Immobilizer system
Your vehicle may be equipped with an electronic engine immobilizer system to reduce the risk of unauthorized vehicle use.
Your immobilizer system is comprised of a small transponder in the smart key and electronic devices inside the vehicle.
With the immobilizer system, whenever the ENGINE START/STOP button is changed to the ON position, it checks and determines and verifies if the smart key is valid or not.
If the key is determined to be valid, the engine will start.
If the key is determined to be invalid, the engine will not start.
To activate the immobilizer system:
Change the ENGINE START/STOP button to the OFF position.The immobilizer system activates automatically. Without a valid smart key for your vehicle, the engine will not start.
To deactivate the immobilizer system:
Change the ENGINE START/STOP button to the ON position.

In order to prevent theft of your vehicle, do not leave spare keys anywhere in your vehicle. Your immobilizer password is a customer unique password and should be kept confidential. Do not leave this number anywhere in your vehicle.

When starting the engine, do not use the key with other immobilizer keys around. Otherwise the engine may not start or may stop soon after it starts. Keep each key separately in order to avoid a starting malfunction.

Do not put metal accessories near the smart key. Metal accessories may interrupt the transponder signal and may prevent the engine from being started.

If you need additional keys or lose your keys, Kia recommends to visit an authorized Kia dealer/service partner.
