briidea Faraday Box Key Fob Protector, RFID Signal Blocking Box, Faraday Box Signal Blocking Shielding Box for Car Key (Capacity(5-8Keys))

It definitely works because sometimes I put my keys in there and forget that I did and then I tried to use the AirTag to find it and it says AirTag not found lol so no signals are getting out of that box.It’s very functional is abuse is great considering it’s just flipping a latch aesthetically pleasing large storage capacity, We use this as a protector of our keys, so people cannot dup them The signal and steal our car. Ease-of-use is super easy because of the factors just a box It fits on my nightstand, but also will fit all of my keys on the keychain.Definitely provides an extra layer of protection.

Until a friend of ours in law enforcement mentioned to us recently, I honestly had no idea that the RFID transmitted from most vehicles key fobs could be copied and used to open, start and steal your vehicle without ever having the keys. Thieves have software that can detect and duplicate a key fobs RFID as its constantly trying to transmit to your vehicle at all times. Which is why many owners can start, lock, or unlock their cars from inside their homes, when walking out of a store, etc. Once it's been copied, it's like handing your key fob directly to the person wanting to steal it. Your vehicle's safety mechanism that shuts off your car if driven out of range from your actual key fob won't work since the thieves copied the RFID transmitted. Basically your vehicle thinks the key fob is always within range.Our LE friend said that many of these car thieves are paid by and are a part of a much bigger crime organization and many of the stolen vehicles are immediately shipped out of the country. So, he told us about these boxes that block the RFID when your key fobs are inside and to get one.As soon as this Faraday box delivered I unlocked our vehicles, put the fobs inside the box and sat inside our cars with the Faraday box to see if I could start the vehicles. Both vehicles said "key not detected" and would not start until I took the keys out of the box. This means it works!I kind of wish it was a little bigger but I didn't take into account having house and door keys on our key rings themselves so it does quickly take up space. I would just keep that in mind when picking the box size.The box itself seems sturdy and beyond simple to use. I don't see how it will ever stop working so I'm assuming this will be a one time buy. Plus, it's such a cheap purchase to help ensure our "not so cheap" vehicles!I highly recommend.In the photo, you will see I have the Faraday box (with my keys inside it) sitting on the dash and the message stating that the smart key is not detected.

Unfortunately my truck was stolen a few weeks ago. After doing a lot of research into how thieves steal cars (plug into the obd2 and use an antenna to boost signal from your key fob from inside the home) I decided to get a faraday box to keep my keys of the new car in.This box works. My car has keyless entry where you can just pull on the handle of the locked car (with the fob in range) and it will open.I put the keys in this box and walked up to the car (with box in hand) and car would not open.Also recommend looking into OBD2 locks.

The media could not be loaded. So I’m not so sure it completely blocks signal. It worked for not allowing the door to unlock when I had the keys in the box and it was closed. However, when I sat in my car and tried to start it with the key closed in the box my car still started. It should not start without signal from the key fob. That said, it did say no key detected so maybe it blocks the signal 🤷‍♀️. Overall I think sitting inside my home it will serve its purpose just fine as an added layer of protection. I live in a high crime area (life sucks and I don’t want to be here but it is what it is) and we have had so many cars stolen from right outside our front door. I was pleasantly surprised how nice the box was when I opened the package. It looks like a small jewelry box lined with black soft leather. It is small enough to fit in a drawer if you wanted or nice enough you could leave it out as decor.

Nicely made box, interior is has nice lining. Piece of mind to store keys.

This is a well made product that works like advertised.

When looking for ways to keep the spare car fob from constantly dying, despite not being used, faraday box (or bag) came up as too result. So I bought this, had good reviews (same as the more expensive one)...... I was skeptical that it would actually do anything. We tested it by outting both keyfobs in it, going out to car and trying to open the car, nothing..... however the moment the box opened, access was granted. Put the keys back in the box, sat in car with it, and tested start up....car wouldn't start. Open box, car starts. I'm very pleasantly surprised and recommend this....well worth the money.....the box is a nice, compact attractive box....we have four key fobs in it with room to spare.

We recently bought a new car with a smart key/smart key access and leaving it parked outside left me nervous after the rash of car break-ins we’ve been having. I bought this faraday cage box to keep the keys in so the signal couldn’t be repeated and the car unlocked.To test it, I took the keys in the box, and first tried to unlock the car. It wouldn’t unlock unless the box was open. I also tried starting the car and again, it wouldn’t start unless the box was cracked open (so moral of the store, make sure the box stays completely closed!).I just wish the box was a little bigger (I ordered the biggest size offered at the time. It’s just big enough for 4 car keys with a key chain each, not a full key ring with car keys and other keys.
