Vehicle Relay Equipment: Full Guide
What is a Relay Attack Device?
A relay equipment is a two-part device that extends the communication between a key fob and the vehicle. This technology uses dual units working in tandem to transmit transmissions over long distances.
Attack equipment are commonly employed by security researchers to test security flaws in smart key technology.
How Does a Relay Attack System Work?
The relay attack operates using paired devices that communicate:
- Unit 1 is positioned near the car key fob (at home)
- Unit 2 is placed near the target vehicle
- Primary unit detects the signal from the remote
- The transmission is sent to secondary unit via wireless connection
- Secondary unit sends the code to the vehicle
- The automobile thinks the key fob is in proximity and unlocks
