Vehicle Relay Equipment: Complete Information

What is a Relay Equipment?

A car relay attack system is a two-part system that extends the transmission between a key fob and the automobile. This system uses paired equipment working in tandem to relay signals over long distances.

Relay attack systems are typically utilized by automotive professionals to test vulnerabilities in smart key technology.

How Does a Relay Equipment Work?

The relay system operates using dual components that work together:

1. Primary unit is placed near the remote key (inside house)
2. Secondary unit is placed near the automobile
3. First device detects the signal from the remote
4. The data is transmitted to Unit 2 via data transmission
5. Unit 2 transmits the signal to the automobile
6. The car assumes the remote is in proximity and grants access
