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

Perfect size for key fob. Tested and works perfectly. Great thickness and value. Easy to use and especially like that it has no velcro and just folds over.

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. 🤷‍♀️

These do what they're supposed to. No signals leak from these pouches when your fob is in it. In fact, sometimes I forget the fob is in this and I expect the car to unlock for me as I approach. It doesn't. I find myself a little annoyed that I have to dig in my purse and take the fob out of this case, then I remember that's exactly the reason I got these.These are a bit too large for typical sizes of fobs though. We have BMW and Porsche fobs and these are quite oversized for either of these. That excess material makes it difficult to just slip in a pocket or purse.I turned them inside out, sewed then cut about an inch off the bottom and it's more compact and manageable now. I can still even fit a few credit cards in this if I want to. My phone (Pixel 7 Pro) is too wide to fit in here regardless of if I cut it down or not.There's an elastic band that you're supposed to tuck the top flap into. We find that we don't utilize the elastic at all. If the fob is fully in the pouch, the tucked in flap seems only as a safety so the fob doesn't fall out. I use a small lanyard and secured the fob to the pouch instead.It does it's job well and that's what's important.

I've been on the hunt for something to keep my car's key fob from chatting with every rogue signal in the city, and let me tell you, the Mission Darkness Faraday Car Fob Bag is like a secret service agent for my keys.First off, the design is slick - it looks like something James Bond would use. The material feels like it could survive a zombie apocalypse, which is reassuring because if there's one thing I trust less than my ability to remember where I parked, it's the security of my car's key fob signal.Now, about functionality - this bag blocks signals like a bouncer at an exclusive club. My fob goes in, and suddenly, it's like it's in a signal-proof safe. No more worrying about relay attacks or my car deciding to unlock itself because it thinks it's in a sci-fi movie.The size is perfect; it's not so big that I look like I'm carrying around a lunchbox for my keys, but not so small that I'm fumbling around like I'm trying to find a contact lens in a haystack. Plus, it's got this little loop for attaching to my keyring, which is a nice touch.Durability? This thing could probably survive being run over by my car, which is good because I've been known to drop my keys more often than I drop hints.The only gripe? Well, it's not really a gripe, but if it had a little magnet or something to keep it closed, that'd be the cherry on top. But hey, for what it does, I'm not complaining.In summary, if you're paranoid about your car's security or just want to keep your key fob's signals to itself, the Mission Darkness Faraday Bag is your new best friend. It's like putting your keys into a mini Faraday cage - secure, stylish, and it makes you feel like you're in on some high-tech secret.Rating: 4.5 out of 5 stars. Because, let's face it, nothing's perfect, but this comes pretty darn close for keeping my car's keys on lockdown.
