Advanced Car Security Guide
Car thieves are getting smarter every day. They can clone your keys, hack your car’s computer, and steal your vehicle in minutes without you even knowing. Standard factory security just isn’t enough anymore.
The Autowatch Ghost 2 Immobiliser Pro stops thieves by requiring you to enter a secret code on your car’s existing buttons before the engine starts. This system works quietly in the background through your vehicle’s CAN bus network. No one can see it, and there are no extra key fobs for criminals to copy or steal.
The Autowatch Ghost 2 Immobiliser Pro gives you complete control over your car’s security. You create your own button sequence using controls already fitted in your vehicle, like steering wheel buttons or dashboard switches. When you need to take your car to a garage, you can switch on service mode so mechanics can work without your code.
Key Takeaways
- The Ghost 2 Pro immobiliser prevents key cloning and relay theft by requiring a hidden PIN sequence that you enter using your vehicle’s factory buttons.
- The system integrates invisibly with your car’s CAN bus network and includes a service mode for garage visits.
- TASSA-verified protection works with a wide range of vehicle makes and models to stop modern theft methods.s
Key Features and Operation
The Autowatch Ghost 2 Immobiliser Pro combines multiple layers of protection through its dual immobilisation system, unique disarm sequence, and invisible CAN integration. These features work together to prevent key cloning, relay theft, and unauthorised vehicle access whilst maintaining complete stealth.
Dual Immobilisation Technology
The Ghost 2 Pro immobiliser uses a two-stage driver authorisation system that creates dual layers of security for your vehicle. This means you must complete two separate verification steps before the engine will start.
The first stage requires you to enter your unique PIN code through your vehicle’s existing buttons. The second stage uses ADR tag technology, which works through proximity detection. Both stages must be satisfied before the immobiliser releases control of your vehicle.
This dual approach ensures that even if someone discovers your PIN code, they cannot start your car without the physical ADR tag present. The system prevents the engine from starting by blocking signals on your vehicle’s CAN network, making it impossible for thieves to bypass through traditional hot-wiring or key programming methods.

Disarm Sequence and PIN Code Setup
Your disarm sequence consists of a unique PIN code, created during installation, that you enter with 4 to 20 button presses. You enter this code using your vehicle’s standard buttons, such as steering wheel controls or window switches.
To disarm the Ghost immobiliser and start your vehicle, you must first switch on the ignition without starting the engine. Enter your disarm sequence using your chosen buttons. Wait for your selected indication signal (a specific dashboard light) to flash twice. You can then start the engine normally.
Changing Your PIN Code:
- Switch the ignition on
- Enter your current disarm sequence
- Press and hold the accelerator pedal to the floor
- Enter your current sequence again (dash light flashes every 3 seconds)
- Release the accelerator
- Enter your new sequence
- Wait for 3 flashes
- Re-enter the new sequence to confirm
- Two flashes confirm success; four flashes mean you must restart
You can also pair a smartphone or key fob to disarm the system automatically when you enter the vehicle. The Ghost-II automatically detects the paired device and disarms when you switch on the ignition.
CAN Integration and Stealth Security
The Ghost 2 immobiliser connects directly to your vehicle’s CAN bus, enabling it to communicate with your car’s electronics without cutting any wires or adding visible components. This integration method makes the device completely undetectable to thieves using diagnostic tools or scanner equipment.
The system has no LED indicators, key fobs, or radio frequency signals that thieves could intercept. Your vehicle appears completely standard from the outside and inside. The Ghost immobiliser blocks engine start commands at the CAN level, which means traditional bypass methods cannot work.
Because the device integrates through your vehicle’s existing wiring harness, it leaves no trace that aftermarket car security has been installed. Even experienced thieves using professional diagnostic equipment cannot locate or turn off the Ghost-II system.
Service and Valet Modes
Service mode allows you to temporarily turn off the Ghost 2 immobiliser when you need to leave your vehicle with mechanics or valet staff. This means you don’t need to share your secret disarm sequence with anyone.
To Enter Service Mode:
- Disarm the system normally and wait for 2 flashes
- Press the service button 5 times
- Your indication signal flashes 5 times to confirm activation
To Exit Service Mode:
You can manually exit by entering your disarm sequence whilst the ignition is on. The system also automatically exits service mode if you drive at 32 mph (50 km/h) or faster for more than 15 minutes.
If you forget your PIN code or a button fails, you can use the emergency code printed on your emergency card. Press and hold the brake pedal, then press the accelerator the number of times shown for each digit of your 4-digit emergency code. Release the brake between each digit. This enters Learn Mode, allowing you to set a new disarm sequence or drive the vehicle.
Installation, Support, and Best Practices
Professional installation and proper management of your Ghost 2 Immobiliser ensures maximum protection for your vehicle. Understanding the installation process, emergency procedures, and daily best practices helps you get the most from this security system.

Immobiliser Installation Process
Ghost immobiliser installation typically takes two to three hours to complete. The device connects directly to your vehicle’s CAN bus system without any physical modifications to the wiring loom.
A trained technician will mount the small control unit in a hidden location within your vehicle. They’ll then programme your unique PIN sequence during setup. The installation leaves no visible signs, which prevents thieves from detecting the system.
You won’t need to worry about cutting wires or adding extra parts to your dashboard. The Ghost 2 integrates seamlessly with your vehicle’s existing electronics. After installation, your vehicle will look exactly as it did before, maintaining its factory appearance.
The technician will test the system thoroughly before handing over your vehicle. They’ll verify that all buttons work correctly and that your PIN sequence disarms the immobiliser properly.
Choosing an Autowatch Approved Installer
Please use only an Autowatch-approved installer for your ghost installations. These technicians receive specific training on the Ghost system and hold TASSA approval for their work.
Approved installers understand the technical requirements for different vehicle makes and models. They know where to position the control unit for maximum security and how to integrate it properly with your vehicle’s electronics.
Most approved installers offer mobile fitting services at your home or workplace. This convenience means you don’t need to visit a workshop or leave your vehicle overnight. Professional installers also provide warranties on their work, giving you peace of mind.
You can verify an installer’s credentials through the Autowatch website or by requesting their TASSA certification. Never use an uncertified installer, as improper installation can compromise your vehicle’s security.
Emergency Procedures and Code Management
Your emergency card contains a unique emergency code for situations where you’ve forgotten your PIN sequence. Store this card in a secure location away from your vehicle, such as at home in a safe.
If you forget your PIN, you’ll need the emergency code to temporarily override the system. This code lets you start your vehicle without entering your usual PIN sequence. You should contact your installer afterwards to reset your PIN to a memorable one.
Never keep your emergency card in your vehicle or share it with unauthorised people. If someone steals your vehicle along with the emergency card, they could bypass the immobiliser.
You can change your PIN sequence at any time through your installer. Consider updating it periodically or if you suspect someone may have observed you entering it.
Maintaining and Securing Your Vehicle
The Ghost 2 requires no ongoing maintenance or subscription fees once installed. However, you should follow certain practices to effectively secure your vehicle.
Enter your PIN sequence discreetly when disarming the immobiliser. Shield the buttons from view to prevent others from learning your code. Vary where you park when possible, as thieves sometimes watch vehicles in the same location repeatedly.
If you sell your vehicle, contact your installer to have the system transferred or removed. The new owner will need their own PIN sequence programmed for security purposes.
Keep your installer’s contact details saved in case you need support. Most installers offer technical assistance if you experience any issues with the system. Battery disconnections or vehicle servicing won’t affect the immobiliser’s programming, so you don’t need to take special precautions during routine maintenance.
Frequently Asked Questions
Installation costs typically range from £400 to £600, and the Pro version adds smartphone app control to the standard Ghost 2 model. Most drivers report high satisfaction with the system’s ability to prevent keyless theft, though proper installation by approved fitters remains essential.
How much does the installation typically cost, and what affects the final price?
Professional installation by a TASSA-approved fitter costs between £400 and £600 on average. The final price depends on your vehicle’s make and model, your location, and the complexity of the installation.
Some vehicles require more time to install due to their internal layout. Luxury and performance cars may cost more because installers need more time to integrate the system properly.
The price usually includes the device, installation, setup of your unique PIN code, and a demonstration of how to use it. Most installations are complete within two to four hours.

What are the key differences between the standard model and the Pro version?
The Ghost 2 Pro includes smartphone app control, whilst the standard Ghost 2 does not. Both versions use the same core technology to prevent your vehicle from starting unless the correct PIN sequence is entered.
With the Pro version, you can use your phone to disarm the system remotely. This feature helps if you need a valet or mechanic to move your car without revealing your PIN code.
The standard model requires you to enter your PIN sequence every time using your vehicle’s existing buttons. Both versions offer the same level of security against key cloning and relay attacks.
How effective is it in real-world use, and is it worth fitting?
The Ghost 2 immobiliser prevents your engine from starting even when thieves have your keys. It stops keyless relay attacks, key cloning, and unauthorised ECU reprogramming.
Keyless vehicle theft continues to rise across the UK. Traditional alarms only alert you after a theft attempt begins, but the Ghost 2 stops thieves before they can drive away.
Insurance companies recognise TASSA-approved immobilisers, and many offer premium discounts. Some insurers now require additional security devices for high-risk vehicles.
The system requires no maintenance once installed. You enter your PIN before driving, and it becomes routine after a few days of use.
Can thieves bypass this type of immobiliser, and what common attack methods should you consider?
The Ghost 2 cannot be bypassed through key cloning, signal relay attacks, or diagnostic port hacking. It has no radio signals for thieves to intercept and no physical components they can remove quickly.
Thieves using headlight hacking or CAN bus injection still cannot start your vehicle without the correct PIN sequence. The system blocks the engine even when criminals inject code directly into the vehicle’s network.
The immobiliser remains completely hidden with no visible signs of installation. Thieves cannot tell your vehicle has the system fitted, which often makes them move on to easier targets.
Physical vehicle theft through towing remains possible with any security system. However, combining the Ghost 2 with a tracker provides both prevention and recovery options.
How does it compare with other popular aftermarket immobilisers in terms of security and usability?
Most aftermarket immobilisers use key fobs or physical switches that thieves can locate and bypass. The Ghost 2 uses your vehicle’s existing buttons and creates a unique sequence you choose.
Traditional immobilisers often rely on radio signals that sophisticated thieves can intercept. The Ghost 2 communicates directly through your vehicle’s CAN bus network without any external signals.
Other systems may require visible LED indicators or physical cut-off switches—the Ghost 2 installs completely out of sight with no modifications to your dashboard or interior.
You enter your PIN using controls already in your vehicle, such as steering wheel buttons or dashboard controls. This makes it simple to use whilst remaining invisible to potential thieves.

Will it affect vehicle warranty, insurance cover, or servicing requirements?
The Ghost 2 installation does not cut any factory wiring, which helps preserve your manufacturer’s warranty. TASSA-approved installers follow strict guidelines to ensure the system integrates without affecting original components.
You should inform your insurance company about the installation. Many insurers offer premium discounts for TASSA-approved security devices, and some may reduce your excess.
The system does not interfere with standard servicing or MOT tests. Your mechanic can work on your vehicle as usual, though you may need to provide them with a service mode or a temporary PIN.
Main dealers can perform diagnostics and updates without issues. The Ghost 2 operates independently from your vehicle’s standard systems and does not trigger warning lights or error codes.
