Thatcham-certified hardware
S7, S5 or S5 PLUS — match the category printed on your insurance schedule.
The Casper Pro stops your vehicle from starting unless an authorised tag is present in the car. No tag, no start — simple as that. It's the tag-based counterpart to our sequence-based Casper Ghost Immobiliser, for owners who'd rather carry a tag than remember a button sequence.
How it works
Installed directly into your vehicle's electrical system by a professional, the Casper Pro monitors for your authorised tag whenever the engine is started. With the tag present, the car starts normally. Without it, the immobiliser keeps the engine from running — so even with the correct key, a thief without the tag can't drive away.
Why choose tag-based over sequence-based
If you'd rather not memorise a button sequence, carrying a tag is the simpler day-to-day option — leave it in the car (or on your keys) and the Casper Pro handles the rest. Prefer nothing physical to carry at all? Our Casper Ghost Immobiliser uses a steering-wheel sequence instead.
Installation
Fitting is arranged for you — just give us three preferred install dates and we'll take care of the rest. Installation typically takes around an hour, carried out by a qualified professional with your vehicle's original wiring left intact.
Support
Our team is on hand if you have questions about setup or day-to-day use once your Casper Pro is installed.
