Samurai Japan Relay Attack Prevention Key Case : Radio wave blocking technology
"Just pop your key in, and it's shielded." That's the simple promise of the Fogman Relay Attack Prevention Key Case. This little gadget tackles a modern menace: relay attacks, where thieves amplify your key fob's signal to unlock and start your car from a distance—no breaking in required. By blocking those sneaky radio waves, it keeps your vehicle secure even when your key is chilling on a table inside your house. Perfect for anyone with a keyless entry system, it's dead easy to use. Slip your key into the case, and it does the rest, cutting off external signals automatically. Beyond security, it offers peace of mind for daily life, whether you're parked on a busy street or overnight in your driveway. Built tough with durable materials, the set includes two cases—handy for multiple keys or sharing with the family. It's a smart, no-fuss upgrade to your anti-theft toolkit.
