Lock Replacement in Portland, OR

Old doors and new hardware

Replacement fits when the hardware itself has given out: a cracked cylinder, a latch that no longer catches, a deadbolt with a short throw, or a lock you want to upgrade. Portland's housing is older than Salem's, Eugene's or Bend's. Census Bureau estimates for 2024 put 25.9 percent of its homes before 1940.

Ladd's Addition shows what that can mean at the door. William S. Ladd subdivided it in 1891 on a diagonal plan, between SE Hawthorne, Division, 12th and 20th. Most of its houses went up between 1905 and 1930, among them bungalows, Craftsman homes and American Foursquares, with some Tudor, Mission and Colonial Revival designs. A door of that age may still hold a mortise lock set into a pocket cut in its edge. There are two routes:

• Replace the mortise lock body with a new one of the same size, keeping the door, the trim and the look.
• Convert to a bored knob lock and deadbolt, which means filling the old pocket and drilling new holes. On an original door that is hard to undo.

Measure or photograph the lock face, the backset and the door thickness before choosing.

What the city code expects

Portland City Code Chapter 29.30, Housing Maintenance Requirements, applies to residential property and holds the owner to it:

• 29.30.100.C: each exterior door of a dwelling unit needs a lock that opens from the inside without a key or special knowledge or effort. Check that a new lock keeps that inside operation.
• 29.30.100.D: exterior doors, hinges, locks and strike plates must be kept in good condition, and each door must fit reasonably well in its frame.
• 29.30.090.G: a window that opens within 10 feet of the exterior grade must latch securely from the inside and open from the inside without a key.

This is general information, not legal advice.

Photos and details that help

For lock replacement, send photos of both faces of the lock and of the door edge, say whether the door is original to an older house, and say whether you want every door on one key. If the hardware is sound and only the keys are the worry, lock rekeying is the simpler job.
