Did you know that while you're asleep, thieves can open and even operate your car without breaking into it?

Did you know they can do it using your keyless entry fob? Yep, the one that you thought was "safe" in your house, on your kitchen bench, on your bedside table, or even in your hands right now while you read this.

It sounds crazy, but thieves using a $17 signal amplifier can simply walk up to your car, open the door, steal your belongings, and then leave the car without any evidence of tampering. Try explaining that to your insurance company. Depending on car, they can drive it away too. Yes, REALLY!

It's easy and affordable to ensure you are never a victim. Our "Military Spec" Fob Guard can save you thousands of dollars in uninsurable contents loss or worse. Just put your keyless entry fob inside and your car is protected.

  • Thieves are using signal amplifiers to take the faint whisper from the key fob in your house and amplify it to make it heard by your car as if it was right in their hands.

    Luckily, you don't need to put your car keys in your freezer, but you do need to protect your keys with a car key faraday cage.

    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.

    This pouch 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.


    Field tests have shown 99.99% average signal attenuation. Customer testimonials prove that our design and materials outperform the competition. These pouches are built to last and can be reused over and over again with minimal shielding degradation.
