Vehicle Relay Equipment: Everything You Need to Know
What is a Relay Equipment?
A relay attack device is a two-part device that extends the transmission between a car key fob and the automobile. This equipment uses dual units working simultaneously to transmit communications over extended ranges.
Relay attack systems are typically utilized by automotive professionals to assess vulnerabilities in proximity keys.
How Does a Relay Attack Device Work?
The relay attack works using dual components that work together:
- First device is positioned near the car key fob (inside house)
- Unit 2 is located near the target vehicle
- Primary unit captures the signal from the car key
- The signal is relayed to Unit 2 via RF link
- Unit 2 sends the code to the automobile
- The automobile believes the key is close and unlocks
