    Why a Faraday cage is so useful in preventing keyless theft

    Keyless car theft

    In today’s modern world, technology has made our lives more convenient in many ways, but it has also introduced new challenges, particularly in the realm of vehicle security. One such challenge is keyless car theft, a method increasingly utilised by thieves to steal vehicles with minimal effort. Thankfully, it can be easily mitigated by a few simple measures, including Faraday cages. It’s also a good idea to look at a few more complementary (and equally effective) measures, such as bollards and driveway posts.

    What is keyless car theft?

    Keyless car theft, also known as relay theft, is a sophisticated method used by criminals to gain unauthorised access to vehicles equipped with keyless entry systems. These systems allow drivers to unlock and start their vehicles without physically using the key fob. Instead, the key fob emits a signal that is detected by the vehicle when it is within close proximity, typically a few metres. However, thieves have developed devices that can capture and amplify these signals, allowing them to unlock and start vehicles remotely, often in a matter of seconds, without the owner’s knowledge.

    Why is it such a big risk?

    Keyless car theft presents a significant risk to largely due to the its discretion, and the ease with which thieves can execute it. Unlike traditional car theft methods that may involve forced entry or hotwiring, keyless car theft can be carried out with minimal physical effort and leaves no visible signs of tampering. What’s more, the widespread availability of relay devices and the relatively simple techniques required to use them make this method appealing to opportunistic criminals.

    As a result, keyless car theft has become increasingly prevalent, with reports of incidents rising across the UK and beyond. Somewhat notoriously, 2023 was the worst year on record for keyless thefts.

    How Faraday cages prevent vehicle theft

    Faraday cages are crucial in preventing keyless theft mainly because they block electromagnetic fields and signals. Keyless entry systems operate using radio frequency signals, which can be intercepted and exploited by thieves using relay devices. However, Faraday cages, made of conductive materials like metal mesh or carbon fibre, effectively block these signals, preventing them from reaching the key fob and thereby thwarting attempts at relay theft. By storing your key fob inside a Faraday cage when it’s not in use, you can ensure that it remains protected from unauthorised access and reduce the risk of your vehicle being stolen.

    3 other effective security measures

    While keyless car theft poses a formidable challenge, you’re thankfully not short of security measures that you can use to protect their car. In addition to Faraday cages, which we will explore in more detail shortly, other effective security measures include the below.

    Alarm systems

    Alarm systems are designed to detect unauthorised access to vehicles and deter thieves with loud sirens and flashing lights. Modern alarm systems often include motion sensors, glass break detectors, and other features to enhance security.

    Surveillance cameras

    Installing surveillance cameras in parking areas provides an additional layer of security by capturing footage of any suspicious activity. Cameras act as a deterrent to potential thieves and provide valuable evidence in the event of a theft attempt.

    Driveway bollards

    Installing bollards around parking areas can create physical barriers to prevent unauthorised access to vehicles. These sturdy posts act as a deterrent to thieves and make it more difficult for them to steal cars, especially in high-traffic areas.
