How are all locks/keys different when mass produced?

2.32K viewsEngineeringOther

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?

Watch some videos by the Lock Picking Lawyer on YouTube.

You’d be surprised how insecure almost all common locks are. Some of the major lock manufacturers are egregiously bad.

So to answer your question, they aren’t and they aren’t all that secure even if they were.
