Vehicle Relay Equipment: Complete Information

What is a Car Relay Attack System?

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

Attack equipment are primarily used by security researchers to evaluate vulnerabilities in smart key technology.

How Does a Relay Attack System Work?

The relay system operates using two separate units that communicate:

First device is placed near the car key fob (in building)
Second device is placed near the automobile
Primary unit detects the communication from the key fob
The signal is sent to second device via data transmission
Unit 2 broadcasts the code to the car
The automobile believes the key is close and unlocks
