Why do you need the Faraday Bag?
Modern keyless fobs carry identification chips that pick up radio signals sent out by their car. The vehicle recognizes the fob when it's in range and unlocks the doors. Keyless ignition systems work in the same way - enabling cars to start when the key fob is detected in the cabin. Criminals can exploit this via a wireless relay attack. Using a radio frequency relay booster, it's possible to pick up and then transmit a key fob signal to trick the car into thinking a fob is present. This enables entry and theft from the cabin or boot - and, in the case of keyless ignition systems, theft of the vehicle itself. Thanks to its 100% signal jamming capability.

Bought the small size of this bag and it perfectly fits the key fob for my 2024 Subaru Crosstrek. I really like the key ring INSIDE the bag to attach to the fob AND the heavy duty carabiner on the outside to attach to my purse or the belt loop of my jeans if I’m not carrying a purse. I also tested leaving the fob in the bag and then tried to start my car ~ but the car could “not detect†the key when in the bag ~ so it definitely works ~ I can only start the car if the fob is out of the bag.

I got the medium sized bag for my 2024 Toyota Tundra key fob. I like that it comes in a 2 pack so I can put the spare key in the other bag. I tested opening the door with the key in and out of the bag. The key will not work when it is in the bag. Does what it is supposed to do, highly recommended.

Pouch is about the length of my iphone pro & a bit wider. Top end is a flap to fold over and close the pouch, locking with a velcro strip. Our fobs are large and just fit the pouch. There is a short chain and loop lock attached inside the pouch to attach the fob to. Even next to the car, no signal detected. Fob has to emerge > half way for car to sense its presence, so it meets our protection requirements. On the back is another loop retainer and a small caraabiner, so can attach to purse or belt loop. No extra room for wallet, credit cards, etc to speak of, though would have been nice to have to protect credit cards.

One thing to note: very small as it needs to be. So if you have many keys or items on your key ring, it won’t fit

For the past month since purchasing, I’ve used this product every time I drive somewhere. Nissan fob fits perfect inside the bag. It took me the first couple weeks to remember to take my fob out when my door wouldn’t unlock. I have the pouch loop attached to a carabiner type belt clip to attach to my pant belt loop. I like the addition of a chain. I attached my fob on the chain and it allows you to take the key in and out of the pouch while staying on the chain so you don’t lose it. Once the fob is out it can dangle down or can be put through the loop of the pouch. The pouch is on the slightly bulky side, but it’s as small as it can be to fit the fob into. It definitely works to block the signal, even when I’ve opened the top the signal is stopped until I take the fob out. You could spend 8 times the money for a hard case design somewhere else, but it be would be only slightly smaller, which makes this a great value. No signs of wear so far in the month or so I’ve been using it. I bought more for the peace of mind when my dogs are in the car when running errands. But put the keys in the bag when home. Very satisfied with product.

OMG, I received this and used it today, and it really works. I was in my car and tryed to start my car with the key fob in the case and my car would not start and it said...no key fob detected. I took it out of the pouch then my car started. I would tell you to buy this and you'll see it works.

I got 2 styles of pouches. I preferred this one as there was a ring for extra keys on back.

Love these as they are small enough to fit in a small bag which is great. Really well made too.

Je recommande ces étuis efficaces solides pratiques. J ai testé. Effectivement le véhicule ne peut pas s ouvrir quand la clef est dans sa pochette.
