Are Ghost Immobilisers Worth It

The best way to get a Ghost immobiliser installed

Ghost Immobilisers are one of many aftermarket security modifications you can opt for. Ghost Immobilisers have proven to be a valuable option especially for those who own luxury vehicles, or vehicles that are prone to theft.

In this blog, we will answer the question ‘Are Ghost Immobilisers worth it?’

The UK automotive aftermarket industry is thriving, ranking fourth in Europe and ninth in the world in terms of size, and turning over an annual £21.1 billion.

The sector supports 345,600 jobs and contributes £12.2 billion each year to the economy. And it is growing: the sector’s value is set to rise to £28 billion by 2022.

That’s why we at Car Specialist Customs are here to provide you with all the information you require to get the best car customisation possible, whilst being as informed as possible.

How does a Ghost Immobiliser stop a car from starting?

A Ghost immobiliser itself doesn’t directly stop any physical parts of the car from working. Instead, it disrupts the car’s electronic communication system in a way that prevents the engine from starting. Here’s how it works:

  • Target: The CAN Bus: Unlike traditional immobilisers that target specific circuits, Ghost systems focus on the Controller Area Network (CAN Bus). Think of the CAN Bus as the car’s central nervous system, carrying digital messages between various electronic components like the engine control unit (ECU), instrument cluster, and sensors.
  • Communication Blockade: The Ghost immobiliser essentially acts like a silent blocker within the CAN Bus. It intercepts or disrupts the critical communication between the ECU and other components needed for engine starting. Without receiving the necessary signals and authorization, the ECU won’t allow the engine to turn over,effectively immobilizing the car.
  • Unique PIN for Unblocking: To “disarm” the immobiliser and restore normal communication within the CAN Bus, you (the driver) need to enter a pre-programmed PIN code. This code is secretly entered using a series of button presses on existing car controls, making it a non-obvious sequence for thieves to guess.

Essentially, the Ghost immobiliser works like an invisible shield within the car’s electronic network. It creates a roadblock that prevents the engine from receiving the green light to start, and only the authorized PIN code can remove this blockade.

Here’s an analogy: Imagine a car needing three keys to start: a physical key, a hidden switch, and a specific password. The Ghost immobiliser acts like the hidden switch and password, adding an extra layer of security that prevents unauthorized engine start-up even if someone has a physical key.

Which vehicles can’t have a Ghost Immobiliser?

There are very few vehicles that categorically cannot be fitted with a Ghost Immobiliser. The system is designed to be compatible with a wide range of cars, but there are a couple of exceptions:

  • Vehicles Exempt from MOT Tests: These include tractors, some agricultural machinery, and some very old vehicles. Since they don’t have a standard registration system and may not have a modern CAN Bus system, a Ghost Immobiliser wouldn’t be applicable.
  • Vehicles with Q Registrations: The DVLA issues Q registrations for vehicles with doubtful identity or age. These vehicles typically require further investigation before being eligible for a standard registration. Until the situation is resolved and a standard registration is obtained, fitting a Ghost Immobiliser wouldn’t be possible. However, there’s a chance you can get permission.

If you have evidence to prove the vehicle’s age (especially for kit cars), you can apply to the DVSA for permission to use window tint, which uses a similar logic to Ghost Immobiliser installations. This might also apply to getting permission for a Ghost Immobiliser.

Can a thief reset your Ghost Immobiliser?

Whether a Ghost immobiliser is worth it depends on several factors, including your car’s value, theft risk in your area, and your budget. Here’s a breakdown to help you decide:


  • Strong Deterrent: Ghost immobilisers are highly secure and make it very difficult for thieves, especially casual ones, to steal your car.
  • Covert Installation: The hidden nature of the system makes it challenging for thieves to locate and tamper with.
  • No Detectable Signals: Unlike traditional immobilisers, there are no radio frequencies to scan for, further increasing its stealth.
  • Unique PIN Code: Entering a PIN using existing car controls eliminates the risk of losing a separate key fob.
  • Emergency Override: A recovery procedure exists if you forget your PIN.


  • Cost: Ghost immobilisers are generally more expensive than traditional immobilisers.
  • Not Foolproof: Highly skilled thieves with advanced tools might exploit vulnerabilities in the car’s CAN Bus system, although this is rare.
  • Social Engineering Risk: If someone observes you entering your PIN, they could steal your car.
  • Potential Insurance Discounts: While not guaranteed, some insurers might offer slight discounts for vehicles with additional security measures like Ghost immobilisers. It’s best to check with your insurance provider directly.
