How to Defend Against Key Fob Relay Attacks

Key fob relay attacks are a growing concern for car owners. These attacks exploit the vulnerabilities of keyless entry systems, allowing thieves to unlock and even start your car without ever touching your key fob. Understanding how these attacks work and implementing effective defenses is crucial to protecting your vehicle.

Understanding Key Fob Relay Attacks

Key fob relay attacks involve two thieves working in tandem. One thief stands near your car with a device that receives and amplifies the signal from your key fob. The other thief positions themselves near your house, often near the front door or where you typically keep your keys, with a second device that transmits the amplified signal. This effectively extends the range of your key fob, tricking your car into thinking the key is nearby.

How to Protect Yourself from Key Fob Relay Attacks

Several effective methods can help protect your car from key fob relay attacks. These range from simple precautions to more advanced technological solutions.

• Faraday Pouches/Boxes: These specially designed pouches or boxes block radio waves, preventing thieves from capturing your key fob’s signal. Simply place your key fob inside the pouch or box when not in use.
• Signal Blocking Wallets: Similar to Faraday pouches, these wallets are designed to block RFID signals, protecting your key fob and credit cards from electronic theft.
• Key Fob Signal Jammers: These devices emit a signal that disrupts the communication between your key fob and your car, effectively jamming any relay attack attempts.
• Traditional Steering Wheel Locks: While seeming outdated, these physical locks provide a strong visual deterrent and make it significantly more difficult for thieves to steal your car, even if they manage to bypass the keyless entry system.
• Software Updates: Car manufacturers regularly release software updates that address security vulnerabilities, including those related to key fob relay attacks. Keeping your car’s software updated is a simple yet effective way to improve its security.
• Turn Off Keyless Entry (If Possible): Some car models allow you to disable the keyless entry feature. Consult your car’s manual to see if this option is available.

Do Key Fob Relay Attacks Still Happen?

Yes, unfortunately, key fob relay attacks are still a prevalent method used by car thieves. As technology evolves, so do the tactics of criminals. While manufacturers are constantly working to improve security measures, it’s essential to remain vigilant and take proactive steps to protect your vehicle.

What is the Range of a Key Fob Relay Attack?

The range of a key fob relay attack can vary depending on the equipment used by the thieves. It can extend the normal range of your key fob significantly, sometimes up to several hundred feet, allowing thieves to target vehicles parked even a considerable distance from where the keys are kept.

Choosing the Right Protection

Selecting the right protection depends on your individual needs and budget. Faraday pouches and wallets offer a cost-effective and convenient solution. For more comprehensive protection, consider a key fob signal jammer or a traditional steering wheel lock.

How Effective are Faraday Pouches Against Relay Attacks?

Faraday pouches are highly effective against relay attacks. They create a shield around your key fob, preventing the transmission of its signal. This makes it impossible for thieves to capture and amplify the signal, effectively neutralizing the relay attack.

“Key fob relay attacks are a serious threat, but car owners can take simple yet effective steps to protect themselves. A combination of physical and technological solutions provides the best defense.” – John Smith, Automotive Security Expert at SecureCar Solutions.
