Faraday Bag Faraday Key Fob Protector, Car RFID Signal Blocking Pouch Protector, Faraday Cage Fob Guard for Keyless, Cars Security Anti Theft, Anti-Hacking Case RFID WIFI Blocker Box, 2 PACK

I bought these to help keep the codes from being picked up by thieves. One of our cars uses the fob to open the door and start the car and this protector works like a charm. You can be standing right beside the door but it will not open until the fob is taken out. All the different fobs we have fit in it nicely and there is extra room for things like your license or for paper money. I highly recommend these.

MUCH TOO LARGE!!! Just wanted something to put my car’s key fob in ... this thing is like having another purse! Definitely not what I wanted or expected

It’s a two pack but only one works. One blocks the signal but the other one doesn’t, car unlocks with the fob in the bag.

I really didn't like that it is big and bulky, but I am able to use it and it can fit all of my keys that are on my ring along with the fob. SO in the end it works good.

So far, my car has not been broken into (I keep my keys in this pouch daily/nightly when not using my vehicle). I live in the city and I find this product to be very useful. I would recommend.

I bought this product to stop thieves from opening my car's door using the keyless entry feature!It worked for a while as I could not open the door even standing next to my car and I was satisfied.But after one month or two, I noticed I can open the door even with the lid closed and the bag in my backpack!There is no evidence of any gap or hole or crack on the bag, but signal seems to be leaking out of it anyway!Now this bag is useless for me.

The faraday bag appears well made and durable. I like the dimensions and ease of use. The attached clip provides alternative carry - clip to belt loop, neck ID lanyard or other similar items. I tested the bag’s effectiveness in blocking the key fob’s rfid signal and it worked well.

Did not like look of product
