Or the "clack-clack" of a shotgun, and (I believe) Mr Airsoft's epic speech! That will pretty much change your mind about your life choices of crime!

If you have a newer vehicle with a proximity key, then a faraday cage WILL WORK to prevent these type devices from allowing access. Your vehicle has a communication module and antennas that are looking for your proximity key. When you get within range, the two devices communicate and your door is unlocked. Devices have been engineered to extend that range, acting as a "repeater" between the vehicle and your key fob, allowing them to communicate at a much greater distance, and then your vehicle is unlocked. If you put your fob in a faraday cage, steel box, safe, etc., then it cannot communicate with the vehicle.

BE SURE ANY SPARE FOBS ARE LOCKED UP AS WELL! IT DOESN'T DO ANY GOOD TO LOCK UP THE ONE YOU USE WHEN THE SPARE IS IN A DESK DRAWER SOMEWHERE.
There are separate and different devices, known as "code grabbers" which work by receiving your signal/code when you hit "unlock", allowing the perp to come back at any time and unlock your vehicle. This device would have to be within range to receive your "unlock" signal. I believe that these are not being used much these days, due to better remotes (code hopping), and the fact that they have to be within range and ready when you hit "unlock". If this type of device grabbed your signal when you hit "unlock", then they have it, so putting your fob in a cage later does no good.

You're just isolating YOUR FOB. (Now just the FOB you isolated won't work)
The device imitates the signal from your FOB, and others from the same signal range for FOBs that the manufacturers use.

You'd have to use a Faraday Cage around the receiver IN THE CAR in order for this to work, and therefore rendering your FOB useless.

You guys' experience is the opposite of mine. I've got a faraday cage fob holder and I can put the fob in it, walk out to the car, put the fob holder anywhere I want, even directly on the door handle and the doors won't open.

So some of them work, and some obviously don't. A properly designed and constructed faraday cage will always work as it won't allow any signal leakage at all.

Here's the one I use:

No:
You put YOUR FOB in a Faraday Cage. This isolated THAT FOB. (This FOB is also SENDING the signal)

Now take your second FOB and watch it open the car. (The RECEIVER is in the car, unisolated)


That's what the device does. It mimics or duplicates the signal coming from the FOB you have in the Cage.

That's actually one of the ones I bought tried, it didn't work. Last Purchased date is up toward the top of the screen grab.



I believe it's even mentioned in the reviews a time or two that they don't work on all vehicles, apparently Dodge and Ram would be some of the ones they don't tend to work for. Tried it on my daughter's 2016 Ram 1500 and Wife's 2018 Durango. Could unlock and start both vehicles with the Fob sealed inside of all 3 brands I tried. I honestly don't remember which others I tried, I just clicked the link you posted and saw where it was one of the ones I had tried.

Works perfectly with Ford, or at least with the Ford Bronco Sport.

There are 2 pockets in the pouch. Did you put the fob in the correct one? If you put it in the wrong one, it doesn't work at all.

There are 6,592 ratings for the pouch. 8% of them said it didn't work and 92% said it did work, so 528 people say it doesn't work and 6,064 say it does.

Makes me wonder if they all put it in the wrong pocket.

Edited to add: I saw this on one of the ratings and it actually makes sense it wouldn't work if you do this. The guy left 2 it and it sounds like he left them hanging out of the pouch. Even if the keys didn't act as an antella, leaving them hanging out means the Faraday pouch is no longer a faraday pouch because it isn't totally sealed. Here's the text of his rating:

UPDATE: After a few weeks I found that it stopped working. BUT the reason was because I attached 2 of my most used keys to while it was in the back pocket. That made the difference. Maybe the keys acted as an antenna when link to the fob? I dont know.

Man, I have no idea and I’m not even going to try to figure it out.

Just a little bit of related information, there was only ever one Fob in the Faradays at a time. I started out with the spare for the truck, didn’t work. That’s what made me grab the spare for the Durango, same thing.

Tried it in all 3 different brands. Same result each time with both vehicles.

I wish it would have worked for the obvious reason of added security, and they apparently do in most cases. I’m not saying the product doesn’t work in general, or is garbage, but they don’t work for every application. Hell, I’ll buy another one and video me putting a Fob in it while still being able to access and operate the two vehicles I’ve previously mentioned. The cases may, and probably do, still dampen the signal coming from the Fob enough to where they can’t be scanned while zipped up inside but some of the reports I’ve read about are claiming they can scan the codes out to 100 yards.

Once I found it wasn’t working for us, I went ahead and just switched over to anti theft.
