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 Bryan Fields

It definitely works. I bought it so no one can steal the passcode while it's in my house or a backup device, or my car can't be stolen while I'm at work. Works very well. The key cannot be recognized inside or outside the vehicle. I just wish it was small enough to just fit around my keychain so I don't have to take it out of that pouch and take it out to use the keychain. That's what I like about keychains, you can just put them in your pocket and leave them there. Spring. It's better to have some inconvenience than risk having my car stolen, which would certainly be a major inconvenience. I read a post that said someone can still steal the code while getting in or out of the car as the key fob needs to be open for you to use it. Although this is a short period of time per day.
