if you listen to the housing of the lock with a listening device whilste you are turning the handle then you can here when you press the right button

NO YOU CANT!

The Unican locks will turn the first 'rotor', then a second key press will turn the second AND first, and so on.

You cannot know if they are the correct buttons until the very last press, when they all spin into the correct location and unlock.

There is a way to find the combination by feel using force on the lever and the buttons...I don't know if we can put that here so I'll leave it out. Under the Door tool is much easier though!

I think thats a different lock you're thinking of.
