Review on 2 Pack Faraday Bag for Key Fob - TICONN Car RFID Signal Blocking Protector, Carbon Fiber Texture, Anti-Theft Pouch, Anti-Hacking Case Blocker by Peter Sullivan

Works as intended. Those complaining that it doesn't work are probably putting it in the front pocket, like I did at first, rather than all the way to the back. I buy more for family members with keyless entry. It doesn't hurt to have a foot pedal lock for added security. UPDATE: After a few weeks I found that it stopped working. BUT the reason was that I had my 2 most used keys clipped when they were in my back pocket. It was important. Perhaps the keys played the role of an antenna when connected to the key fob? I do not know. UPDATE 7/22/19: It just doesn't work anymore. Even if I put it in my back pocket. My guess is that the stuff they use to block RF IDs degrades over time.
