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

I've been using the pouch for a month now since I bought my new car and this works perfectly as intended and gives me peace of mind, every time I lock my car. The bag is very durable and has enough space to carry my keyfob and attached keyring as well. A great little accessory to keep your keyfob secure!

Having had my 18 month old Mercedes stolen due to suspect key cloning on the key less entry vehicle I looked at ways to prevent this occurring again. I can confirm that the Mission Darkness Bag works exactly has described, I tested the bag by opening the door of my new BMW sitting inside putting the key fob into the bag and attempting to start the engine, the response to this was key not detected and the engine would not start. In future when I am not driving the vehicle I will be leaving the key fob inside of the bag with the reassurance that it cannot be cloned, this is a very good well made and classy looking product that I can highly recommend.

As far as products go I can honestly say that the quality of the product on offer was very good. It was small enough for the job in hand i.e. car keys, and fit into a pocket or bag nicely. However, when a product appears to work at first and then fails after a few short weeks then there is something sorely amiss in its design. I bought this to protect a fairly substantial investment but it ended up being just as effective as a crisp packet!In theory a great idea but in practice not nearly worth the premium price it costs. I’m now waiting on a replacement product from another manufacturer that is 20% of the price of this one but has been highly recommended by other owners. Fingers crossed second time around.

Does a good job at shielding the key at present. Lets hope it lasts. Size and belt loops are convenient too. Review update 7 months on. Bag has now stopped working.

I purchased theses following a news item on our local news about how easy it is to steal vehicles with key-less ignition using readily available items of kit. our new ford has key-less ignition which is very convenient but i was unaware of how easy it was to steal them using key cloning methods.i googled the problem and came up with Faraday bags. found these ones and ordered two. I tested one to see if it works, put the key-fob in the bag and closed it as the instructions, stood by the car and pressed the button on the door handle to open the car, nothing happens the car remained locked, the bag had shielded the key from the car so it could not detect it. took the key from the bag and the car opened as normal, it works. i think the cost of this bag is well worth it if it protects our new car which cost thousands. The car keys will be kept in this bag from no to prevent them being cloned .The bags them selves are well made from quality materials, you can fold it up and attach it to your keys for every day use, a loop is provided or you can attach it to your belt, it closes by folding the top over and under an elastic strip, better and easier to use than Velcro.these will provide good protection and security from cloning car thieves, i also use a good old fashioned steering lock to deter possible tea leaves,

Works, straight out of the packet. Car doesn't see key when it's in the bag in the car (nor when it's wrapped in tinfoil for that matter).But better made and more usable than tinfoil - and I liked the name!Looks good - a snug fit for two large (4 button) car keys + a couple of standard house keys.Durability remains to be seen. I'll keep checking.

This is the best Faraday key pouch I've had, by far! Others didn't block car key signals fully - this does, totally. Good size (holds car key - BMW- and tracker fob / steering wheel lock key easily. Belt loop on the pouch is useful for easy carrying (although it is easily carried in a jacket pocket) . Great purchase....does exactly what it's supposed to.....blocks all key signals.

Updated 18 Jan 2025. In daily use since March 2024 and has now failed. No sign of damage to any of the materials but no longer works as a Faraday bag. Make sure that you check yours regularly to make sure it still works. 10 months isn’t very good.Original Review (March 2024)I came across this after a recommendation from work colleagues who use this as protection for their PEDs (keys/laptops etc).Slightly too small for my car key making it a tight fit, but works extremely well. In the pouch and ‘active’ there is zero response from the car. My key shuts down when not moving so this just adds another layer of defence.Well made and unlike several other pouches in offer, the material is soft and so more comfortable when in a pocket.
