Whats the name of this movie?

I remember this movie playing on the scifi channel when i was a kid, probably 2003-2006, where 6 kids go to this small town to vacation at this house that one of the kid's uncle owns. They were in college I believe. It was a black guy, a red head girl, a couple, and then a brunette and the main character. When they get to the house there's all this metal around it, like above the door. They find a jar with an aliens hand in it in the basement and it twitches. The red head goes missing first, then the black guy, then the aliens start beaming into the house, and one of the guys is halfway standing on the beam and is cut in half down the middle. Finally the last three kids escape in a truck. But thats all I can recall. Please help me find this movie. It'd be greatly appreciated.
