With keyless entry cars becoming increasingly popular, theft risks have evolved.

Modern thieves use signal relay attacks, intercepting key fob signals to unlock and start cars without a physical key. Protecting your vehicle requires understanding how these technologies work and adopting various countermeasures to enhance security.

Below is an in-depth guide to essential strategies for keeping your keyless entry vehicle secure:

Store Key Fobs Safely

Key fobs emit a low-frequency signal to communicate with your vehicle, allowing for convenient entry and ignition. However, this signal can be exploited. Thieves using signal relay devices can capture this signal from outside your home, unlocking and potentially driving off with your car. To reduce this risk, store your fob in a Faraday pouch—a signal-blocking container. This inexpensive pouch blocks electromagnetic signals, preventing thieves from capturing the fob's frequency. Additionally, keep keys away from windows, doors, and walls, as proximity to entry points can increase exposure to signal relays.

Implement Physical Deterrents

Physical deterrents remain highly effective against theft. Steering wheel locks, gear shifter locks, and wheel immobilisers serve as visible and tangible obstacles that can deter potential criminals. Steering wheel locks, for example, require additional time and tools to bypass, making your vehicle less appealing. Immobilisers add another layer of security by locking essential vehicle functions, like the fuel system, which prevents the car from starting. Despite being simple, these tools can significantly increase the time required for theft, dissuading many criminals.

Invest in Advanced Anti-Theft Technologies

Modern anti-theft technologies offer sophisticated solutions that can provide real-time alerts and tracking if a theft attempt occurs. GPS trackers can pinpoint your vehicle's exact location and are often discreetly hidden in the car. Advanced tracking systems link to mobile apps, providing alerts when unauthorised movement or attempts to access the vehicle occur. Some systems allow remote shutdown of the car, adding an additional safety layer. Investing in such systems not only assists in recovery but also acts as a deterrent, as criminals tend to avoid vehicles with visible anti-theft stickers or signs.

Enhance Parking Security

Parking in a secure location is essential for reducing theft risks. When parking on the street, choose well-lit and populated areas; criminals prefer isolated and dark places to operate discreetly. At home, add layers of security by parking in a garage if possible or using surveillance equipment like motion-detecting lights and security cameras around your driveway. These visual deterrents, combined with the attention-grabbing effects of lights and cameras, make it challenging for thieves to operate unnoticed.

Stay Updated on Security Software

Many car manufacturers provide software updates to enhance vehicle security, especially for newer models with digital security features. Keeping in touch with your dealership or checking for updates can ensure your vehicle has the latest protective measures, as these updates may include patches that close potential security gaps. Regularly updating your car's software strengthens its defences against evolving threats, especially those targeting digital vulnerabilities.

By combining these methods, keyless car owners can significantly reduce theft risks. Embracing a layered security strategy, from physical barriers to digital protections, ensures that your vehicle is less susceptible to both opportunistic and organised crime attempts.
