Most vehicles manufactured in the last 20 years come equipped with a car immobilizer system as a standard anti-theft feature.

It significantly reduces the chances of your automobile getting stolen when it operates correctly.

But, how does an engine immobilizer function? And how can you determine if your car is equipped with an immobilizer?


What Is A Car Immobilizer?


A car immobilizer system, also referred to as an engine immobilizer, constitutes an electronic security technology designed to discourage and prevent vehicle theft.

Its primary objective is to thwart unauthorized attempts to start a car without the corresponding key, thus deterring theft.

UK Government statistics indicate a significant decline in vehicle theft cases since 1992, coinciding with the widespread adoption of immobilizers as a standard feature.

If you have purchased a car within the last two decades, likely, you have already used this technology unknowingly.

Car dealerships are increasingly providing key fobs or smart car keys instead of traditional keys.

These modern keys often feature buttons on their base for functions such as locking and unlocking car doors, opening the trunk, and, in some instances, remotely starting the vehicle.

Moreover, many newer vehicles incorporate a feature called keyless entry, enabling access to the vehicle without the need to press any buttons.

In cases where the vehicle is equipped with another feature known as “keyless go,” you can also start the vehicle while retaining the key in your pocket.

Modern car keys serve as an additional security component beyond initiating your car’s ignition.

Key fobs and smart keys contain a transponder chip.

When you start the engine or have the key fob inside the vehicle it establishes communication with the car’s immobilizer technology.

If the pin code transmitted by the key fob matches the one stored in the immobilizer system, the vehicle will activate.

Otherwise, it will remain inactive.

In the event of someone attempting to turn the ignition using a counterfeit key with an incorrect code, most immobilizers trigger an alarm.

Additionally, certain digital automotive systems can notify a security service.

The security service or accompanying app will contact the user to verify their absence from the vehicle and then report the attempted theft.

Some companies have enhanced their immobilizers to employ a two-tier security system comprising fixed and changeable codes.

The permanent code is initially checked by the immobilizer when you attempt to start the car.

It is then followed by a request for the second, variable code.

This code is compared to the one stored in the database before the car is allowed to start.

Upon successfully starting the vehicle, the immobilizer generates a fresh second code and transmits it to the transponder.

This ongoing process ensures the dynamic nature of the security system.

This is because the car will not start without the correct second code.

How To Check If Your Car Has An Immobilizer


Several indicators can help you determine if your car is equipped with an immobilizer or not.

Your primary source of information is your car’s handbook.

It should contain comprehensive details about your vehicle, including whether the manufacturer installed an immobilizer.

Two other clues are your car’s make and the type of key it uses.

If your car’s make is from 1998 onwards, it is highly likely to feature an immobilizer.

Additionally, the presence of a key fob or smart key almost certainly indicates the presence of an immobilizer.

Assuming you purchased the car new and no one has tampered with the immobilizer system.

However, if you acquired your car as a used vehicle, there is a possibility that a previous owner disabled or removed the immobilizer.

Conversely, even if your car did not originally come with an immobilizer from the factory, a previous owner might have added one.

Your car’s handbook should contain information regarding the immobilizer, including any modifications or removals.

If this information is not readily available, a competent mechanic should be able to inspect the vehicle and provide you with the necessary information.



Frequently Asked Questions


Can You Remove An Immobiliser?


When considering the removal of a Ghost Immobiliser, we strongly advise against attempting to do it yourself.

Unless you are the one who initially installed it or have prior experience with successful removal.

This caution is due to the system’s direct impact on your engine.

Any mishandling during removal could potentially lead to engine damage.


What Activates The Immobilizer?


Upon insertion, the immobilizer processes the security code from the smart key’s chip and matches it with the code embedded in the vehicle’s ECU.

When a perfect match is confirmed, the engine immobilizer activates both the fuel system and the ignition circuit.




In conclusion, determining if your Kia has an immobilizer is crucial for understanding your vehicle’s security features.

Most modern cars, including Kia models from 2022, come standard with immobilizers.

This significantly reduces the risk of theft when functioning correctly.

To verify if your Kia has an immobilizer, consult your car’s handbook for manufacturer-provided information.

Additionally, consider your car’s make and the type of key it uses as indicators, with key fobs or smart keys often indicating the presence of an immobilizer.

If you bought a used car, it’s wise to check for any modifications or removals related to the immobilizer.

Remember that tampering with immobilizers can damage your engine, so seek professional assistance if needed.
