Vehicle Relay Equipment: Everything You Need to Know

What is a Car Relay Attack System?

A relay equipment is a dual-unit system that extends the communication between a car key fob and the vehicle. This technology uses paired equipment working simultaneously to relay transmissions over long distances.

Relay attack systems are primarily used by automotive professionals to assess security flaws in proximity keys.

How Does a Relay Equipment Work?

The attack device functions using paired devices that communicate:

First device is positioned near the remote key (inside house)
Second device is placed near the automobile
Primary unit receives the communication from the car key
The signal is relayed to secondary unit via data transmission
Secondary unit sends the code to the vehicle
The car thinks the key fob is close and opens
