Samfolk Faraday Box & 2 Pack Faraday Bag, 8.42" x5.19" x 2.76" Faraday Key Fob Protector Cage, Signal Blocking Box Faraday Key Fob Protector Anti Theft for Car Keys Keyless Entry Car Key Protector

I tested this box by walking up to my car with the keys in it, and the car did not detect them. I got in the car and it wouldn't start until I opened the box. These work very well. I recommend keeping one at home, as thieves use repeater devices to steal your signal and open/steal your car while your keys are safely at home. Protect yourself.

Works good. Blocks any attempts

Nice box and bags good for protecting key fob and credit cards. Tested and working as advertised. Was looking for something to protect key fobs and credit cards. A tad bit small as it quickly fills up once you have two fobs inside but would have probably gone for a bigger size. Overall a good purchase with value for money. Easy to use but not so sure on the durability of the front locks over time.

It's a nice box, very sturdy looking and good latches. My only concern about it, is that when you lift the top up it doesn't stay in place. You have to hold your thumb to hold it open. It could have a little bit more Flex on the material so it can bend back further back to stay upright by itself. But other than that it's very nice.

This works well, we keep it at the front door so it's easy to access. It holds 4 keys easily more if you stack them. I tested them with both of our cars, I held the closed box with the keys inside right next to the both cars and couldn't open the door. I took the keys out, opened the door, put them back in the box and then could not start either car. It also looks nice and is well built, it seems to shut very tight, nice tight tolerances. Highly recommend!

I had to buy a new car. While we were signing papers our sales men said get a box. Ok. This was new to me. The box protects your car from being stolen. My hubsand uses the box. I use one of the pouches that came with the box. The next day a friend called and said someone tried to steal her car by coping her key fob. It didn't work. Don't hesitate, this is a great product.

Seems to work as it should. With the growing number of thefts of vehicles that have push button starts and unlock when one pulls the handle when one is nearby with a key fob, (thieves scan for the signal that your fob emits, duplicate it onto a blank key fob and drive off with your vehicle), using a Faraday Box and Faraday pouches/bags is essential. The box is big enough for my wife to put her voluminous key set in, and we keep unused fobs in the box as well. I turn off my fob's emitter (hold down the Lock button and press the Unlock button twice) and put it in the Faraday pouch for double protection. Having heard of thieves waiting for a "Lock" signal and then stealing a vehicle, I'm also tending to use the Lock button on the inside of the driver's door to lock the car rather than the fob and then put the fob in the pouch. All the manufacturers' "convenience" and features for customers is also making it "convenient for thieves to steal our vehicles. Do what you can, be prudent, but don't lose sleep over it.

The box is actually stylish and I must purchase another for my other vehicles
