Do Car immobilizer is helpful?


Importance of Car immobiliser: 

The car immobiliser is a secure electronic system that prevents the engine from starting without the presence of authorizing key. Hot-wiring is not helping at all to start the engine. The immobiliser is mostly in the form of the chip, which usually embedded in the car.


The installation of car immobilisers has compulsory to reduce the chances of theft since 1998. After that year every car has the immobiliser system. If you have a second-hand car and you didn’t find the order in it, then it might be the first owner who disables or remove it. Otherwise, there is no car made without it.



The manufacturer of the device is modifying it day by day. There are various functions are also introducing with the immobilisers. The system has a unique coded key which is allot to the owner. The vehicle security code is install in the key. When the key insert in the car, it activates the secure engine system. The engine only starts when the codes of key and engine immobilisers match.

Immobilisers working:

Every manufacturer design this system a little bit differently. But the motive of all the manufacturer is same that the vehicle engine is not going to start without the matching of key codes with engine immobilisers. There are three components after installing immobilisers that make your vehicle to move. They are name as ignition, fuel system, and motor starter. If two of these things disable the vehicle engine never start. The essential function of this device is not publish clearly to prevent the system from thieves.


Is all immobilisers are same?

There may be a difference in designs or models. The primary function of all mobilisers is same. One more variation can be a few of them are more secure and high rated and more expensive.

Types of Immobilisers:

There is a study in which the types of immobilisers introduce along with their theft reason which is highlight below:

  • Encrypted immobilisers Read-only immobilisers 
  • Radio remote immobilisers
  •  Ignition dependent immobilisers

Encrypted immobilisers: 

The immobiliser with the encrypted codes is highly secure and difficult to clone. In the year 2000, the cars along with system were more prone to theft. The fundamental reason behind is the key has the weak links with the car security; that’s why this security system defeat. The cars stole or even taken due to the excess of thieves on the system for some reason. This system sounds better in the case of opportunistic thieves as they are lazy of their kind interested in accessible opportunities. The professional technical thieves are still not understood.

Read-only immobilisers:

This is a sound immobiliser system, but the defect is read-only transponder system is more easy to cloning. The conclusions of this system are almost the same as an encrypted system. The hackers and professional, intelligent thieves has the strategies to break in and steal the car. But something is better than nothing; hence the surety of immobilisers is compulsory. At least it save us from small mind thieves.

 Radio remote immobiliser:

It has the potential security, the cars in which this system is install never report to get theft. There is no doubt that this system has no significant weakness in production. The vehicles which were stole with this system reports that immobiliser not working on that time. In one case the keys stole that’s why the car theft.

Ignition dependent immobilisers: 

In this system, the immobiliser got deactivate system by inserting key in the ignition. The theft cases are not much complicated. Either the keys are stole, or the owner left keys in the ignition. We can’t blame thieves for that.

By the conclusion of the study, it is prove that the cars which have to install the immobilisers are being safe from stole. However, the group of professional hacker thieves are negatively using their mind and manage to steal the cars. Target cars are Ferrari and BMW mostly. So the immobiliser is useful in the security of your vehicles.
