If you do not have the key fob about your person or you are not close enough to the car, it will not unlock or allow you to start the engine.However, criminals are now using a signal booster to pick up the signal from your key fob inside your house and relay/boost the signal so that your car thinks the key is within range, allowing the doors to be unlocked and the car to be started and driven away without you even realising.The RFID Signal Blocker Case from FUYUAN can prevent this type of theft from taking place.The case is approximately 20cm x 10.5cm, is made from a strong nylon material and has 2 pockets inside.The first pocket is just a regular storage pocket and will not protect against the theft of your car.The second pocket is gold in colour and forms the Faraday cage around your key fob, which prevents the signal from being detected.***** In The Box *****1 x RFID Blocking Case***** Installation / Usage *****To use the case properly, you simply place your key fob inside the gold coloured pocket and then fold over the flap, sealing your fob inside the Faraday Cage with the Velcro strip.Once inside the Faraday cage, the signal from your key fob cannot be detected.You can also place other items that use radio waves (such as a mobile phone, or your passport or contactless credit/debit card). Placing them inside will mean that they cannot be detected and they will not be able to pick up a signal.***** Conclusion *****For less than £10, this is a great way to help protect your expensive car from easily being stolen.The case is a good size and should easily fit any car key fob. I really like that the protective lined pocket extends past the fold of the case, as this means that the pocket folds over and seals your fob inside, preventing any leakage of radio waves.I have tested the case with my key fob and I was able to hold the case against the door handle of my car without the car being able to detect the key.I have 2 of these cases (1 for my main key and one for the spare) and would have no hesitation in recommending them. ### ⭐⭐⭐⭐ RFID Large signal blocker. *by on Reviewed in the United Kingdom 14 June 2018* Just tested, works well,In fact works better than my smaller one, i have for my remote. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/57932858-faraday-pouch-for-car-keys-faraday-bag-for-car-keys](https://www.desertcart.pt/products/57932858-faraday-pouch-for-car-keys-faraday-bag-for-car-keys) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-11-15*
