Immobilisers: A Complete Guide to Models and Features

Protecting a vehicle from theft has never been more important. An immobiliser works by cutting the engine unless the right code or signal is received, making it far harder for thieves to drive away. Over the years, these devices have become more advanced, with several strong contenders now available in the UK. Each model comes with its own way of operating, different levels of convenience, and varying appeal depending on the driver’s needs. Here’s a side-by-side look at some of the most trusted systems:

Detailed Overview of Each Immobiliser Model

Autowatch Ghost Immobiliser 2

The Ghost II has built a strong reputation as one of the most discreet immobilisers available. Once it’s fitted, there are no lights or obvious components to give it away. To start the car, the driver enters a personal PIN using buttons already in the vehicle, such as those on the steering wheel or dash. A cloned key on its own simply won’t work. It’s a straightforward yet very effective choice for daily drivers and vans.

We previously shared a full review of the Ghost II, which can be found here.

Autowatch Ghost Immobiliser Pro

The Pro takes everything from the Ghost II and adds the convenience of app control. With encrypted communication between the car and the owner’s smartphone, it offers an extra layer of reassurance. Fleet managers in particular find it useful because software updates and settings can be handled more smoothly. The trade-off is cost and the fact that you need to keep the smartphone link active.

StarLine M13

The M13 from StarLine is a flexible bit of kit, particularly appealing to owners of vans or high-end cars. Control is handled via an app, but there’s also the option to add GPS tracking – useful if you want to know exactly where a vehicle is at any time. It also reacts to motion or tilt, alerting the owner if the car is being tampered with. Its functionality makes it a solid choice for fleet vehicles. The only downside for UK customers is that the brand is less of a household name, and everything depends on reliable app use.

Scorpion X-Series

A name long associated with vehicle security in Britain, Scorpion’s X-Series makes use of Bluetooth tags. Keep the tag with you and the system disarms automatically – a convenient touch for drivers who want quick access. There’s also an emergency override in case of issues, and it’s fully compatible with modern CAN-bus systems. It’s user-friendly and insurer-recognised, though some may still prefer the reassurance of a code-based system.

CAN Phantom

The Phantom lives up to its name by being almost impossible to spot. It’s wired directly into the vehicle’s CAN-bus system, leaving nothing visible for a thief to tamper with. To switch it off, the driver enters a custom code through the car’s own buttons. This approach makes it one of the hardest systems to bypass, with Thatcham approval to back it up. The only compromise is the lack of app or tag support – everything runs through the PIN.

Which Immobiliser Should You Choose?

There isn’t a single right answer, as it depends on what matters most to the driver:

• For tech convenience, the Ghost Pro or StarLine M13 are strong picks.
• For stealth and security above all, go with the CAN Phantom.
• For all-round everyday protection, the Ghost II and Scorpion X-Series continue to be safe bets.
