Did you know that while you're sleeping, shopping or at work, thieves can open and even operate your car without breaking into it?

Did you know they can do it using your keyless entry fob using a "signal amplification attack"? Yes, that same fob you thought was "safe" on your bedside table, in your pocket at the supermarket, or on your desk at work can have its signal stolen and used by a thief up to 1,000 feet away to open your car and in many cases then simply drive it away!

"Hundreds of thousands of vehicles in driveways and parking lots today remain open to the wireless theft method" - WIRED

It sounds infuriating, but thieves using a signal amplifier made from cheap, readily available parts 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 your car model, they can drive it away too.

It's easy to ensure you are never a victim. Our patent pending "Military Spec" FobGuard® security pouch can save you thousands of dollars in uninsurable contents loss or worse the loss of your whole car. Just put your keyless entry fobs inside a FobGuard® security pouch when you're not using them and your car is protected.

This problem is getting worse and it's not going away. The devices used to do this are becoming easier to buy, cheaper to make and more powerful every day. There is no known solution except to put your key fob inside a faraday cage you can trust to protect you, and FobGuard® brand security pouches are the best there is. Buy a FobGuard® security pouch today for each of your fobs.

  • Thieves operate in pairs and take the faint whisper from the key fob in your house, work or on your person, and then amplify or relay it to make it heard by your car as if your fob it was in their hands! Here's how it works:

    1. The first thief "listens" for your fob signal. They might follow you into a store or cafe, or stand next to the wall of your house.
    2. This thief "amplifies" or "relays" the signal to an accomplice who is standing next to your car, up to 1,000 feet away!
    3. Your car thinks your fob is next to the car and the doors open instantly. Once inside if your car has push button start, they simply push start and drive it away (for safety reasons, your car won't stop until they manually stop the car).

    It's that easy for them, unless your fob is protected. Buy a FobGuard® security pouch today and get protected today.

    You don't need to put your car keys in your freezer, but you do need to protect your keys with our keyless entry fob "faraday cage".

    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® security pouches are manufactured from the highest quality materials. A double layer of German military grade ultra high specification conductive silver/copper/nickel material is first stitched together. Then we wrap the faraday cage in a further layer of tough 400 denier sports nylon to protect it from daily wear and tear. Finally the pouch is sealed using a unique hook and loop closure made using silver. Our uncompromising design ensures your device is completely enveloped inside a true "faraday cage" with unparalleled shielding performance.

    Each layer of the material we use 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. We use multiple layers for increased performance giving you up to 100dB of attenuation exactly where you need it.
