New Door Lock

[RobertKB]

Back door lock broke so I went to get a new one. You cannot buy the old style like on the right. I literally looked all over town. I finally broke down and bought the Rube Goldberg mess on the left. Why do they have to get rid of simple things that work well and last years with complicated messes that are awkward and time consuming to install? I could change out the old one in under five minutes. Good thing the new one came with instructions. All down to money is my guess.

Your old one looks like the Schlage A series "Tulip" style knob. I just got a lockset from the site linked above this week.

The A series is commercial grade, grade 2 lock. You can get in different functions, such as entrance lock, classroom lock, store room, and passage....etc. with 'C' keyway.
