Car Relay Attack System: Everything You Need to Know
What is a Relay Attack Device?
A car relay attack system is a two-part equipment that extends the signal between a key fob and the vehicle. This equipment uses dual units working in tandem to forward transmissions over extended ranges.
Relay devices are primarily used by automotive professionals to test security flaws in keyless entry systems.
How Does a Relay Equipment Work?
The relay attack operates using dual components that work together:
- First device is positioned near the remote key (inside house)
- Secondary unit is placed near the target vehicle
- First device detects the transmission from the car key
- The data is sent to secondary unit via RF link
- Secondary unit transmits the transmission to the car
- The car believes the key fob is nearby and unlocks
