Why Keys Snap and When Broken Key Extraction Is the Right Call
Keys break inside locks for a handful of very specific reasons: metal fatigue from years of daily use, a lock cylinder that has stiffened due to lack of lubrication or debris buildup, a sudden twist with too much lateral force, or an already-duplicated key that was cut slightly off-tolerance. Atlanta's climate plays a role too — the city's humidity spikes every summer, causing wooden door frames to swell and put extra torque pressure on locks along historic bungalows in Grant Park or older commercial storefronts near Auburn Avenue. When that stress concentrates at the bow of the key and the metal gives way, the broken portion disappears into the keyway and the lock becomes inoperable.
The instinct to grab tweezers or a straightened paperclip is understandable, but probing the keyway with improvised tools almost always pushes the fragment deeper, compresses the pin stack, or scores the cylinder wall — turning a simple extraction into a full lock replacement. Our technicians carry purpose-built broken key extractors, plug followers, and illumination tools specifically sized for the most common residential and commercial lock profiles found throughout Atlanta. Calling (470) 681-9505 the moment a key snaps — rather than after a DIY attempt — gives us the best chance of a clean, damage-free removal that preserves your existing lock.
