When Should You Replace Your Door Locks Instead of Rekeying?

Rekeying a lock means a locksmith technician changes the internal pin configuration inside the lock cylinder so that the old key no longer works. The hardware — the lock body, the strike plate, the door knob lock or deadbolt housing — stays exactly where it is. This is a fast, effective solution when the lock itself is in good mechanical shape but you no longer trust who holds a key to it. Common scenarios include moving into a previously owned home, ending a relationship with a roommate or contractor, or after a key is lost or stolen. If you have ever wondered how to change your door lock without buying new hardware, rekeying is essentially the answer.

Replacing a lock means removing the existing lockset entirely and installing new hardware. This is necessary when the lock mechanism is damaged, when you are upgrading your security level, when a lock no longer fits the door properly, or when you are switching lock types altogether — for example, asking whether you can replace a mortise lock with a cylindrical lock involves a full replacement and sometimes door prep work. The right choice between these two paths comes down to four practical factors: the condition of the hardware, the lock type, the security threat involved, and how the lock fits your door.

There are clear situations where rekeying simply will not fix the problem. If your lock is visibly damaged — the bolt does not throw smoothly, the cylinder spins loosely, the door knob wobbles or catches — no amount of rekeying will restore function. A lock that was forced during a break-in attempt may look intact from the outside but have internal components that are bent, cracked, or misaligned. Similarly, if your existing locks are decades old and the finish is worn through, the springs are weak, or the keyway is a generic low-security profile, this is the right moment to invest in a modern replacement rather than rekying hardware that is already near the end of its life. For homeowners on Augusta's older streets — including neighborhoods near Summerville or homes built in the mid-century around the Hill — original mortise locks are common. A mortise lock is a rectangular lock body that sits inside a pocket cut into the door edge, rather than sitting on the surface the way a cylindrical lockset does. When a mortise lock's internal mechanism wears out, replacement parts can be hard to source and a full swap to a new mortise lock or a quality cylindrical deadbolt is often the more practical path.

You should also replace rather than rekey if your lock was defeated or bypassed during a break-in. Even if the door itself held, a lock that has been attacked with a pry bar, hammer, or other tool may have compromised internal parts. Another clear sign: if you have jimmy proof door locks (interlocking deadbolts common on apartment doors and older commercial entries in Augusta) and the interlock mechanism is grinding or failing to engage cleanly, a rekey will not restore the mechanical security you depend on. A trained locksmith can inspect the hardware in minutes and tell you definitively whether the mechanism is still sound.

Rekeying is the right call when the lock itself is in excellent mechanical condition and the only concern is key control — meaning you want to make sure certain people can no longer enter your home. Just moved into a house off Washington Road or taken over a rental property in Augusta? The previous owners, their relatives, their contractors, and anyone they may have given a spare key to could still have access. Rekeying all entry locks to a single new key is fast, thorough, and eliminates that risk without replacing hardware that may have years of good service left.

Rekeying also makes sense when you want all your locks to work on the same key — a process called key consolidation or master keying — and the existing hardware is compatible. If you have three or four door knob locks and deadbolts on your home, each currently needing a different key, a skilled locksmith can rekey them so a single key opens every entry point. That is a meaningful convenience upgrade with no new hardware required. The important caveat: rekeying only works if the lock cylinder itself is a rekeyable type and is in sound working order. A mortise lock cylinder, a Schlage B-series deadbolt, and a Kwikset knob lock are all rekeyable, but the process and tooling differ — which is exactly why this job is best left to an experienced locksmith rather than a DIY attempt.

The type of lock on your door significantly affects whether a rekey or replacement is appropriate — and sometimes the answer is neither, because what you actually need is a different lock type entirely. A mortise lock is the most common example. These locks are standard on many historic Augusta homes, older apartment buildings, and commercial properties throughout the CSRA. When functioning correctly, a quality mortise lock provides excellent security because the large lock body is embedded deep in the door. But because the entire mechanism lives inside the door, a failing mortise lock often requires a full replacement of the lock body, not just a cylinder swap.

Commercial properties have their own set of considerations. A commercial door locksmith works with hardware that residential locksmiths may not stock — including commercial glass door locks, mortise lock cylinders with restricted keyways, panic hardware, and electronic access systems. If you manage a business on Broad Street or own a retail space in the Augusta area and your commercial entry hardware is failing or your key control has been compromised by employee turnover, the question of rekey versus replace carries real liability weight. Commercial mortise lock cylinders can often be rekeyed quickly to restore access control, but if the lock body itself is worn or the wrong security grade for the traffic your door handles, a commercial locksmith will recommend replacement and specify the correct grade of hardware.
