Lock Repair in Jersey City, NJ

What wears on a Jersey City lock

NOAA's climate summary for New Jersey describes moderately cold, occasionally snowy winters, warm and humid summers, and at least one coastal storm a year, with five to ten in some years. Each season works on a stoop door in its own way.

• Winter. Snowmelt can run into an outdoor cylinder and refreeze overnight, so the key goes in but will not turn. Never force the key; let the cylinder thaw or have the lock looked at.
• Summer. Humid air swells wood doors, and the deadbolt starts dragging on the strike. If you have to push, pull or lift the door to lock it, the fix is usually an adjusted strike, not a new lock.
• Storms. Wind-driven rain soaks doors and hardware. If a storm leaves water or grit in a lock, dry it and relubricate it before corrosion sets in.

Repairing older hardware in the row house districts

Most downtown row houses date to the 19th century, so their doors may still carry mortise locks. A weak spring, a sagging latch or a loose cylinder inside a mortise case can often be repaired in place, which keeps the original hardware on the door. In the four downtown historic districts, repairing a historic door, even swapping a worn part for one that matches the original, is done under a Certificate of No Effect from the Historic Preservation Commission. This is general information, not legal advice.

Upkeep between repairs

1. Use a dry lock lubricant in cylinders rather than oil.
2. Tighten loose strike and trim screws before they strip the wood.
3. Try every outside lock after the first hard freeze and again in the first humid weeks of summer.
4. Stop using a lock that sticks until it has been looked at. A key snapped in the cylinder turns a repair into a broken key extraction.

Details for a repair request

Describe what the lock does wrong (sticks, spins, will not latch or will not lock), which door it is (stoop front door, unit door, rear or basement door) and when it started. A photo of the lock and the strike helps. The Jersey City page has the neighborhood picture, and lock repair covers the service itself.
