Key to Vector Sigma bm.JPG

The Key to Vector Sigma in the Beast Machines TV series.

The Key to Vector Sigma was an ancient device that was connected to Vector Sigma and allowed a Transformer to activate the ancient intelligence. It appeared as a small remote with an overdeveloped power circuit and had the ability to control the robotic Centurion droids that remained in the lower levels of Cybertron and defended Vector Sigma.

Apparently, Beta Maxx's vehicle mode can replace it.
