Why a Home Rekeying or Lock Change Matters More Than Most People Realize
When a key goes missing — left at a restaurant on Knox Abbott Drive, dropped in a parking lot, or simply unaccounted for after a move — the physical lock itself is still open to whoever finds it. Rekeying changes the internal pin configuration of your existing lock cylinder so that only the new key works, rendering every previous copy useless overnight. A full lock change goes a step further, replacing the entire hardware unit with a new mechanism, which is the right call when the existing lock is worn, damaged, outdated, or simply not up to the security standard you want. Either service restores exclusive control of your home to you and the people you choose to give access to.
For new homeowners and renters in Cayce, this is especially important. Real estate transactions, rental turnovers, and contractor visits can leave a surprising number of key copies in circulation — previous owners, real estate agents, maintenance crews, and neighbors may all have had access. A single service call from Troy Locksmiths resets all of that. Our mobile technicians arrive with the parts, tools, and experience to rekey or replace locks on standard door knob lock sets, deadbolts, mortise lock assemblies, sliding patio doors, and more — damage-free wherever the hardware allows.

What Determines the Price of a Lock Change or Rekey
Pricing for a door lock change or rekey depends on several variables, and we believe you should understand exactly what goes into your quote before you agree to anything. The primary factors are the type and brand of lock involved (a basic door knob lock set costs less in parts and labor than a heavy-duty commercial mortise lock), the number of locks being serviced in a single visit, the time of day the call comes in (our 24/7 availability means our team is on the road at 2 a.m. if you need them, and after-hours calls carry a different rate than standard daytime appointments), and the travel distance to your specific location in the Cayce area. If replacement parts or new hardware are needed beyond a standard rekey, those components factor into the final figure as well.
What never changes is our process: one of our technicians gives you a confirmed, exact price before any work begins. You decide whether to proceed. There are no surprise line items added after the job is done. If you are unsure whether rekeying or a full lock change is the more cost-effective path for your situation, our technician will walk you through both options and let you make an informed choice. To get a straight answer on your specific door and lock type, call (000) 000-0000 — we answer 24/7 and can often give you a ballpark over the phone before we even arrive.
Mortise Lock Specialists and Emergency Locksmith Response in Cayce
A mortise lock — the kind set into a rectangular pocket cut into the edge of the door rather than mounted on the face — is one of the most secure and durable lock types available, and it is common on older Cayce homes, historic properties near the State Road corridor, and commercial buildings that were built before cylindrical locks became the standard. Rekeying or replacing a mortise lock requires a different skill set than swapping a standard deadbolt, and not every technician carries the right parts or knows the nuances of the mechanism. Troy Locksmiths specifically trains for mortise lock service, so whether your unit is a century-old antique or a modern high-security version, we can rekey it, repair it, or replace it with a compatible upgrade.
Our emergency locksmith response covers more than lockouts. If you have experienced a break-in, a door has been damaged, or you simply realize at midnight that an ex-tenant still has a working key, we treat that as the urgent situation it is. Cayce's relatively compact geography means our mobile technicians can reach most addresses in the area quickly, but we never rush a job — every rekey or lock change is done methodically so the new hardware functions perfectly and your door closes and latches correctly every time.
What to Ask Before You Hire Any Locksmith — and What to Expect From Ours
Before you let anyone work on your locks, a few questions protect you: Can they confirm pricing before starting the job? Do their technicians arrive in a marked, identifiable vehicle? Are they insured? Can they verify their identity and the nature of the work required? At Troy Locksmiths, the answer to all of these is yes. Our technicians carry identification, arrive in marked vehicles, are fully insured, and will never begin work without your explicit approval of the quoted price. We also confirm your ownership or authorized-occupant status for the property before any lock is opened or changed — this is a standard professional practice that protects you as much as it protects us.
We also want residents throughout Cayce to feel comfortable asking questions. If you want to know whether rekeying is sufficient or whether a full hardware replacement is smarter for your specific door, ask. If you want to understand the difference between a mortise lock and a cylindrical lock before choosing new hardware, ask. Our technicians treat every service call as an opportunity to leave you better informed about your own home security, not just to complete a task and leave.
Frequently asked questions
What is the difference between rekeying a lock and doing a full lock change?
Rekeying adjusts the internal pins inside your existing lock cylinder so that your old keys no longer work and a new key is required. The lock hardware stays in place. A full lock change removes the entire lock unit and installs new hardware. Rekeying is often sufficient when the lock is in good condition and you simply want to revoke access from previous keyholders — for example, after moving into a new Cayce home. A lock change makes more sense when the hardware is worn, damaged, outdated, or you want to upgrade to a higher-security option like a commercial-grade mortise lock or a smart lock with keypad access.
What should I ask a locksmith before hiring them?
Ask whether they will confirm the exact price before beginning work — any reputable locksmith will do this. Ask whether their technicians are insured and whether they arrive in an identifiable vehicle. Ask how they verify that you are authorized to have the lock changed on the property. Ask what brands of hardware they carry and whether they have experience with your specific lock type, whether that is a standard deadbolt, a door knob lock set, or a more complex mortise lock. At Troy Locksmiths, we are happy to answer all of these questions before we begin — call (000) 000-0000 anytime.
How much does a door lock change or rekey cost?
The final price depends on several factors: the type of lock being serviced (a mortise lock involves different parts and labor than a basic door knob lock), the number of locks on the property, the time of day the service is requested, travel distance within the Cayce service area, and whether new hardware or parts are needed. We do not quote a single flat figure here because every job is different — but we always provide an exact confirmed price before any work begins, so there are no surprises on the final invoice. Call (000) 000-0000 and we can often narrow down the estimate over the phone based on your lock type and situation.
Is it cheaper to go to a locksmith or handle a lock change myself?
DIY lock replacement is possible on basic cylindrical hardware if you are comfortable with basic tools, but mistakes — misaligned strikes, incorrect bore sizing, or improper installation — can leave a door that does not latch correctly or a lock that fails prematurely. Mortise locks, high-security deadbolts, and commercial lock change projects almost always require professional installation to function correctly and maintain the security they are designed for. A trained locksmith also has the tools to rekey a lock in minutes, which is typically faster and less disruptive than a full DIY hardware replacement. For complex hardware or whole-property rekeying in Cayce, a single professional visit is usually more efficient than multiple hardware store trips and partial attempts.
Can you rekey or change locks on a commercial property, not just a house?
Yes. Troy Locksmiths handles commercial lock change projects including office buildings, retail spaces, rental properties, and multi-unit residential buildings throughout the Cayce area. Commercial work often involves higher-grade hardware — heavy-duty mortise locks, exit devices, panic bars, and access control systems — and we carry parts and experience for all of it. If you manage a business and need to restrict access after a staff change or a security concern, our commercial locksmith team can rekey or replace every entry point in a single visit and help you set up a master key hierarchy if needed.
What is the violent crime rate in Cayce, South Carolina, and should it change how I think about my locks?
Cayce is a relatively safe mid-sized city in Lexington County, but like any community, it does see property crime and occasional incidents that remind homeowners and business owners not to take door security for granted. The most practical takeaway for any Cayce resident is this: the quality and condition of your locks matter as much as any other security measure. An outdated, worn, or previously compromised lock — especially one that has gone through multiple key generations — is a vulnerability that a rekey or lock change resolves completely. If you have moved recently, lost a key, or experienced any unauthorized entry, an emergency lock change is the fastest way to restore genuine security to your property.
