What Is A Faraday Pouch
From Wikipedia: "A Faraday cage or Faraday shield is an enclosure used to block electromagnetic fields. A Faraday shield may be formed by a continuous covering of conductive material or in the case of a Faraday cage, by a mesh of such materials. Faraday cages are named after the English scientist Michael Faraday, who invented them in 1836."
Because your keyless keyfob uses electrical signals to open your car, start the engine, this means that it can also be controlled or used in a way which is detrimental to you.
So placing your keyfob for your car in to a faraday signal blocking pouch should give you added protection.Back to top
How To Use A Signal Blocking Pouch
All you need to do is keep your key inside it's pouch when you are not in your car, it's that simple. Just make sure the pouch is closed and sealed when on you, in your pocket or in your home.

This is a review of the Hyton Car Key Blocking Case
The Hyton Car Key Signal Blocker case is a small and lightweight fabric pouch. It comes as a pack of two and is made of specific fabric layers to create a 100% signal blocking pouch.
It is designed for a car key with fob in mind, however it will also fit cards or a small smart phone inside but not all together. You aren't going to get a large phone in there either such as an iPhone 6 or CAT S60.
The pouch can block RFID, NFC as well as WIFI signals, which is handy when you need to switch off from connecting with your phone is situations such as when you are driving.
The inner layer of the blocker uses a RFID nano-shielding material that encompasses the car key or phone inside with a 70-90db shielding ability. A car fob has a signal strength of 58db which means it is safe within the pocket from theft. There is a white cloth that is strong and helps protect the inner layer from scratches. The pouch uses strong stitches and closes with velcro. The outer layer has a soft waterproof leather like material which also helps to make this a robust and long lasting case.

This is a review of the MONOJOY Car key Signal Blocking Harris Tweed Pouch
The MONOJOY Harris Tweed Signal Blocking pouch is a beautiful looking signal blocker. It is unique in design and is handmade using tweed from the Isle of Harris in Scotland. Tweed like this is a fantastically useful material for the outside of the pouch as it is water and wear resistant. It is also hard-wearing and abrasion resistant.

It is extremely well crafted and includes a small D ring for the pouch to be attached to your bag, or somewhere to prevent it being snatched of you, or to attach a handle to.
To the inside of the pouch is a gold liner this is an RFID blocking sleeve that is the section that is the signal blocker, proventing car fob signal, WIFI, 4Gand NFC. It will easily fit any car fob or mobile phone, there is some give to the fabric. Then this will easily fit in your bag and you could potentially squeeze it into a pocket.
What we really like about this company is that they have a couple of versions of the Harris Tweed faraday signal blocking pouches. Below you can see a smaller version, in grey which has a keyring lock on it which makes it a little bit more practical as well.
The smaller pouch can only fit in an electronic keyless car fob key, but that is all you need for this security feature. Just like the larger wallet sized version, it protects you from different wireless insecurities.
If you want a smaller option with all the security features, this should be your choice.

This is a review of the Alpha Shield Key Protection Blocking Case
The Alpha Shield Signal blocking case is a hard box made from aluminium. Although it is not convenient enough to just fit in your pocket it is small making it easy to stow in a specific "key" cupboard or in your glove box. It is also surprisingly lightweight, from the picture it looks quite heavy when infact it is only 15g.
Shaped a little like a small sandwich box, its easy to clean and makes it robust against dropping. As an actual sealed case this should block the signal completely when the box is shut. It does recommend waiting at least 30 seconds before expecting the box to work. The case also is only limited to the makes of cars it will work on. Car key fobs that will not work on Ford, Jeep, Mazda and SEAT, information is a little misleading as in another sentence it says all cars makes are suitable.
The box could do with being bigger as if you have two car fobs they will not fit in this box together so you will need to buy another box and two of these boxes them makes this a slight inconvenience to stow. It also only can be used for car fobs and bank cards but not any phones which is a shame.
- Hard case
- Small and lightweight
- Convenient shape
- Easy to clean
- Next day delivery with Amazon Prime
- Won't fit in your pocket
- Not suitable for some makes and models of car fobs
- Too small for some car fobs
- Two boxes to accommodate both your main and spare keys takes up space
- Not the cheapest available
- Cannot fit a phone in
The Alpha Shield box is small, compact and only works for a number of car fobs and unlike other security signal pouches we have reviewed, doesn't work with smart phones.
