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

Had reports in our neighborhood that people had transmitter is trying to break in and steal cars. Tested my key fob and you could use it anywhere in the house. Got this box and it works perfectly does not transmit blocks of signal small size decent sits right on an end table next to the door very happy about the extra security and sweetness of the design.

Works as described. Protect the key fob signal from being broadcasted. Very easy to use, and appeared to be well-made. You can easily fit 4 key fobs, if not more.

I bought it and tested with my car. When the car fob is inside the box and I am inches away from a car, my car doesn't unlock, the signal is blocked. Since the box and keys are inside the house, some distance away from the car, I am very confident that no signal is coming to the car and it is safe. This box also looks nice. If you're worried about your car being stolen when parked at home, I'd buy this box.

I tested this box right away, as a threat protector against someone scanning our fob from a distance. It does work. I locked the car, waited a few minutes, then put the fob/keys into the box, closed it tightly (see more on that) and walked to the car. It would not open. I then took the fob/keys outside, got in the car, reinserted the fob/keys into the box, closed it tight. And the car would not start. My only gripe is the front latch, you really don't need it, I'll probably remove it. You just want an RF proof box, it doesn't have to be able to survive lunar exploration or deep sea diving. Also, you have to close the box all the way, if you just drop the lid it doesn't work, and the box is sort of tight to get open and closed, but hopefully it does loosen up over time. Overall, it works.. and it's inexpensive for a good piece of mind.

I purchased the Briidea Faraday Box Key Fob Protector a few years ago, and I’m genuinely impressed with its performance and design! This sleek, leather-lined box not only looks stylish on my entry table but also delivers on its promise to block RFID signals effectively. I tested it with my car’s key fob, and it completely prevented my vehicle from detecting the signal—neither the doors unlocked nor the engine started when the fob was inside the closed box. The box is compact yet spacious enough to hold multiple key fobs, making it perfect for our household’s needs. The sturdy build and secure latch give me confidence in its durability, and the premium RF shielding inside ensures peace of mind against potential keyless theft. It’s easy to use, and the elegant design blends seamlessly into our home decor. For anyone looking to protect their car from signal-cloning thieves, I highly recommend the Briidea Faraday Box—it’s a small investment for significant security

works well and shields like it claims. box seems well made. it holds 2 sets of keys with several keys no problem

I received my box yesterday (10-28-25). I put both my fobs in the box, but I made sure my car was locked. Then, I went to the garage and stood next to my car with the box in my hand. I attempted to open all the doors of my car, but the doors would not open. The briidea Faraday box works! Worth the money. The box is big enough to hold 3-4 fobs. Make sure the box is fully closed.

Works great

I bought two of these boxes, and I just received them the other day. My vehicle is a 2014 Jeep Grand Cherokee SRT that uses a keyfob. For my vehicle, I keep the keyfob in my pocket and can open and lock my doors and back hatch by touching the door or hatch handles. In addition, when I start my vehicle by push button, and my foot is on the brake, the vehicle checks to see if the keyfob is inside the vehicle. If it is not, then the dashboard will display "No keyfob in vehicle", and not start the vehicle. I put one of my keyfobs in one of the boxes, closed it up, and tried to open the doors and the hatch. As I was trying to open the doors and hatch, I rotated the box in various directions, but was never able to open the doors or hatch . I tried this with both boxes, and I was unable to open the doors or hatch with either box. So I opened up the top of one of the boxes, with the keyfob in it, and I was easily able to open up the door with no trouble. I then tried to start the vehicle with the keyfob inside the fully closed box, which was inside the vehicle. Again I rotated the box, while repeatedly trying to start the vehicle. No luck, the vehicle would not start. I open up the box and tried again, and the vehicle immediately started up. So in summary. The box (actually both boxes) I bought works exactly as described. It is a nice size, well made, and a reasonable priced. It works perfectly for my vehicle and keyfobs.

Helps keep your cars fob protected from lowlifes wanting to electronically stealing your car

Value for money

We store our spare keys and remotes in this box. If I take the closed box full of my car keys near my vehicles I am unable to open the cars. Exactly what I wanted!
