Teenage Girl With Robot Brain Kills Friends

There was an 80's movie about kids that steal a robot from a lab, take it's processor chip (brain) and put it into one of their friends who they accidentally kill.

The revived friend with the robot's brain goes on a rampage and begins to kill the friends.

I remember it really creeped me out when I was younger, but I've never seen it again. Does anyone know the movie I'm talking about?
