(6) Limitations/Interruption of smart key function

The SKM searches for a smart key inside the vehicle when it receives the information on entering the 

theft deterrent mode from the BCM. If a normal smart key is identified, the SKM memorizes this as a 

function-limited key (Silent Smart Key) or a function interrupted key (Deactivation Smart Key) according 

to the conditions.

If a smart key, which outputs the door LOCK signal, is found inside the vehicle, the SKM memorizes 

all the smart keys inside the vehicle as function limited keys (Silent Smart Key).

The function limited smart key provides the passive START, ignition status change and REKES 

functions except the passive UNLOCK function.

ignition status change and REKES functions.

4) Smart Key Verification Time Control

(1) Pre-verification timer

When the operation signal from the START switch is received, the START & power control functions can 

be performed without smart key verification. 

(2) Immobilizer verification timer

The immobilizer verification status indicates that it is possible to respond to the request message sent 

from the EMS to deactivate the immobilizer. The SKM verified a smart key and the engine can be 

started.

The 30-second immobilizer verification time is started when:

the ignition status is changed to IGN by the START switch while the pre-verification timer is activated.

the ignition status is changed to IGN by the smart key verification while the pre-verification timer is 

stopped; the SKM verified a smart key by the brake switch signal while the immobilizer verification 

timer is stopped or the ignition status is IGN ON.

the SKM verified a smart key successfully if the immobilizer verification timer is stopped with IGN 

ON/immobilizer verification /brake switch ON.

Condition

SKM operation

- when door closed signal is input with - B+ or ACC ON
- when brake is applied with - B+ or ACC ON
- when START switch is operated with - B+
- when smart key is inserted into slot & brake switch is 
  operated or START switch is operated with - B+

Once the vehicle interior verification 
is completed, 30 sec. pre-verification 
timer is started

when the ignition is turned OFF with IGN ON and engine 
running 

30 sec. pre-verification timer is 
started without re-verification 

Timer deactivation conditions: after 30 sec. has passed, IGN ON, Outside door handle switch ON, 
entering theft deterrent mode when door condition is changed

IGN1 OFF

30 sec. has passed after immobilizer verification

Any door is opened and then closed when all doors are closed & smart key out

When the engine starts to run, the immobilizer verification status is determined, and the immobilizer will 

not be deactivated until the ignition status is changed to IGN/ACC/OFF.

The immobilizer is not deactivated when the key out warning condition is met while the engine is 

running. (when the RND is received by the EMS reset while the engine is running)

When attempting to start the engine without immobilizer verification, the system performs smart key 

verification procedures, and sends the engine start request to EMS only when the verification result is 

normal.
