Vehicle Relay Equipment: Everything You Need to Know

What is a Car Relay Attack System?

A relay equipment is a dual-unit system that bridges the communication between a car key fob and the vehicle. This equipment uses dual units working together to forward transmissions over extended ranges.

Relay devices are primarily used by penetration testers to assess weaknesses in smart key technology.

How Does a Relay Attack Device Work?

The relay system functions using dual components that communicate:

Primary unit is positioned near the key fob (in building)
Secondary unit is placed near the automobile
Primary unit detects the signal from the key fob
The signal is relayed to Unit 2 via data transmission
Secondary unit sends the transmission to the car
The car believes the key fob is nearby and grants access
