Vehicle Relay Equipment: Full Guide

What is a Relay Equipment?

A relay attack device is a paired equipment that bridges the communication between a vehicle remote and the vehicle. This equipment uses paired equipment working in tandem to transmit communications over extended ranges.

Relay attack systems are primarily used by automotive professionals to assess weaknesses in smart key technology.

How Does a Relay Equipment Work?

The attack device works using paired devices that work together:

First device is positioned near the key fob (in building)
Secondary unit is positioned near the car
Primary unit captures the signal from the car key
The transmission is sent to Unit 2 via data transmission
Second device sends the signal to the car
The car believes the key is nearby and unlocks
