Vehicle Relay Equipment: Complete Information

What is a Relay Attack Device?

A car relay attack system is a dual-unit device that extends the signal between a car key fob and the automobile. This technology uses dual units working together to relay communications over long distances.

Relay devices are commonly employed by security researchers to assess vulnerabilities in keyless entry systems.

How Does a Relay Attack Device Work?

The relay system works using paired devices that coordinate:

Primary unit is located near the remote key (at home)
Second device is positioned near the car
Unit 1 detects the transmission from the key fob
The transmission is transmitted to Unit 2 via data transmission
Unit 2 broadcasts the transmission to the automobile
The car believes the key is nearby and grants access
