They probably save a bit more than a dime a lock.
The one piece design uses the same knob for the inside and outside. As well as being easier to produce it is also easier to finish. CY: Oh, same in and out? I'd not noticed.
The advantage to the locksmith is you don't have to remove the lock from the door to rekey it CY: Yep, unlike Kwikkie.
and you can offer this as a cost saving option where you have other Schlage locks in the building. It is not really any big deal to service the cylinder, it is just different. CY: As for me, I don't like em.
Of course I have many different views on things. The last shop I worked at everyone there had a stark raving fear of Almont padlocks, preferring the made in China Abus. I could re-key them as fast or faster, and I never had one fail in use, and I can't say the same about the Abus. CY: Glad the worked fo ryou.
