2 Pcs Faraday Bag for Car Keys, RFID Signal Blocking Pouch, Anti-Theft Key Fob Protector, Cell Phone Signal Blocker Case, Car Key Fob Cage (Small)

This does EXACTLY what it states!!!!

it works, but after a few months, it stops working

The bag looks like it's well-made, but it doesn't work as it should. I can still unlock, open, and start my car without taking it out of the bag. I will be asking for a refund

As soon as it arrives I tried it and it worked perfectly fine. I definitely recommend it. In order for it to work you need to put the key on the second pocket with the key ring, you won’t be able to start the car at all. It really does the job . The front first pocket allow you to start the car and drive. It’s worth it and the price is reasonable and get the smaller size they run big enough for the keys.

My key does not fit well into this pouch but it's because I have my key on a ring with other keys. It works fine.

Came fine. It looks like it works… there is no way to test it really, but the material and assembly look legit, so fingers crossed.

Today your keyfob can be read by thieves. Theses keyfob pouches will block the keyfob from transmitting signals.. I proved it by putting the keyfob in the pouch, in the car. It wouldn't start. As long as the keyfob is in the pouch it's theft proof while you do your errands. Frank S.

Works but there is a caution about using it: perhaps due to inadequate adhesive the layers of the pouch are delaminated. If you have such a pouch, you have to put the fob inside the inner, thin pale material bag that you will find inside the thick black material bag. Otherwise the pouch will fail to block radio signals as some reviewers have complained. Once you put the fob within all the bags-within-bags of the delaminated faraday bag it works fine and blocks RFID quite well.

Buen producto; un poco grande
