VULKITVULKIT 1 Pack Faraday Pouch for Key Fob, Car Key Signal Blocking Bag with Hook and Keyring RFID Anti-Theft Faraday Key Fob Protector

I place my keys in this key fob and I walked up to my vehicle and I could not open my door once I removed my keys out of the key fob I was able to unlock my door I placed the keys back inside the key fob and I tried to start the vehicle my vehicle said no key was detected so once I removed the keys from the key fob I was able to start my vehicle it's really nice texture made out of leather and keep someone from stealing your vehicle it also keeps a person from being able to code your key from inside your house or your office or the store to access your vehicle I have already purchased one for my brother-in-law so he can use with his keys

Placed key fob inside bag and was still able to start vehicle and doors were unlocked automatically when I approached vehicle !!

As a faraday cage signal blocker it works well, I stood close to my car with the key inside and it wouldn't unlock, as a product it has issues. My cars key fob isn't overly large at 3.75"x2.75"x0.75" but it only just fits in to the pouch, the existing keyring on the fob has to hang outside the pouch. I only use it to store the key when in the house so it just sits hanging on the key hook but even so after a couple of weeks the hook piece on the pouch tore off so now I use the keyring to hook the key and pouch on to the key hook.Overall it looks good and works as intended but is smaller than expected and not well made.
