Experts warn that modern car keys constantly transmit signals, which thieves can intercept to unlock vehicles without touching the key.
A simple protection: wrap your key in aluminum foil. It blocks electromagnetic waves and prevents signal theft. Faraday bags work the same way.
Moshe Shlisel, CEO of GuardKnox Cyber Technologies, says these high-tech thefts are increasing, as tools to copy key signals are cheap and widely available. Until stronger protections are implemented, shielding your keys is a quick and easy way to stay safe.
