Why Broken Key Extraction Demands a Professional Touch
When a key snaps inside a mortise lock — the kind of deep-set, multi-component lock common in older residential and commercial buildings throughout Tenafly — the broken segment is often seated well inside the cylinder, past the shear line, where amateur removal attempts with tweezers or bobby pins do far more harm than good. Mortise lock cylinders are precision components; gouging the interior or jamming the fragment sideways can destroy the cylinder entirely, turning a straightforward extraction into a full cylinder replacement. Our technicians carry purpose-built extractors — hook picks, spiral picks, and broken-key extractors sized to specific cylinder profiles — that allow us to draw the fragment out along the original key path without enlarging or distorting the keyway.
The same principle applies to door knob lock cylinders on interior and exterior residential doors, commercial deadbolts, and even padlocks securing storage units or gates. Every lock type has a different keyway geometry, pin stack configuration, and cylinder length, which means the extraction method that works cleanly on one lock can crack the housing on another. That is why our technicians assess the lock first, confirm the approach, and give you a transparent, up-front price before any tool touches your lock. If you are dealing with a stuck fragment right now, call 201-425-6211 — we answer 24/7 and can typically reach most Tenafly addresses within a short window.
