Vehicle Relay Equipment: Full Guide

What is a Car Relay Attack System?

A relay equipment is a paired device that relays the signal between a vehicle remote and the car. This equipment uses paired equipment working together to relay signals over greater distances.

Attack equipment are commonly employed by security researchers to assess vulnerabilities in keyless entry systems.

How Does a Relay Attack Device Work?

The relay system operates using dual components that work together:

1. Unit 1 is placed near the key fob (at home)
2. Secondary unit is positioned near the automobile
3. Unit 1 captures the transmission from the key fob
4. The data is transmitted to Unit 2 via RF link
5. Unit 2 sends the code to the car
6. The car assumes the remote is in proximity and opens
