Vehicle Relay Equipment: Full Guide

What is a Car Relay Attack System?

A relay equipment is a dual-unit equipment that relays the communication between a key fob and the vehicle. This system uses two devices working in tandem to transmit communications over extended ranges.

Relay attack systems are primarily used by security researchers to test vulnerabilities in proximity keys.

How Does a Relay Equipment Work?

The attack device works using dual components that work together:

1. Primary unit is positioned near the key fob (at home)
2. Unit 2 is positioned near the car
3. First device captures the signal from the car key
4. The signal is relayed to second device via RF link
5. Unit 2 sends the signal to the vehicle
6. The automobile thinks the key fob is close and unlocks
