What is the Autowatch Ghost Immobiliser?
In the world of vehicle security, Autowatch is a leading brand trusted by UK drivers to protect their valuable assets. The Autowatch Ghost Immobiliser represents the next generation of vehicle protection. It is a discreet, aftermarket CAN bus immobiliser designed with a single primary function: preventing your vehicle’s engine from starting without a unique, user-defined PIN code.
This PIN code is entered using your car’s existing buttons on the steering wheel, door panels, or centre console. Until this sequence is correctly entered, your vehicle remains immobilised.
Crucially, the Ghost is not a traditional car alarm; it makes no sound and gives no visual indication of its presence. It is also not a GPS tracker. Its purpose is purely preventative. While standard car immobiliser technology has been effective for years, it often relies on key fobs, which are now the primary target of thieves. The Ghost bypasses this vulnerability entirely, offering a silent, robust defence against modern theft techniques.
The Rise of Keyless Car Theft
Modern vehicles with keyless entry are prime targets for sophisticated criminals. Using techniques like relay attacks, thieves can capture and amplify the signal from your key fob-even from inside your home-to unlock and start your car in seconds. Key cloning is another major threat. The Ghost immobiliser is the definitive answer to this problem. Because it requires a physical PIN to be entered inside the vehicle, it renders signal-based theft methods obsolete.
Key Terminology: CAN Bus Explained
The Controller Area Network (CAN) bus is your vehicle’s internal computer network, managing communication among all its electronic components, from the engine to the electric windows. The Autowatch Ghost integrates seamlessly and covertly into this network. Because it uses the vehicle’s own systems and does not transmit any radio-frequency (RF) signals, it is invisible to the diagnostic tools that thieves use to detect and turn off security devices. This digital integration makes it a true ghost in the machine.
How the Autowatch Ghost Secures Your Vehicle
The Autowatch Ghost immobiliser integrates directly with your vehicle’s Controller Area Network (CAN) data system, making it undetectable to thieves using diagnostic tools. Unlike traditional systems, it requires no additional key fobs or visible components that can be lost, stolen, or cloned. It operates silently in the background, acting as a covert layer of security. The system is a prime example of an advanced Immobilizing-Type Device that physically prevents the engine from starting without authorisation. Without the correct disarm sequence, your vehicle remains completely immobilised.
The Unique Disarm Sequence
Disarming the system is achieved via a unique PIN code sequence that you create and control. This sequence is entered using your car’s existing buttons, creating a personalised code that only you know. You can use a combination of buttons on the:
Steering wheel
Dashboard
Centre console
Door panels (e.g., window or mirror switches)
The sequence can be 4 to 20 presses long and can be changed at any time, ensuring your vehicle’s security is never compromised.
Smartphone App Integration
For added convenience, the Autowatch Ghost can be paired with a companion smartphone app via a secure Bluetooth connection. This feature allows you to disarm the immobiliser automatically without entering a PIN. Have your paired phone with you when you enter the vehicle, and the system will disarm, allowing you to start the engine and drive away. Multiple phones can be paired, making it an ideal solution for shared vehicles.
Service/Valet Mode
A common concern is securing vehicles during garage services or valet parking. The Ghost Immobiliser includes a dedicated Service/Valet Mode. By entering a simple command via your vehicle’s buttons, you can temporarily turn off the immobiliser’s functions. This gives mechanics full access to work on your car without you ever needing to reveal your secret PIN. Once you collect your vehicle, you can easily and securely re-enable the system, ensuring your PIN remains confidential, and your car is fully protected again.
Autowatch Ghost vs Traditional Alarms & GPS Trackers
To understand the value of the Autowatch Ghost, it is essential to compare it directly with the two most common types of vehicle security: factory-fitted alarms and aftermarket GPS trackers. While each system has a role, they address different stages of a potential theft. The Ghost operates on a prevention principle, making it a foundational layer of security rather than an alternative.
Ghost Immobiliser vvsCar Alarms
A traditional car alarm is a deterrent. Its primary function is to make a loud noise to attract attention and scare off an opportunistic thief. However, professional criminals can disarm most factory alarms in seconds. Furthermore, in busy urban environments, audible alarms are so common that they are frequently ignored. The Ghost is different. It is a preventative system that physically stops your vehicle’s engine from starting without the correct, unique PIN code. It is silent and invisible, offering no clues to its existence, which means a thief cannot bypass what they cannot find.
Ghost Immobiliser vs GPS Trackers
A GPS tracker is a reactive device. It is designed to help you or the police locate your vehicle after it has already been stolen. While useful for recovery, it does not stop the initial theft, the damage, or the stress that comes with it. The Autowatch Ghost is proactive; it secures your vehicle from the outset, preventing thieves from ever driving it away. Critically, sophisticated thieves now use GPS/GSM jammers to block a tracker’s signal, rendering it useless. The Ghost is immune to jammers as it does not transmit any signal.
The Ultimate Security Combination
For complete peace of mind, security specialists advocate for a layered approach. The Ghost Immobiliser acts as the first line of defence, preventing the vehicle from being started or driven away. A Thatcham-approved GPS tracker, such as an S7 or S5, provides an additional layer of recovery. This combination creates a powerful security solution that covers both prevention and, in the worst case, recovery. In fact, many UK insurance providers now require this dual-layer system for high-value or high-risk vehicles to provide cover. This approach ensures your asset is protected against modern theft techniques.

Is the Autowatch Ghost the Right Choice for You?
Deciding on the right vehicle security is a critical step in protecting your asset. The Autowatch Ghost is a premium, next-generation immobiliser, but is it the necessary solution for your specific circumstances? The answer often depends on your vehicle’s vulnerability, its value (both monetary and personal), and where it is typically parked.
Think of the cost not as an expense, but as a one-time investment in permanent peace of mind. Compared with the cost of an insurance excess, the loss of your vehicle, and the significant inconvenience of theft, the Ghost provides undeniable value.
Ideal Vehicles & Use Cases
While any vehicle can benefit from enhanced security, the Ghost immobiliser is especially suited for those at the highest risk of theft through modern electronic methods. This includes:

Autowatch Ghost: Frequently Asked Questions
Is the Autowatch Ghost a Thatcham-approved device?
The Autowatch Ghost II is not Thatcham-accredited. Thatcham’s criteria require immobilisers to use physical fobs or tags for disarm, which contradicts the Ghost’s core design as a covert, button-based system. While it provides exceptional protection against modern theft methods such as key cloning and relay attacks, it does not qualify for insurance discounts associated with Thatcham approval. For an insurance-approved solution, consider a Thatcham S5 or S7 tracker.
Will installing an Autowatch Ghost void my car’s warranty?
Installing a Ghost immobiliser will not void your vehicle’s warranty, provided a certified, experienced technician fits it. The device is engineered to integrate with your car’s existing CAN bus data network without cutting or splicing any wires. This non-intrusive installation method ensures that the manufacturer’s warranty on electrical systems remains intact. Always use an approved installer to ensure a secure, warranty-compliant fitment.
What happens if I forget my Ghost immobiliser PIN code?
If you forget your disarm sequence, you will not be locked out of your vehicle. Every Ghost immobiliser is supplied with a unique emergency override code printed on a secure card. You can enter this code using a specific sequence to start your car. Once you regain access, you can reset your PIN to a new, memorable sequence. It is vital to keep this emergency card in a safe place, separate from your vehicle.
Can thieves use a scanner to find the Autowatch Ghost?
No, the Autowatch Ghost is designed to be completely undetectable by thieves using radio frequency scanners or diagnostic tools. Unlike traditional alarms or trackers, it does not emit any RF signals that can be intercepted. The device communicates silently via the vehicle’s CAN bus network, leaving no electronic footprint. This stealth design is a key feature, making it virtually impossible for criminals to locate and turn off the system before attempting to steal the car.
How much does it cost to have an Autowatch Ghost fitted in the UK?
The cost for a fully supplied and fitted Autowatch Ghost immobiliser in the UK typically starts from £499. This price includes professional, nationwide installation by a certified technician at your home or workplace. The final cost may vary slightly based on your vehicle model and location. For a precise quote and to confirm compatibility with your car, it is best to contact an approved dealer directly.
Can the Autowatch Ghost be moved to another vehicle?
Yes, the Ghost immobiliser can be removed from your current car and reinstalled in a new one. An accredited installer must perform this process to ensure the device is properly integrated with the new vehicle’s systems and deactivated on the old one. There is a service charge for this removal and refitting process. This makes the Autowatch Ghost a long-term security investment that can move with you as you change cars.
