Does the job. Blocks the signals. Looks good.
If ever there was a solution to a problem that didn't ought to exist, this is it. But sadly the problem of relay auto theft has been thrust upon us, and so, if it concerns you, a solution is needed. A faraday pouch provides a cheap low tech solution by blocking the radio signals emitted by your "keyless entry/start" car fob,. Initially I made my own out of cardboard, aluminium foil and sticky tape. It worked absolutely fine but wasn't exactly stylish! So I looked to find something cheap but a little more resilient than my home made effort. This one certainly appears to be good quality and works provided you close the flap as per the instructions. I've only had it a few days so too soon to tell for sure how durable it will be,but first impressions are good and I will update the review if it falls apart! Standing by, or sitting in the car, and the car cannot detect the fob if enclosed in the pouch, so that's good. To open the car I don't actually have to get the fob out, i just have to open the flap in the direction of the car and the car can see the fob again so that's actually quite useful. It would be a pain to have to keep getting the fob out to unlock. Of course I do need to take the fob out to use the buttons to lock the car, but it's reassuring to know that once locked, with the fob back in the pouch it's secure. Pouch is quite large but not overly so. It means it is big enough to hold quite a chunky fob and maybe a second key if attached to it. I can't of course fit all the keys I would normally have attached to my car keys. but having my car fob in this pouch and my other keys on a separate key ring is something I'll just have to get used to. This pouch can still be slipped easily in back pocket of adult jeans or in my jacket's inside pocket. It's external dimensions put it around the size of a jeans back pocket. Slightly smaller. Overall very impressed and a pack of two for the price (as obviously the spare will need protecting too) feels like good value. I didn't have any problems like one review I read where key could be slipped into "wrong pocket" in the pouch and thus be unprotected by the metallic pouch. Mine only had the one pocket so maybe this has changed. So, if you are concerned about the possibility of a "relay theft" of your car using keyless entry, then I recommend this product. Of course, you can do the same thing cheaper if you really want to save your money... you can make your own out of cardboard, aluminium foil, and duct tape. Just make sure the foil fully wraps around with no gaps... but having tried both, I prefer this pouch! Recommended.

Inexpensive peace of mind. These pouches really work. Highly recommended.
I recently bought a keyless entry car and while its a bit unnerving at the start to walk up to the door, keys in pocket and just open it, I was even more unnerved to see CCTV footage of two car thieves creep up to the window of a house and scan the keyless entry key inside; open the car in the drive, without any damage, start the car and drive off. My wife is now about to buy a keyless entry car so, double the worry. I was therefore delighted to happen upon these little pouches and based on reviews took the plunge. These cases have a uPVC outer which is well stitched around the outside and has a generous and tight velcro fastened top flap. The entire inside is made of a gold material, similar to silk, which does the blocking. A car key with other keys attached on the ring will easily fit within the pouch, which I can be carried in a jacket pocket easily. Popped my keys into the pouch and tried the car door with the pouch and keys inside right up against the door handle. It stayed locked. Tried every door and tailgate. Same thing. Stayed firmly locked. I'm not sure how this pouch works; the thing is that it does. Still amazed that something so inexpensive could save your car from being lifted at your door, hi-rise garage or anywhere that a scanner chooses to lurk. I use both these pouches. One for home and the other for out and about. If you have a keyless entry car I can't praise these pouches highly enough.

A simple cheap wallet to protect your complex and expensive car
I recently bought a new car which features keyless entry and whilst it is a nice feature to have, the car industry really aren't up-to-date with what a security flaw this is. At night when you put your key somewhere 'safe' a would be thief can sit in your garden with a cheap bit of tech and 'extend' your wireless key range to fool the car into thinking you are nearby so that they can open the car and even start it. I knew all of this when i bought the car and that is why my first action was to buy a protective bag. For the price i was sceptical that it would work and when it arrived i was even more sceptical! There is no weight to the wallet and it looks very very low-tech, just a leather pouch. Ready to start the return process i placed the car key inside the wallet, walked out to the car and attempted to open it....... the car did not open. I then put the wallet (key inside) up against the windscreen, the car still would not open. I then removed the key from the wallet opened the drivers door and sat in the drivers seat, i then put the key back in the wallet and immediately the car dash reported that the key could not be found! I was impressed to say the least. So having tested the product straight away i was pleasantly surprised and can confirm that it 100% works. This being said, it will be nice to see how long this product lasts so i will be sure to come back in a few months time to report my findings! Pros: 1) It actually works 2) My Hyundai key plus 2 keyrings and one small key easily fits inside 3) Its nice and compact 4) You get two!! Bad Points: 1) It would be nice if it had a hook / loop so that you can hang it up with your other car keys at night 2) Would be fantastic if it had a seperate 'slip' that you could put your contactless bank card in... double whammy!

Funciona perfectamente con unas llaves de Seat Ateca que es para lo que las quería, ni al lado de la cerradura detecta dichas llaves dentro del estuche..

I wasn’t sure if this wallet would protect my key fob from being scanned but it works brilliantly. I can’t even start my car if the key fob is inside. It’s brilliant

nu een paar maanden in bezit en kom er regelmatig achter dat ik de sleutel nog in de etui heb zitten en gewoon weg heb kunnen rijden. Ook als ik langs de auto loop klappen de spiegels uit

Hab' die Hüllen auf Empfehlung hin bestellt - kamen heute an und ich hab' sie sofort getestet - Ergebnis: beide Hüllen schirmen zuverlässig ab! Sind zwar nicht sehr schick, die Schlüssel passen auch gerade so rein, mit dem kleinen Anhänger dran, aber dürften ja auch nicht größer sein, um noch in die Jackentasche zu passen. Ich war skeptisch, da ich nach den Diebstahlsberichten auch die "Schnelllösung" mit Alufolie (3 Lagen) getestet hatte, was überhaupt nichts genützt hat - aber diese Hüllen schirmen so gut, ab, daß das Fahrzeug auch dann nicht zu öffnen war, wenn Schlüssel in Hülle direkt ans Fahrzeug gehalten wurden.

Produit très efficace. A chaque fois que j'y insère mes clés je vérifie manuellement que les portes ne s'ouvrent pas et tel est le cas. Donc, rempli parfaitement son rôle.
