Vehicle Relay Equipment: Complete Information

What is a Car Relay Attack System?

A relay equipment is a paired equipment that extends the communication between a key fob and the car. This system uses paired equipment working simultaneously to relay signals over extended ranges.

Relay devices are typically utilized by security researchers to assess vulnerabilities in proximity keys.

How Does a Relay Equipment Work?

The relay attack functions using paired devices that work together:

1. Unit 1 is located near the key fob (in building)
2. Unit 2 is placed near the car
3. First device captures the communication from the car key
4. The signal is relayed to secondary unit via wireless connection
5. Unit 2 transmits the signal to the car
6. The automobile thinks the key fob is nearby and opens
