Walk up trip my xj8 2006 and turn the key to unlock it and it sounds like I'm being shot at by an automatic. Then I finally make it in the car safely start the car out it in reverse, and they start shooting again and the inside lock look like a victim of the exercist... Jumping in and out on it's on... So finally I try to drive off to safety, and here come Linda Blaire with an automatic again. Someone please help

 

Are you saying that the door locks and unlocks by itself? Rapidly? What happens when you try to lock or unlock with the key fob?
