Relay Attack Device: Everything You Need to Know

What is a Relay Attack Device?

A car relay attack system is a paired device that bridges the transmission between a car key fob and the automobile. This equipment uses two devices working together to forward communications over greater distances.

Relay attack systems are commonly employed by automotive professionals to evaluate vulnerabilities in smart key technology.

How Does a Relay Equipment Work?

The relay attack functions using paired devices that coordinate:

Primary unit is placed near the key fob (in building)
Unit 2 is located near the automobile
Unit 1 detects the signal from the remote
The data is relayed to second device via RF link
Second device broadcasts the code to the car
The automobile thinks the key is in proximity and unlocks
