Faraday Cage

[Lamprey]

I have read several articles in the past about people (thieves) extending the wireless range on key fobs in order to gain entry and even start cars. Here is one article. I keep my car in a my garage so I've not been too concerned with this issue. I've heard of people putting their keys in the freezer to shield them, but I've also seen products you can put in your pocket to shield the fob.

Just curious if others are using any sort of shield/faraday cage for their fob either at home or when you go out?

... I've actually never known someone to have actually had their car stolen let alone keep keys in the freezer...

I've had cars broken into but I am with you. It would seem that if this was the case it would also be a problem with garage door openers? I would presume things are a little more advanced than "Gone in 60 Seconds" using a radio transmitter and all things using revolving codes. Regardless it still appears that the attack must originate within range of your keep fob. If this was at my house the attacker would be at closest standing at my door, then he would attempt to pick up the wireless fob signal and talk to hte car?

Garage door openers and active key fobs are two completely different things, granted both can be compromised. In the case of the fob, the "hackers" can extend the range of your fob so you'd never know your car was opened/started because it is active.

I'm not trying to fear-monger or anything as it's pretty hard to stop someone whom is determined to get your shit. But, just curious.

Some more info for anyone interested (in German):

Thanks for the info! My car and I now have matching tinfoil hats!

The way I understood the recent type of attacks is they have a receiver that when you you hit your key fob to unlock or lock your car from a distance intercepts the signal and reads the code that pairs your key to your car. Then they can come back later and open your car using that code.

This type of attack would not be mitigated with a Faraday cage. If you were worried about keeping your keys "exposed" I suppose you could always use something like the bag they ship EZ-Passes in that blocks out all signals. An RFID blocker might also work. I know sometimes Law Enforcement uses these types of bags to put digital evidence in to prevent remote access/tampering of things like Cellphones and other mobile devices.

i feel like this is what insurance is for. hold on lemee grab my keys from out the freezer. LOL

Gonna go with a 88-89 Acura Integra under all that tin foil...might be a conspiracy theory

is this thread for serious?

I thought the same thing upon the first post.

Good eye. I actually disguised the S4 as an Integra before doing the tinfoil wrap; good luck stealing my car now.

i mean years ago i saw the articles and the videos of how thieves hack cars overseas by this same process, but is this really that much of an issue? I mean is it really??

do people prize their cars that much that they resort to sticking their keys in a freezer or any type of faraday cage? as Johnny mentioned, isn't it why people have insurance?

[14S4GWM]

^ I dont care enough about it or care to read about it. Oh well if it happens

[bberg22]

I agree that sticking keys in a freezer or faraday cage is extreme but even with insurance it may be hard to get back the true value of a car. Things like mods and time spent working on the car etc are not usually recuperated from insurance payouts. If a car is stolen and recovered the insurance may not pay out and you would be left holding a car that was beaten or abused or something. The value of the car to someone may be higher than the insurance's book value, meaning you may not be able to get a comparable car with the insurance payout. It seems like a legitimate worry but not something that I would think happens often enough to take extreme measures against.

That only works once. Basically, they intercept the first code and blocks it, so the car doesn't unlock. The driver thinks nothing of it and hits it again, but this time the hacker records the second signal but sends the first one. The door unlocks. The hacker now has the ability to send the second code whenever they want, but it will only work once.

That said, that's only active transmitting fobs. This isn't true for Intelligent Access. To my knowledge, it's not possible to spoof the intelligent access systems at all, so the only thing that can be stolen is the remote pressing a button to unlock from a distance.

Good point. But it does only take one time to steal a car.

I've never even thought of using one of those. However...., my friend's Raptor was stolen out of his driveway. Which is across the street from mine :O
