Kia Optima: Description
The immobilizer system will disable the vehicle unless the proper ignition key is
used. In addition to the currently available anti-theft systems such as car alarms,
the immobilizer system aims to drastically reduce the rate of auto theft.

Encrypted SMARTRA type immobilizer
| A. |
The SMARTRA system consists
of a passive challenge - response (mutual authentication)transponder
located in the ignition key, an antenna coil, a encoded SMARTRA
unit, an indicator light and the PCM(ECM). |
| B. |
The SMARTRA communicates
to the PCM(ECM) (Engine Control Module) via a dedicated communications
line. Since the vehicle engine management system is able to control
engine mobilization, it is the most suitable unit to control the
SMARTRA. |
| C. |
When the key is inserted
in the ignition and turned to the ON position, the antenna coil
sends power to the transponder in the ignition key. The transponder
then sends a coded signal back through the SMARTRA unit to the PCM(ECM). |
| D. |
If the proper key has
been used, the PCM(ECM) will energize the fuel supply system. The
immobilizer indicator light in the cluster will simultaneously come
on for more than five seconds, indicating that the SMARTRA unit
has recognized the code sent by the transponder. |
| E. |
If the wrong key has
been used and the code was not received or recognized by the PCM(ECM)
the indicator light will continue blinking for about five seconds
until the ignition switch is turned OFF. |
| F. |
If it is necessary to
rewrite the PCM(ECM) to learn a new key, the dealer needs the customer's
vehicle, all its keys and the GDS equipped with an immobilizer program
card. Any key that is not learned during rewriting will no longer
start the engine. |
| G. |
The immobilizer system
can store up to eight key codes. |
| H. |
If the customer has lost
his key, and cannot start the engine, contact Kia motor service
station. |
