Review on MONOJOY Faraday Protector Keyless Blocker by Ryan Huhn

Small package, strong protection! Bought 4 (don't forget a spare key when you get home - thieves can gain access to your car if the keys are in the immediate vicinity of your car (entrance table, side table, key rack, etc.), and take your car in the middle of the night) I packed these spare sets in a bag and put them away. When you are at home, put the fob (or all keys) in your pocket to block RFID attacks. I walked up to my car last week and knew all I had to do (usually) was touch the doorknob, I did and the door wouldn't open! The keychain was in the bag - so I KNOW this work - first hand! Get them for every vehicle you use to unlock your car, especially if you have keyless ignition!
