Vehicle Relay Equipment: Complete Information

What is a Car Relay Attack System?

A relay attack device is a two-part equipment that bridges the signal between a key fob and the vehicle. This technology uses two devices working in tandem to relay communications over long distances.

Relay devices are primarily used by automotive professionals to test security flaws in smart key technology.

How Does a Relay Attack Device Work?

The attack device functions using paired devices that coordinate:

Unit 1 is placed near the remote key (inside house)
Secondary unit is placed near the automobile
Primary unit receives the communication from the key fob
The transmission is transmitted to second device via wireless connection
Secondary unit broadcasts the transmission to the automobile
The vehicle assumes the key fob is in proximity and opens
