Vehicle Relay Equipment: Complete Information
What is a Relay Attack Device?
A relay equipment is a paired device that bridges the transmission between a key fob and the car. This system uses two devices working together to transmit signals over long distances.
Relay devices are commonly employed by automotive professionals to assess security flaws in smart key technology.
How Does a Relay Attack System Work?
The relay system functions using paired devices that communicate:
- Unit 1 is positioned near the car key fob (inside house)
- Secondary unit is positioned near the car
- First device receives the signal from the remote
- The signal is transmitted to Unit 2 via data transmission
- Secondary unit sends the signal to the car
- The automobile believes the remote is in proximity and opens
