Why Broken Key Extraction Requires a Professional Tool Set
Keys break inside locks for a predictable set of reasons: metal fatigue from years of use, a lock cylinder that has stiffened due to lack of lubrication or weather damage, forcing a key that was already bent or cracked, or inserting the wrong key and turning hard. In every one of these scenarios the broken fragment is wedged under spring tension inside the keyway, which means it does not simply fall out when you tip the lock. Mortise lock cylinders — common in older Chatham-area homes and in commercial storefronts along Southern Boulevard — have a narrower, more complex keyway profile than a standard pin-tumbler knob lock, making DIY extraction attempts especially risky. Our technicians understand the geometry of each lock type and select the right extractor the first time rather than improvising with household tools.
The same principle applies to vehicle ignitions. A snapped key in an ignition differs from a door-lock situation because the wafer or disc tumblers inside the ignition cylinder grip the key blade tightly while it is in the run position. Waggling a fragment out without the proper hooked extractor can score the ignition housing or, in newer push-to-start vehicles, damage the transponder reader. We work on domestic and import vehicles alike — sedans, SUVs, trucks, and vans — and our mobile unit is stocked with the ignition-specific tools that dealership service departments use, without the scheduling delay or the tow charge.
