If you have a car with vulnerable keyless entry, anyone can open your vehicle and simply drive it away
Using the signal emitted from your own key fob, thieves can open and operate your car without breaking into it leaving no trace. Try explaining that to your insurance company.
It’s called a “signal amplification attack”. Here’s how it works:
- You think your fob is safe in your pocket or on your kitchen bench while you are shopping, working, or sleeping
- A thief comes close to your fob (even through the walls of your house) and re-transmits that signal up to 1,000 feet away to their friend who is next to your car
- Your car doors open instantly and if it has a push button start they can simply drive it away
FobGuard® security pouches ensure you don’t become a victim of this crime. Our patent pending “Military Spec” FobGuard® security pouch can save you thousands of dollars in uninsurable contents loss. Just put your keyless entry fobs inside a FobGuard® security pouch when you’re not using them and your car is protected.
There is no other solution except to put your key fob inside a faraday cage you can trust to protect you, and FobGuard® is the best there is. Buy a FobGuard® security pouch today for each of your fobs.

Help put the genie back in the bag
Finally Found the Right Solution To My Ongoing FOB Security Problem! Great product, and worth the price for security.
⭐⭐⭐⭐⭐
Great, quality product
We tested them right next to the car and it still blocked the signal and wouldn’t unlock the car. Great product!
⭐⭐⭐⭐⭐
Great
It works well, easy to use. I’d buy it again
⭐⭐⭐⭐⭐
Very effective
Without one of these guards I was able to open my car from inside my house easily. But I can’t even open the door standing next to the car if my remote is inside.
⭐⭐⭐⭐⭐
Love it so far; ordering two more!
Will keep this item in mind for future gifts for other friends and family with wireless key fobs.
⭐⭐⭐⭐⭐
Perfect
Works exactly as advertised and fits easily in front pocket. Having this gives me a much higher comfort level.
⭐⭐⭐⭐⭐
Awesome security pouch!
The FobGuard pouch works perfectly. It really does shield the signal as stated. No more worries about car thieves accessing the signal with the equipment they use. Will recommend this product to all family and friends, thanks for making this available.
⭐⭐⭐⭐⭐
It really works!
I feel confident that there will be no transmission of my fob’s information into the wrong hands. While my fob is secured in the pouch, my cars will not unlock until I remove it. Very cool. I need two more!
⭐⭐⭐⭐⭐
Fabulous FobGuard
Love the product. Only suggestion for improvement would be to make the inside fabric loop slightly bigger/longer, as this would make it much easier to attach the fob.
