Vehicle Relay Equipment: Everything You Need to Know

What is a Relay Equipment?

A relay attack device is a paired system that bridges the signal between a vehicle remote and the vehicle. This equipment uses dual units working in tandem to transmit signals over extended ranges.

Relay devices are primarily used by security researchers to assess vulnerabilities in smart key technology.

How Does a Relay Attack Device Work?

The relay system works using dual components that work together:

Primary unit is placed near the key fob (in building)
Unit 2 is placed near the target vehicle
Unit 1 detects the communication from the key fob
The signal is transmitted to second device via RF link
Unit 2 transmits the code to the car
The car believes the remote is nearby and grants access
