Why a Residential Lock Rekey After Move-In Is the Smartest First Step
When you move into a previously owned or even a newly constructed Alpharetta home, the lock cylinders are already cut to a key you did not personally control. Builders routinely use master-keyed construction cylinders that dozens of tradespeople may have used during the build phase. A lock rekey changes the internal pin configuration of your existing lock so that only the new keys cut for you will operate it — every prior key becomes instantly useless. This is not the same as replacing the entire lockset. Rekeying preserves the hardware you may have just paid for or inherited in a home inspection and is typically a much faster process than a full hardware swap.
The security concern is real and not hypothetical. Alpharetta's rapid growth along the GA-400 corridor has brought a high volume of home sales, short-term rental conversions, and new construction — all situations where key custody is difficult to verify. Rather than trying to track down every copy of an old key, a door lock rekey by a trained technician eliminates the problem entirely. Once the cylinder is rekeyed, the past is locked out — literally.
