    This small, lightweight, flexible and durable "faraday cage" is popular with car owners, rental car companies and replacement remote key manufacturers to stop their keyless entry fobs from being remotely accessed.

    There has been a steady increase in the number of thefts of vehicles and their contents in recent years as the technology to manipulate keyless entry devices has become cheaper and easier to obtain.

    FobGuard® is manufactured in the US from the highest quality US made materials. A double layer of ultra high specification, US-made, conductive silver/copper/nickel material is stitched together. Then we wrap the faraday cage in a further layer of tough sports nylon to protect it from daily wear and tear. Finally it's sealed using conductive hook and loop in the mouth. This ensures your device is completely enveloped inside a true "faraday cage".

    The material has an average shielding effectiveness of -85dB in the range of 30 MHz to 1 GHz and an average -80dB in the range of 1 GHz to 11 GHz.
