Starting today you should start wrapping your key in aluminum foil.

⚠️ Downsides to Keep in Mind

While effective, foil is not a perfect solution:

• It can wear out over time and may need to be replaced regularly.
• It’s not the most stylish or convenient method.
• If not wrapped properly, it may not block the signal fully.

For longer-term use, consider buying a Faraday pouch or signal-blocking box, designed specifically for key fobs.

🧠 Bonus Tip:

If your key fob has a “sleep mode” or manual off switch (check your owner’s manual), use it when the key is not in use to stop it from transmitting altogether.

🚗 Final Thoughts

In a world where even your car key can be hacked, small actions like wrapping it in aluminum foil can offer surprising protection. It’s not high-tech or fancy, but it’s an easy first step toward keeping your vehicle safe.

So before you go to bed tonight or head into work tomorrow, grab that roll of foil in your kitchen drawer and give your key fob a quick wrap. It could save you thousands in theft and headaches.
