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

The bags work with hiding the signal, worth the money spent. Ordered two more and have the box as well.

When I first opened this package I thought “these are big”. Then I jammed my larger fob into the case - but not in the fully protected part and thought “oh it needs to be large”. But the key still worked. When I replaced the smaller fob and put in the right compartment, everything was as expected. My fob did not open the doors or start the car.The case has both a key ring on the outside as well the outside and is a bit large for all day use but great for storing key fob once parked.In sum, great if the key fob fits in but not if you have an oversized fob or case.

Good quality

I don't have a way of testing these, so my review is simply on the quality of the product. They are very well made. I got this because a police officer was admiring my Dodge Charger Scat Pack and asked if I kept my key fob in a Faraday type bag, because he told me my car was one of the most stolen cars in the metro Atlanta area. He said a theft will target a car like mine, wait until the owner parks around a big store or mall and then walk by you as you are going in and use a reader to read the signal your key fob uses and then walk back out, open your car and drive off. These are a little bigger than I wished, but nice quality.

This product is accurately described in the listing and exactly what I expected.

These bags need to be completely closed in order to block off any signal from the key fob. If you leave the flap open, some of the signal can get out and still reach your vehicle. However, if you're within 2-3 feet of the car, the faraday bag might not work as well for blocking signals.

These faraday bags work well. They are a little smaller than what we had before, but they still fit our MB key fob.That’s a good price for two.Thank you.

Works as advertised! It actually has 2 pouches...the outside one does not block RFID but the larger inside one ABSOLUTELY does! Just what I needed. Came with 2 bags that both have an attachment for a keychain. Like these a lot...big thumbs up!
