Awesome quality product

— Gary H. Cambridge, UK
Does EXACTLY what everyone has said

Had a friend that just bought a 23' TRX.
Within 2 weeks it was stolen here in Baton Florida. I heard about this company through YouTube fortunately.
Placed my order and got a notification that it was shipped, that SAME day (Very unusual)
Package arrived in 3 days, and to my surprise this thing WORKS.
It's very sturdy and has a magnetic top that closes with your fob inside, makes a cool sound too.

— Thomas M. Baton, FL
Hands down BEST customer service that I've ever seen

Just want to say that this customer service team deserves 10 stars alone. I ordered a RFID blocker shell but they were out of stock. Customer service called me immediately and told me that my order would be delayed a little bit. They automatically bumped my order to priority shipping and gave me a big discount for my next order. Most companies these days don't tell you anything until you contact them, even then it takes forever to get a response. They kept me updated until my package arrived. As for the product, it was top quality and came in really nice packaging. Even though it was delayed the whole experience was top notch and I will be telling everyone I know and ordering more for family members!

— Melanie, London
Wow... actually does what it says

I bought based on another reviewer saying the car would not start while their key was in the case, and that is 100% true. Top quality product and got here pretty quick.

— Salvador H. Northport, N.Y.

Myths & Frequently Asked Questions

What Is RFID Signal Hacking? How Can My Car Be Stolen Through My Key Fob?

RFID stands for radio frequency identification. Your key fob utilizes a radio-frequency transponder to communicate with the door locks, but it uses infrared to communicate with the engine's immobilizer system. By using signal relay devices carjackers can open and operate your car without setting off your car alarm.

By using signal relay devices carjackers can open and operate your car without setting off your car alarm.

How Much Range Is Required For RFID Signal Hacks To Work?

The most common signal boosting amplifier's will work from 20 - 30 feet away. Higher end technology will work from 300ft - 1,000ft.

Once I Receive My Hyperion RFID Signal Blocker, How Do I Know It Works?

1. Enter your car with your fob and Juggernaut shell.

2. Put your fob all the way in your shell and close it.

3. Try to start your car.

The dash will read "Key not detected" and your car will not start.

If I Put My Key Fob Away From My Car (i.e. inside my house), Will It Prevent My Signal From Being Stolen?

Unfortunately, no.

The signal sent to your car from inside of your house (or from inside of a store) can be stolen and relayed back to thieves the same way.

Our RFID signal blocking key fob products are constructed of signal-isolating, static dissipative polyethylene lining. They prevent RFID, NFC, Bluetooth, GPS/SatNav networks, 2,3, and 46 mobile phone WiFi connectivity- stopping all frequency signals that are sent or received by your cars fob system.

If I Don’t Hit My Key Fob Buttons, They Can’t Steal My Signal Right?

Unfortunately, no.
The signal can be stolen without pressing a button. The car communicates with the fob all the time when the battery is in. That is how it knows when you are close.

I Heard My Key Fob Does Communicate Periodically, But It Does Not Communicate The "unlock, lock, engine start" Communications Continuously?

You don't need the unlock info on a car with push button start. All you need is for the car to think your remote is near. That's what the thieves are copying.

Do I Need To Install An App Or Any Software?

Nope! No software, app, or battery needed. Just place your key fob inside of our shell lined with polyethylene and you're good to go!

If I Don't Have A Push Start Button, But I Only Have A Keyless Entry Alarm, Can My Signal Get Stolen?

Even with keyless entry your car can still be "tricked" into being open. Your personal belongings are still at risk once they relay your signal and hack in.

If The Sleeve Gets Wet Does It Still Work?

YES!! Great question! During the testing phase this was one of the experiments that we tried! The sleeve lining is actually, VERY water absorbent. Just don't place it in the bottom of a pool, haven't tested that! (Yet)
