Modern car thieves don't need to hotwire—they hack key fob signals through walls using $30 gadgets. Foil to the rescue! Crumple your keys into a tin-foil "burrito" (shiny side in!) to create a Faraday cage. This blocks radio waves like a superhero cloak, making your car invisible to digital prowlers.
Pro tip: Test it by locking the car with foil-wrapped keys—if it doesn't work, wrap tighter!
For all-day protection, stash keys in an old mint tin lined with foil. Bonus: This also stops pocket-dialing your trunk open at the mall. Note: Thick foil works best, but even a Chipotle wrapper buys you time. Just don't forget to unwrap before driving—no foil-covered steering wheel heroes!
