Wrap your car key fob in foil. Here's Why.


DETROIT – Given that the best way to store your car keys at night is by putting them in a coffee can, what's an ex-FBI agent's advice to protect cars from theft during the day?

Wrap car fobs in aluminum foil.

“Although it's not ideal, it is the most inexpensive way,” said Holly Hubert, a cybersecurity expert who retired in 2017 from the FBI in Buffalo, New York. “The cyber threat is so dynamic and ever changing, it’s hard for consumers to keep up.”

Now, as CEO of GlobalSecurityIQ, she suggests clients go online and spend a few dollars and buy what’s called a Faraday bag to shield the fob signal from potential theft. Imagine a traditional sandwich bag made of foil instead of plastic.

Thing is, the car is always waiting for the fob signal. Thieves can buy legitimate devices that amplify the fob signal sitting unprotected in a purse, a pocket, on a counter at home or even just copy the code to access the vehicle. Read full story about wrapping a key fob in foil.
