Vehicle Relay Equipment: Everything You Need to Know

What is a Car Relay Attack System?

A car relay attack system is a dual-unit system that relays the signal between a key fob and the vehicle. This technology uses dual units working together to relay transmissions over extended ranges.

Relay devices are commonly employed by security researchers to evaluate weaknesses in proximity keys.

How Does a Relay Equipment Work?

The attack device functions using dual components that work together:

Unit 1 is located near the key fob (inside house)
Secondary unit is placed near the car
Unit 1 captures the transmission from the key fob
The signal is sent to second device via RF link
Second device sends the code to the vehicle
The car thinks the key is nearby and opens
