Relay Attack Device: Everything You Need to Know

What is a Car Relay Attack System?

A relay equipment is a paired system that relays the transmission between a vehicle remote and the automobile. This technology uses paired equipment working simultaneously to transmit communications over extended ranges.

Relay devices are typically utilized by security researchers to test weaknesses in smart key technology.

How Does a Relay Attack Device Work?

The attack device operates using dual components that coordinate:

  1. Unit 1 is placed near the car key fob (at home)
  2. Second device is located near the car
  3. Primary unit receives the transmission from the remote
  4. The transmission is relayed to secondary unit via RF link
  5. Secondary unit sends the transmission to the car
  6. The car believes the key is nearby and opens
