Broken Key Extraction and Rekey — What Actually Happens on a Service Call
When a key snaps inside a lock, the fragment almost always sits partly in the keyway and partly protruding, or it breaks flush with the plug face. Our technicians first assess the fragment's depth and angle using a penlight and inspection probe before choosing an extraction method. Depending on how the key broke, the technician may use a spiral extractor to hook the serrations, a slim jig extractor to grip the bow stub, or a specialized hook tool designed for narrow keyways found in high-security cylinders. The goal throughout is damage-free extraction — preserving the cylinder so a rekey rather than a full replacement remains an option. For mortise lock cylinders, which are common in older Glen Burnie commercial buildings and Victorian-era rental properties near downtown, the extraction approach differs from a standard pin-tumbler knob lock because the plug must clear a cam at the rear of the housing. Our technicians understand that mechanical difference and work accordingly.
Once the fragment is out, we assess the cylinder's internal condition. If pins or springs have been displaced — which sometimes happens when a key breaks under heavy torque — a simple rekey addresses the problem completely. Rekeying means replacing the driver and key pins inside the cylinder so that a newly cut key operates the lock while every previous key, including any copies that left your possession during a lease change or after a lost-key incident, no longer works. For property managers overseeing multi-unit buildings along Ordinance Road or Dorsey Road, a rekey after a tenant turnover is not optional — it is the responsible standard.
