2. IMMOBILIZER/REMOTE CONTROL KEY CODING
1) System Overview
While the communication between BCM/SKM and ECU is based on the CAN communication, the
communication between transponder and BCM/SKM is based on LF (Low frequency) and RF (Radio
frequency). When the ignition switch is turned to ON position, the BCM checks the verified transponder
according to the immobilizer verification procedure, if correct, allows the vehicle to start the engine. The
immobilizer indicator comes on during the communication and if the verification is carried out
successfully the indicator goes off.
If there is something wrong in the system, the indicator blinks.

3) Operation of Immobilizer
When the ignition switch is turned to the ON position with REKES key, the BCM checks the crypto code
of the inserted key using the immobilizer antenna and sends whether the engine is startable or not to the
engine ECU through the CAN communication so that the engine can be started.

1. SYSTEM LAYOUT
The vehicles with smart key system are equipped with the SKM (Smart Key Module) unit. The SKM,
which does not use the traditional key or remote controller to access the vehicle, provides 3 functions.
The passive UNLOCK function unlocks the door after confirming the smart key information and the
driver's door conditions when the driver carrying a smart key touches the door handle. The passive
START function starts the engine when the START switch is pressed by the driver sitting on the driver's
seat. The passive LOCK function locks the door when the door handle switch is pressed by the driver
after exiting the vehicle.
