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?

Residential locks are very far from precise pieces of engineering. Close is often close enough. If you have an original unused key around to compare to your daily used key, compare them and you will see what I mean.
