Signal Shield Faraday Box for Key Fobs, RFID Protector Box for Car Keys, Signal Blocker Cage, Car Theft Prevention Device, Signal Jammer for Keyfobs

Works perfectly I had the key fob inside the box while I was sitting inside the car and the car would not start. The car could not pick up the key fob RFID frequency while it was inside the box. The box is on the small side but it's very well constructed the lid seals nice and tight. The box looks and feels very elegant. I'm very impressed! Would definitely purchase again if needed.

Looks great, put the keys in the box close it went into the car push to start, vehicle advised keys weren’t detected. Great price & it works!!

Excellent product

Too small for more than just keys, phone wouldn't fit

Works and looks great! Brought it down to both of my cars and just as planned it does not open either of my cars. Open the box and everything works so it does its job well! It’s already on my Christmas gift for my family and friends!

I put my car keys in the box, latched it tight, sat in the vehicle and tried to start it. The vehicle stated it did not detect the key. I popped the latch loose and lifted the lid a bit and it still blocked the signal. Once the gap between the top and base was about 1/4" the car did sense the key and start, however, that was as expected.

Very nicely made and does the trick. We can easily fit 5 fobs in it

The media could not be loaded. So I was skeptical about whether it would actually block the signal but it actually does. It blocks my garage door opener, car alarm and remote starter. Really stylish and nice design with a leather like liner on the outside. Really like this and it actually does what it says it does.
