This one sounds so easy, we doubted it would work till we tried it ourselves. And we must say it does seem to work.

The big idea is to put the elevator into "express" mode so that it would sweep you directly to the floor you want to go to without stopping on any other floors; extremely useful when you are in a hurry or  want to show off your "hack" skills.

The hack is rather simple, instead of pressing just the "floor" button, press the "door close" and the "floor" button together at the same time. It works on most Otis Elevators (All but the ones made In 1992), Dover (Model Numbers: EL546 And ELOD862) and most Desert Elevators(All, But Model Numbers ELD5433 And ELF3655). Of course, it's hack so your mileage will vary.
