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?

Fun fact. There’s many police cars that use the same key. It’s not really restricted and most people can get this key with some effort.
Hell there’s probably less than a dozen different keys that can unlock way more things than you would expect.
