Signal-Blocking Faraday Pouch
How do I know it's actually working? (The 5-Second Test)
How do I know it's actually working? (The 5-Second Test)
The 5-Second Car-Door Test — your own car is the proof:
1. Seal your key fob inside the pouch and close it fully.
2. Walk to your driver's door and pull the handle the way you always do.
3. If the car stays locked, the signal isn't getting out. Take the fob out and it unlocks instantly.
Retest once a month. That five seconds is the whole point — you never have to take our word for it.
What about the cheaper Faraday bags I see on Amazon?
What about the cheaper Faraday bags I see on Amazon?
The price gap on Amazon usually comes down to two things: how much conductive material is in the lining, and how the pouch seals.
Low-cost pouches typically save on both — a single thin shielding layer and a closure that does not maintain a continuous seal through daily use.
The KeyShield Pouch is built the opposite way: multi-layer shielding inside, roll-top closure outside, full overlap when sealed.
Backed by a 30-Day Test Guarantee and a 1-Year Warranty against material failure. Test it yourself the day it arrives. If it does not perform as described, send it back.
How long does the Faraday shielding last?
How long does the Faraday shielding last?
With normal indoor use, the shielding lasts multiple years. Physical wear comes from repeated flexing of the fabric and stress on the closure — not from the shielding fading on its own.
Retest with the 5-Second Test monthly. If it ever fails, the 1-Year Warranty covers material failure — we replace it.
30-Day Guarantee & 1-Year Warranty
30-Day Guarantee & 1-Year Warranty
30-Day Test Guarantee: Try it. Run the 5-Second Test. If it does not work as described, or you change your mind inside 30 days, email contact@supphoria.com for a full refund.
1-Year Warranty: Material defects covered for a full year from purchase. If the shielding fails the 5-Second Test under normal use within the warranty period, we replace it.

Ran the gold-standard test the day it arrived. Stood next to my car door with the key sealed in the pouch — the car didn't detect a thing. Took it out, the door unlocked instantly. That's all the proof I needed.
-
Tried two of the cheap fob pouches — both stopped blocking inside a month. Tested this one at the car the day it arrived: fob sealed, the door wouldn't open. Still working three months on. Worth paying for the build that lasts.
-
Same spot every night. Keys in the pouch, seal closes. I always know where the keys are, and I know the signal isn't reaching anything outside. That's all I wanted.
While You Sleep
Your key fob keeps relaying signal from inside your house. Every night, while you sleep, that signal can be picked up and relayed to the car in your driveway.
The KeyShield Pouch shuts it down with the Silence Seal™ — seal the fob, the relay signal goes silent, and you prove it in 5 seconds at your own door. The only thing that reaches your car is you.

Key In Pouch. Car Won't Unlock.
Drag the slider: key fob out, the car wakes up. Fob sealed in the KeyShield Pouch, the door stays shut. That's the Silence Seal™ — the 5-second test you can run yourself.

What Our Customers are Saying
-
Keyless Car Owner — Robert S.
"I stood right next to my car door with the key sealed in the bag, and the car didn't detect it at all. As soon as I took the key out, it worked instantly."
-
Parent — Richard H.
"Pouch give me so much peace of mind. The keys go in every night."
-
Two-Car Household — Linda T.
"One pouch by the door for my fob, one for my husband's. Both cars sit in the driveway overnight — now neither key is reachable."
-
Architect — Tom W.
"I have a Faraday for the main keys and the spares have their own pouches. The 'sleeping key thing' probably makes it a redundant precaution, but I believe in belt and braces, it promotes good habits. We always know where the keys are."
Seal It. Silence It. Test It.
The Silence Seal™
1. Seal — the fob goes in, the closure folds fully shut
2. Silence — the relay signal can't reach the car
3. Verify — the 5-second car-door test proves it
Be Truly Silent
Your key fob never stops listening for the car. That's how keyless entry works — a constant low-power handshake, even while it sits in a bowl by the front door.
Thieves don't pick a lock. They catch that signal, relay it to the driveway, and the car opens for them.
The KeyShield Pouch ends the handshake the moment the closure rolls shut. Sealed, the fob goes silent — and the car can't be told to open.

A Simple, Verifiable Method
"Relay attacks work by amplifying the fob's low-power signal — extending its range from inside your house to your driveway.
A properly sealed Faraday bag interrupts the signal before it leaves the bag.
Verify it yourself: seal the fob, walk to your car, pull the handle. If the door doesn't unlock, the shielding is working."

Stop Wondering. Start Testing.
Your key fob shouldn't be reachable from inside your own house.
Your car shouldn't open for someone holding an antenna in the street.
And you shouldn't have to take anyone's word that a pouch works.
Seal the fob. Walk to your door. Pull the handle. If the car stays shut, the Silence Seal™ is doing its job — and the 30-Day Test Guarantee means if it doesn't pass in your own hands, you send it back.
