Whether you're securing a craftsman bungalow off Alamo Heights, a retail storefront on the San Pedro corridor, or a multi-unit property near UTSA, the quality of your door hardware matters far more than most people realize — and a poorly installed or worn-out deadbolt is often the easiest thing a burglar looks for.

Deadbolt Installation San Antonio: What the Job Actually Involves
A proper deadbolt installation is not just a matter of sliding a new lock into an existing hole. Our technicians evaluate the door thickness, frame condition, strike plate depth, and existing bore diameter before recommending a lock grade or style. In older San Antonio homes — particularly those built before the 1980s in neighborhoods like Monte Vista or King William — door frames can be narrower or softer than modern standards, which affects which locks will hold under force. We bore new holes when needed, reinforce strike plates with 3-inch screws into the stud for kick-in resistance, and test throw-and-retract action before we call the job done. Where the existing door and frame allow, we always aim for a damage-free installation process.
We install a full range of deadbolt types: standard single-cylinder deadbolts, double-cylinder deadbolts (keyed on both sides), jimmy proof deadbolt installation for outswing and apartment-style doors, and keypad or smart deadbolts that integrate with home automation systems. Jimmy proof deadbolts are particularly well-suited to metal doors and rental units because they interlock with the door frame in a way that resists prying far better than a conventional surface-mounted rim lock. If you've been searching for deadbolt installation near me and want a technician who will actually explain the difference between a Grade 1 and Grade 3 lock before charging you anything, call (210) 640-1899 — we answer every call, day or night.
Mortise Lock Repair and Replacement: The Heavy-Duty Standard
A mortise lock is the gold standard for commercial and high-traffic doors, and it's increasingly popular for upscale residential applications in San Antonio. Unlike a standard cylindrical deadbolt that fits into a drilled bore hole, a mortise lock sits in a deep rectangular pocket cut into the door edge, combining the deadbolt and latch into one heavy-duty cartridge. This gives it superior strength and a cleaner aesthetic — but it also means installation and repair require real skill and the right tools. Our technicians are experienced with mortise lock bodies from manufacturers like Schlage, Kwikset, and Baldwin, and can replace worn mortise cases, repair broken cam mechanisms, and re-key mortise cylinders without replacing the entire unit when that's the smarter call.
For commercial locksmith work especially, a functioning mortise lock is non-negotiable. Restaurant owners on the River Walk, property managers in the Medical Center district, and office building superintendents throughout downtown San Antonio routinely call us when a mortise lock starts dragging, misfiring, or simply fails after years of heavy use. We carry a range of mortise components in our service vehicles so most repairs can be completed in a single visit. If a full replacement is needed, we'll tell you that upfront — along with the exact price — before we touch anything.
Emergency Locksmith Response: Locked Out, Lock Failure, and Urgent Repairs
A deadbolt that suddenly won't turn, a key snapped off inside the cylinder, or a door that won't latch after a break-in attempt — these are not situations where you can wait until morning. As a 24/7 emergency locksmith serving San Antonio and surrounding communities, Trusted San Locksmith keeps mobile units rolling around the clock. Whether you're locked out of your home at 2 a.m. near Loop 1604, dealing with a forced-entry damage repair after an incident in the Southside, or running a business that discovered a failed lock on the first employee to arrive — we respond fast and we come to you.
We also handle door knob lock repairs and replacements alongside deadbolts, because in most residential and light commercial settings, the knob lock and deadbolt work as a system. Replacing one while leaving a failing knob lock in place is a short-term fix at best. Our technicians assess both mechanisms together and give you an honest recommendation on whether to repair, rekey, or replace. If you're locked out of your car and reached this page by accident — we handle that too. Our automotive locksmith services cover cars, trucks, and motorcycles throughout San Antonio, including situations involving child locked in car emergencies where we prioritize immediate dispatch. Call (210) 640-1899 any time.
Choosing the Right Deadbolt: Grades, Brands, and What Fits Your Door
Not every lock sold at a hardware store is appropriate for every door, and marketing language on lock packaging is not always a reliable guide to real-world security. ANSI grading tells a clearer story: Grade 1 locks are the highest residential and commercial standard, rated for hundreds of thousands of cycles and significant kick force; Grade 2 is mid-range and appropriate for interior and lower-traffic doors; Grade 3 offers minimal resistance and is generally unsuitable as a primary deadbolt. Our technicians will show you physical examples and explain what grade is appropriate for your specific entry point.
We work with trusted hardware brands including Schlage, Kwikset, Medeco, and others, and we stock a variety of finishes — satin nickel, oil-rubbed bronze, matte black — so your new lock doesn't clash with existing hardware. For businesses, we can integrate deadbolts with access control systems, including keypad and electronic strike setups. For homeowners interested in smart locks, we handle the full installation including door prep, app configuration guidance, and backup key cylinder setup so you're never truly locked out due to a dead battery. Our goal on every job is to match the right hardware to the actual use case — not to upsell a product you don't need. Our services cover the full range of lock needs: single-cylinder deadbolt installation, double-cylinder deadbolt installation, jimmy proof deadbolt installation on outswing doors, mortise lock installation and repair, mortise cylinder rekeying, smart deadbolt installation and programming, keypad deadbolt setup, Grade 1 high-security lock upgrades, strike plate reinforcement with deep-set screws, door frame repair after forced entry, door knob lock replacement, door knob lock repair, commercial deadbolt installation for storefronts, office suite deadbolt upgrades, multi-point locking system service, master lock deadbolt installation and replacement, deadbolt rekey without full replacement, broken key extraction from deadbolt cylinders, lock lubrication and cylinder maintenance, sliding door deadbolt and pin lock installation, garage entry door deadbolt installation, apartment and rental unit lock change, Airbnb and short-term rental lock changeover service, access control deadbolt integration, and emergency deadbolt repair after break-in attempts.
What Determines the Cost of a Deadbolt Installation or Repair
We don't publish flat-rate prices because the honest answer is that the final cost depends on several real variables: the type and grade of lock being installed or repaired, the condition of your existing door and frame, the parts needed, the time of day or night the call comes in, and how far our nearest technician needs to travel to reach you. A straightforward single-cylinder deadbolt swap on a standard interior residential door will have a different price point than a full mortise lock replacement on a steel commercial door at 3 a.m. That's not a dodge — it's just how skilled trade work is priced fairly.
What we commit to without exception is this: before any work begins, your technician will give you a complete, itemized price. You approve it or you don't — there is no pressure and no surprise line items on the invoice afterward. Customers sometimes ask how much locksmiths should charge and whether there's a standard rate. The short answer is that a fair price reflects the skill, tools, response time, and parts involved — and a technician who quotes blindly over the phone without assessing the job is either guessing or padding. We assess first, quote second, work third.

Frequently asked questions
Is there a 24-hour locksmith in San Antonio for deadbolt emergencies?+
Yes — Trusted San Locksmith operates 24 hours a day, 7 days a week, including holidays. Whether your deadbolt has failed in the middle of the night, you've been locked out of your home after a late shift, or a break-in attempt has left your door frame damaged and unsecured, we dispatch trained, insured mobile technicians to your location at any hour. Call (210) 640-1899 and you'll reach a live team member every time — not a voicemail.
What is a jimmy proof deadbolt and do I need one?+
A jimmy proof deadbolt, also called an interlocking rim deadbolt, mounts on the interior surface of the door and uses interlocking vertical bolts that engage with a strike plate bolted directly to the door frame. Unlike a traditional deadbolt that throws a bolt horizontally into the frame, the jimmy proof design resists prying forces by physically interlocking rather than just extending. It's particularly effective on outswing doors, metal doors, and apartment or rental unit entry points where the door swings away from the frame. Our technicians can assess your door and tell you on-site whether a jimmy proof deadbolt installation makes sense for your specific situation.
How much does deadbolt installation or repair cost in San Antonio?+
There is no single flat answer because the price depends on real variables: the type and grade of lock involved, whether the door needs new boring or frame reinforcement, the parts required, the time of day, and travel distance to your location. What we guarantee is that your technician will assess the situation first and give you a complete, confirmed price before any work starts. You will never receive a surprise charge after the job. If you're wondering how much locksmiths should charge in general, a fair rate reflects skilled labor, proper tools, response time, and quality parts — all of which we provide transparently.
Can you install a mortise lock on a residential door, or is it only for commercial properties?+
Mortise locks are absolutely appropriate for residential use and are actually a popular upgrade for homeowners who want superior security and a more refined look. Because a mortise lock body sits inside the door edge rather than protruding from it, it creates a cleaner profile and is significantly harder to defeat with kick-in or prying attacks than a standard bore-hole deadbolt. Our technicians handle mortise lock installation and repair on both residential and commercial doors throughout San Antonio. If your current door requires routing for a mortise pocket, we handle that as part of the installation process.
How do I know if my deadbolt needs repair or full replacement?+
Common signs that a deadbolt needs attention include: the key requiring extra force or a specific wiggle to turn, the bolt not throwing all the way or retracting sluggishly, visible corrosion or damage on the cylinder face, loose mounting screws that won't stay tight, or a lock that was installed more than 10 to 15 years ago and has seen heavy use. Sometimes a repair — re-pinning a cylinder, lubricating internal components, or tightening the strike plate — is all that's needed. In other cases, especially after a forced-entry attempt or if the lock is a low-grade model, full replacement is the smarter investment. Our technicians will give you an honest assessment and never recommend replacement when a repair will genuinely do the job.
Do you handle car lockouts and child-locked-in-car emergencies as well as residential deadbolts?+
Yes. While our deadbolt installation and repair work covers homes and businesses, Trusted San Locksmith is a full-service mobile locksmith operation. We respond to automotive lockouts across San Antonio for cars, trucks, and motorcycles, and we treat child locked in car calls as priority dispatches. If you have a lock emergency of any kind — residential, commercial, or automotive — call (210) 640-1899 and we will get the right technician moving toward your location immediately.
