What is an Immobiliser and Should You Get One?

With vehicle theft nearly double what it was 10 years ago, car theft is a serious concern for vehicle owners in the UK. Modern technology has made cars more secure, but thieves have also upped their game.

One of the most effective tools to deter modern thieves is a car immobiliser. They add a solid layer of protection against theft, helping to keep your car secure. But what is a car immobiliser?

This blog covers everything you need to know about car immobilisers, covering what they are, how they work, and whether aftermarket immobilisers are worth the investment.

What is an Immobiliser?

An immobiliser is an electronic security device built into vehicles to help prevent theft. It ensures that only authorised users can start the car, adding an extra layer of protection. This feature is commonly found in modern vehicles and is highly effective in deterring car thieves.

How Does an Immobiliser Work?

A theft protection immobiliser system stops the car from starting if someone tries to start the car without the correct key or digital code. It does this by cutting off the fuel supply or disabling the ignition system.

Here’s how it works:

1. Transponder Key: Most car immobilisers use a transponder key system. The car key contains a small electronic chip (transponder) that communicates with the immobiliser system in the car. When you insert the key into the ignition or approach a push-button start, the car’s computer sends a signal to the key.
2. Verification: The transponder chip in the key sends back a unique code to the car’s immobiliser system. If this code matches the one stored in the car’s computer, the immobiliser allows the engine to start.
3. Preventing Theft: If the wrong key is used, or if someone tries to hotwire the car, the immobiliser cuts off the ignition or fuel supply, which prevents the car from starting.

Does Your Car Have an Immobiliser?

Immobilisers have become standard in many newer cars. They add a robust layer of security that significantly reduces the risk of car theft. However, not all vehicles come equipped with one, especially older models.

How To Check

Here’s how you can find out if your car has an immobiliser.

• Check the Vehicle Manual: Your owner’s manual should say if your vehicle has an immobiliser.
• Look for an Indicator Light: Many cars have an engine immobiliser light on the dashboard that blinks or lights up for a few seconds when you turn the ignition on.
• Ask the Manufacturer: Contact the car manufacturer or a dealership to confirm.
• Use an OBD Scanner: Some diagnostic tools can check the vehicle’s computer to see if an immobiliser is present.

Factory-fitted vs Aftermarket Immobilisers

You have two main options for immobilisers: factory-fitted or aftermarket.

• Factory-fitted Immobilisers: Installed by the car manufacturer during production, these are built into the vehicle’s electronics for seamless security.
• Aftermarket Immobilisers: Installed after the car leaves the factory, typically by a car security specialist. Aftermarket immobilisers, like the Ghost II Immobiliser, can offer extra features like remote immobilisation or advanced coding.

Benefits of Fitting an Immobiliser in Your Car

Fitting an immobiliser offers several significant benefits for vehicle owners. If your car doesn’t yet have an immobiliser fitted, it is a smart investment in your peace of mind. Here are the top reasons to fit an immobiliser in your car.

Protect Against Theft

The main advantage of an immobiliser is theft prevention. An immobiliser stops the car from starting without the correct key, making it much harder for thieves to steal your vehicle. Immobilisers are a strong deterrent to criminals who might otherwise rely on methods like hotwiring.

Lower Car Insurance Costs

Many insurance companies offer lower premiums for vehicles with immobilisers. Because the device reduces the risk of theft, insurers are often willing to provide discounts, which can lead to significant savings.

Are There Any Downsides to Installing an Immobiliser?

While immobilisers have many benefits, there are a few potential downsides:

• Installation Cost: Fitting an aftermarket immobiliser can be costly, especially for high-end systems. However, this is often offset by insurance savings and the added security.
• Possible Malfunctions: Like any electronic system, immobilisers can malfunction. If the immobiliser fails, it might prevent you from starting your own car, which could require an expensive repair.
• Compatibility Issues: Not all aftermarket immobilisers work with every vehicle model, so ensure that the system you choose is compatible with your car.

Who Should Install an Immobiliser?

A professional should install an immobiliser to ensure it integrates correctly with the car’s electronics. A qualified installer will have the skills and tools to fit the device without damaging the vehicle’s wiring or systems.

FAQs

Do all UK cars have immobilisers?

No, not all cars in the UK have immobilisers. While most vehicles made after 1998 likely have a factory-fitted immobiliser, older cars might not. It’s best to check your vehicle to be sure.

What is the difference between an alarm and an immobiliser?

An alarm is designed to alert the owner or passersby of a break-in or attempted theft with a loud siren. An immobiliser stops the car from starting without the correct key. While both provide security, an alarm is for deterrence and alerting, while an immobiliser prevents theft.

What triggers an immobiliser?

An immobiliser is triggered when someone tries to start the car without the correct key or fob. It can also activate if it detects tampering with the ignition system or an attempt to hotwire the car.

How do I know if my car has an immobiliser?

To find out if your car has an immobiliser, check the owner’s manual, or look for an indicator light on the dashboard. You can also consult with the car manufacturer or a professional installer, like Car Keys Solutions.

What happens when a car is immobilised?

When a car is immobilised, the engine won’t start. The immobiliser cuts off the fuel supply or disables the ignition, making the vehicle inoperable until the correct key or code is used.
