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?

there’s literally a thing where if you see some one getting a lock, chances are the ones on the shelf with it are keyed identically so you could just buy one of them and let yourself into their house later. there’s a code on the box that tells you exactly what key it uses even.
