Home Rekeying & Lock Change

Rekeying and replacing a lock are two distinct services that solve the same core problem — unauthorized key access — but in very different ways. When a lock is rekeyed, a skilled technician reconfigures the internal pin tumblers so that only a newly cut key will operate the cylinder. The hardware itself stays in place, which makes rekeying the faster option when your existing deadbolts and door knob locks are in good mechanical condition. A full lock change, on the other hand, removes the existing hardware entirely and installs a new lock set — the right move when the mechanism is worn, damaged, outdated, or simply not up to the security standard you want. Our technicians are experienced with a wide range of residential hardware, including Schlage and Kwikset deadbolts, mortise lock assemblies, smart locks, and multipoint door systems. A mortise lock, common in older Smyrna bungalows and renovated craftsman homes, requires a technician with specific hands-on experience because its internal cartridge fits into a routed pocket inside the door itself — not all locksmiths carry the right replacement cartridges or know the correct procedure. Our team does.

Here is a quick guide to which service fits your situation: choose rekeying if you have moved into a property, ended a relationship with someone who had a key, lost a key with no sign of theft, or want to put all your exterior doors on one master key. Choose a lock change if the hardware is damaged, if you are upgrading security after a break-in attempt, if you want a specific new lock brand or grade, or if the existing lock style is incompatible with a new door or frame. Not sure which applies to you? Call (770) 816-8255 — we answer 24/7 and can help you decide over the phone before we even dispatch a technician.

For properties running Defiant or Honeywell smart lock hardware, our technicians can walk you through a defiant lock change code reset or a honeywell door lock change code procedure as part of the service visit, ensuring the new code sequence is fresh and known only to you. If your existing hardware uses a master lock change combination dial, we can service that as well. We do not limit ourselves to one brand ecosystem — if it locks a door in Smyrna, we work on it.
