Recently moved to a gym that uses padlocks for locking your stuff, they sell them too for an inflated price of 3.5$, jokingly I tried my key on a friend’s lock, and one more random one, of course it didn’t work and it made me curious.
My question is how do factories make all keys/locks different even at these cheap mass produced kinds that are probably sold for 0.5-2$, how is it worth for a factory to “use different patterns” at that price, or how do they do it?

I’m assuming you are referring to standard pin key locks. There are actually a lot of youtube channels that can explain it far better than I, but the basic gist is that you have a cylinder, lock pins, and driver pins. In an industrial mass production environment, you have machines making pins of each size. All the pins are interchangeable, and it really easy to cut keys at separate depths.
