What is Engine Immobiliser in a Car?
Introduction
An engine immobiliser is an electronic security device that prevents a vehicle from being started without the correct key or authorisation. It is a vital component of modern vehicle security systems and plays a crucial role in deterring theft.
How Does an Engine Immobiliser Work?
An engine immobiliser operates by using a computer chip embedded in the vehicle’s key or key fob. When the key is inserted into the ignition, the chip communicates with the immobiliser system in the car. If the chip matches the code stored in the system, the immobiliser disarms, allowing the engine to start.
If the key or chip does not match the code, the immobiliser remains active, preventing the engine from starting. This makes it extremely difficult for thieves to hotwire or start the vehicle without the correct key.
Types of Engine Immobilisers
There are two main types of engine immobilisers:
- Passive immobilisers: These immobilisers operate automatically when the key is removed from the ignition. They require no additional action from the driver.
- Active immobilisers: These immobilisers require the driver to activate them manually, usually by pressing a button or entering a code. They provide additional security but are less convenient than passive immobilisers.
Benefits of Engine Immobilisers
Engine immobilisers offer several benefits, including:
- Theft deterrence: Immobilisers make it extremely difficult for thieves to steal vehicles by preventing them from starting the engine.
- Insurance discounts: Many insurance companies offer discounts on premiums for vehicles equipped with immobilisers.
- Peace of mind: Immobilisers provide drivers with peace of mind, knowing that their vehicles are protected from theft.
Installation and Maintenance
Engine immobilisers are typically installed during vehicle production. However, they can also be retrofitted to older vehicles by a qualified technician.
Immobilisers require minimal maintenance. However, it is important to replace the batteries in electronic key fobs regularly to ensure they continue to function properly.
Conclusion
Engine immobilisers are essential security devices that play a vital role in deterring vehicle theft. They operate by using a computer chip to prevent the engine from starting without the correct key or authorisation. Benefits of immobilisers include theft deterrence, insurance discounts, and peace of mind.
If you are considering purchasing a new or used vehicle, ensure it is equipped with an immobiliser system. This simple measure can significantly reduce the risk of your vehicle being stolen.
