🔑 The Problem: Your Key Is Always Talking
Modern car keys aren’t just plastic and metal—they’re mini computers that constantly send out a signal to your car.
That’s what makes keyless entry so convenient.
But here’s the catch:
Thieves can hijack that signal, clone your key, and unlock or even start your car—without ever touching it.
🕵️♂️ How Do They Do It?
With easily available tools, hackers can “listen in” on the wireless communication between your key and your vehicle.
It’s like they’re recording a secret song—and once they know the tune, they can play it anytime to access your car.
🛡 The Easy Fix: Aluminum Foil
It may sound like something from a spy movie, but wrapping your car key in aluminum foil really works.
Why? Because foil blocks electromagnetic signals.
It turns your key into a DIY Faraday cage, protecting it from wireless theft.
🚗 Want a Sleeker Solution?
If wrapping your keys every day feels like a hassle, consider a Faraday bag or pouch.
It’s specifically made to block signals and comes in stylish, compact designs perfect for daily use.
🧠 Expert Insight
Moshe Shlisel, a cybersecurity expert and former Israeli Air Force defense engineer, puts it simply:
“It’s like a song that plays between a key and a car. If someone knows that song, they can open your lock.”
Aluminum foil or a Faraday pouch acts like earplugs for your key—no signal, no theft.
⚠️ The Risk Is Real—and Growing
These signal-stealing devices are cheap, easy to find online, and come with YouTube tutorials.
Even as automakers develop better protections, you’re still vulnerable right now.
✅ The Takeaway:
Wrap your key in foil or store it in a Faraday bag.
It’s simple, affordable, and could stop your car from disappearing right out of your driveway.
