Strictly speaking I don't think they are faraday pouches, rather just RFID blocking pouches. The term Faraday has just been borrowed as a generic term for something that blocks signals.

They usually block phone signals (bluetooth/wifi/mobile data/etc.) as well, I know the one I have does (did :mad:

)

Anyway. As above, my pouch is no longer working, I test it monthly and this morning the car would unlock fine with the fob in the pouch, so I need a new one (I've requested a replacement anyway as it's less than a year old, but my guess is that's unlikely to last any longer).

Are the little boxes better than the pouches? You're not constantly wearing the material putting the key in and out, so theoretically yes? Anyone got any recommendations?

I’m looking at vonetti alpha shield box on Amazon. Not cheap but then neither is the car! I’d hope it will last longer than a £7.99 pouch.

As I understand it, faraday cages do not block outbound signals, only inbound, unless they're grounded.

They block signals getting through the cage. Signals from inside are fine inside but cannot get outside.

Not keyless, but I keep my spare key in the sock drawer in the bedroom at the back of the house.

Always keep my keys in a metal tin, both spare and main key

Yeah I saw that one when I was searching - it does look nice, but then it's pretty expensive for what looks like essentially a zippo lighter with the insides taken out

Most of the cheaper boxes look like they're just a normal cardboard box lined with the same (apparently quite fragile) material the pouches are made of, so longevity is again questionable
