2 Pack Faraday Bags Key Fob Protector, 3.15'' X 5.0'' Faraday Cage Protector, Car RFID Signal Blocking Key Fob Protector, Carbon Fiber Security Anti-Theft Car Key Pouch, Anti-Hacking Case Blocker

It doesn't work! My car doors open & my car starts with the key fob in the faraday sleeve!

This Faraday pouch successfully blocked the signal from my 2024 Toyota key fob. When sitting in the vehicle with the key fob in the pouch and pressing the start button, the display said "Key fob not detected". The size of this pouch is a bit of a tight fit over my key fob with a leather cover, and it is too small to close the flap when both the key fob and an Apple Air Tag attached to the key fob with a small ring are pushed into the pouch. But even without the pouch's flap closing, the key fob signal was blocked.

The media could not be loaded. I was skeptical about RFID-blocking bags when I first heard about them. Can they really protect my credit card and car key fob? When I saw these two bags offered for review, I decided to give them a shot. At first glance, nothing seemed special about them. I did notice two pouches—front and rear—instead of one. The rear pouch even has a keychain. I wasn't sure about the difference between the pouches; the rear one didn't look like it should hold anything.Naturally, I put my car key fob in the front pouch, as shown in the picture. When I got close to the car, the side mirror light turned on, and I could open the door by pulling the handle. I thought this was a joke. Should I even try the second bag in case the first one was defective? I decided to put the key fob in the rear pouch. To my surprise, the side mirror light didn't come on when I approached, and the door wouldn't open until I took the key fob out of the bag. It really works, except you shouldn't put anything you want to protect in the front pouch, which likely leaks signals.I don't know how they test these bags or why they show the picture with the key fob in the front pouch, but if you want to protect your RFID devices or cards, put them in the rear pouch. It really works. I take out one star here because their ad is not accurate.
