Samfolk Faraday Box with Faraday Bags for Car Keys, Car Key Signal Blocking Box, Keyless Entry Car Key Safe Protector Anti-Theft Shielding Cage

Works as advertised. Put key fob in box, take it out to vehicle, try to open door with touch on door handle, no response from vehicle. Pop open the latch, it still doesn't respond. Not sure why some others are reporting issues, but mine is rock solid. Peace of mind that no one can hijack my key fob wirelessly at my house. First 2 key FOBs with 1 also having house keys on them, cell phone, wallet with some room to spare (medium sized box) Only negative to report - the packaging was a hassle to get off. Very tight, hard to rip plastic and then a foam wrap underneath that. Other than clamshell packaging, probably the hardest item I have ever had to unwrap! LOL

Outstanding functionality. Outstanding quality. Outstanding price, especially considering the quality. I have a '24 Bentley Continental GT and a '25 Mercedes AMG GT63 coupe. Both cars are heavy on electronics. I put the keys in the box and went right to the doors of both cars, and neither car sensed the key. Then I opened the cars, put the keys back in the box, sat in both cars and still the cars didn't sense the keys. My home office is just the other side of the garage, so where I keep the keys is only about 20 feet from the cars. So this caused constant battery problems. I finally got smart and ordered this little box. Now I lock the cars in the garage and put the keys in the box, and the cars are then fully asleep, not draining the batteries 24/7. I am amazed that this box only cost $17.88.

Got exactly what I was looking for - a simple box I can place in a drawer to hold my keys and prevent thieves from picking up the proximity signal. With the box closed and the clasp latched, I took the box with my key in it up the vehicle and it did not recognize the presence of the key. As soon as I opened the box, my doors unlocked! Proof positive that the box is adequately blocking the key's signal. The clasp does have to be latched fully or else it seems that enough radio waves can sneak through the lid seam. Works exactly as described. The build quality is acceptable for the price and based on initial impressions, I think it will hold up well to daily use and is very easy to operate. The small size box is large enough to fit at least a few keys in it comfortably.

I got the large sized one and it comfortably fits 4 key fobs. (You could pile up probably 4 more but I don’t want to dig for the fob I’m looking for). The lock easily closes and makes it so you know the box is properly closed. I tested the box by trying to open my car door with the fobs inside the box and it actually worked. The car didn’t detect the fobs so I know my cars are protected when the fobs are inside the box. However, the inside of the box seems to get dirty/stained easily, so make sure your hands are clean, dry, and try to avoid touching the inside walls of the box if you wish to keep it looking brand new.

Works as advertised. Put both FOB’s in the box, closed it, walked right up to the drivers door, put the box less than an inch from the vehicle, VEHICLE DIDN’T UNLOCK. Opened the faraday box and the vehicle door unlocked and let me in.

Works great. My fob batteries would have to be changed about every two months. A battery guy suggested we get a faraday box because if the key is within 25’ of the car, it’s communicating constantly. This solved the problem.

AWeESOME !!!! holds 2 FOBS with keys attached and 1 on a lanyard , totally blocks signal , I stood right beside my car with 2 FOBS in a box and the car did not respond , total blockage of signal.

After having a car thief show up on our Ring system a few nights ago, I woke up the next day and did my research on relay theft and signal boosting. Yep, that's what he did. And as I told the police, in my opinion, he was a professional in the game. Luckily, he didn't steal the car or find anything worth stealing, or tear anything up trying. Also, without an actual key, he could not access the glove box. Please note that with the right electronic relay, a thief can start the car. Part of my learning process made me aware that a Faraday box could be tested. That relieved my fear of purchasing something I had no experience with, and hopefully, I wouldn't be wasting money learning. Note too that, prior to purchasing, I tried a test placing the car remote inside my double-sided Yeti water jug. It worked, and thinner, non-double-walled metal containers did not. Now the good news. After receiving the Samfolk Faraday Box the next afternoon, I tried different tests. One, with the remote in the Pouch/Bag inside the box, and then without. The box alone was all that was needed. Not only does it successfully stop any signal, but it's a pretty good-looking box, and well-priced for what's technically needed.

Exactly as described, well made, no complaints

Werkt perfect. Signaal geneutraliseerd!

A great product which works brilliantly to block the signal from our keyless entry car keys. You can stand next to the car with the keys safely in the box and the signal is completely blocked ….. open the box just a little and the signal is present and available, box works a treat ! Great price for the security of your car !

Muy contento con la compra, es super eficaz y cualquier cosa que metas dentro de la caja queda anulada por completo. Recomendable 100%
