Review on 🔒 Diyife Faraday Box, Frosted Version - RFID Signal Blocking Box, Key Fob Protector & Car Key Signal Blocker Box - Carbon Fiber Signal Blocker for Keyless Fob, Phones, and Car Keys by James Cross

This box works as advertised. I bought it to store my family's car keys after learning of car thefts outside houses and in driveways. It's as simple as it looks. Put the keys in the box, close the box. No signal can be tracked. I went to my wife's car to try and open it with the keys in a drawer that he couldn't open. He took the keys out of the box, the car door opened. When you used the handle in the car with the key from the box, it worked. Turned car off, put key back in trunk, tried to start, car wouldn't start. This product works.
