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. 🤷‍♀️

It works. I tested it by putting the pouch on my belt, and putting the key fob in the pouch. I tried to open my car doors, which automatically open when the fob is in proximity, and they would not open. I take the key fob out of the pouch and put it in my pocket, and the doors unlock automatically.With my other cars, I always liked to pull the door handle to confirm they were locked, but could not with this car. Now, I can go back to that routine.

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.

UPDATE March 2024: After 17 months of use, the RF protection is no longer present in this faraday pouch. It’s clear from other users of this and similar products that these pouches have a lifespan and are not designed to last in perpetuity. The only problem is there is no way to determine the useful life and the manufacturer doesn’t provide any guidance on lifecycle either. I suspect the failure point is folding the fabric multiple times per day. You basically have to test the pouch every so often to see if it still works. I’m not psyched about the possibility of a thief catching a signal between failure and the next test. Yet I’m not sure there are any other options. I have yet to see a faraday pouch on the market with a 100% success rate forever, and no manufacturer is willing to admit their pouch has limited lifespan.So, I’m planning on replacing these every six months. This particular bag is inexpensive enough to replace at that interval, and I know my current set lasted that long. Plus it’s generally well made otherwise. (Still haven’t gotten additional colors or a way to tell multiple bags apart other than putting tape on them, which looks kind of terrible.)Normally I’m not a fan of Amazon’s “subscribe and save” service, but if anything deserves it, it’s this product. Yet, it’s not even offered, which is a pity.ORIGINAL REVIEW: Works as advertised and intended. Feels like very nice construction and materials. The nylon outer fabric is sturdy and feels like a nice woven backpack material. The elastic band is fine, but I’m betting that’s the eventual failure point.I didn’t realize this until I got the package, but there are 2 bags to an order, not one. Makes these a good bargain.Deceptively simple fold-over construction. Probably not the bag to use while running. But should be fine otherwise.I have two big issues with the bag: 1) Needs to come in other colors, have a place to label, or otherwise natively tell these bags apart. I have 4 in the house and have to go buy some sort of charm or colored tape to tell which keys are in which bag. 2) The opening of the bag is slightly smaller than rest of bag and expands more past the opening. Limits what can fit past the opening. Can’t get more keys than the actual fob past the opening even though the bag once key is in has plenty of room. Would really like to get my whole ring of keys in the bag rather than having to keep the fob separate from other keys.Would probably buy again, but look hard at competitors with colors.

IT WORKS! I have returned 2 “fob protectors” from other companies due to them not working. Both key fob protectors are excellent. They are very well made and fit the larger key fob types. Thank you. I now feel much better about taking my vehicle out and leaving it in a public parking lot. I highly recommend.
