ToggleGhost Immobiliser explained
A Ghost Immobiliser is a high-tech vehicle security system that works by preventing a stolen vehicle from being driven, even if the thief has the car keys.
Unlike traditional security measures that can be bypassed with a little technical know-how, or even brute force, the Ghost Immobiliser uses a complex algorithm that’s almost impossible for thieves to crack.
What makes a Ghost Immobiliser one of the most effective security systems?
Ghost Immobilisers offer the benefit of completely preventing the vehicle it is installed on from moving unless the correct PIN code is entered, even if the thief has the car keys.
In addition to the fact that it is hidden when installed, and has complex algorithms that ensure it is extremely difficult to hack, the Ghost Immobiliser is far above traditional security devices and systems for vehicles.
Is a ghost immobiliser the only aftermarket security for a car?
While Ghost Immobilisers are a popular choice, there are other effective aftermarket car security systems available:
Electronic Immobilisers
- Engine Immobilisers: These prevent the engine from starting without a valid key or code.
- Steering Wheel Locks: These physically prevent the steering wheel from turning, making it difficult to drive the vehicle.
- Gear-lock Immobilisers: These lock the gearbox in neutral, preventing the vehicle from moving.
Alarms and Tracking Devices
- Audible Alarms: These loud alarms can deter thieves and alert neighbours to a potential break-in.
- Silent Alarms: These alarms send a signal to a remote location, allowing you to be notified of a potential theft.
- GPS Tracking Devices: These devices can help locate a stolen vehicle if it is recovered.
Additional Security Measures
- Steering Wheel Covers: These can make it more difficult for thieves to steal the car.
- Window Etchings: Etching your VIN number on your windows can help identify the vehicle if it is stolen.
- Hidden Kill Switches: These switches can be installed in a hidden location, allowing you to disable the vehicle remotely.
What makes Ghost Immobilisers so hard to detect?

Ghost Immobilisers, aside from their incredible level of security, are renowned for the fact that they can’t normally be found by thieves in order to disable. This includes physically and in terms of hacking the system itself. Here are the reasons why Ghost Immobilisers are so hard to detect:
- Hidden Installation: They are typically installed in hidden locations within the vehicle’s wiring, making it challenging for thieves to find and disable them.
- Complex Algorithm: The immobiliser uses a complex algorithm that is nearly impossible for thieves to crack. This algorithm is unique to each device and can be changed regularly to further enhance security.
- No Physical Indicators: Unlike traditional immobilisers that may have visible buttons or indicators, Ghost Immobilisers often have no external signs of their presence. This makes it difficult for thieves to even know if a system is installed.
- Wireless Communication: Many Ghost Immobilisers use wireless communication to connect with other components in the vehicle. This eliminates the need for physical wires, making it even harder to detect and bypass.
- Regular Updates: Manufacturers often release software updates for their Ghost Immobilisers to address security vulnerabilities and improve their effectiveness. This means that even if a thief were to temporarily disable the system, it could be reactivated with a simple update.
How are Ghost Immobilisers installed?
A professional technician typically installs a Ghost Immobiliser. The installation process involves connecting the device to various components within the vehicle’s electrical system, such as the engine control unit (ECU).
Here are the general steps involved in installing a Ghost Immobiliser:
- Vehicle Assessment: The technician will assess your vehicle to determine the best location for the immobiliser’s main unit and to identify the necessary wiring connections.
- Hidden Installation: The device is usually installed in a hidden location, such as under the dashboard or behind the centre console. This makes it difficult for thieves to find and disable.
- Wiring Connections: The technician will connect the immobiliser to the ECU and other relevant components using specialised wiring harnesses.
- Programming: The immobiliser is then programmed with a unique PIN code that the owner will need to enter to start the vehicle.
- Testing: The technician will test the immobiliser to ensure it is working correctly and that the vehicle cannot be started without entering the correct PIN code.
Is a Ghost Immobiliser Thatcham approved?
Thatcham Research is a UK-based motor insurance research organisation that provides independent testing and certification of vehicle security systems. They have a rigorous approval process that evaluates the effectiveness of various security measures, including immobilisers.
A Thatcham-approved Ghost Immobiliser means that it has been tested and certified by Thatcham Research to meet their high standards of security. This certification can provide additional peace of mind to car owners, as it indicates that the immobiliser has been thoroughly evaluated and found to be effective in preventing theft.
While many Ghost Immobiliser models are Thatcham-approved, it’s important to verify the specific model you’re considering to ensure it has the necessary certification. Additionally, some insurance companies may offer additional discounts for vehicles equipped with Thatcham-approved security systems.
