The buildings and the hardware
The buildings here mean older doors and a mix of houses and multifamily units, so locks are often original or several generations old. Exterior doors may have mortise locks or heavy cast hardware that requires different pins and longer bolts than modern cylindrical latches. Apartment entries and second-floor units sometimes use smaller cylinders or surface-mounted mail slots that complicate access without the right key blank. Storefronts and small commercial spaces tend to have commercial-grade deadbolts and rim cylinders; they wear differently and need heavier-duty parts. That variety is why we bring a wide selection of cylinders, strike plates, and trim pieces on the van.
