Frequently Asked Questions
How does a CAN bus immobiliser stop keyless theft and relay crime?
A modern Ghost 2 immobiliser blocks the engine from starting until you enter your chosen PIN sequence. You press a set pattern using existing buttons in your car, such as those on the steering wheel or dashboard.
This system connects to your vehicle’s CAN bus network. It does not rely on a separate key fob signal to start the engine.
Relay attacks and key cloning copy or extend your key’s signal. The immobiliser still prevents the engine from starting because thieves do not know your PIN sequence.
In simple terms:
- A thief may unlock the car.
- They may even clone the key.
- They still cannot start the engine without your code.

Can criminals get around a CAN bus immobiliser, and what are the risks?
No system is completely immune to attack. However, a properly fitted Ghost 2 has no visible wiring, LED lights, or radio signal that makes it easy to detect.
It does not broadcast a signal, so common scanning tools cannot find it. This makes bypassing it more difficult than older alarm systems.
Known risks usually involve:
- Poor installation
- Incorrect wiring
- Access to the vehicle’s internal systems
You reduce risk by using an approved and experienced installer.
What problems can appear after installation, and what should you look for?
A correct installation should not affect normal driving. Your vehicle should start and operate as usual once you enter your PIN.
Warning signs of a problem include:
- The engine fails to start even after entering the correct code
- Warning lights appear on the dashboard
- Buttons do not respond correctly during PIN entry
If you notice these issues, contact your installer. Do not attempt to rewire or remove the system yourself.
What sets first-generation systems apart from second-generation versions?
First-generation systems introduced the PIN-based start block linked to the CAN bus network.
Second-generation versions, such as Ghost 2, improved on this design with:
- Faster processing
- Broader vehicle compatibility
- Enhanced resistance to new theft methods
Later versions are also smaller, making them easier to hide within the vehicle.
Do UK insurers accept this immobiliser, and what proof do they require?
Many UK insurers recognise CAN bus immobilisers, such as the Ghost 2, as an added security measure. Some may offer a premium reduction.
Insurers often ask for:
- A certificate of installation
- Proof that an approved installer fitted the system
- Confirmation of the exact product model
You should inform your insurer after installation to ensure your policy reflects the added security.

How do you pair, replace, or fix issues with the app or fob?
Some versions support a mobile app or paired device for secure disarm features. Pairing usually involves entering your PIN and following the setup steps provided by the installer.
If you replace your phone or fob, you normally need to:
- Enter your existing PIN.
- Access the pairing mode.
- Authorise the new device.
If the app fails to connect or the fob does not respond, check the battery first. If problems persist, contact your installer to reset or reconfigure the system safely.
