Earlier this week, technician Andrei was dispatched to a commercial office on West 56th Street in Midtown Manhattan for a lock repair issue affecting a private suite door.
The problem
The office manager reported:
- Key turning with heavy resistance
- Cylinder occasionally sticking
- Door sometimes not latching fully
This is a classic early-stage mortise cylinder failure.
Diagnosis
Upon inspection, Andrei found:
- Worn pins inside the cylinder
- Minor misalignment between latch and strike
- Heavy lubricant buildup from previous DIY attempts
The repair
Instead of replacing the entire lock, Andrei performed a precision lock repair that included:
- Full cylinder rebuild
- Proper dry lubrication
- Strike plate adjustment
- Door alignment check
Final result
The key now turns smoothly and the office door secures properly.
