Car Relay Attack System: Everything You Need to Know

What is a Car Relay Attack System?

A relay equipment is a two-part equipment that extends the transmission between a vehicle remote and the vehicle. This technology uses two devices working simultaneously to relay communications over greater distances.

Relay devices are primarily used by automotive professionals to evaluate security flaws in smart key technology.

How Does a Relay Attack Device Work?

The attack device works using paired devices that coordinate:

1. Primary unit is placed near the car key fob (at home)
2. Unit 2 is placed near the target vehicle
3. First device captures the communication from the key fob
4. The transmission is sent to second device via wireless connection
5. Secondary unit sends the code to the automobile
6. The vehicle thinks the remote is nearby and grants access
