Lock Replacement

Professional Lock Change
Service in Charlotte

Changing a lock means removing the existing hardware entirely and fitting a new lock in its place. It is a different process from rekeying, which changes the internal pin configuration of the same cylinder so the old key no longer works. A full lock change is the right call when the existing hardware is damaged, worn out, or being upgraded to a higher grade, and it is also the only option when the lock itself has been compromised or is no longer functioning correctly.

Charlotte Locksmith's technicians carry a working stock of residential and commercial lock hardware on every vehicle, covering standard deadbolts, knob locks, lever handle locks, and smart lock options in common finishes and grades. Most lock changes are completed in a single visit without requiring a separate parts order, and our technicians confirm the correct hardware for your door and frame before starting work.

We provide lock change service for homes, apartments, offices, retail properties, rental units, and multi-tenant buildings throughout Charlotte and the surrounding communities. Every job includes a written price before work begins and a test of the new hardware before the technician leaves the property.

Lock Types We Replace

Lock Change Services
We Provide

From standard residential deadbolts to commercial-grade mortise locks and smart lock systems, our technicians carry the hardware and tools to replace most common lock types in a single visit.

01

Deadbolt Replacement

Deadbolts are the primary security layer on most exterior residential and commercial doors. We replace worn, damaged, or inadequate deadbolts with new hardware in grade 1, grade 2, and high-security options. If the existing door prep does not match the new hardware, our technicians can adjust the installation to ensure a clean, secure fit without door damage.

02

Knob Lock Replacement

Knob locks are commonly paired with deadbolts on residential entry doors and used on interior doors where a latch with a privacy function is needed. We replace knob lock hardware in standard and keyed configurations, matching the finish and function of the existing installation or upgrading to a different handle style where preferred.

03

Lever Handle Lock Replacement

Lever handle locks are standard in commercial offices and multi-tenant buildings, and are the required hardware type in spaces subject to ADA accessibility requirements. We replace lever handle locksets in commercial-grade cylindrical and mortise configurations, covering most standard door preparations used in office and retail settings throughout Charlotte.

04

Smart Lock Installation

Smart locks replace traditional keyed hardware with keypad, app, or card-based entry and are a practical upgrade for homeowners, short-term rental hosts, and businesses that need flexible access management. We supply and install smart lock hardware for most standard door preparations and configure the initial access codes or app pairing on-site. See our broader residential locksmith page for full details on home security options.

05

High-Security Lock Upgrade

Standard residential deadbolts offer a baseline level of protection but can be vulnerable to picking, bumping, and drilling attacks. High-security lock cylinders use patented keyways, anti-pick pins, and hardened steel construction to resist these methods. We supply and install high-security lock hardware from proven manufacturers and provide the restricted key blanks that prevent unauthorized copying at hardware stores.

06

Mortise Lock Replacement

Mortise locks are installed inside a pocket cut into the door edge and are standard hardware in older residential buildings, commercial properties, and heavy-duty entry doors. They provide a more robust installation than surface-mounted cylindrical locks and are the preferred hardware type for higher-traffic commercial doors. Our technicians replace mortise lock bodies, cylinders, and trim in common configurations without requiring door replacement.

When to change locks Charlotte NC
When to Replace

Situations That Call for
a Lock Change

Rekeying changes the key without replacing the hardware. A lock change replaces the hardware entirely. Both are useful tools, but the right choice depends on the situation. A lock change is the more appropriate option when the existing hardware is damaged, has reached the end of its useful life, needs to be upgraded, or when the physical condition of the cylinder can no longer be trusted.

Moving into a property is one of the most common reasons for a full lock change. The previous owners or tenants may have had copies made over years of occupancy, and there is no practical way to account for all of them. A new lock gives you a clean starting point. The same logic applies to rental properties after tenant changeovers, particularly where the relationship ended on poor terms.

A lock that has been attacked during a break-in attempt should always be replaced rather than just rekeyed, because the cylinder and housing may have internal damage that affects security integrity even if it still operates. Similarly, a lock that has become difficult to operate, is sticking, or is showing visible wear or corrosion is a candidate for replacement rather than a repair that only extends the life of a failing component.

  • Moving into a new home, apartment, or commercial property
  • Lost or unaccounted-for key copies in circulation
  • Lock damaged during a break-in or forced entry attempt
  • Worn, sticking, or corroded hardware that no longer operates smoothly
  • Upgrading from a standard deadbolt to a high-security or smart lock
  • Tenant or employee changeover at a rental or commercial property
Lock Change vs. Rekey

Which Service Do
You Actually Need?

The most common question when calling a locksmith about access control is whether to rekey the existing locks or replace them. The answer depends on the condition of the hardware and what you are trying to achieve.

If the existing locks are in good condition and the goal is simply to make old keys stop working, rekeying is the faster and lower-cost option. The internal pins of the lock cylinder are changed to match a new key, and the old copies no longer operate the lock. The hardware itself stays in place. This is a good option after moving into a property with locks that are still in sound condition, or when a single key has been lost and you want to make it inoperable without changing the hardware.

A lock change is the better choice when the hardware itself is the issue. Damaged cylinders, worn mechanisms, locks that have been attacked, hardware being upgraded for security reasons, or doors where you want a different type of lock all call for a full replacement. Our technicians can assess the current hardware on arrival and give you a clear recommendation on which service makes more sense for your specific situation before any work starts.

  • Rekey: hardware in good condition, goal is new keys only
  • Lock change: hardware damaged, worn, or being upgraded
  • Lock change: after a break-in where the cylinder may be compromised
  • Either: after moving, depending on the age and grade of the existing hardware
  • Our technicians assess on-site and recommend before quoting

Commercial Lock Service

Lock Changes for
Businesses in Charlotte

Commercial properties have different requirements from residential ones. Higher-traffic doors need hardware rated for commercial use, multi-tenant buildings may need master key systems that allow controlled access at different levels, and businesses that have had a staff change need lock changes handled quickly to maintain security without disrupting operations.

Our commercial locksmith technicians work on standard commercial cylindrical locks, mortise locks, and exit device hardware. We can rekey multiple locks to a single key or set up a master key arrangement where different staff members have access to different areas. For offices, retail locations, warehouses, and multi-tenant buildings throughout Charlotte, we carry the hardware to handle most commercial lock change jobs on the same visit.

How It Works

Our Lock Change
Process

Every lock change follows the same process so you know exactly what to expect from the first call through to completed installation.

1

Call With Property Details

Tell us the property type, number of doors, and lock types involved. This helps us confirm we have the right hardware on the vehicle and arrive prepared to complete the job in one visit.

2

Technician Arrives On-Site

A licensed technician comes to your location with a stock of residential and commercial lock hardware in common grades and finishes. They assess the existing hardware and door preparation before recommending options.

3

Written Price Before Work

You receive a written price for the hardware and installation before any work begins. If multiple doors are involved, the technician quotes each door so you can choose which to proceed with. No work starts without your agreement.

4

Installed & Tested

The new lock is installed, aligned, and tested for smooth operation before the technician leaves. You receive the new keys and confirm all functions are working correctly on-site before the job is closed.

Common Questions

Lock Change
FAQs

Answers to the questions Charlotte homeowners and businesses ask most about lock replacement service.

How long does a lock change take?

A single residential lock change typically takes between 20 and 45 minutes depending on the door preparation and the type of hardware being installed. Swapping a standard deadbolt for a direct replacement is at the faster end of that range. Installing a smart lock or a mortise lock, or dealing with a non-standard door preparation, takes more time. If you have multiple doors, each additional lock adds time, and the technician can give you a more accurate estimate once they have assessed the doors on-site.

Can you match the new locks so they all use the same key?

Yes. If you are having multiple locks replaced, we can key all of the new hardware to a single key so one key operates every door on the property. This is called keying alike. It is something to specify when you call so we can confirm the hardware selection allows for it and bring the correct pinning kit. For properties where you want different doors to operate independently, each lock gets its own key instead.

Do I need to replace my locks or just rekey them?

If the existing hardware is in good working condition and you simply need to make old keys stop working, rekeying is typically faster and less expensive than a full replacement. If the hardware is damaged, worn, being upgraded, or was involved in a break-in attempt, replacement is the better choice. Our technicians assess the condition of your existing locks on arrival and give you a clear recommendation before quoting either option. Our dedicated rekey service page explains the rekeying process in more detail if you want to compare.

What brands of locks do you carry?

We stock residential and commercial hardware from established manufacturers in common grades and finishes. For standard residential deadbolts and knob locks, we carry grade 1 and grade 2 options in the most common finishes. For commercial hardware, we carry cylindrical and mortise options suited for office and retail applications. For high-security upgrades, we work with restricted-key systems that prevent unauthorized copying. When you call, let us know if you have a specific brand or grade preference and we will confirm availability.

Can you change locks on an apartment if I am not the owner?

For apartment units, we require the occupant to demonstrate they have authorization to change the locks. This typically means showing a current lease in your name. Some lease agreements require landlord approval before changing locks, and tenants should confirm what their lease requires before scheduling service. For landlords needing locks changed between tenancies, we can schedule the work with the property owner or their authorized representative present.

Do you install smart locks, and what brands do you support?

Yes. We install smart lock hardware for most standard residential door preparations. We work with several keypad and app-based smart lock options and configure the initial access setup on-site. If you already own a specific smart lock you would like installed, we can handle the installation as long as it is compatible with your door preparation. Call with the brand and model and we will confirm whether our technicians carry the correct tools and hardware for that specific unit.
