Lock Repair in Portland, OR

What wet winters do to Portland doors

NOAA's 2022 state summary describes Oregon as split by the Cascades, with a wet west side and a much drier east. Portland's Willamette Valley setting puts its doors on the wet side, and winter is the wet season across most of the state. Months of damp show up at the door in familiar ways:

• Wood doors and frames take on moisture and swell, so a latch or deadbolt drags on the strike plate or will not throw all the way.
• When the weather dries out, the door can shrink back and the latch may stop catching.
• Steel parts in exterior locks and strikes can rust, and the key starts to feel gritty.

A deadbolt that locks only when you lift or push the door is usually misaligned, not broken. Adjusting the strike plate or tightening the hinge screws often cures it. Forcing the key can bend it or snap it in the cylinder.

Older hardware and simple upkeep

Some Portland houses predate 1940 and may still have the original mortise lock, with the latch, bolt and springs in one box inside the door edge. When one wears, a broken spring, a worn spindle or a tired cylinder can often be repaired without replacing the whole lock, which keeps an old door and its trim intact.

Upkeep that helps any lock on the wet side of the state:

• Check exterior locks at the end of winter, after the wettest months.
• When a key starts to drag, use a dry lock lubricant, not oil.
• Tighten loose screws on knobs, strikes and hinges before they strip.
• Watch that new weatherstripping does not push the door away from the latch.

Under Portland City Code 29.30.100.D, the owner of residential property must keep each exterior door, hinge, lock and strike plate in good condition, with the door fitting reasonably well in its frame. A swollen door that will not latch is that kind of problem. This is general information, not legal advice.

What to describe

For lock repair, say what the lock does wrong, whether it changes with the weather, and what type of lock it is, with a photo of the edge where the latch sits. If a key has already snapped, see broken key extraction.
