Upgraded Fireproof Faraday Bag for Key Fob (2 Pack), Hodufy Premium Faraday Cage Protector - Car RFID Signal Blocking, Anti-Theft Pouch, Anti-Hacking Case Blocker (type-01)

Initially could not get these to work at all. The seller has now clarified that the key must be located inside the light coloured ( gold?) liner for the signal blocking to work. Unfortunately, there are no instructions supplied and it's just as easy to slip the key in the wrong side of the liner - which is what I initially did. Now, properly informed, these working brilliantly and I'd highly recommend them.

Perfect size nice style. Key straight in with about 4 other keys on so didn't have to mess about taking other off. Straight over to car not a single bit of signal leaving that bag. Instant. Wonderful little safety product. Thank you guys Brand new car and it works perfect for it.

Was uncertain when I brought but it works well I signal from my key fob when insideSo pleased I brought a second one

Gold coloured pocket inside is reasonably sized - able to get my KESSY fob inside together with its key ring and a couple of keys attached, and fold the flap down. Does what it says on the tin: car refuses to respond even when the pouch is placed right next to the doors or start button with the fob inside it.

Works fine, i have a hefty set of keys on my car key, key ring, and all fitted nicely into the gold part of the pouch. Pressed the button through the pouch and completely blocks any signal and the bag also waterproof and fireproof. Definately a must have item for keyless starting cars.
