Autowatch Ghost Immobiliser

The Ghost is a CAN bus immobiliser, it connects invisibly into your car's own internal wiring network rather than adding any external unit. Once fitted, it arms itself automatically every time you turn the ignition off. To start the car again, you enter a short PIN sequence on buttons already in your vehicle, steering wheel controls, door panel buttons, or the centre console, whichever the installer sets it to.

There's no fob to carry, clone, or leave in the house. No tag on your keyring for a thief to detect. Because a relay attack works by capturing and replaying a fob's signal, and the Ghost has no signal to capture in the first place, the attack simply has nothing to grab onto. Even with your actual key in hand, the engine won't run without the correct sequence.

Autowatch is the longest-established name in this category in the UK, and TASSA registration means every fitting comes with a certificate you can hand to your insurer.
