Rekeying & Door Knob Locks

Rekeying is the process of replacing the driver pins and key pins inside a lock cylinder so that only a new key will operate it — the old key becomes permanently useless. This is the right move any time you buy or rent a property, after a roommate moves out, following a break-in attempt, or whenever you lose a key and cannot account for every copy. Because the cylinder hardware stays in place, rekeying is faster than a full lock replacement and involves zero damage to your door or frame. Our technicians carry pinning kits compatible with the most common residential and commercial cylinders on the market, including Schlage and Kwikset, and can rekey multiple locks to a single master key in one visit — a feature apartment owners across the South Side especially appreciate during tenant turnover.

The same logic applies to deadbolts. A door knob with lock alone is not a complete security package; deadbolts add a second, longer bolt that resists kick-in force significantly better than a spring latch. We routinely rekey both components during the same appointment and, when requested, reconfigure them to operate on one unified key. If your existing deadbolt cylinder is worn, corroded from San Antonio's humidity, or simply too old to repin safely, we will tell you honestly and recommend a replacement that fits your door prep without requiring new boring.

A mortise lock is a different animal from a standard cylindrical knob set. Instead of a simple bored hole, it requires a deep rectangular pocket routed into the door edge to house a multi-function lock body that typically integrates the latch, deadbolt, and sometimes a privacy or passage function into one unit. Older San Antonio craftsman bungalows — particularly those in Monte Vista and Monticello Park — were built with mortise locks as standard hardware, and many of those original units are still in service. Our technicians are experienced in both servicing antique mortise lock bodies and installing modern replacements that match the original mortise pocket dimensions.

For commercial applications, a mortise lock is often the code-compliant choice for high-traffic doors because the body is recessed and far less exposed to wear than a surface-mounted cylindrical lock. Our commercial locksmith work covers office suites, retail storefronts, warehouses, and multi-tenant buildings throughout San Antonio. We assess strike plate alignment, door clearance, and frame reinforcement before recommending any hardware, because a quality mortise lock installed in a weak frame is only as good as the wood around it. If you need a commercial locksmith who understands the full picture — hardware, frame, and cylinder — call (210) 390-5422 and we will schedule a same-day evaluation.

Not every door knob with lock serves the same purpose, and the wrong choice creates either a security gap or an unnecessary inconvenience. Here is how we guide San Antonio customers through the decision. A standard keyed knob handles most interior and light-duty exterior applications, but for a front entry door it should always be paired with a separate deadbolt. A double lock door knob — one that locks from both sides with a key — is useful for doors connecting a garage to a living space, because it prevents someone who has entered the garage from simply turning a thumbturn to get inside. A smart lock door knob adds Wi-Fi or Z-Wave connectivity so you can grant and revoke access remotely, check entry logs, and integrate with home automation — genuinely useful for Airbnb hosts and multi-property owners throughout the greater San Antonio market. A keypad lock door knob eliminates physical keys entirely, relying instead on a PIN code; ideal for households with children or staff who routinely lose keys. For a door knob with lock for bedroom or in-law suite use, a simple privacy lock — push-button or turn-button on the inside — is usually the appropriate grade rather than a keyed function.

Our technicians will walk you through the grade rating (ANSI Grade 1, 2, or 3), the cylinder quality, and whether the lock you are considering is realistically pick-resistant for your threat environment. We stock a range of hardware and can also install customer-supplied product. Factors that determine your final quote include the lock type and grade, the number of cylinders being keyed, the time of day you call, travel distance within the San Antonio metro, and whether any door prep modification or reinforcement hardware is needed. We confirm the full price before we begin — no surprises on the invoice.

A locked-out call is one of the most common requests we receive, whether it is a homeowner who left their keys on the kitchen counter or a business owner who arrived at their Commerce Street storefront before the office manager with the spare. As your emergency locksmith in San Antonio, we are dispatched 24 hours a day, seven days a week, and our mobile units are already spread across the city so response times stay practical at 2 a.m. on a Tuesday as well as at noon on a Saturday. Before you call, it is worth checking all ground-floor windows you know are unsecured, asking a co-habitant or neighbor who may have a spare, or contacting your building manager if you are in an apartment — all legitimate, damage-free first steps.

We want to be direct about one thing: if you have searched for how to pick a door knob lock or how to pick a lock door knob, the internet is full of tutorial content — but attempting to pick or bypass a lock yourself without proper tools and training typically results in a broken plug, a snapped pick stuck in the keyway, or damage to the cylinder that turns a simple lockout into a full lock replacement. Our technicians open locked doors through legitimate, professional methods that are damage-free where the lock and door condition allow, and we verify ownership before any work begins. For a car lockout, child locked in a vehicle, or any situation where safety is at immediate risk, call (210) 390-5422 right now — we answer every call, every hour.

Pro San Antonio Locksmith is not a single-service operation. Our mobile technicians handle automotive locksmith work — cars, trucks, and motorcycles — covering transponder key programming, ignition repair, and car lockouts across every major make on Texas roads. On the residential side, we handle everything from a basic door knob lock rekey to full mortise lock installation on historic properties. On the commercial side, our commercial locksmith services extend to panic hardware, access control integration, master key system design, and high-security cylinder upgrades for businesses that need accountability over who holds which key at any given time. If you have ever wondered whether there is a 24-hour locksmith in San Antonio equipped to handle all three categories in a single call — the answer is yes, and the number is (210) 390-5422.

Questions about cost are common and fair. How much should locksmiths charge? The honest answer is: it depends on the work. A straightforward residential rekey during daytime hours costs less than an emergency commercial lock replacement at midnight, because the factors involved — parts, complexity, time of day, and travel — are genuinely different. We do not apply surprise fees after the fact. The quote you receive before we start is the price you pay. As for questions like how much does pop a lock cost or where can I get a cheap car key replacement in San Antonio — we encourage you to call us directly for an exact, no-obligation quote rather than rely on ballpark figures you read online, which rarely reflect the actual variables of your specific situation.
