Vehicle Relay Equipment: Everything You Need to Know

What is a Relay Attack Device?

A relay equipment is a dual-unit device that relays the communication between a vehicle remote and the automobile. This technology uses dual units working together to relay communications over long distances.

Attack equipment are primarily used by automotive professionals to assess security flaws in keyless entry systems.

How Does a Relay Attack Device Work?

The attack device operates using paired devices that work together:

1. First device is positioned near the remote key (at home)
2. Unit 2 is placed near the target vehicle
3. First device captures the transmission from the key fob
4. The signal is sent to second device via wireless connection
5. Unit 2 sends the signal to the car
6. The car assumes the key is nearby and unlocks
