What Rekeying Actually Does — and Why the Terminology Matters
Homeowners often use 'rekeying' and 'lock replacement' interchangeably, but they describe entirely different operations. When a locksmith rekeys a lock, the cylinder's internal driver pins and key pins are removed and replaced with a new set sized to match a newly cut key. The lock body, the bolt mechanism, and all the hardware you see on the door remain exactly as they were. Lock replacement, by contrast, means removing the entire lock unit and installing new hardware. Rekeying is the right call when your existing hardware is in solid working condition but the key control has been compromised — after a move, after a lost key, or after handing spares to people you no longer trust.
Understanding a few more terms helps you have a sharper conversation with your technician. 'Key control' refers to your ability to know and manage every copy of a key that opens your lock. 'Pinning' is the hands-on process of selecting and installing the correct pin stack inside the cylinder. A 'mortise lock' is a full lock mechanism — including the latch, deadbolt, and cylinder — that is set into a routed pocket (the mortise) inside the door edge, common in older homes and higher-end construction throughout the Lockhart area. A 'door knob lock' integrates the cylinder directly into the knob, typical of interior and secondary exterior doors. Knowing these distinctions helps you describe your locks accurately so our technicians arrive with exactly the right parts.
