Ghost immobiliser cost UK 2025, installation price guide and alternatives

The Autowatch Ghost is one of the UK’s most popular aftermarket immobilisers, using the CAN bus to require a PIN sequence before engine start. Professional Ghost installation costs typically range from £400 to £600 fitted by a Trakmaster or Autowatch-approved installer. LockCar’s relay immobiliser starts from £150 fitted and provides a complementary, physically independent layer of protection that operates outside the CAN bus entirely.

Ghost immobiliser typical installation cost

Autowatch Ghost installation in the UK is typically quoted at £400 to £600 for the device and installation from an approved Trakmaster dealer. This price includes the Ghost 2 or Ghost-II unit, professional fitting by a trained installer, and typically a Thatcham S7 certification document for insurance purposes. Some installers charge additional fees for certification processing or for complex vehicle platforms that require extended installation time.

The Ghost price is higher than many consumer immobiliser products because it includes a monitoring centre subscription and the Thatcham certification process, both of which have ongoing costs that the installer passes through in the installation price.

LockCar relay immobiliser cost

LockCar immobiliser hardware ranges from £49 for the i124 entry unit to £259 for the One Plus combined dashcam and GPS unit. Mobile installation at your location starts from £150 fully fitted for the entry wired units and proportionally higher for combined dashcam-GPS-immobiliser systems. There is no mandatory monitoring centre subscription for the immobiliser function.

LockCar IC3ST, the most popular standalone unit, is £139 for hardware and from approximately £139 additionally for installation at your location. Total fitted cost is typically £250 to £300 for the IC3ST, significantly below Ghost installation cost while providing a physically independent relay break that complements any CAN bus immobiliser.

Ghost and LockCar together, the cost case

For vehicle owners in the highest risk categories, fitting both a Ghost and a LockCar relay immobiliser provides the most comprehensive protection available. Ghost typically costs £400 to £600. LockCar IC3ST from £250 to £300 fitted. Combined investment of £650 to £900 for two independent, complementary security layers is justified by the theft risk and potential insurance premium savings on high-value models including Range Rover, BMW, and Toyota Land Cruiser.
