MONOJOYFaraday Bags Key Fob Protector: Faraday Bag Car Key Fob Signal Blocker RFID Key Fob Protector Faraday Key Fob

I am very happy that I purchased them. And they do work!

We are out a lot with our car parked in public places. With a rash of car thefts done by opening cars remotely, our friend suggested a faraday bag to make sure our car wouldn't be stolen. The bag really works. If I don't remember to take my car fob out of the bag, or at least leave the top of the bag totally open with the fob protruding, the car will not unlock. If the fob is sealed in, the car won't unlock even if I'm standing next to it!! I'm less worried about the car being stolen remotely with the faraday bag and this one seems to be sturdy.

Smart keys that open doors when every you're near can be a risk. This key bag blocks all testable communication between the car and smart keys. The car locks as soon as you put it in the bag, not 20 feet later! A bit bulky but easily slides into any pocket. After learning all of the safety features of the Honda, the RFI bag is needed less. It's only a matter of time that keyless devices will be scanned by pirates for their codes and your car will be gone when you return. Yes, I'm a parnoid who has suffered losses to hackers and such.

I got this to combat the possibility of someone breaking into or starting my car with a key fob RFID booster / repeater. My car is parked directly under my master bedroom and the distance from my nightstand to the driver’s seat maybe eight to ten feet.The bag is big enough for my car’s key fob (which itself is in a protective silicone cover) and the physical keys on my key ring, which is essential. Many similar bags are barely big enough for a key fob.The bag blocks the RFID signal completely. Even when the key fob inside the bag is immediately next to the RFID antenna of my car’s steering column (the emergency starting location where it can normally pick up the signal of a fob with a dead battery), the car can’t detect the signal and displays a message that there is no key in range.

Small package, huge protection! Bought 4 (don't forget the spare set of keys at home - thieves can access your vehicle if the keys are available within proximity of your car (hall table, side table, key rack, etc.), and take off with your car in the middle of the night) Put the spare sets in one pouch and put it away. When you're home, put your key fob (or all your keys) in the pouch to block any RFID attacks. I went out to my car last week and knowing that all I had to do (normally) was touch the door handle, I did and the door did not unlock! The fob was in the pouch - so I KNOW these work - first hand experience! Get them for each vehicle you use a fob to open the vehicle, and particularly if you have keyless ignition!!!!

I tried to open my car door and it wouldn’t until I realized that the key fob was in the pouch. So if you had any doubts it works!

I liked this case for my FOB. It works great. However, over time the RF blocking stops working. Guessing the thin layer they use just wears out after a few months.

We have the smart key with encrypted technology for our brand new 2022 SUV but my husband wanted these to prevent theft. I chose these for the size so it fits easily into his pocket. If the fob is in the case, we can't lock, unlock or start the vehicle. I admit it's a hassle to take the fob out because I wanted to be hands free when opening the door and starting the engine - that's the main reason the have a smart key; but it does give peace of mind knowing the signal is blocked when the fob is in the case.Update: I keep this pouch in my purse in a separate zippered pocket. The PU leather is already flaking off near the top where it folds down. I have handled this pouch less than a dozen times in the 9 days since it was delivered. Extremely disappointed.Update to my update: Excellent customer service from the seller! I contacted them though Amazon and they answered my email very promptly. They graciously offered to send a replacement. I changed my rating to 5 stars.

Works great. I can strand right next to my truck with the fob in this pouch and still won't be able to access the locks. 👍

The pouch is easy to put in your pocket, the fob is attached to a hook on the pouch so they are always together. I stood right beside my car and I could not unlock the doors or start the engine. My car now feels safe.

En efecto son dos bolsas, relativamente son de tamaño chico y solo cabe la llave del carro, totalmente funcional y hermética para que no te clonen la señal. Buen material y acabado. Producto recomendable.

Produit très efficace. A chaque fois que j'y insère mes clés je vérifie manuellement que les portes ne s'ouvrent pas et tel est le cas. Donc, rempli parfaitement son rôle.

Funciona perfectamente con unas llaves de Seat Ateca que es para lo que las quería, ni al lado de la cerradura detecta dichas llaves dentro del estuche..
