Home Rekey & Lock Change — What's Actually the Difference?
Rekeying means a technician disassembles the existing lock cylinder and replaces the internal pin tumblers so that only a brand-new key will operate it. Your physical hardware stays in place — the deadbolt body, the strike plate, the finish. A full lock change means the entire lockset is removed and replaced with new hardware. Both services eliminate access by anyone holding your old key. The right choice depends on the condition and age of your current locks, whether you want to upgrade the security grade, and whether you need all exterior locks to operate on a single master key — a service called keyed-alike rekeying that is especially popular with Bexar County homeowners managing a rental property or a multi-unit dwelling on the west side of San Antonio.
Rekeying is generally the better fit when your existing hardware is in good working order and you simply want to invalidate old keys after a move, a tenant departure, or a lost key incident. A full door lock change makes more sense when the lock mechanism is worn, when you're upgrading from a builder-grade knob set to a heavy-duty deadbolt, or when a door knob lock has been damaged during a break-in attempt. Our technicians will inspect your doors on arrival and give you an honest recommendation — not the one that costs more, but the one that actually fits the situation.
Mortise Lock Service, Door Knob Lock Replacement & Every Lock Type We Handle
Not all exterior locks are created equal, and Bexar County's housing stock reflects that variety. Older homes in Dignowity Hill or Monte Vista often feature a mortise lock — a large, rectangular lock body that sits inside a pocket routed into the door edge, combining a latch, deadbolt, and sometimes a lever handle into one integrated unit. Mortise locks are robust, but they require a skilled hand to rekey or replace correctly; improper disassembly can crack an antique door stile. Our technicians are experienced with mortise lock service on both wood and metal doors, carrying replacement mortise cylinders from trusted hardware brands like Schlage and Kwikset. We also service standard cylindrical deadbolts, handlesets, knob sets (door knob lock replacement is one of our most common calls after a move), keypad and smart lock installations, sliding door locks, and multi-point locking systems on fiberglass entry doors.
Beyond residential hardware, we regularly handle commercial lock change requests — from a small office suite near the South Texas Medical Center needing a single cylinder swap to a warehouse on Hwy 90 requiring a full commercial locksmith overhaul with grade-1 deadbolts across every access point. If your property uses Defiant hardware and you need a defiant lock change code reset on a keypad model, or a Honeywell door lock change code update after a staff departure, our technicians can walk through the electronic reprogramming as part of the same visit. We stock common residential and commercial grades on the truck, which means most jobs are completed in a single trip.
After a Move or Lost Key — When to Call for a Rekey Locks Service Bexar County
Real estate closings in Bexar County set a record pace in recent years, with neighborhoods like Alamo Ranch, Sonterra, and the East Side seeing steady turnover. Every time a home changes hands, the lock cylinders on every exterior door — front entry, back door, garage entry, and any gate locks — should be rekeyed or replaced before the new owner spends a single night inside. The previous owners, their real estate agent, the cleaning crew, and anyone else who was handed a copy during the listing period may still have a working key. A rekey lock service visit from our team typically takes under an hour for a standard three-to-four-door home, and we can do it the same day you close — even if closing runs late and you're calling us at 9 p.m.
Lost keys create a similar risk window that many homeowners underestimate. A key that falls out of a pocket at a Spurs game at Frost Bank Center or goes missing during a move doesn't announce itself as stolen — but it may be. If the key has no address tag, the risk is lower; if it was on a ring with mail or a loyalty card showing your name, the calculus changes. Either way, a rekey locks near me call is the fastest resolution. Our 24/7 dispatch means a technician can be rolling toward your address whether you call at noon or 3 a.m. Call (210) 512-4768 and we'll confirm an estimated arrival window immediately.
How Pricing Works — No Surprises, No Hidden Fees
We don't publish flat rates on this page because lock change service pricing is genuinely variable — and any number we printed here wouldn't reflect your actual job. The factors that shape your final quote include the type and security grade of lock involved (a basic knob rekey differs from a full mortise lock replacement), the number of doors being serviced, whether parts need to be pulled from truck stock or a specific brand ordered, the time of day the call comes in, and your location within Bexar County relative to our nearest available technician. Evening, overnight, and weekend calls carry after-hours service considerations that daytime visits do not.
What we commit to is this: before any work begins, your technician will assess the job, explain what needs to be done and why, and give you an exact price to approve. There are no additional charges added after the fact. Questions about what a local locksmith charges, what a call-out fee covers, or how hourly time factors into your total are all things our team addresses directly on the call or on arrival — straightforward answers, no pressure. If the quoted price doesn't work for you, you're never obligated to proceed. That said, most Bexar County customers find the convenience of a same-day mobile service that comes to their address — day or night — well worth the call.
Emergency Locksmith & Mobile Lock Change — We Come to You, 24/7
An emergency locksmith situation doesn't follow business hours. A domestic situation that requires an immediate lock change, a break-in on the north side, or a property manager realizing at midnight that a former tenant never returned their key — these are real scenarios our team handles every week across Bexar County. Because we operate as a fully mobile service, there is no storefront to drive to and no appointment queue. A trained, insured technician loads up and heads directly to your location.

Frequently asked questions
What's the difference between rekeying and a full lock change — which one do I actually need?
Rekeying changes the internal pins of your existing lock so only a new key works — the hardware stays. A full lock change removes and replaces the entire lockset. If your current hardware is in good condition and you just want to invalidate old keys (after a move, a lost key, or a tenant departure), rekeying is usually sufficient and faster. If the lock is worn, damaged, or you want to upgrade security grade, a full lock change is the better call. Our technician will inspect your doors on arrival and give you an honest recommendation before any work begins.
How much does a local locksmith charge for a rekey or lock change in Bexar County?
Pricing depends on several factors: the type of lock (a standard cylindrical deadbolt differs from a mortise lock), the number of doors, whether replacement parts are needed from truck stock, the time of day, and your location within Bexar County. We don't post flat rates because your job may not be a flat-rate job. What we guarantee is a clear, exact quote — confirmed before any work starts — with no surprise charges added afterward. Call (210) 512-4768 and our dispatch team can give you an initial estimate based on what you describe.
What is a locksmith call-out fee, and does Bexar County Locksmith charge one?
A call-out fee (sometimes called a service fee or trip charge) is a base charge a locksmith applies for dispatching a technician to your location, separate from the cost of the actual labor or parts. Whether and how a call-out fee applies to your job is something our team explains clearly when you call — before you commit to anything. Factors like distance within Bexar County and time of day are part of that conversation. We believe in full transparency: every component of your quote is explained up front.
How quickly can a technician reach me for a lock change after a move or lost key?
We operate 24/7 with mobile technicians already moving throughout Bexar County, including San Antonio, Helotes, Converse, Selma, and surrounding areas. For non-emergency rekey and lock change calls, we typically aim for same-day service. For urgent situations — a lost key, a just-completed real estate closing, or a security concern — call (210) 512-4768 directly and our dispatch team will give you the most accurate arrival estimate based on technician availability in your area at that moment.
Can you rekey all my exterior doors to the same key after I move in?
Yes — this is called keyed-alike rekeying, and it's one of the most popular services we provide for homeowners who've just moved into a resale home. Instead of juggling multiple keys for the front door, back door, and garage entry, all cylinders are rekeyed to operate on one new key. It's a practical upgrade that many Bexar County property managers also use across rental units to simplify access management.
Do you handle commercial lock changes and mortise lock service for businesses?
Absolutely. Commercial lock change service is a core part of what we do — from a small retail suite needing a grade-1 deadbolt upgrade to a larger facility requiring a full commercial locksmith overhaul across multiple access points. We also specialize in mortise lock service, which is common in older commercial buildings and historic storefronts throughout downtown San Antonio. Our technicians carry commercial-grade hardware on the truck and are experienced with the higher-spec requirements that business properties demand.
