DiyifeFaraday Box, [8-12 Car Keys Capacity] Large Capacity Faraday Cage for Car Keys RFID Box Key Box Signal Block Key Fob Protector Box Anti Theft Car Key Box for Car Keys, Phones (Black)

I was really looking forward to this product but after a few tests, I discovered it does not work at all. First, I placed my iPhone in the box and tried pinging it with my Apple Watch and the alert notification starting going off while sealed in the box. I also tried with two Tile Trackers and two sets of car keys; the Tile Trackers alarm went off within 15 seconds and I could still open my car. I am returning this product for a refund.In my video, I waited a couple of seconds before trying the door handle of my car but in multiple attempts off cemera, my keys were in the box over-night 10 feet away and I could still unlock door.

First the good, then the bad and the verdict.It works great with car fobs. Once you put the fob in the box and close it, It blocks the signals from outside and inside the car. As I hoped, I couldn’t start the cars. When sitting in the driver’s seat and box in my lap, my dash just keeps reporting “unable to detect key”. That being said, car fobs work on 315Mhz in North America.This box could not block any other frequencies like cell, gps or bluetooth. Would I buy it again or recommend it? if all i plan to put in it is my car keys then yes. If I bought it for any other reason I would be returning the product.

This product did not work as advertised. We placed our keys in the box, stood by our vehicle, and was able to start the vehicle. This should not have occurred as the box should have blocked signals.

Just purchased to store my key fobs as a deterrent to recent car thefts near my home. The boxes work perfectly to prevent signals from my key fob to be discovered outside my home. I verified this by bringing the closed box

I know it works, I tested it by putting my cell phone in it, it can’t be located or ring while in this box. I now keep my key fobs in it always. I had my previous new SUV stolen from in front of my house. They boost the fob signal to open the vehicle, then plug into the OBD port. I also blocked access to this port.
