Lock Repair in Detroit, MI

How Michigan's seasons wear on Detroit locks

NOAA describes Michigan as having warm, humid summers and cold winters, with the Great Lakes making the state more moist than other north-central states. A wood door takes up moisture through a humid summer and dries out once the heat comes on, so the line between latch and strike moves through the year. A deadbolt that throws easily in January can drag in July, and the fix is often adjusting the strike rather than a new lock.

Winter adds refreezing. Snow that melts against a door in the afternoon can turn to ice inside the latch or cylinder overnight. Use lock de-icer and give it time instead of leaning on the key, since forcing a frozen cylinder can turn a repair job into a broken-key job.

Keeping older hardware in service

The High Victorian houses of Brush Park, near Brush and John R streets, were built for the city's wealthiest citizens. On a house that old, the lock may be original or an early replacement, and repairing it keeps the case and trim on the door. Typical repairs include a broken spring, a loose spindle, a worn cylinder or a shifted strike.

Simple upkeep helps any lock last:

• lubricate the cylinder with graphite or a lock lubricant, not household oil, which collects grit
• tighten loose hinge screws, since a sagging door drags the bolt

Rental doors and the city's checklist

Detroit's Residential Rental 15-Point Inspection Checklist, published by BSEED, includes these items: all entry doors into individual dwelling units have a working lock, one that locks and unlocks without malfunctioning or excessive force, and all windows designed to open are in working condition and have locks. A lock that turns only with a shoulder against the door is worth raising with the landlord in writing. This is general information, not legal advice.

Describing the problem

• what the lock is doing, when it started and whether it changes with the weather
• photos of both sides of the lock and of the door edge
• the street address or block
• for a rental, whether the landlord has approved the repair
