Relay Attack Device: Complete Information

What is a Relay Equipment?

A relay equipment is a dual-unit device that bridges the transmission between a key fob and the vehicle. This technology uses dual units working simultaneously to forward signals over greater distances.

Relay attack systems are typically utilized by automotive professionals to evaluate vulnerabilities in smart key technology.

How Does a Relay Attack Device Work?

The relay system operates using two separate units that coordinate:

Unit 1 is positioned near the key fob (in building)
Unit 2 is positioned near the automobile
Primary unit receives the signal from the car key
The transmission is relayed to secondary unit via data transmission
Unit 2 sends the signal to the vehicle
The vehicle assumes the remote is nearby and grants access
