If you don’t take the necessary precautions, your car could be stolen… and they wouldn’t need your keys to do it. This is because modern car keys are constantly transmitting signals. Experts warn that thieves can buy an original car key and use it to replicate a specific vehicle’s access code.
How to prevent this from happening?
The easiest way is to wrap your keys in aluminum foil.
How do they do it?
Several cybersecurity experts agree that, while not ideal, it is very easy and inexpensive.
Another option is to purchase a Faraday bag online for a few dollars. It has the same insulating properties as aluminum foil and serves as a shield against the transfer of information that could be used in vehicle theft.
“How could I have stolen my old car with my cell phone, even after I sold it?”
“We’re talking about a form of communication through electromagnetic waves, like radio or television. Think of a song that’s constantly used between a radio and a lock that opens when it plays that song. If I know the song, I can open your lock.”
Moshe Shlisel, CEO of GuardKnox Cyber Technologies, a cybersecurity agency, explains it simply to BBC Mundo.
