Faraday Bag Key Fob, Colisivan Faraday Pouch Key Signal Blocker Fob Protector, RFID Key Guard Anti-Theft Pouch for WiFi/GSM/LTE/NFC/RF Blocked

This product worked exactly as advertised. Even standing right next to the car, with the key fob inside the bag, the car did not detect the presence of the fob.

This product does not do everything promised in the advertising. My key fob is properly inserted in the inside silver pocket and the flap is securely closed. Yes, the pouch does prevent the key fob signal from opening my vehicle's locked driver's door. This part is true. HOWEVER... once inside the vehicle, it does not block the signal from turning over the engine and starting. First of all, I do use the five digit keyless entry code for accessing the inside of the vehicle if, or when, I don't happen to have the key fob with me. My plan has been to keep the second key fob inside the vehicle, securely hidden and tucked away in the trunk/back hatch area, in the event that I were to ever lose or misplace my first key fob. The idea was to have this Colisivan Faraday Pouch as a way to block the key fob signal of the hidden second fob. Expecting the pouch to work in blocking the complete signal emanating from the key fob, the plan was to keep a thief from not only getting into my vehicle, but just as important, preventing the thief from driving off with my vehicle. OK, so the locked car door will not open with the key fob in the pouch tucked away somewhere inside the vehicle. Yeah, this part of the promise works, but this is the only good news. If someone were to somehow get into the vehicle, break-in or otherwise, all they would need to do is to push the start button and off they go with my vehicle. No thanks. I'm in the market for another signal blocker that can completely block a key fob signal, even when the key fob is hidden somewhere inside the vehicle. Disappointed...

I gave it 5 stars because this little pouch really does it's job. Blocks all signals. Will definitely recommend to anyone who wants to block signals. I have to take my fob out of the pouch in order to start my car, which means the signal does not go thru; which means it works!!

Bought these and another for my hubby new hybrid car with keyless entry.It came as a pair for each .It works. Won’t detect the key if inside the metallic part of the pouch.4 stars because the design has a flaw . My hubby placed it on the other side of its metallic sleeve at first and so he thought it didn’t work, so now he has to be careful.

Clunky - if you’re trying to minimize what you’re carrying this probably won’t help. Worse if you have multiple fobs, these really won’t handle more than one each. Meh.

Didn’t work it

Good value. Works as described.

I got this last week to help protect my new car. One for the spare key, one in the glove box when out and about and one at home for the nighttime. They work as expected, the price when you consider you get three is great. Delivery was fast and packaging was spot on. I don't have much of a use for the card protectors as my wallet blocks the signals but hey, its extra value. If you have a keyless car and 2 keys to protect this is the perfect product. Yes one is brown, the other is black however I keep the spare key locked away in the safe, my friends will never know!
