My best friend just made a copy of our apartment key. She was pretty sure the machine messed up because the key was cut very different from the original. To her surprise, it still opened our front door. How is this possible?
Assuming it may have something to do with the height or order of how the pins in the lock open/fall?

A lock that has two pins can still be opened by a key with 5 teeth so long as two of those teeth are correctly spaced and the correct height to move those pins in the right place. The other 3 teeth do not matter. The appearance of the keys can be different, but those two keys are probably the same where it matters if it unlocks the door.
