Please forgive me if this is a stupid question?

 

So I have been seeing a few adverts lately with regards to signal blocking bags/pouches to put your keys in. It's obviously not a stretch of the imagination to think there is a possibility that a signal could be intercepted and copied.

So I understand the distance involved is small, but is this something I should be concerned with? Should I look into getting a protective pouch of sorts? If so what sort of thing should I look for? Some are advertised as being faraday pouches, others just signal blocking. Some seem to say just indoors and others carried around with you.

 

Any advice would be gratefully received.

 

Warmest regards

It’s not a bad idea to get one, there are probably cheap diy options you could find.

A 2022 focus should have the newer key fobs that go to sleep after a short period of not being moved, so they don’t send a signal out.

As stated, a 'faraday' pouch is as cheap as chips compared to the potential loss of your car, just buy one for peace of mind, even if it does 'go to sleep' after a pre set period of time. I have never understood the development of this kind of security, though I was brought up in the 60s when Captain Kirk (Star Trek) use to lock villains in the brig using nothing but a force field, which they always overcame. Even at that tender age, I always wondered why they just didn't use a proper prison cell with bars, a lock & key!

You could just turn Keyless Entry off in the Vehicle Settings, that's what I did for a few reasons including security.

Faraday pouch = signal blocking.

I keep mine in a small aluminium coffee tin (once I'd consumed the coffee!).  I have heard an occasional story about a Faraday pouch losing its effectiveness, but that surprised me.

But I understand that newer cars like yours have keys which go to sleep after 40 seconds, but I expect your manual will confirm that.

That's interesting. Gonna go away and check on that one. Thank you.

A cup of Ovaltine and a pair of comfy slippers will help it on its way... LOL
