Why Keys Break and Locks Jam — and What That Means for Your Property
Keys fail for surprisingly predictable reasons: metal fatigue from years of daily use, a lock cylinder that has gone too long without lubrication, or the simple bad luck of forcing a slightly bent key under pressure. In Columbia's humid subtropical climate, seasonal expansion and contraction of door frames — particularly common in older craftsman homes in Shandon or the warehouse conversions along Gervais Street — accelerates wear on both the key and the cylinder. The result is a key shank lodged deep in the plug, a broken tip lodged behind a mortise lock faceplate, or a wafer that has corroded enough to bind the cam entirely. Understanding the root cause is not just academic: it determines which extraction method a technician will use, whether the lock can be serviced in place or must be replaced, and ultimately what parts — if any — need to be ordered.
Jammed locks tell a different story. A deadbolt that turns halfway and stops, a rim lock that spins freely without retracting, or a lever handle that depresses but does not release the latch are each symptoms of distinct internal failures. Our technicians are trained to diagnose these differences on sight, which means you are not paying for guesswork — you are paying for a precise, efficient solution delivered at your door.
