How Lock Rekeying Actually Works (And Why It's Not the Same as Replacing Locks)
Inside every pin-tumbler lock — the most common type found on Poughkeepsie homes and businesses — is a series of spring-loaded pins of different heights. Your key works because its unique cut profile lifts each pin to exactly the right height, allowing the cylinder to rotate. During a rekeying service, our technician removes the cylinder, replaces those internal pins with a new set of different heights, and cuts fresh keys to match the new configuration. The old key now hits the wrong heights and simply won't turn. The lock body, strike plate, and door hardware stay exactly where they are.
This distinction matters practically. Rekeying is ideal when your existing deadbolts and knob locks are in good mechanical condition — no worn springs, no sticky cylinders, no visible damage from a prior break-in attempt. If your hardware is aged, damaged, or you want to upgrade to a higher-security profile like Schlage B-series or a Kwikset SmartKey cylinder, our technicians will walk you through whether a full lock replacement makes more sense. In many cases, though, rekeying accomplishes the security goal at a fraction of the disruption.
