The buildings and the hardware
Homes and small commercial buildings in this part of Delaware County often put older hardware into play. Many front doors still have heavy, long-lived mortise or rim locks and original door construction that requires careful fitting rather than swapping in a modern cylindrical lock. Apartment buildings tend to use keyed-alike or master-key systems, which changes how we approach rekeys and replacements because you can’t treat each cylinder as independent. Storefronts and small businesses usually have surface-mounted exit hardware or panic bars that need different parts and techniques than a typical residence.
