As keyless entry systems become more popular, they have also become a target for tech-savvy car thieves who exploit vulnerabilities in these systems. One common method is the “relay attack,” where thieves use signal amplifiers to capture and broadcast the key fob’s signal to the car, tricking it into unlocking and starting without needing the actual key. This article delves into how relay attacks work, why they’re so effective, and how systems like MoboKey can with the prevention of theft of keyless car.

What is a Relay Attack?

A relay attack allows thieves to unlock and start a car without the owner’s key fob. Here’s how it typically works:

  1. Signal Detection: Thieves use a signal repeater to detect the key fob’s signal. One thief will position themselves close to the key fob, usually near a door or window of the owner’s house. This device captures the fob’s signal, often through walls or windows.
  2. Signal Relay: The detected signal is then relayed to another device held by an accomplice near the car. By re-broadcasting the fob’s signal, this device convinces the car that the key is present.
  3. Entry and Theft: With the car now “thinking” that the key fob is nearby, it unlocks and allows the thieves to start the engine. Many cars have a range limit for the key fob, but thieves often only need to get the car around the block before transferring it to a secure location.

This method has become more common due to the rising prevalence of keyless entry and start systems in modern vehicles, especially those made before 2015. Cars within these earlier model years often have key fobs that continuously broadcast signals, making them vulnerable to these types of attacks.

Data on Keyless Car Theft in Canada and Beyond

In recent years, relay attacks have led to a surge in vehicle theft worldwide. According to data from the Insurance Bureau of Canada, car theft in Canada has increased by about 300% over the last decade, with many thefts involving vehicles with keyless entry systems. In the U.S., the National Insurance Crime Bureau has noted similar trends, particularly with high-value SUVs and luxury vehicles that utilize keyless entry and start features.

In response, car manufacturers have started incorporating security improvements, such as systems that automatically disable the fob after a few minutes of inactivity, which reduces the risk of signal hijacking. However, these systems are generally found only in vehicles produced after 2018 or require third-party accessories, leaving many older models vulnerable to relay attacks.

How MoboKey Can Help with Prevention of keyless cars:

While it may seem difficult to protect against relay attacks without upgrading to a newer vehicle, there are practical solutions that can help. MoboKey offers a range of features that can provide an additional layer of security:

  • Smart Access Control: MoboKey’s digital key system does not rely on traditional broadcasting key fobs. Instead, it uses Bluetooth connectivity from a smartphone app, making it more challenging for thieves to intercept signals.
  • Remote Locking and Alerts: If your car is moved without authorization, MoboKey provides immediate alerts, allowing you to react quickly.
  • No Continuous Broadcast: Since MoboKey relies on smartphone authorization rather than a constantly broadcasting key fob, it significantly reduces the likelihood of signal interception.

Additional Tips for Protecting Against Keyless Car Theft

To further protect against relay attacks, car owners can take a few simple steps:

  1. Use a Faraday Pouch: These pouches have materials that block RF signals. Therefore, prevent the key fob signals.
  2. Disable the Fob’s Signal: Some newer fobs can be set to “sleep mode” when not in use, or automatically turn off when they’re stationary.
  3. Store Your Key Fob Safely: Avoid placing your key fob near exterior doors or windows. The closer the fob is to the exterior, the easier it is for thieves to capture its signal.

Final Thoughts

As car theft techniques evolve, so should our approaches to car security. Keyless car theft prevention is a serious matter. With a rise in relay attacks targeting keyless entry systems, the need for secure and adaptable solutions like MoboKey has become more critical. Offering smart access, real-time alerts, and a Bluetooth-based system that minimizes broadcasting, MoboKey provides car owners with an extra layer of protection. As the technology in vehicles continues to advance, solutions like these ensure that security evolves alongside it, helping protect your investment against sophisticated theft methods.
