Most keyless fobs have an identification chip that picks up radio signals from the car. The vehicle recognizes the key fob within range and unlocks the doors. A keyless ignition system works the same way - enabling the car to start when a key fob is detected in the car. Criminals can exploit this through wireless relay attacks. Using an RF relay booster, a key fob signal can be picked up and transmitted to trick the car into thinking it is present. This enables access and theft from the cab or trunk - in the case of a keyless ignition system, the vehicle itself is also stolen. Thanks to its 100% signal jamming capability, the Bovrou Faraday Box completely isolates your fob, making such attacks impossible. In addition to blocking the car key signal, you can also block mobile phone signals, WiFi, Bluetooth, GPS, RFID, NFC and other signals!
