Rising auto theft due to signal interception is increasingly common because thieves are using devices to exploit the wireless communication between key fobs and vehicles. These devices, known as relay attacks, amplify and capture the signal from key fobs, allowing thieves to unlock and start vehicles without needing the actual key fob.
In summary, RFID blocking key holders work by creating a shield around the key fob that blocks radio signals, preventing thieves from using relay attacks to intercept and replicate the key fob’s signal. This simple yet effective measure helps to protect vehicles from unauthorized access and theft.
