House Rekeying
Moving into a new home near Shandon, Forest Acres, or anywhere across the Columbia area comes with a long checklist — but one item that's easy to overlook is what to do about the locks. The previous owner, their real estate agent, a contractor, or even a neighbor may still have a working copy of your house key. Rekeying your locks is the fastest, most cost-effective way to take full control of who can and cannot walk through your door, without replacing every lockset on the property.

What House Rekeying Actually Does to Your Locks
When a locksmith rekeys a lock, the internal pin stacks inside the cylinder are replaced with new pins that correspond to a brand-new key cut. Your existing lock hardware stays exactly where it is — same finish, same brand, same look — but any previously cut key immediately becomes useless. This is very different from lock replacement, which involves removing and installing entirely new hardware. Rekeying is especially practical when you have multiple locks throughout the home, because a skilled technician can set all of them to operate on a single master key, eliminating the need for a bulky keyring.
This process works across the full range of residential hardware: standard Kwikset and Schlage deadbolts, door knob locks on interior and exterior doors, lever sets, padlocks, and the more intricate mortise lock found on many older Columbia homes — particularly craftsman bungalows and historic properties in neighborhoods like Elmwood Park and Earlewood. A mortise lock is a cartridge-style lock set into a pocket cut directly into the door edge, and rekeying one requires a technician who understands how its cylinder, cam, and case work together. Our team handles mortise lock rekeying routinely, treating each job with the precision that older or decorative hardware demands.
When House Rekeying Makes the Most Sense for Columbia Homeowners
The most common triggers for a rekey call are straightforward: you purchased or rented a home and want a clean key slate, you ended a relationship or had a roommate move out, you lost a key or had one stolen, or you simply want all your locks to work from one key after years of accumulating different keyways. Each of these situations creates a security gap that a rekey closes immediately. Unlike a full lock replacement, rekeying addresses the actual vulnerability — unknown key copies — without the added cost of new hardware when your existing locks are still in good mechanical condition.
Columbia renters and landlords benefit especially from rekeying between tenants. Property managers handling rentals near the University of South Carolina or in the Vista district know that tenant turnover can leave key accountability unclear. A quick rekey after each move-out restores confidence before handing keys to the next occupant. If you are unsure whether your locks are in good enough shape to rekey or whether replacement would serve you better, our technicians will give you an honest assessment on the spot — no upselling, just a clear explanation of your options before any work begins.

Emergency Locksmith and 24-Hour Availability: What to Expect When You Call
Security concerns rarely wait for business hours. A lost key noticed at 11 p.m., a break-in attempt that compromises your lock, or a late-night move into a new apartment near Bull Street — these are real situations that require an emergency locksmith who is actually available when you call. Mike Columbia Locksmith operates around the clock precisely because these moments do not follow a schedule. When you call (803) 408-4834, you reach a real person who can dispatch a trained technician to your address, not a call center that will leave you a callback window of several hours.
Our 24-hour availability covers more than just rekeying. If you are locked out of your home and need immediate access before we rekey the locks, we handle that too — verifying your identity and ownership before proceeding, consistent with responsible and ethical locksmith practice. We will check whether a window or secondary entrance is accessible to minimize any forced entry, always prioritizing a damage-free approach. Once you are safely inside, we can complete the rekey in the same visit so you go to bed knowing your home is secured with a key only you control. This combination of emergency locksmith response and preventive rekeying in a single trip is one of the clearest reasons Columbia homeowners keep our number saved in their phones.

Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
What does a locksmith do during a house rekeying appointment?+
During a house rekeying visit, the technician removes the cylinder from each lock, disassembles it, swaps out the existing pin stacks for new pins cut to match a newly generated key, reassembles the cylinder, and reinstalls it. Every lock on your home can be set to the same new key in a single visit. The technician will test each lock before leaving to make sure everything operates smoothly. The entire process is non-destructive — your existing hardware stays in place.
Is there a 24-hour locksmith in Columbia, SC?+
Yes. Mike Columbia Locksmith operates 24 hours a day, 7 days a week, including weekends and holidays. Whether you need an emergency locksmith at 2 a.m. after losing your keys or want to schedule a morning rekey the day after closing on your new home, you can reach us at (803) 408-4834 any time. A real team member answers every call.
How much is the average locksmith charge for rekeying a home?+
We do not quote a flat average because the final price depends on several variables: the number of locks being rekeyed, the type of hardware involved (a standard deadbolt, a door knob lock, and a mortise lock each have different requirements), whether any specialized parts or cylinders are needed, the time of day the work is performed, and the travel distance to your location. What we commit to is providing an exact, up-front price before any work begins so you can make an informed decision with no surprises.
Can you recommend a locksmith in Columbia, SC for both homes and businesses?+
Mike Columbia Locksmith serves residential and commercial clients throughout Columbia and the surrounding metro area, including Lexington, Irmo, Cayce, and West Columbia. Our trained, insured technicians handle everything from a single home rekey to full commercial locksmith door hardware projects for offices, retail spaces, and rental properties. Call (803) 408-4834 to describe your situation and we will tell you exactly what we can do for you.
What is the meaning of locksmith, and do I really need one just to rekey a lock?+
A locksmith is a trained professional who works with lock mechanisms, key systems, and door security hardware. While rekey kits exist for some consumer lock brands, rekeying without experience often leads to improper pin seating, a cylinder that sticks or fails, or a lock that appears to work but provides reduced security. A qualified locksmith brings precision tools, the correct replacement pins for your specific cylinder, and the hands-on experience to do the job right the first time — especially important for mortise lock cylinders, high-security keyways, and any hardware that requires matching across multiple doors.
Is there a mobile locksmith in Lexington, SC, or do you only serve Columbia?+
Our service area extends well beyond Columbia proper. We regularly respond to calls in Lexington, Irmo, Cayce, West Columbia, Forest Acres, and other communities in the greater Columbia metro. Being a fully mobile operation means our technicians travel to you — there is no shop you need to visit. If you are in or around Lexington and need a rekey, a lock replacement, or an emergency locksmith response, call (803) 408-4834 and we will confirm arrival time based on current technician location and your address.
