Why use a Faraday pouch for your keys?
Stops the relay attack at the source
Modern keyfobs broadcast a low-power signal whenever they're within range. Thieves use a relay device to amplify that signal from outside your house to a receiver near your car - and drive off without ever touching the key. Three layers of TitanRF fabric block the signal entirely, so there's nothing to relay.
Works the moment you drop the fob in
No batteries, no app, no pairing. The pouch shields whatever's inside it across all the major wireless bands - RF, Bluetooth, NFC, cellular. Take the fob out to drive, put it back in when you're home. That's the whole routine.
Built to live with your keys, not in a drawer
A pouch only protects the fob when the fob is inside it. Both our keyfob pouches are sized to sit in a handbag, glovebox or jacket pocket without bulk, so dropping the fob in becomes part of the routine instead of a thing you forget. Pick the one that matches how you carry your keys.
The pouch only works while your fob is inside it
Daily-use habits, where in the house to keep it (hint: not by the front door), and what to do with the spare key - the things that decide whether this thing actually saves your car.

Faraday Pouch FAQs
A Faraday pouch is a small bag lined with conductive metallic mesh. Once your key fob is inside and the pouch is sealed, the mesh forms a Faraday cage that blocks the radio signal in both directions. Thieves with relay devices can't pick up the fob's signal, so they can't trick your car into unlocking.
Yes, when they're properly built and sealed. A genuine Faraday pouch tested to MIL-STD-188-125-2 or IEEE 299-2006 will block the radio signal a relay attack relies on. Cheap pouches from marketplace sellers often use thin single-layer linings or have seam gaps that leak signal, so the brand and build matter. You can test any pouch in 30 seconds by trying to unlock your car with the sealed pouch in hand.
The best Faraday bag for car keys in Australia is the one matched to how you use it. If your fob lives in a pocket or handbag during the day, choose a slim, premium-build pouch designed for daily carry. If your keys live by the door at home, a household pouch with a positive flap closure is the better fit. Both styles are stocked at Trust Panda and ship from Sydney.
Drop your fob inside, close the pouch fully, and place it away from external walls and windows. A central drawer or upstairs bedside table is ideal. The pouch only blocks signal while the fob is inside it, so it has to become part of the routine: keys go in the pouch every time you walk in the door, not just at night. Treat the spare key the same way.

Faraday bags can stop working if the conductive lining wears through at high-stress points like seam folds and flap edges, or if the closure stops sealing tightly. Cheap single-layer pouches degrade fastest. Quality pouches use double-layered or reinforced shielding to extend the working life. Test yours every few months by trying to unlock your car with the sealed pouch.

A Faraday pouch and a Faraday box do the same job: enclose your fob in a conductive shell that blocks signal. A pouch is portable, soft, and fits in a drawer or handbag. A box is rigid and lives in one spot. For most households, a pouch is the more practical choice because the cage only works while the fob is inside, so portability matters.
Yes, and you should. Put your fob inside, seal the pouch fully, then walk up to your locked car with the pouch in your hand. If the car doesn't unlock and the engine won't start with the pouch closed, the cage is working. Open the pouch and try again. The car should respond instantly. Repeat the test every few months.
If your car has keyless entry or push-button start, yes. Relay theft is now one of the fastest-growing methods of vehicle theft in Australia, with Victoria Police estimating 20 per cent of stolen cars in the state are taken using electronic key-signal hijacking. The pouch costs about the same as a tank of fuel and removes the relay attack vector entirely.
Most car key fobs in Australia broadcast on 315 MHz, 433 MHz, or 868 MHz, depending on the manufacturer and model. Newer cars also use Bluetooth Low Energy (around 2.4 GHz) and Ultra-Wideband for proximity detection. Quality Faraday pouches are rated to block all of these frequencies plus Wi-Fi, GPS, and cellular, so they cover every fob currently on the road.
Most Faraday key fob pouches are sized for a single fob, with some larger styles holding a fob plus a couple of cards. Check the product details above for the specific size and capacity of this pouch. Most Australian households have a primary fob and a spare, and thieves don't care which one they relay, so plan to cover both.
