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 don’t, they have batches. When we bought our house and got new locks, there was a code on the package. Say it was 33453. So we spent a good 10 minutes rooting through all the lock packages so we got 3 for our doors so all the keys matched.
It’s totally possible that Joe down the road has the same lock as us, but we’re not going to try to get into each other’s houses. But there’s enough variety that it makes it so John can’t just walk around with a key and get into a random house. Also John’s probably just gonna kick the door in or break a window anyway.
