It’s my understanding that mass produced items are all basically the same. If you buy something like a toothbrush, for example, then any other toothbrush from that same assembly line is going to be basically the same and have all the same specs (with the exception with minor defects here and there), because the machinery and process to make any those toothbrushes are all basically the same.
But that can’t be the case with locks and keys. Because if every lock and key were the same then there’d be no point in having them. Anyone could just bought the same key/lock combo could use it to unlock your front door. So all or most keys and locks must be unique. So how are they mass produced in a way that preserves their uniqueness?


LockPickingLawyer, maybe?
There’s another one that popped up pretty recently that almost never uses real locksmithing tools, and just makes a shim out of an aluminium can real quick to pop open a lock. They got Streisand Effect’d by some lock company trying to claim his videos are bullshit becsuse he frequently shows how that particular brand of lock sucks ass.
McNally v Proven Locks
Is probably what you’re talking about. And apparently Proven Locks is mostly a shit show with one ok product and full of “hurrdurr American patriot” marketing.
It’s possible. Sorry I can’t remember the name.
