Comment Faraday pouch (Score 2) 177
I started using a Faraday pouch in my pocket long ago because I knew this day was coming. This security vulnerability was demonstrated years ago but it never got attention of the media until these devices became available on the dark web and cars actually started disappearing off the streets. The insurance industry has since finally woken up and so will be your insurance rate.
I bought a Faraday pouch and trimmed it down so it fits neatly in my pocket where i drop my keyfob into it and have a chain connecting to my other keys. Its easy to extract and put back in the pouch when not in use. The only time it is actually exposed and its signal able to be intercepted is when I am driving. They would have to follow me around until I park someplace, or intercept the signal there using a yagi antenna setup, and then steal the car. They would have to be very dedicated to stealing my specific car to pull it off, and this would not be worth it with so many other cars on the road just like mine that are more much more vulnerable.
The Faraday pouch is cheap enough, you just need to remember that your door is not opening for you by grabbing the handle until you fish out your keyfob. It makes it more of a pain to open the trunk when carrying groceries but that is the price of convenience. Walking out into a parking lot with no car to be found is a lot less convenient. A pouch is a good investment.
