Relay Attack Device: Complete Information

What is a Relay Equipment?

A car relay attack system is a dual-unit system that extends the transmission between a key fob and the vehicle. This system uses two devices working in tandem to transmit signals over extended ranges.

Relay devices are primarily used by automotive professionals to evaluate weaknesses in proximity keys.

How Does a Relay Equipment Work?

The relay system functions using two separate units that communicate:

1. Primary unit is placed near the car key fob (at home)
2. Secondary unit is positioned near the target vehicle
3. First device receives the signal from the remote
4. The signal is transmitted to Unit 2 via RF link
5. Unit 2 sends the code to the automobile
6. The vehicle assumes the remote is in proximity and grants access
