The Risks of Relay Attacks and Keyless Entry Systems

In recent years, advancements in technology have made our lives more convenient in many ways. One such advancement is the introduction of keyless entry systems in cars, which allow us to unlock and start our vehicles with the push of a button. However, with every convenience comes a potential risk, and keyless entry systems are no exception.

The Dangers of Relay Attacks

Relay attacks have become a growing problem for car owners around the world. These attacks intercept the signal between the key fob and the vehicle’s entry system, allowing unauthorized access to the vehicle. Once inside, they can easily steal the car or its contents.

Relay attack devices such as keyless entry repeaters and signal jammers are readily available in the market. These devices can be used to extend the range of the original key fob’s signal from the car, allowing the car to be unlocked and started even if the owner’s key fob is inside the house. Jammers are used in tandem with keyless repeaters in order to interrupt all possible connections of the car with the outside world, with GPS or Glonass satellites, with the help of which the location of the car is tracked; telephone sensors, the Internet and others are also blocked, depending on the intended protection system of the car . In some cases, a shielded fabric is used that completely covers the car, thereby blocking any possible radio waves.

The Importance of Car Key Emulators and Detectors

While relay attacks pose a significant threat to car owners, there are steps that can be taken to protect against them. Car key emulators and detectors are two such tools that can help mitigate the risks associated with keyless entry systems.

Car key emulators are devices that mimic the signal of a key fob, tricking the car’s entry system into thinking that the owner’s key fob is present. This can prevent relay attacks by confusing the criminals’ devices and rendering them ineffective.

On the other hand, car key detectors are designed to alert the owner if a relay attack is taking place. These devices can detect the presence of relay attack devices and notify the owner through an alarm or a smartphone app. This allows the owner to take immediate action and prevent their car from being stolen.

Protecting Your Car and Yourself

While it is important to be aware of the risks associated with keyless entry systems and relay attacks, it is also crucial to take proactive measures to protect yourself and your vehicle. Here are some tips:

• Keep your key fob in a signal-blocking pouch or a Faraday bag when not in use. This will prevent criminals from intercepting its signal.
• Consider installing a steering wheel lock or a car alarm system to deter thieves.
• Regularly check for software updates for your car’s keyless entry system, as manufacturers often release patches to address security vulnerabilities.
• Be cautious of where you park your car, especially in high-crime areas.
• If you suspect that your car has been compromised, contact the authorities immediately and report the incident.

By taking these precautions and staying informed about the latest security measures, you can minimize the risks associated with keyless entry systems and relay attacks. Remember, it is always better to be proactive and protect yourself before becoming a victim.
