electronic device which generates radio waves on the smart key or 

vehicle.

(3) Passive LOCK

The passive LOCK (door LOCK) is activated by the door handle switch with a valid smart key present 

within the passive entry actuation area.

Passive LOCK and verification by door handle switch

▶

The ignition is turned OFF or ACC is turned ON.

All doors are closed and the driver door is unlocked. 

The door handle switch on the driver or passenger door is pressed briefly. 

The SKM verifies if a smart key is outside the vehicle using the door handle antenna (LF verification) 

(The SKM searches the last smart key used first. Searching for a smart key signal from the outside 

the vehicle is followed by searching from the inside the vehicle).

The verification signal (RF verification) from the smart key is sent to the REKES antenna of the SKM.

The SKM sends the Passive LOCK signal to the BCM through the B-CAN if the verified smart key is 

found outside the vehicle.

The BCM receives the signal from the SKM and controls the door LOCK actuator and turn signal 

lamp. (The buzzer sounds once and hazard warning lamp flashes twice when the system enters the 

theft deterrent mode)

If no smart key is identified as being outside the vehicle, the passive LOCK process is stopped and 

restarted when the next signal is received from the door handle switch.

When the door handle switch is pressed with ACC ON and driver door unlocked, the SKM changes 

the ignition status to OFF and sends the passive LOCK signal to the BCM through the B-CAN to lock 

the door. The BCM ignores the signal if the ignition is turned ON.
