These fob carriers do block the signal. I bought one that is like a softer, flexible pouch and one more like a stiff envelope. The pouch style has a hook for the key on the inside and a strap to carry/hang it on the outside, bottom. I think you’re supposed to keep the key fob attached to the inside so it’s always guarded, and then roll it back somehow to expose it for use. But I find the material very difficult to roll back, so I just drop my fob in the pouch and added a clip to close it. (Maybe I didn’t get how to use it properly!) The other design is easier to use, but larger. My husband doesn’t carry either style in his pockets - too big. But he does use them to store key fob once in the house.
Love all silent products !!!
Works as advertised
Choice & navigation were easy, price was right. Delivery was timely, and the cage works just fine.
These key fob guards are great and they work as advertised. I put my electronic key inside and my door would not unlock. Blocks all the signals. Would definitely buy more if needed.
