Review on 🔒 MONOJOY Car Key Faraday Cage Large Box: Black & Red PU Leather Anti-Theft Key Fob RFID Signal Blocker - Securely Protect Your Vehicle Keys from Scanning Theft by Tim Roby

When you receive it, insert the key fob and see if your car unlocks or starts. It's always good to check. I tested my Silverado and this box works great. Nothing goes. Both keychains fit well. Depending on the vehicle, you can even install a third one. One modification I made was removing the dumb latch on the box. It was difficult to open and not up to style. Let's see...we've got a carbon fiber pattern, red stitching, and a latch that looks like it's from the 17th century. Oh well. The box closes securely without a latch and is much nicer to use and look at.
