Wrapping your vehicle keys in aluminum foil may sound peculiar, but recent advice from security professionals and law enforcement agencies supports this practice. This essay explores the rationale behind this simple trick’s growing popularity and its role in protecting your car from theft.
Understanding the Risk
The technology embedded in modern car keys is at the heart of this recommendation. Many contemporary keys use keyless entry systems employing radio frequency identification (RFID) signals for unlocking and starting vehicles. However, savvy criminals have found ways to exploit these conveniences. By using a device called a relay amplifier, thieves can intercept the signal from your key fob even while it’s inside your home.
The Role of Aluminum Foil
Placing your key fob between two layers of aluminum foil blocks the radio waves it emits. This prevents unauthorized devices from picking up and amplifying these signals to gain access to your vehicle. This simple step effectively thwarts attempts by thieves to exploit your key fob’s signal.
