Modern car keys broadcast constantly. Thieves catch that signal from outside your house, relay it to your car, and drive off — no broken window, no alarm. Drop your key fob in this Faraday pouch and the signal stops dead.
Blocks the relay attack that opens keyless cars
Also shields phones, hotel key cards and contactless cards from tracking and skimming
Two pouches — one for the car key, one for your phone
Slim enough for a bag or glovebox. Ships free from the US.
