Lock Replacement in Pittsburgh, PA

Replacing locks on older Pittsburgh doors

Census Bureau estimates for 2024 put nearly 47 percent of Pittsburgh's homes in buildings from 1939 or earlier, about four times the national share of 11.5 percent. A door that old can carry several generations of hardware: an original mortise lock, a deadbolt added decades later, and filled holes from locks long gone. Replacing a lock there often means fitting new hardware to existing bores and a frame that may have moved, not dropping a standard lockset into a standard hole.

Replacement makes sense when a cylinder is worn enough that keys catch, the bolt won't throw fully with the door aligned, parts are broken and unavailable, or you want a sturdier deadbolt on a side or rear door. When the lock is sound but sticky, lock repair may keep it in service.

Front doors in the Mexican War Streets and other districts

The city lists 16 locally designated historic districts. Exterior alterations in them need a Certificate of Appropriateness from the Historic Review Commission under Pittsburgh Code Chapter 1101, and some routine projects can be approved by staff at the counter. The commission's Mexican War Streets guidelines show how doors are treated:

• Only what can be seen from a public street or alley is covered; interiors are not.
• Historic doors and their hardware are favored, and paneled wood doors are called appropriate for houses.
• Steel doors are suggested only for side and rear walls with little visibility, not the main facade.
• A replacement that matches the existing appearance exactly can be approved by staff without a hearing.

Other districts have their own guidelines, so read the one covering your street before choosing new front-door hardware. This is general information, not legal advice.

What to send with a replacement request

• photos of the lock from outside and inside, and of the door edge showing the latch or bolt plate
• the door material: original wood, newer wood, steel or fiberglass
• whether the house is in a historic district and whether the door faces the street
• whether the new lock should take the same key as your other doors
