Should You Rekey Your Locks After Moving to a Nashville Home?

When a locksmith rekeys a door lock, they disassemble the lock cylinder and replace the tiny internal pins — called key pins and driver pins — with a new set sized to match a completely different key cut. The result is that every old key becomes useless, and only the new key you walk away with will operate the lock. The hardware itself stays exactly where it is: the deadbolt, the strike plate, the mortise lock body if you have one, all remain in place. This is fundamentally different from replacing a lock, where the entire mechanism is removed and a new unit is installed. Because rekeying is less labor-intensive and requires only a small set of replacement pins rather than a full new lockset, the process is typically quicker and involves fewer parts.

How do you rekey a lock, practically speaking? A trained locksmith uses a plug-following tool to remove the cylinder plug, identifies the existing key bitting, selects new pins from a pinning kit to match a new key cut, reassembles the plug, and tests the new key several times before calling the job done. It sounds simple in theory, but doing it correctly — especially on higher-security cylinders, antique mortise lock hardware, or multi-point locking systems common on newer Nashville construction — requires experience and proper tools. A single misplaced pin can leave you with a lock that binds or fails entirely, which is why this is a job best left to a professional rather than a weekend DIY attempt.

Rekeying beats replacement in most situations a new homeowner faces. If the locks are in good working condition — no sticking, no visible wear on the cylinder, the deadbolt throws cleanly — there is no mechanical reason to swap them out. The only problem is the unknown history of the keys, and rekeying solves that completely. Nashville's older housing stock, particularly the mid-century ranches in Antioch or the Victorian-era homes near Germantown, often features solid mortise lock hardware that would be expensive and disruptive to replace but can be rekeyed without touching the door frame or the decorative escutcheon plate. Rekeying is also the right call when you want can you rekey a lock to match existing key scenarios — for example, if you want all three exterior doors in your home to open with a single key, a locksmith can rekey each cylinder to the same cut, a process called keying alike.

You should lean toward full lock replacement when the cylinder shows signs of wear or damage, when you want to upgrade to a higher-security rating like ANSI Grade 1, or when you're switching from a standard keyed knob to a smart lock or a heavy-duty deadbolt. Renters face a specific wrinkle: Tennessee landlord-tenant law does not automatically grant tenants the right to rekey or replace locks without landlord approval, so check your lease and get written permission before calling us out. If you're a landlord managing a property anywhere across Nashville's 42-plus ZIP codes — from 37201 downtown to 37221 out in Bellevue — rekeying between tenants is a simple, professional practice that protects both your asset and your new occupant.

Smart locks add a layer of complexity to the rekeying conversation. Can you rekey a smart lock? It depends entirely on the make and model. Some smart locks — including certain Schlage and Kwikset smart lock lines — are built around a traditional keyed cylinder that sits alongside the electronic components, meaning that cylinder can be rekeyed just like a standard deadbolt. Others are fully electronic with no physical key cylinder at all; for those, 'rekeying' means resetting the access codes and deleting old user credentials, which is something you should do immediately after moving in regardless. Can you rekey a Yale smart lock? Many Yale models use a proprietary cylinder, so the answer depends on the specific product and whether compatible pins are available — our team can assess your unit on-site and give you a straight answer before any work begins.

Mortise lock hardware deserves special attention here. A mortise lock is a full-body lock mechanism that sits inside a pocket (the mortise) cut into the door edge, common in pre-1970s Nashville homes and high-end commercial doors. These locks are more complex internally than a standard cylindrical lockset, but a skilled locksmith who works regularly with mortise lock cylinders can rekey them efficiently. If you have a beautiful original mortise lock on a historic home near Music Row or 12 South, rekeying is almost always preferable to replacing it — reproduction mortise hardware is expensive, and original hardware often has a fit and finish that modern replacements cannot match. Our team at A1 Nashville Locksmith handles mortise lock rekeying as a core part of our residential and commercial locksmith work across the Nashville area.

We never publish flat-rate price tables for one honest reason: two rekeying jobs that look identical on the surface can involve very different amounts of time, parts, and travel. The factors that shape your final quote include the type and brand of lock (a standard Kwikset deadbolt and a high-security mortise lock cylinder require different pin kits and different levels of expertise), the number of locks being rekeyed in a single visit, the time of day (an emergency locksmith call at 2 a.m. on a Saturday involves different logistics than a scheduled afternoon appointment), and travel distance within the Nashville metro. If you're in Madison or Hermitage versus closer to downtown, that distance is factored in. What we commit to every time: we confirm an exact, up-front price before a single tool comes out of the bag. You know what you're paying before work begins — no surprises on the invoice.

What is the average call out fee for a locksmith? That varies by provider, location, and time of day, and any honest answer has to account for those variables. What we can tell you is that at A1 Nashville Locksmith, the call-out component is always included in the up-front quote we give you — it is never added as a hidden line item after the job. If you are weighing rekeying against full replacement, ask us to quote both during the same call. In many cases, rekeying several locks costs meaningfully less than replacing even one quality lockset, which makes the decision straightforward for most Nashville homeowners. Ready to get your quote?

Yes — a professional locksmith can open a locked door through non-destructive methods in most standard lockout scenarios, and will always verify your right to access the property first.
