Mission Darkness Faraday Bag for Keyfobs (2-Pack) // RF Shielding Protective Case for Smart Always On Keys Fobs Transmitters Small Electronics Vehicle Security Anti-Hacking Block Signal Relay

Works great if your key is in the bag you can’t open your door or start your car it’s amazing I got one for each vehicle so when I get out of the car I lock it up and put my key in the bag and then in my pocket I also keep them in a bag at the house perfect size for carrying it in my pocket the price is great and the protection of my keys is great Thank You

👍🏽 I recommend this product for those of you who think ahead of you. It does work on stopping your key from transferring its signal to your car. It protects your key from being cloned. Highly recommended

This is military-grade. Blocks my car's keyfob signal from leaking out, even when I'm RIGHT NEXT TO THE CAR (my courtesy lights come on when the fob is out, so I KNOW when the car can detect the signal). After you reach your destination, the pouch fits in a pocket or purse. Keyfobs ALWAYS put out a faint signal when not blocked, even when NO buttons are being pushed; that's how people have had their cars stolen from their drive or their garage. The thieves grab that faint trickling-out-signal of the fob (from inside your house!) with a little relay box, electronically copy it (sometimes while standing out by the garage door), then point the box at the victim's car and DRIVE IT AWAY. The inside of the pouch is smooth fabric, coated with metallic signal-blocking material. It does wear off in places after a time, the keyfob being dragged in & out over and over thins the coating, and the signal will leak out. That's the convenience of the pouch being flexible tho (and a pouch with a zipper closure does NOT work; the signal leaks out between the closed zipper's teeth!). That's why there are 2 pouches in the pack; you'll have a spare. Another good option is an actual "Faraday box" that holds all your keyfobs when they're at home, but some people aren't able to designate a specific place for them inside the home. 🤷‍♀️

Tried with my car keys, no reception. Even comes with serial number and everything to know this is quality produced material.

These work! Forgot to leave my fob out while driving and the car said "Key not detected". Only thing i would like changed is the length of the folding flap. It's a bit too short to fold under the elastic and pops open easily. But for the price...it's pretty damned good.

Buyer Beware I bought a Mission Darkness cloth signal blocking Faraday Bag for my keyfob from Amazon, along with other products from their company & received this product on 10/31/25. The cloth signal blocking envelope only worked for 2 months, 19 days & now it won't block the signal, no matter how exactly I close it. I even put my keyfob in a plastic bag each time, before I put it in the Mission Darkness envelope to avoid any wear on the fabric. I was very careful to take care of the envelope. I am very disappointed in the quality of this product and how it stopped working after only 2 months, 19 days, which is unacceptable. I sent feedback to the Mission Darkness people and I hope they respond. I think they should replace the product as it did not last. This product doesn't appear to block the signal for very long or hold up to even the most careful use of it. If they correct this issue and the new product works for longer, I will update my review. Update: The vendor never got back to me or replaced the product despite me contacting them.

I got this for my Nissan Kicks key, and it works like a charm. Three weeks in, and the pouch is holding strong. It fits the fob with space to spare, giving plenty of room for a small key set without too much bulk in my pocket. I don't even need to close it—it's advisable to, yeah, but so far, the pouch blocks the signal by just sliding the keys in. You get peace of mind knowing your car is safe from relay attacks with Mission Darkness' Faraday bags.

These work so well. I use one for my car key and use the other for credit cards when I travel. I have tested the signal blocking by attempting to unlock my car while my fob is in the bag, and it is a no-go. Even when I am next to the car, my car is unable to sense the presence of the key, which is exactly what I am looking for. These are small enough to easily fit in my handbook, but large enough to hold all of my cards and keys. I highly recommend - especially for travel, visiting theme parks, fairs, or any other place where your information might get scanned!
