Relay Attack Device: Complete Information

What is a Car Relay Attack System?

A car relay attack system is a paired system that relays the communication between a key fob and the vehicle. This technology uses paired equipment working simultaneously to forward transmissions over greater distances.

Relay devices are typically utilized by penetration testers to assess weaknesses in smart key technology.

How Does a Relay Equipment Work?

The relay system functions using two separate units that work together:

Primary unit is positioned near the remote key (at home)
Secondary unit is placed near the car
First device detects the signal from the key fob
The signal is sent to second device via RF link
Second device broadcasts the transmission to the automobile
The vehicle assumes the remote is nearby and unlocks
