Scorpion X Immobiliser

Scorpion X is a CAN bus immobiliser, it sits invisibly on your car's own internal data network rather than adding any external box, fob, or transmitter. Every time you turn the ignition off, it arms itself automatically. To start the car again, you enter a short PIN sequence using buttons already built into your dashboard or steering wheel, the same volume, mode, or menu buttons you already use.

That's what makes it different from a standard alarm or a tag-based system. A relay attack works by capturing and copying the signal from a key fob. Scorpion X has no fob signal to capture, there's simply nothing to relay. Even if a thief gets the doors open and the ignition turns over, the engine won't run without the correct sequence, entered by hand.

It's built specifically with this threat in mind: Scorpion Automotive designed the X-Series around defeating exactly the key relay and cloning techniques that account for the majority of UK car theft now. Manufacturer, over 50 years in vehicle security.
