  • What Is a Vehicle Immobiliser and Why Should You Use One?

    A vehicle immobiliser is an electronic anti-theft device that disrupts the starter, ignition, or fuel system, preventing the engine or powertrain from running unless it recognises the correct coded key, fob, or secret PIN. When factory-fitted immobilisers were made mandatory in 1988, they significantly reduced vehicle thefts by over 40%. However, since then, both vehicle technology and theft methods have evolved. With the rise of software-driven automotive systems, factory-fitted immobilisers have become less effective and can be easily compromised with modern theft techniques.

    To combat today's digital theft challenges, modern aftermarket engine immobilisers, especially when paired with a professional GPS tracker, are essential. This combination not only prevents theft but also aids in vehicle recovery. Because the immobiliser operates on a different logic channel than factory security systems, sophisticated techniques used by thieves to bypass factory equipment are often ineffective. If you're searching for the best car immobiliser in the UK, this setup offers unbeatable protection.

Immobilisers - Frequently Asked Questions

  • The immobiliser keeps the starter or an alternative circuit disabled until it authenticates your unique driver ID tag, so a cloned key signal cannot start the engine.

  • A stand-alone engine immobiliser is designed to prevent theft by providing an extra layer of authentication for starting your vehicle. However, it does not allow you to track or recover the vehicle if it is stolen, particularly in situations where your ID tag might be stolen from you.

    By pairing your engine immobiliser with a GPS car tracker, you can enhance its functionality. This combination offers features such as remote shutdown of your vehicle in the event of theft, live GPS tracking data, professional theft support, and an emergency support option. This emergency option can help disarm your engine immobiliser if you lose your ID tag or if its battery runs out.

  • Absolutely. Our Thatcham-accredited, insurance-approved vehicle immobiliser systems meet insurer specifications and can lower premiums.

  • Modern immobilisers draw only milliamps, negligible on a healthy battery, so routine driving keeps everything charged. Even if you're not driving your vehicle regularly, the load of your vehicle battery is so low that it would take many, many months to have any sort of impact. In fact, your vehicles factory electronics would be draining your battery faster than any aftermarket immobiliser or tracker system would be.

  • Most installs take 45 minutes to two hours, depending on car model and whether you add a Thatcham S5 car tracker immobiliser.

  • While DIY installation is possible, it can be risky. To ensure your system is Thatcham Approved and meets the requirements of vehicle insurance companies, it must be installed by a qualified professional. A professional installation also guarantees the highest standards of workmanship, which is crucial in the event of a theft, especially if thieves specifically target your system. Covert installations by professionals are vital and are associated with higher recovery rates for stolen vehicles.

  • Yes. Our GPS units utilise multi-roaming SIMS and provide professional theft recovery services across Europe. Provided you and your fitted system have access to an internet connection, you’ll be able to communicate with your vehicle/system from anywhere in the world. Whether that be to see recent activity, ignition on/off status/recent trips, or even to remotely immobilise the vehicle, you can do this from anywhere in the world, provided you have an internet connection.

  • For stand-alone immobilisers, you can use the emergency override procedure. This procedure involves inputting a visual PIN. When your device is initially set up, it will come with a 3-digit PIN. Follow the step-by-step instructions for the emergency override to input this PIN into your immobiliser using the override button that’s mounted within the vehicle. This will manually disarm your immobiliser, and you’ll be on your way again, even if your ID tag is not present.

     

    If you have a tracker and immobiliser system, the process is a bit easier. If you have lost your ID tag, simply open the brand app and send a disarm command to the vehicle/system. This will disarm the immobiliser, allowing you to drive away even without the ID tag. If you have no phone signal, navigate through the brand app to the emergency unlock procedure to disarm your immobiliser locally via Bluetooth. If you don’t have a phone, find someone else who does to call your security hardware brand directly. They will be able to remotely disarm your immobiliser for you.

  • We always recommend that customers install both a tracker and an immobiliser in their vehicles. This combination provides the best protection against theft and ensures a professional recovery service if theft occurs.

    If installation of a tracker and immobiliser isn't possible due to budget constraints, we would most likely recommend installing a standalone immobiliser instead of a tracker. We believe that preventing theft is more important than recovering a stolen vehicle, as prevention puts you in a stronger position. While fitting just an immobiliser has its downsides, we believe it is a better option than installing a tracker alone.
