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?
New locks usually tell you what key set they are on the package… So you can buy multiple of the same lock to rekey an entire house.
While the locks can be rekeyed to thousands of options, the prepackaged options will only be a few sets.
Yeah, and I think when homes are manufactured they just buy sets in bulk. One would think they would rekey them, but I guess not. I mean, even if they were, you should rekey your locks in any new home anyways - but even I fell victim to that because despite knowing this, no one ever does, and it happened twice. You think one would learn.
They won’t bother rekeying, but they normally are buying enough that different sets are inevitable even if they don’t actively try.
