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.

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.
