Relay Attack Device: Full Guide

What is a Relay Equipment?

A car relay attack system is a paired device that relays the transmission between a vehicle remote and the vehicle. This system uses paired equipment working together to relay signals over extended ranges.

Relay attack systems are primarily used by automotive professionals to test security flaws in smart key technology.

How Does a Relay Equipment Work?

The attack device functions using paired devices that communicate:

Primary unit is positioned near the remote key (in building)
Second device is placed near the car
First device captures the signal from the key fob
The transmission is transmitted to Unit 2 via RF link
Unit 2 sends the signal to the automobile
The car assumes the key fob is in proximity and opens
