The buildings and the hardware
The housing stock here often means older doors and a wide mix of hardware types, so you’ll see everything from vintage mortise locks to modern cylindrical deadbolts. Single-family houses tend to have full-size doors with wider stiles that accept heavy-duty deadbolts and multipoint assemblies; small apartment entries and storefronts more often use cylindrical locks and commercial-grade lever handles. Older mortise cases can be brittle or corroded and often require careful extraction or a cylinder swap, while newer doors usually allow a straightforward cylinder or keypad upgrade. That variety affects parts on the van and the time a repair takes.
