Without the use of a Faraday key fob case or RFID key case, your wireless entry system (smart key) carelessly throws around the signal that contains your car's unique key code. If you do not place your key into a Faraday key fob case or key fob protector, then you car can be stolen without your knowledge.
Used to be “back in the day” that we old-timers had to do crazy labor intensive things like unlock our cars by sticking a physical key in the slot, or start our cars by inserting this same physical key into the ignition.
But now? Why, all we have to do is push a button and viola - instant access!
As already mentioned, though, these wireless remote keyless entry systems (that’s a mouthful) leave our vehicles vulnerable to car theft, and hackers and would-be car thieves have figured out a way to clone the signal from our wireless keys and open and start the ignition without us even knowing!
That’s why we’re all going to need to use a key fob guard or key fob protector moving forward as all of these car companies use them now and the technology isn’t going away anytime soon - nor does it sound like their security is of much priority to the car manufacturers.
As is typical these days, the consumer has to take matters into their own hands.
