What Home Rekeying Actually Does to Your Locks
Rekeying does not replace the lock hardware on your door — it replaces the tiny pins inside the lock cylinder so the old key no longer works and a fresh key is cut to match the new pin configuration. This applies to the most common residential hardware people encounter: standard door knob locks, deadbolts, lever-handle locks, and the more complex mortise lock assemblies found on older or upgraded Oliver Springs homes. A mortise lock is a full-body lock unit that sits inside a pocket cut into the door edge, combining a latch, deadbolt, and often a privacy function into a single robust cartridge. Because mortise locks contain multiple working components, rekeying them correctly requires a trained technician rather than a quick DIY attempt — our team carries the specific tools and replacement pin kits for mortise lock cylinders of multiple makes and sizes.
Beyond the standard cylinder-based hardware, we also work on several lock types that homeowners in this area encounter but rarely hear discussed by name. Tongue locks — named for the spring-loaded latch tongue that projects from the edge of the door — are among the most common latching mechanisms in residential use and can be rekeyed when paired with a keyed cylinder. Roller pin locks use a rotating pin tumbler system that requires manufacturer-specific tooling to service properly. Round bolt locks feature a cylindrical bolt rather than a tapered latch, typically found on older interior and storm doors across Morgan County homes. Swing hook locks, which are common on folding or bi-fold doors and certain patio applications, secure the door by swinging a hook-shaped bolt into a strike plate; these require careful disassembly before the cylinder can be accessed for rekeying. Our technicians are experienced with all of these mechanisms and will identify exactly which lock type is installed before quoting any work.
