Review on 🔐 Car Key Fob Protector - MONOJOY Faraday Bag: Keyless Signal Blocking, Anti-Theft Remote Entry Case (2 Pack), Black Pouch for Smart Fobs by Sammie Prince

I made this to prevent my car from being hacked or started with an RFID booster/repeater fob. My car is directly under my master bedroom, and my bedside table can be six to ten feet from the driver's seat. The pocket is big enough for my car key (which itself is in a protective silicone case) and the physical keys to my fob, which is very important. Many of these bags barely fit on a keychain. The bag completely blocks the RFID signal. Even with the key fob in my pocket in close proximity to the RFID antenna on my car's steering column (the limp home point where it would normally pick up the low battery fob's signal), the car will not be able to see the signal. and displays a message that there is no key in range.
