That's why I also have this fancy schmancy Faraday Box:

https://www.amazon.ca/Faraday-FOXNSK-Leather-...

I even tested it in a couple of ways.  Walking up to my car with the keys in
the box & the doors wouldn't unlock.

Opened the box and got in the car & then closed the box again.  Pressed the
button to start the car and the dash says "No Key Detected".  Opened the box
and started the car, then closed the box again.  After about 30 seconds the
"No Key Detected" message came back and wouldn't let me shift out of park.

I also tried it with the Apple AirTag (bluetooth tracker) on my keys.  With
my keys in the box, my phone cannot find the tag at all.  They can't be
located or receive the signal to play a sound.  Here's where it gets
interesting: If I unlatch the box but keep the box closed, the AirTag will
receive the signal to play a sound, but still can't be located.  So I suspect
the latch plays a role in either completing the cage or just holding the box
closed tight enough for the protection to work.

Either way, it's a neat little box that kept me amused for about 45 minutes
testing various scenarios.

Depending on the method used, a lot of these are just amplifying/relaying the
signal from the FOB.  So it is encrypted between the car & FOB, it's just
receiving a some help extending the range between the two.

There was another one I saw where someone could capture the signal over the
air to unlock the doors and "replay" it as many times as they wanted to unlock
a car.  THAT is just poor design!
