The buildings and the hardware
The housing stock in Hatfield Township affects the hardware you find. Older detached houses often keep mortise locks and bolted wooden doors that require different parts and techniques than modern bored cylindrical locks; you’ll see brass or bronze trim and deeper bolt cases. Newer subdivisions and many rentals use cylindrical deadbolts and metal-sheathed doors that accept standard replacement cylinders and latch assemblies. Apartment and multifamily properties usually have master-key systems or keyed-alike sets, which changes how we approach rekeying and spare-key work to keep common entries secure without cutting separate keys for every unit.
