Don't rely on Faraday Pouches

[Penguin68]

Just a heads-up that my 3 months old Faraday Pouch (for car keys) just failed - luckily I was aware of this and was able to move my key fob to the second pouch set which still works. But it's worthwhile trying to open the car with the fob in the pouch just to make sure it's still working. These failures are not unknown - the mesh inside the pouch becomes compromised through use, apparently,

But don't rely on them without testing. There are regular bouts of thefts of key-less entry cars (you do need specialist equipment to 'steal' the signal) - one at least was stolen from my ED road last year with the owner insisting that the key was in its pouch at the time!
