Keyless entry cars are convenient — but also vulnerable.
In the last 24 months alone, UK police forces have reported a dramatic rise in relay attacks, where criminals steal vehicles in less than 20 seconds using devices that intercept and amplify your car key’s signal.
No smashed glass.
No broken locks.
No noise.
Just gone.
This has become the number one method of car theft in the UK.
Fortunately, there is a simple, affordable solution: a Faraday key blocker case — like the premium Vantrix Signal Blocking Pouch.
This article breaks down:
• How keyless theft actually works
• Why it’s so common in the UK
• Why your key fob is constantly transmitting
• How Faraday cages block all signals
• The difference between good and bad Faraday pouches
• Signs yours isn’t working
• Why every keyless car owner needs one today
What Is Relay Car Theft?
Relay theft works using two criminals with electronic devices:
-
One stands near your house
-
The other stands next to your car
They use an amplifier to extend your key fob’s signal through walls.
Your car thinks the key is right next to it.
Doors unlock.
Engine starts.
Thieves drive away.
All without touching your key.
Most keyless owners don’t even know their key fob constantly emits a signal — 24/7 — even when lying on a shelf.
Why the UK Is the Global Hotspot
The UK sees more keyless theft than any other European country due to:
• High density neighbourhoods
• More keyless cars per capita
• Common driveway layouts
• Rapid transit routes for stolen cars
• Easy access to relay devices online
Vehicles most targeted include:
• Range Rover models
• BMW
• Mercedes
• Audi
• Ford ST/RS
• Toyota hybrid keyless systems
If your car is keyless, it is at risk — regardless of model.
How Does a Faraday Pouch Stop This?
A Faraday pouch blocks:
✔ Key signals
✔ Relay signals
✔ Amplifiers
✔ RFID communications
✔ NFC readers
✔ WiFi
✔ Bluetooth
✔ 2G / 3G / 4G
It works by surrounding your key with layers of signal-blocking material, isolating the radio waves completely.
Inside the pouch = your key becomes invisible.
The Importance of Using the Correct Pocket
Most pouches have:
• An outer pocket (NOT protected)
• An inner pocket (signal blocking)
If you put the key in the wrong pocket — it will not work.
The Vantrix pouch clearly separates the two pockets and uses:
• Reinforced carbon-fibre design
• High-grade Faraday shielding
• Durable stitched layers
• Inner metal mesh lining
This ensures complete signal isolation.
Signs Your Faraday Pouch Is Low Quality
Cheap pouches fail within weeks because materials degrade.
Warning signs:
✘ Your car unlocks when pouch is near
✘ Contactless card still works inside
✘ Material feels thin or rubbery
✘ No stitching around shielding layer
✘ No inner seal lining
✘ Only one layer of metallic fabric
A good Faraday pouch has:
✔ Multi-layered shielding
✔ Thick carbon-fibre weave
✔ Interior key-chain anchor
✔ Reinforced stitching
✔ A fully sealed inner pocket
Vantrix meets all these requirements — and exceeds them.
Do You Really Need One?
Ask yourself:
• Do you own a keyless entry car?
• Does your key sit near the front door?
• Do you live in an urban/suburban area?
• Does your car stay on a driveway?
• Is your car considered ‘desirable’ by thieves?
• Would you suffer financially/emotionally if it was stolen?
If you answered yes to even ONE of the above, then yes — you absolutely need a Faraday pouch.
How to Properly Test Your Faraday Case
1. Stand next to your car
Place the key inside the inner pocket.
Try opening the door.
It should not unlock.
2. Try contactless payment
Tap the pouch on a payment reader.
It should not register.
3. Check with your smartphone
Try Bluetooth or NFC detection.
It should fail.
If any of these succeed — the pouch is not working.
Additional Security Tips
• Keep your key away from doors and windows
• Use a steering lock for dual protection
• Disable keyless entry (some cars allow this)
• Use a Faraday case for spare keys, too
