Living in the land where this problem seems to be highly prevalent I have o= ften considered this. I'm wondering if a standard antistatic bag is enough of a faraday shield, t= he IR reflective film on my office windows are enough to stop a GPS receive= r working, so I suspect an antistatic bag will be enough. Has the added adv= antage you can still identify the correct button to push to try and unlock = the car to prove it is a good enough shield. -----Original Message----- From: piclist-bounces@mit.edu On Behalf Of Russel= lMc Sent: 09 July 2018 12:21 To: Microcontroller discussion list - Public.

In this article a number of senior security experts are reported to recomme= nd wrapping car electronic key fobs* with tinfoil when carried daily and ma= ybe storing in a metal can at home. The aim is to create a Faraday cage to foil (groan) "cyber-thieves' " attempts to copy the unlock codes.
