You’re stepping out of a restaurant, key fob in hand, ready to head home after a delicious meal. You press the unlock button, but nothing happens. You try again, and again, but your car remains unresponsive. Unbeknownst to you, tech-savvy thieves have just driven off with your prized vehicle, all thanks to a key fob relay attack.
Key fob relay attacks, also known as relay theft or key fob hacking, have become increasingly common, leaving car owners vulnerable to theft. This type of attack exploits the wireless signals emitted by key fobs to unlock and start your car, even from a distance.
How Key Fob Relay Attacks Work
Imagine two criminals working in tandem. One stands near your house, potentially near your front door where you typically keep your key fob. They have a device that captures the radio waves emitted by your key fob. This device then relays those signals to another device held by their accomplice, who is standing near your car. The second device essentially tricks your car into thinking the actual key fob is present, allowing them to unlock the doors and drive away.
This type of attack is particularly concerning because it’s often silent and leaves no signs of forced entry, making it difficult to detect and even more challenging to prove to insurance companies.
Effective Ways to Prevent Key Fob Relay Attacks
The good news is that there are several steps you can take to protect yourself and your vehicle from falling victim to this sophisticated theft technique.
1. Invest in a Faraday Pouch or Box
“Think of a Faraday pouch like a digital safe for your key fob,” says automotive security expert, James Walker. “It essentially blocks the radio waves that your key fob emits, preventing thieves from amplifying and relaying the signal.”
These pouches and boxes are lined with a material that blocks electromagnetic fields, creating a secure barrier around your key fob. When not in use, simply store your key fob in the Faraday pouch or box.
2. Turn Off Keyless Entry When Not in Use
While convenient, keyless entry systems are the primary target of relay attacks. Most modern cars allow you to disable this feature through the vehicle’s infotainment system. Consult your car’s manual for specific instructions.
3. Consider Traditional Security Measures
While technology is constantly evolving, sometimes the simplest solutions are the most effective.
- Steering Wheel Locks: These physical deterrents may seem archaic, but they provide a visual reminder to would-be thieves that your car is a harder target.
- Wheel Clamps: For added security, especially if you park your car in a vulnerable location, a wheel clamp can be a powerful theft deterrent.
4. Update Your Car’s Software
Car manufacturers are aware of the vulnerability of keyless entry systems and regularly release software updates to patch security flaws. Make it a habit to check for updates and install them promptly.
5. Be Mindful of Where You Keep Your Key Fob
Avoid leaving your key fob in close proximity to doors and windows where criminals could easily capture the signal. Be particularly cautious if you live in an apartment building or densely populated area.
Conclusion
Key fob relay attacks are a growing concern, but by implementing these preventative measures, you can significantly reduce the risk of becoming a victim. Remember, being proactive about your car’s security can save you time, money, and the stress of dealing with the aftermath of theft.
