These are really good and they work. They were recommended by the Police in our area as there had been a lot of car thefts recently. I keep one in my hand bag for when I’m out and about and one indoors so my car key signal cannot be picked up by anyone outside my house. You really do have to take it out of the pouch for the car key to open the car door even if holding pouch in your hand. I thoroughly recommend these Faraday Pouches.
