Faraday Key Signal Blocking, Waterproof Cage RFID Key Fob Blocking Protection, Pack of 2, Carbon Fiber Texture
Modern keyless fobs carry identification chips that pick up radio signals sent out by the car. The vehicle recognises the fob when it’s in range and unlocks the doors. Keyless ignition systems work in the same way, enabling cars to start when the key fob is detected in the cabin. This is where the Faraday Key Signal Blocking comes in, to provide protection against any potential theft.
Criminals can exploit this via a wireless relay attack. Using a radio frequency relay booster, it’s possible to pick up and then transmit a key-fob signal to trick the car into thinking a fob is present. This enables entry and theft from the cabin or boot and, in the case of keyless ignition systems, theft of the vehicle itself.
Thanks to its 100% signal jamming capability, this faraday bag completely isolates your fob to make such attacks impossible, giving you complete peace of mind as a protector against data loss.
How does the faraday bags work?
This faraday bag makes your car safe by stopping signals being sent or received by your key fob or any other device containing data. Remove your key from the wallet and signal reception is restored immediately, enabling normal usage.
