Ghost Immobiliser Cost in 2026 & Top Alternatives
Share
A Ghost immobiliser typically costs £499 fully fitted in 2026, with prices ranging from £449 to £599 depending on the model, vehicle type and any extras you add on top. That figure usually covers the device itself, professional mobile installation anywhere in the UK, and VAT, though optional add-ons like a key tag or GPS tracker bundle can push the total closer to £700-£975.
What Affects Ghost Immobiliser Pricing
Several factors influence what you'll actually pay on the day of fitting, and it rarely comes down to the base unit alone.
- Vehicle make and model: some cars need extra wiring work, which can add labour time
- Package tier: a basic Ghost II sits around £449-£499, while the Ghost Pro version runs closer to £599
- Bundled tracking: combining the immobiliser with an insurance-approved tracker like an S5 or S7 can take the total to £698-£975
- Key tag add-on: an optional physical tag for easier starting typically costs an extra £50-£60
- Warranty extras: a lifetime parts and labour warranty is often offered for around £49-£99 on top
Is There an Ongoing Subscription Cost for Ghost Immobiliser?
One thing that catches a lot of buyers out is the small print around subscriptions. While the core Ghost immobiliser itself has no recurring fee, many installers bundle it with a tracker that does carry an annual or monthly charge, sometimes £139-£189 a year, or £4.99-£16.99 a month. If you're only after the immobiliser function with no data plan attached, it pays to check exactly what's included before you book, since some quotes hide the tracker subscription in the small print rather than the headline price.
How a Ghost Immobiliser Actually Works
Rather than relying on a visible alarm, siren or flashing light, a Ghost-style device connects directly into your vehicle's CAN bus network, the internal system that lets all its electronic components talk to each other. Once fitted, the car simply won't start unless a secret sequence of button presses is entered on the existing steering wheel or dashboard controls, meaning there's no fob to clone, no aerial to jam, and nothing for a thief to spot on the exterior.
This approach has become popular precisely because modern car theft methods, like relay attacks and key cloning, are largely ineffective against a device with no signal to intercept and no physical key to copy.
Cost of Ghost Immobiliser vs. a Cheaper Ghost Alternative
If the £499-plus price tag of a standard Ghost immobiliser feels steep, GPSBob's Casper range delivers the same CAN bus based, invisible protection from just £399, with professional installation included as standard rather than charged separately.
Both Casper models are designed to be completely undetectable, with no wiring changes to your original vehicle, no visible fobs, and no monthly subscription tying you into ongoing costs, which fits GPSBob's broader no-hidden-fees approach across its whole tracker range.
Casper: The Ghost-Like Car Immobiliser (£399)
The standard Casper is a one-time payment of £399 with installation included, making it roughly £100 cheaper than a standard Ghost fit. It uses a secret button-press sequence on the steering wheel, works across a wide range of cars, vans and motorcycles, and leaves your vehicle's original wiring and architecture completely untouched during fitting.
Casper Pro: No Tag, No Start (£499)
The Casper Pro sits at £499, matching Ghost's standard price point but adding a proximity tag system on top of the CAN bus protection. Rather than remembering a code, the car recognises the tag automatically when it's nearby and lets you drive off as normal, while the engine stays completely inoperative if that tag isn't present, adding anti-scan technology that blocks common relay-style theft attempts.

Frequently Asked Questions
Does a ghost immobiliser affect insurance premiums?
Many insurers offer discounts once a Thatcham-approved or CAN bus immobiliser is fitted, since it lowers the statistical risk of theft, though the exact saving depends on your provider and vehicle type.
Can a ghost immobiliser be fitted to any car?
Most modern vehicles with a CAN bus system are compatible, but very old cars without this network, or some hybrid and EV models, may need a specialist check before fitting.
Will fitting an immobiliser void my manufacturer warranty?
No, a properly installed CAN bus immobiliser like Casper connects without cutting or altering the original wiring, so it shouldn't invalidate your manufacturer's warranty.
How long does installation take?
Professional fitting for a CAN bus immobiliser typically takes around one hour, whether it's a Ghost unit or a Casper device, and is usually done at your home or workplace.
What happens if I forget my code or lose my tag?
Reputable providers offer backup access methods, such as a secondary code entry process or replacement tag, so you're never permanently locked out of your own vehicle.
