Sterling Excel Immobiliser 

It is a trusted, Thatcham Category 2 approved security system that offers solid, dependable protection for your vehicle. Using advanced coded key technology, it immobilises the engine when the ignition is switched off, preventing unauthorised starting without the correct electronic key.

Recognised by insurers across the UK, the Sterling Excel provides the reassurance of Thatcham-tested performance — helping to deter theft and reduce the risk of vehicle loss. Its straightforward, automatic operation makes it suitable for both modern and classic vehicles, ensuring effective protection without complicated settings or maintenance.

Built to exacting standards and rigorously tested for reliability, the system integrates seamlessly with your vehicle’s existing electronics for smooth and silent operation. It’s an ideal upgrade for vehicles that do not already have a Thatcham-approved immobiliser fitted, or for drivers seeking enhanced protection.

Installation is carried out nationwide by accredited engineers and is included free of charge, ensuring the system is fitted professionally for maximum reliability and compliance with insurance requirements.
