🔑 Why You Should Wrap Your Car Keys in Aluminum Foil — It’s Not Just a Weird Trick!

It might sound like something your tech-paranoid uncle would suggest, but wrapping your car keys in aluminum foil is more than just a quirky DIY — it’s actually a simple, low-tech way to protect yourself from high-tech car theft.

If you drive a car with keyless entry or a push-start ignition, this is one trick you’ll want to pay attention to.

🚘 The Problem: “Relay Theft” Is on the Rise

Modern cars often use a key fob that sends out a wireless signal to unlock your vehicle when you’re nearby. While convenient, this technology also opens the door (literally) to a method called relay theft.

Here’s how it works:

• Thieves use a signal amplifier to pick up the key fob’s signal from inside your home (yes, even through walls).
• A second device near your car relays that signal to unlock and even start the engine.
• The whole process takes seconds — and you might not even realize your car is gone until hours later.

🧠 The Simple Fix: Aluminum Foil

Aluminum foil blocks radio frequency (RF) signals. Wrapping your key fob in foil acts like a mini Faraday cage, disrupting the signal and preventing thieves from hijacking it.

It’s:
✅ Inexpensive
✅ Easy
✅ Surprisingly effective
