Faraday Pouch - Any Good News?

BobJohn123

Picked up my new car a few days ago (yay! 😃) & unfortunately it has keyless start (though still button entry). As fun as it is to press a starter button to bring the car to life, I would rather without the worry of a relay attack. 

I was looking at picking up another faraday pouch (had one a few years ago for a car that was full keyless entry) but looking at the long term reviews they all paint the same picture: after a couple of months the pouches stop working. Has anyone found one that is still going strong a year or so after purchase?  

I’m needing to get two pouches. One for the spare key (which never gets used so I could wrap in tinfoil) and one for my key. So recommendations or ideas would be great.

I don't understand how a Faraday pouch can stop working. Do they stop conducting electricity, or something?

My thoughts exactly but look at the Amazon reviews, there are too many people complaining about it to simply be folk lying or messing about. My understanding is that as the seems & joins get worn out the signal starts to escape. One person said there everyday pouch has stopped working but the one they kept the spare in was fine.

We went for a box.  Two of our cars are keyless so this holds both sets and we stick the keys for the other car in there anyway.

Isn't it just the keyless entry cars (i,e. those that you only have to be in close proximity with key in pocket) rather than those that require an actual button press on the keyfob (but that might not require a key to be inserted to start) that are the ones in danger of the relay attack?  I think with the one you're describing you should be safe from relay attack.

Autoexpress have some recent reviews. Rather trust their reviews than Amazon.
But use a Disclok. Ever since we found out the dealer cannot remove that option and there is nothing the menu to remove it.

 I thought on new cars now the keys deactivated if they're not moved for a couple of minutes?

I don't get this desire to overly protect the keys.
If they want your car and can't do 'whatever they do' to clone the key remotely and quietly drive off while you sleep, are they just going to move on?
Maybe with a nod of their hat towards your house and a mumbled "fair play guvnor, you got us there"
Or are they going to break into your house to try and find the keys?
Plenty of evidence of the latter.

The wire mesh shielding can start to open up and deteriorate and allow the radio waves to pass through it. Nothing to do with electrical conductivity.

I think most of the time it's fairly opportunistic - if they can't get the car to start they'll move on and look for an easier one unless it's particularly rare.

Because it's mine and why should I pander to the tea leaves?

Leave the keys under a pot then.
