Key Takeaways
• No, not by the usual methods. Relay attacks, key cloning, key theft and diagnostic (OBD) hacking cannot start a car fitted with a Ghost immobiliser.
• Nothing to intercept or jam. The Ghost emits no radio signal, so there is no wireless signature for thieves' tools to find or block.
• Removal doesn't help a thief. The unit is hidden, and even if found and disconnected, the engine still will not start.
• The only real route is towing, and even then the car cannot be driven or started, which is why a Ghost pairs so well with a tracker for recovery.
• The Ghost 2 is TASSA-accredited and should be professionally installed for maximum protection.
To put it simply, thieves cannot bypass the Ghost immobiliser using the methods behind almost all modern car theft: relay attacks, key cloning, key theft or diagnostic hacking. The Autowatch Ghost 2 Immobiliser is a covert, CAN bus device that emits no radio signal, so there is nothing for criminals to intercept, and it will not let the engine start until your unique PIN sequence is entered. No system makes a car impossible to steal outright, a determined gang can still tow a vehicle away, but they cannot drive or start it, which is exactly why a Ghost combined with a tracker is such a strong pairing.
Can Thieves Bypass a Ghost Immobiliser? Method by Method
| Theft method | Does the Ghost stop it? | Why |
|---|---|---|
| Relay attack | Yes | The engine will not start without your PIN sequence, even if the key's signal is captured. |
| Key cloning | Yes | A cloned key still cannot start the car without the sequence. |
| Key theft | Yes | Possessing the physical key alone is not enough to drive away. |
| OBD / diagnostic hacking | Yes | The Ghost has no wireless signature for diagnostic tools to detect or exploit. |
| Signal jamming | Yes | The Ghost emits no radio signal, so there is nothing to jam. |
| Cutting or removing the unit | Yes | It is hidden, and even if found and disconnected the car will not start. |
| Towing the vehicle | Partly | The car can be towed but cannot be driven or started. A tracker enables recovery. |
How Does a Ghost Immobiliser Work?
The Ghost is a covert immobiliser, quite different from a conventional alarm with flashing LEDs and a siren. It integrates directly with your vehicle's Controller Area Network (CAN) bus, communicating with the car's existing electronics without extra wiring that could reveal its location.
To start the car, you enter a unique sequence using the buttons already in the vehicle, on the steering wheel, door panels or centre console. The sequence is fully customisable and can be changed at any time. If it is not entered correctly, the engine will not start. Because there is no physical fob or key involved in this step, there is nothing for a thief to steal, copy or clone.
Can a Thief Hack or Override It?
There is no conventional way to override a Ghost. Because it emits no radio signals, the diagnostic tools criminals use to find and disable other security systems simply have nothing to work with. There is no wireless signature to exploit, and the only way to start the vehicle is to enter the correct sequence.
For legitimate access, if you forget your sequence or need the car serviced, you are given a unique emergency code on a card at installation. Entering it disarms the immobiliser. Only the authorised owner holds this code, so it maintains security while giving you a practical fallback.
Can a Thief Just Remove or "Rip Out" the Ghost?
This is one of the most common questions, and the answer is reassuring. The Ghost is designed to be invisible, with no bulky box or obvious wiring, so a thief has no easy way to identify or locate it. Even if one were found and the wires cut, the car still would not start: because the Ghost sits on the CAN bus as a digital gatekeeper, breaking the circuit typically leaves the vehicle immobile rather than freeing it. Having the device professionally and discreetly installed is what makes this protection so reliable.
Can a Car With a Ghost Be Stolen at All?
Being honest matters here. No immobiliser makes a car completely theft-proof. A determined, well-equipped gang can still lift or tow a vehicle onto a trailer. What they cannot do is drive it away or start the engine, which rules out the quick, quiet getaway that most car theft relies on. This is why the strongest set-up combines a Ghost with a tracker: the Ghost stops the car being driven, and a tracker lets it be located and recovered if it is ever moved. Browse insurance approved trackers to pair with your Ghost.
Is the Ghost Immobiliser Insurance Approved?
The Autowatch Ghost 2 is TASSA-accredited (the Tracker and Aftermarket Security Systems Association), an industry recognition that supports its credibility with insurers. Some insurers may offer a benefit for a professionally fitted, high-quality immobiliser, though this varies, so it is worth checking with yours. Professional installation by an approved fitter also ensures the system is set up and hidden correctly from day one.
Why the Ghost Is Such a Strong Deterrent
Car thieves are opportunistic and look for a quick, quiet getaway. A car that will not start for no apparent reason is the opposite of an easy target: it introduces delay and uncertainty and raises the risk of being caught. A thief may break into a vehicle in seconds, but when it stubbornly refuses to start, the usual response is to abandon it and move on. That silent, immovable resistance is often a more effective deterrent than a loud alarm, which can be ignored or quickly silenced.

Frequently Asked Questions
Can a Ghost immobiliser be hacked? No. The Ghost emits no radio signal, so there is no wireless signature for diagnostic or hacking tools to detect or exploit. The car will only start once the correct PIN sequence is entered.
Can a thief remove or bypass a Ghost immobiliser? The unit is hidden and difficult to find. Even if a thief located and disconnected it, the car would still not start, because breaking the CAN bus circuit leaves the vehicle immobile rather than freeing it.
Can a car with a Ghost immobiliser be towed away? Physically, yes, a car can be towed, but it cannot be driven or started without the sequence. Pairing a Ghost with a tracker means the vehicle can be located and recovered if it is moved.
Does the Ghost immobiliser stop relay attacks and key cloning? Yes. Because starting the car requires your PIN sequence rather than a key signal, a relay attack or a cloned key cannot drive the vehicle away.
What happens if I forget my Ghost immobiliser code? You are given a unique emergency code on a card at installation. Entering it disarms the system, so only you, as the authorised owner, can regain access.
Is the Autowatch Ghost immobiliser insurance approved? The Ghost 2 is TASSA-accredited. Some insurers may offer a benefit for a professionally fitted immobiliser, but this varies, so check with your insurer.
