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?

They aren’t. Even Car keys aren’t unique. Back in the day, I had 2 friends who both owned a Geo Metra. One day friend A left my house and realized 10 minutes later that he was driving friend B’s car. Both of their cars had the same jey for the ignition but oddly their keys didn’t work for the other car’s doors.
