Casper Ghost Immobiliser: Invisible, Button-Sequence Protection
The Casper Ghost Immobiliser stops your vehicle from starting unless a personal sequence of steering-wheel button presses is entered first. There's no visible unit, no wiring changes a thief can spot, and no key fob or tag to lose or clone — just a sequence only you know.
How it works
The immobiliser connects into your vehicle's CAN-BUS system. Start the car normally and nothing happens without your button sequence entered first; get the sequence wrong, and the immobiliser keeps the engine from starting. Because there's no visible switch or indicator, there's nothing for a thief to search for or disable.
- Invisible installation — no visible switches or indicators
- CAN-BUS integration — no cutting or splicing of your vehicle's original wiring
- Personal button-sequence unlock via the steering wheel
- Universal fit — cars, vans and motorcycles
- Professional installation included

Why a button sequence instead of a tag
If you'd rather not carry an extra tag or fob, the Ghost Immobiliser's sequence-based unlock means there's nothing physical to lose, forget, or have cloned — the security lives entirely in something only you know. (If you'd prefer tag-based "No Tag, No Start" immobilisation instead, that's what our Casper Pro handles.)
Installation
Fitted by our professional installers directly into your vehicle's CAN-BUS system, with your original wiring and architecture left untouched — nothing is cut or rerouted.
Compatibility
The Ghost Immobiliser fits a wide range of cars, vans and motorcycles. Get in touch with your vehicle's make and model and we'll confirm compatibility before you order.

Common questions
Before you order a Thatcham tracker
How do I know if I need S7 or S5?
Read the tracker clause on your insurance schedule. If it only says Thatcham-approved, S7 usually meets it. If it names S5 or Category 5, fit S5 or S5 PLUS.
Will insurers accept the certificate?
Every system we supply is Thatcham-certified S7, S5 or S5 PLUS. A digital certificate is issued when the job is finished and is recognised by major UK insurers including Admiral, LV=, Direct Line, Aviva, AXA, Churchill and Hastings.
Do you fit nationwide?
Yes. More than 250 Thatcham-accredited engineers cover UK postcodes. Appointments are at home or work. Free fitting is available in major areas.
How fast is the certificate issued?
The official digital certificate is available in the app as soon as the engineer signs the job off.
What is the difference between S5 and S5 PLUS?
S5 adds Automatic Driver Recognition to the S7 tracking spec. S5 PLUS adds engine immobilisation on top of S5.
