Kia Optima DL3: Features of your vehicle / Smart key

Record your key number

The key code number is stamped on the bar code tag attached to the key set. Should you lose your keys, this number will enable an authorized Kia dealer to duplicate the keys easily. Remove the bar code tag and store it in a safe place. Also, record the code number and keep it in a safe and handy place, but not in the vehicle.

When you turn the ignition switch to the ON position, if the immobilizer indicator ( ) goes off after blinking 5 times, your transponder equipped in the ignition key is out of order.

To remove the mechanical key, press and hold the release button(1) and remove the mechanical key (2). To reinstall the mechanical key, put the key into the hole and push it until a click sound is heard.
