Express Mode Elevator
Express Trick 1
Press the floor button and the close button at the same time for 5-6 seconds and the elevator will be in express mode. This will also skip any stops and go directly to your floor. This was successful on Dover and Otis elevators. It supposed to work on most Otis models except 1992, the Dover Elevators EL546 and EL0D862, and most Desert models.
Express Trick 2
Pressing and holding a floor continuously in some models might put the elevator in express mode on some select models. However, there is a caveat to this. The option must be turned on in software of the elevator. Older models have this turned on by default, but newer models have this option turned off by default.
Deselect a floor
Press a floor in an elevator and the floor is selected. If you made an accident and you want to cancel the floor selection press the floor button twice (after it has already been selected). This will deselect the floor selection on some models and cancel the elevator to make a stop on that floor.
