Elevator 2.0

We have elevators in our house. They change it funny - swearing, noisy. Periodically, they have something in the mine that flies down, with an eerie crash hitting the walls. It turns out louder than when throwing bottles into the garbage can. But I'm not talking about that ...

I'm talking about hidden opportunities. Are they in elevators? Often there are secret commands, by typing which on the phone keypad, you can get additional functions, learn something about the phone, etc.

So it became interesting to me, is it possible to type some secret command on the elevator buttons, for example, to change its speed, or is it nonsense and the elevator cannot be reflashed via buttons ... Strange such reflections.
