Vehicle Relay Equipment: Complete Information

What is a Car Relay Attack System?

A relay equipment is a two-part equipment that extends the transmission between a key fob and the car. This technology uses paired equipment working together to forward signals over long distances.

Relay devices are typically utilized by automotive professionals to test security flaws in keyless entry systems.

How Does a Relay Attack System Work?

The relay system functions using two separate units that coordinate:

1. Primary unit is located near the key fob (at home)
2. Secondary unit is positioned near the car
3. First device captures the communication from the remote
4. The transmission is sent to Unit 2 via wireless connection
5. Second device sends the signal to the vehicle
6. The automobile assumes the key is in proximity and unlocks
