What we do

Mortise Lock Specialists

We repair and replace mortise locks common in older King William and Monte Vista homes, including worn cylinders and handles.

Rekey Instead of Replace

New to a home or lost a key? We rekey existing hardware so old keys stop working — often cheaper than new locks.

Door Knob & Deadbolt Upgrades

From basic door knob locks to Grade 1 deadbolts, we match hardware to how your doors are built.

Keys Made From the Lock

Lost every copy? We can decode many locks and cut a working key without the original.

What Happens When You Call for a Home Lockout Service

A home lockout rarely happens at a convenient time. You might be back from a run along the Mission Reach trail, arms full of groceries from an H-E-B run, or coming home late from the Pearl — and the key is on the kitchen counter. When you call (704) 850-6756, we ask where you are, confirm you're the homeowner or legal occupant, and dispatch the nearest mobile technician. Because our vans cover the whole San Antonio area, most lockouts get a fast local response rather than a long wait.

Before we touch your door, we quickly verify ownership. For a home lockout service, that usually means checking a photo ID with the address, a piece of mail, or a lease — it protects you and your neighbors, and it's a sign of a legitimate, professional crew. Then our goal is damage-free entry wherever the hardware allows. Many standard door knob lock and deadbolt setups can be opened without harming the door, frame, or finish, and we'll always tell you honestly if a particular lock requires a different approach.

Worried about what it costs to get back inside? The final quote depends on the type of lock, the time of day, how far we travel, and whether any parts are needed afterward. We confirm an exact up-front price before we start — no surprises once the door is open. If you're ever locked out of your house with no key at 2 a.m., know that we answer around the clock and treat late-night emergency calls with the same care as any other.

High-Security Deadbolts and Mortise Lock Upgrades Worth the Investment

Not all locks are created equal, and the thin builder-grade deadbolt that came with your house often isn't up to the job. High-security deadbolts add hardened steel inserts, pick- and drill-resistant cylinders, and reinforced strike plates that anchor into the door frame's studs rather than just the trim. For homes near busier corridors like Broadway or the areas around downtown, that extra resistance to forced entry is a meaningful upgrade — and we can walk you through options from brands like Schlage and Kwikset that fit your door and budget.

Older San Antonio homes, especially the character houses in Monte Vista, King William, and Dignowac Hill, frequently use mortise lock hardware — a sturdy, box-style lock set into a pocket cut into the edge of the door. A mortise lock can last for decades, but the internal components wear, and a mortise smart lock conversion lets you keep that classic look while gaining keyless convenience. Our technicians are experienced with mortise lock service, cylinder replacement, and matching new hardware to vintage doors so the door's heritage stays intact.

The right choice depends on your door's construction, how exposed the entry is, and whether you want keyed, keypad, or app control. We'll assess your entries in person and recommend what genuinely improves your security rather than overselling you hardware you don't need. Call (704) 850-6756 to schedule a walkthrough and we'll confirm the exact price for parts and installation up front.

Keyless Entry for Renters: Smart Locks That Don't Require Drilling

Renting near UTSA, Medical Center, or along the apartment-heavy stretches of Northwest San Antonio doesn't mean you're stuck with keys that half the previous tenants may still have. Many smart lock models replace only the interior thumb-turn and reuse the existing deadbolt, so there's no drilling, no damage to the door, and a clean reinstall of the original hardware when you move out. That makes smart lock installation realistic even when your lease forbids permanent changes.

We help renters pick keypad and app-controlled locks that offer temporary codes for dog walkers, cleaners, or visiting family, plus auto-lock features so you never leave a door unsecured. For tenants who want to stay fully reversible, we document the original setup, store any parts safely, and handle the swap in a single visit. If your landlord does allow upgrades, a mortise smart lock or a full keyless deadbolt can be a strong long-term choice.

Smart locks are convenient, but they still need good fundamentals: solid batteries, a secure strike, and a backup plan if the electronics ever fail. We configure backup keys or override codes, test every feature with you, and explain maintenance so you're never caught off guard. As an emergency locksmith service, we're also here if a smart lock ever locks you out unexpectedly.

How to Rekey a Lock After a Breakup, Break-In, or Lost Key

If you've just gone through a breakup, lost your keys, or discovered a break-in attempt, rekeying is usually faster and smarter than buying all new hardware. Wondering how to rekey a lock? The technician resets the pins inside your existing cylinder so your old keys stop working and a brand-new key takes over — the lock body stays, only the internal combination changes. Lock rekeying is ideal when the hardware is in good shape but you need to cut off anyone who might still have a copy.

Here's the short version of our process for lock rekeying at your home: we confirm ownership, remove the lock cylinders, replace or reposition the pins to match a new key, test every door with the new keys, and hand you the working set. When you want several doors to open with one key, we key them alike in the same visit. If a cylinder is damaged or corroded, we'll recommend cylinder replacement or a lock change instead — and tell you clearly why before doing it.

Searching for rekey locks near me usually means you want it done today, and we understand the urgency after a security scare. We carry common pins and keys on the van so most residential rekeys finish in one trip, and we'll confirm the up-front price based on how many locks you have and whether any parts are needed. Can a locksmith make a new key from a lock? Yes — in most cases our technicians can decode a working lock and cut a fresh key even when you've lost every copy.

Window Latches, Sliding Doors, and the Entry Points Most People Forget

Front-door deadbolts get all the attention, but intruders look for the easiest way in — and that's often a loose window latch or a sliding patio door with a flimsy factory lock. In a lot of San Antonio homes, especially single-story ranch layouts common across the North and Northwest sides, sliding glass doors are a weak point. We install auxiliary foot bolts, anti-lift pins, and secondary bars that make those doors far harder to force or wedge open.

Window locks and sash hardware wear out, paint over, or simply never worked well from the start. We replace broken window latches, add keyed sash locks on ground-floor windows, and recommend reinforcement for garage entry doors — the interior door from the garage into the house is one of the most overlooked points, often fitted with only a basic door knob lock. Upgrading that door to a solid deadbolt closes a gap many homeowners don't think about.

A full-home assessment looks at every opening, not just the obvious one. We check gate hardware, back doors, and detached structures too, and because we're a mobile commercial locksmith and residential crew, we can also advise on security cameras and lighting placement that complements better locks. Small hardware fixes add up to a genuinely harder target.

Building a Layered Home Security Plan From the Front Door Out

Good home security works in layers, and the front door is layer one. Start with a high-security deadbolt and a reinforced strike plate, then make sure the door itself is solid-core rather than hollow. From there, add keyed or keyless control that fits how your household actually lives — a busy family in Helotes with kids coming and going has different needs than a couple in a downtown loft. We tailor the plan to your doors, routines, and the realities of your neighborhood.

Beyond the entry hardware, consider keying strategy: one key for the whole house is convenient, but you may want separate keys for a rental unit, a home office, or a shed. We can key alike or key differently across your property, set up master key arrangements, and rekey everything whenever trust or access changes. Pair that with smart locks for temporary access, better window locks, and camera coverage at the main approaches, and you've built real depth rather than relying on a single device.

The best security plan is one you'll actually use and maintain. Our technicians explain how each piece works, how to keep it running, and when to call us back. When you're ready to strengthen your home, call (704) 850-6756 — we answer 24/7, bring the parts to your door, and confirm the exact price before any work starts.

Before you call — what to expect

What Customers Usually Ask Before Booking — Mortise Lock, Emergency Locksmith, and More

Can a locksmith make a new key from a lock — or make a key from a lock I already have? Yes. Our skilled technicians can decode most lock cylinders — including mortise lock hardware common in older San Antonio homes and commercial properties along Commerce Street — and cut a working key on the spot. Bring the lock or let us assess it at your door; either way, we confirm what is possible before any work begins.

How do I know if a locksmith is legit — and how do I verify the person who shows up? A straightforward way to check: the technician should arrive in a marked work van, present a photo ID on request, and be willing to explain every step of the job before touching your lock. At Pro San Antonio TX Locksmiths our team is insured, and we are happy to answer any verification questions over the phone at (704) 850-6756 before you commit to anything.

How much is the average locksmith charge — or where can I find fair pricing in San Antonio? Honest answer: there is no single flat number that applies to every job. The final quote depends on the lock or vehicle type involved (a mortise lock service differs from a simple door knob lock rekey), the time of day, travel distance within the San Antonio area, and any parts needed. What we commit to is a clear, exact price confirmed up front — so you know the full cost before we start, with no surprise additions at the end.

What are the requirements around locksmith licensing in Texas — and does your team meet them? Texas does have a regulatory framework governing locksmith work, administered at the state level. Our technicians operate in compliance with applicable Texas requirements. If you have specific questions about credentials when you call, we will answer them directly and honestly — reach us any time at (704) 850-6756.

How Our Quote Process Works — From First Call to Confirmed Up-Front Price

Step 1 — You call (704) 850-6756 and describe the situation. Tell us what you are dealing with: a residential lockout near the King William Historic District, a broken mortise lock on a commercial door, a door knob lock that needs rekeying after a move, or a car lockout anywhere in San Antonio. The more detail you share, the more accurately we can quote you.

Step 2 — We ask a few short questions to identify the right approach. Lock brand and model, vehicle make and year, address, and whether you need an emergency locksmith response or can schedule a convenient window — these details let us match the right technician and equipment to your job before anyone drives out.

Step 3 — We give you a complete quoted price over the phone. Based on lock or vehicle type, time of day, your location in the San Antonio metro, and any parts that may be needed, we state a specific total. There is no 'starting from' language here — you hear the actual number. If conditions at the site turn out to differ from what was described, we will explain any change and get your approval before proceeding.

Step 4 — You decide, then we dispatch. You are never pressured. If the quote works for you, we confirm the technician's estimated arrival window and send someone out. No work begins, and no charges are applied, until you have agreed to the price. Call now — (704) 850-6756 — we answer 24 hours a day, 7 days a week, including holidays.

What to Expect From the Technician — Residential, Commercial Locksmith, and Lockout Services

A clear arrival window, not a vague promise. When you book, we give you a realistic estimated arrival window based on your location in San Antonio and current call volume. We do not promise a number we cannot stand behind. If anything changes en route — traffic on Loop 1604 or I-10, for example — we will call you with an update rather than leave you guessing.

A marked van and a technician who identifies themselves before touching anything. Our technicians arrive in a clearly identified work vehicle and carry photo identification. Before any hands go on your door knob lock, mortise lock, or vehicle, the technician will introduce themselves, confirm the scope of work, and give you a moment to verify that the person and the quote match what you agreed to on the phone. This is standard practice on every call — lockout, rekey, or full commercial locksmith installation.

A plain-language walkthrough of the work being done. You will not be left in the dark while work happens. Whether the job is decoding a mortise lock cylinder on a historic San Antonio property, rekeying a door knob lock after a lease turnover, or an emergency locksmith response to a residential lockout in Alamo Heights, the technician will explain what they are doing and why at every stage. If they spot a secondary issue — worn pins, a misaligned strike plate — they will point it out and quote any additional work separately before touching it.

A clean finish and a working lock you understand how to use. When the job is complete, the technician removes all packaging, hardware scraps, and any debris from the work area. They will demonstrate the lock function — especially important for mortise lock hardware, which operates differently from a standard door knob lock — and confirm you are satisfied before closing out the call. Need a spare key made or have a follow-up question afterward? Call (704) 850-6756 — we answer 24/7.

Frequently asked questions

Answers to what our customers ask most. Still unsure? Just call.

How do I unlock a door if I'm locked out of my house?+

First, stay calm and check the simple options: a spare key with a trusted neighbor or family member, an unlocked back door, garage entry, or a ground-floor window you can safely reach. Avoid forcing the door or climbing anything risky, since that often causes injury or expensive damage. If nothing works, call (704) 850-6756 and a mobile technician will come to you, verify you're the occupant, and use damage-free entry wherever the hardware allows.

Is there a 24-hour locksmith in San Antonio?+

Yes. Pro San Antonio TX Locksmiths operates as a 24/7 mobile service across the San Antonio area, including nights, weekends, and holidays. Whether you're locked out of your house with no key or need an emergency rekey after a break-in, call (704) 850-6756 any time and we'll dispatch the nearest available technician.

How much is a locksmith if you get locked out?+

The honest answer is that it depends on a few factors: the type of lock, the time of day, how far we travel to reach you, and whether any parts are needed. Rather than quoting a flat figure that changes once we arrive, we confirm an exact up-front price before starting any work. That way you know the cost before we open the door.

What can I do if I'm locked out of my house?+

Check for a hidden spare, contact anyone who may have a copy, and look for a safe secondary entrance before anything else. Don't attempt to pry a door or break a window, as the repair usually costs more than the lockout call. When you need help, a trained local locksmith can get you back inside quickly and often without any damage.

How much is the average locksmith charge, and where can I find a cheap locksmith in San Antonio?+

Pricing varies by service, hardware, travel distance, and time of day, so there's no single average that applies to every job. Instead of chasing the lowest number, look for a company that gives a clear up-front quote, insured technicians, and no hidden add-ons. We provide fair, transparent pricing confirmed before work begins so you always know what you're paying.

How do I know if a locksmith is legit, and what are the requirements to obtain a locksmith license in Texas?+

A trustworthy locksmith arrives in a marked vehicle, asks you to verify ownership before opening your home, and gives a written or confirmed price before working. Texas regulates locksmith and security-service work through state requirements that typically involve background checks and registration for companies and technicians. You can always ask our team about our insurance and verify details over the phone at (704) 850-6756.

Can a locksmith make a new key from a lock?+

In most cases, yes. Our technicians can often decode a working lock and cut a brand-new key even if you've lost every copy, or disassemble the cylinder to determine the correct key. If the lock is damaged, we may recommend rekeying or cylinder replacement so your new key is reliable.

What's the difference between rekeying and replacing a lock?+

Rekeying resets the pins inside your existing lock so old keys no longer work and a new key takes over — the hardware stays. A lock change replaces the entire lock, which makes sense when the hardware is worn, outdated, or you want an upgrade like a high-security deadbolt or mortise smart lock. We'll assess your doors and recommend whichever gives you the right security for the lowest reasonable effort.
