I am looking for a 80s movie a lad bult a robot then started to kill people. But then his friend died so he took out the chip out of the robot then he tranplanted it in he's friend's brain and bourt her back to life then she started to kill people. Can some one tell me the name of the movie. Thank you

Sounds like Deadly Friend from 1986.

Deadly Friend by Wes Craven starring Kristy Swanson. Many of his movies involved bringing people back to life: Serpent and the Rainbow, Shocker, Nightmare on Elm Street.
