Lever vs. Pin Tumbler Locks

Postby MechEng » 13 Oct 2010 12:03

Being an almost mechanical engineer (I really like mechanical things - go figure) locks are something that I have always had interest in and I was wondering why do we have Pin/Tumbler locks on our homes rather than Lever locks? Having seen some nifty warding designs, ratcheting levers, and a host of other lever lock security features they seem pretty secure. IF everyone on this forum is capable of picking the former, I think it would be safe to say that not nearly as many can successfully manipulate a lever lock (needing special tools and all). Is this only because of the popularity of the pin/tumbler? Also, from a design perspective a pin/tumbler, in my eyes, would be far easier to implement than a lever lock due to the mechanism by which the lever lock works so that is one reason I can come up with for the use of the pin/tumbler design.

I think one of the reasons that pin tumbler locks took off may be because of the high cost of reproducing some warded lever locks and duplicate keys.

The convenience factor of the modern pin tumbler method has enabled many more products to be produced at much cheaper prices and allowed many more people to provide key cutting services.

Is the the trade better for it? Perhaps or perhaps not.

In the desire to produce a more modern system, engineers have chosen to forego quality with quantity.

Similarly, it is significantly cheaper to produce products from cast aluminium (die cast) than from steel and while most steel components will have a longer life, potential profits will be lower because manufacturers will sell less often.

It's a viscious circle, all this business decision making that interferes with product quality.

i think some of us enjoy lever locks quite a bit, and have made a few tools in our time to manipulate these for the sake of sport. i for one have lever locks on my house; however not in use, the building is rather old and these locks have all since been gutted or ceased up. but i would agree that cost of manufacturing and maintenance of pin tumblers is lower, and the design is more modern and compact. i'm assuming, one day, with the decline of civilization we'll need to move back toward lever locks, as they will be easier to produce by the blacksmiths in our communes we'll be living in and warming ourselves up so we have the strength to ward of cannibals and zombies...but that's just a theory.
