A small consulting firm just off West 59th Street and seventh avenue started noticing their office key wasn’t behaving normally. It still worked — but every day it felt a little worse.
When Andrei checked the mortise lock, the early warning signs were clear.
What was happening
The cylinder itself wasn’t completely failed, but:
- internal pins were wearing unevenly
- old lubricant had thickened
- the latch wasn’t retracting fully
Service performed
Rather than replacing hardware prematurely, Andrei carried out a precision lock service:
- cylinder cleaned internally
- proper dry lubricant applied
- latch travel adjusted
- full function test
Result
The key action returned to normal smooth operation.
If your office lock in Midtown Manhattan is getting harder to turn, early service can often prevent full replacement.
