How Thieves Steal CarsWithout Touching a Key
Relay theft is the fastest-growing method of vehicle theft in the UK. Understanding how it works is the first step to protecting your car.
Relay Theft: How It Works
Two thieves, two devices, one car. Here's the attack that takes under 60 seconds.
Thief A Scans Your Home
One thief stands near your front door with a relay amplifier. It captures the radio signal your key fob constantly broadcasts — even through walls and doors.
Signal Relayed to Your Car
The captured signal is transmitted wirelessly to a second device held by Thief B, standing next to your vehicle in the driveway or street.
Car Unlocks & Engine Starts
Your car detects the relayed signal and thinks the real key is present. Doors unlock, push-button start engages, and the thieves drive away — no alarm, no damage.

A Faraday Cage for Your Key Fob
Our signal blocker pouch uses the same principle discovered by Michael Faraday in 1836: a conductive enclosure that blocks electromagnetic fields. When your key fob is inside, no radio signal can enter or leave.
Blocks All Frequencies
RFID (125kHz), NFC (13.56MHz), Bluetooth (2.4GHz), UHF (315/433MHz), and keyless entry systems — all signals are stopped.
Dual-Layer Construction
An outer durable fabric layer and an inner metallic Faraday lining create complete signal isolation. Independently tested.
Instant & Passive
No batteries, no charging, no setup. Just zip the pouch closed and your key fob is invisible to relay devices.

Test It Yourself — Right Now
You don't need to take our word for it. Here are three simple tests you can do at home.
The Door Handle Test
Put your key in the pouch, zip it closed, and press it against your car door handle. If your car has keyless entry and the door stays locked — the signal is blocked.
The Start Button Test
Sit in your car with the key inside the closed pouch. Press the push-to-start button. If the dashboard says 'Key Not Detected' — the pouch is working.
The Phone Test
Place your phone inside the pouch, zip it closed, and have someone call you. If the call doesn't go through — the Faraday shield is intact.
