Man in the middle attack

Aldi have a pair of wireless-opaque key-fob pouches on sale for £4.99 right now. If you have keyless entry on your Mazda it is a cheap way to protect against theft.

They work. I had my fob in its pouch right next to the boot lock and I couldn't open it.

..and then you take your key fob out to open the boot.. and the protection is gone..

[Boyle de Cabbage]

That's not the point.

You store your key at home in the pouch and then no one can stand at your front door relaying the car signal amplified by his mate's car receiver and picking up your key-fob's unlock codes.

Boyle was just trying to prove the pouch actually worked - unlike the ones I bought from a 'police' shop in Bluewater!

Sure they work so will a baco oven pouch, the cars that are most at risk are high end cars - which as nice as we CX-3 owners like our cars they are hardly high end value models. Here is a list of the cars that failed a recent German test - the CX-3 is missing..

Perhaps as our CX-3 is not a high end car they didn't feel the need to test it eh? Although the CX-5 appeared to have failed their test (whatever it was?!?) as for a baco oven pouch blocking the cars signal, have you tried it? I've tried several metal boxes, foil lined containers etc and not one of them blocked the signal so I personally bought a pouch that would ensure my car is still outside my house in the morning if by any chance a couple of nonces with a box of tricks bought on eBay happened to be in my immediate neighbourhood during the night. Good luck to those owners of high end value cars who don't own some kind of signal blocking device.

The reason why some people complain about the Car Signal Blocker Faraday Cage Pouches not working is possibly because the Pouches have two compartments, the front compartment is not a protected compartment but the back compartment is. You should notice that when you close the Pouch the rear compartment extended lip folds over to completely seal the key fob within the pouch. After I placed my Keys with Fob into the Faraday Pouch, I then took the sealed Pouch out to the car and I could not open the car, therefore proving without a shadow of doubt that the Pouch had effectively BLOCKED the signal from my Key Fob within the Pouch.

[DaveG]

Totally agree with you Andy I always keep my keys when in the house in a Faraday pouch, why would you not want to spend a fiver to potentially
Prevent your car from getting nicked.
The scumbags also hang about in motorway car parks follow drivers inside and use the same trick as the drivers have their key on them some of the parking bays are close to the restaurant windows.
The anti theft advisors recommend you also keep your key in a Faraday pouch when out and about, although I must admit I don't bother.

[Boyle de Cabbage]

It's all very simple really: if you want peace of mind, you spend a fiver.

Possibly, but a read of the instructions should point one in the right direction

I also think it prudent to occasionally check the reliability of pouches as the continual opening and closing of the flap could damage the stitched in mesh rendering the pouch useless!
