Ghost Immobilisers & Vehicle Security
Autowatch Ghost immobiliser installation, OBD port protection and security packages that stop key cloning and relay attacks.
Vehicle theft in Melbourne is at record levels — and modern theft techniques have made traditional security measures almost useless. Key cloning, relay attacks and OBD port hacking mean a sophisticated thief can steal a modern vehicle in under 30 seconds. At National AutoTec we install ghost immobilisers and OBD port protection that stop these attacks, even when a thief has your key or has cloned its signal.
Ghost Immobiliser Supply & Installation The Autowatch Ghost 2 is the world's first aftermarket CAN bus immobiliser — and the most effective vehicle security device available today. Unlike traditional alarms or visible security devices, the Ghost is completely hidden within your vehicle's wiring with no visible components, key fobs or LED indicators. To start the vehicle, the driver enters a secret PIN sequence using existing buttons already in the car — steering wheel controls, window switches or dashboard buttons. Without the correct sequence, the engine will not start — even if the thief has the physical key, has cloned the key signal or has accessed the OBD port. The only way to move a Ghost protected vehicle is to tow it — and even then it can never be driven without the PIN.
Ghost immobiliser installation is particularly recommended for:
- Prestige and European vehicles — BMW, Mercedes, Audi, Porsche, Land Rover
- Toyota Landcruiser and HiLux
- Keyless entry vehicles vulnerable to relay attacks
- Fleet vehicles
- Any vehicle in a high theft area of Melbourne
OBD Port Protection Physical OBD port protection devices prevent thieves from accessing your vehicle's electronic systems through the diagnostic port — an increasingly common theft method on modern vehicles. Supply and installation available.
Stolen Vehicle Security Packages Complete vehicle security packages combining ghost immobiliser installation, GPS tracker programming and OBD port protection — providing multiple layers of security against modern theft techniques. Ideal for prestige vehicle owners and high value fleet vehicles.
