Faraday Bag Signal Blocker Disklabs KSH KS3 Key Shield Home Larger RF Shielding

These bags are the real deal. I wouldn't suggest going for whatever is cheapest on Amazon; instead, look for a credible product from this brand.

Excellent, effective and large key pouch to prevent the scrotes stealing g your pride and joy. Used it from day one. Easy to open and close. Effective signal blocking. Worth the money.

I have had to change my car and my newer one has a 'keyless' entry, I just have to be near the car with the key in my pocket and the door will open. I am keenly aware of the thefts of vehicles by thieves using some kind of booster that can open doors without having the key. I'm not sure if my car would start without the key in it but it was a risk I wasn't prepared to take. I carried out my research, and yes Disklabs is probably one of the priciest BUT it is also the only one that has been police approved 'secured by design' so that's the one I ordered. It is exceptionally well made. I got the bigger one to keep both keys in, they fit with plenty of room for both sets and I can confirm that my car door will not open at all when the pouch is shut fully. For me it is peace of mind and money well spent to protect my car. I would definitely recommend.

Big enough for car key and keys ring with other keys on.

Does a good job. Several years later it is still going strong.

To really know how good this is I would have to have an attempt made on duplicating my keys, however, the bag seems to be of good quality and it looks quite good overall. The functionality of this verses price is probably quite questionable in many ways, its quite a lot of money for something that may never happen but provides a degree of peace of mind.
