Vehicle Relay Equipment: Full Guide

What is a Relay Equipment?

A car relay attack system is a dual-unit device that bridges the signal between a key fob and the car. This equipment uses paired equipment working in tandem to forward signals over extended ranges.

Attack equipment are typically utilized by penetration testers to evaluate vulnerabilities in smart key technology.

How Does a Relay Attack System Work?

The relay system works using two separate units that coordinate:

Unit 1 is located near the key fob (at home)
Second device is located near the target vehicle
Primary unit receives the signal from the remote
The data is relayed to Unit 2 via wireless connection
Secondary unit sends the code to the car
The automobile believes the key fob is nearby and unlocks
