Why in this era of megatech have car companies still not found a solution to this??

Suspect that the driver didn't leave the keys in a biscuit tin or Faraday pouch.

Newer cars have remote keys that go idle after 30 seconds or so of not being moved, and so don't emit or react to the signal.

It says in that very thread that they have found a solution

Next generation of the keyfob from #Ford will have the "sleep mode" to prevent the relay attacks - if no movement detected for 40 seconds, the key will disable the transmission.

Apparently I can have my phone automatically unlock my car when I approach it. But my car is outside my house and I walk past it probably a dozen times for every time I drive it. Frickin' nonsense. 

Apparently land rovers are the worst for this. So I guess there's some upside. 

we have a Faraday box for this purpose although when I last tested it the hallway was just a bit too far from the car for the risk to arise

Isn't that the whole point of the kit they use?

If you've got one of those car keys that unlocks the car by just being close to it then they use a relay box to fool your car into thinking that the key that is indoors is actually next to the car so they can open it and drive it away.

I don’t have that type of key, but had assumed that you would need the key to be inside the car before it could drive away. Mad.

My car won’t start without the key being somewhere inside the car.

 

Terry - that’s why you see the bloke with the gear hanging around after the door opens until the car has started before moving away. It makes the car think the key is inside.
