Deadbolt Installation
San Antonio homes face real security challenges — from high-traffic corridors like Loop 410 to quiet residential streets in Alamo Heights and Stone Oak. A deadbolt is still the single most effective mechanical barrier between your family and an unauthorized entry, but only when it is the right grade, correctly fitted, and properly aligned with your door frame. At Pro San Antonio Locksmith, our trained, insured technicians assess your specific door setup before recommending any hardware, so you never end up paying for a lock that does not match your security needs or door thickness.

Why a Professional Deadbolt Installation Makes the Difference
A deadbolt is only as strong as the installation behind it. An improperly drilled bore hole, a misaligned strike plate, or a shallow mortise cut can make even a Grade 1 lock far easier to defeat than the manufacturer ever intended. Our experienced technicians measure door thickness, check frame integrity, and confirm that the lock's bolt throw extends far enough into the jamb to resist kick-in force — a concern especially relevant in older San Antonio craftsman homes where door frames have settled over decades. We also verify that weather exposure common in South Texas summers has not warped the door stile enough to affect latch alignment, which is a silent vulnerability most homeowners never notice until a lock fails at the worst possible moment.
We handle a full range of hardware types on every service call: single-cylinder deadbolts, double-cylinder deadbolts, keypad and smart deadbolts, jimmy proof deadbolt installation on outward-swinging doors, mortise lock systems for thicker commercial doors, and door knob lock combinations for layered residential entry points. We stock popular Schlage, Kwikset, and Yale hardware on our service vehicles, and we can also install customer-supplied hardware when it meets minimum security standards for the door type.
Mortise Lock and Commercial Locksmith Services — Built for Heavier Duty
For commercial properties — storefronts along Broadway, office suites in the Pearl District, or warehouses near the Port San Antonio complex — a standard cylindrical deadbolt rarely provides sufficient protection. A mortise lock sits recessed inside the door body itself, giving it a mechanical advantage that surface-mounted locks simply cannot match. Our commercial locksmith team installs, re-keys, and upgrades mortise lock systems on steel, aluminum, and solid-wood commercial doors, including paired with panic hardware and ADA-compliant lever sets where required.
Commercial deadbolt installation also involves master-key systems, restricted keyways, and high-security cylinders that resist picking, drilling, and bumping. If your San Antonio business currently relies on builder-grade hardware that came with the building, an upgrade consultation costs you nothing but a phone call. Reach us any time at (210) 390-5422 — we answer 24/7 and can schedule a commercial site assessment at a time that does not disrupt your business hours.
Deadbolt Installation for Every Residential Scenario in San Antonio
Residential needs vary widely across the city. A door knob lock paired with a deadbolt is standard for most interior-facing garage-access doors in neighborhoods like Shavano Park or Dominion. A double-cylinder deadbolt — requiring a key on both sides — is often chosen for doors with glass panels where a burglar could otherwise break the glass and reach a thumb-turn. Smart deadbolts with Z-Wave or Bluetooth connectivity suit homeowners who want keyless entry and remote monitoring without replacing their entire lock system. Our technicians walk you through the trade-offs of each configuration so the final choice is yours, made with full information.
We also handle mortise lock replacements on older San Antonio homes where the original Victorian or Craftsman-era hardware has worn out but the homeowner wants to preserve the door's period character. In those cases, we source period-compatible escutcheons and work damage-free wherever structurally possible, avoiding unnecessary cuts or patches to original woodwork. If you are adding a second lock to an existing door, we pre-drill and chisel the mortise pocket cleanly so the finished result looks factory-fitted, not aftermarket.
Emergency Locksmith Response, Lockouts, and Upgrade Timing
Sometimes a deadbolt upgrade is not planned — it follows an emergency. A lock that has been tampered with, a door frame that shows fresh damage, or a key that broke off inside the cylinder are all situations where you need an emergency locksmith response, not a scheduled appointment three days away. Our mobile units operate across Bexar County continuously, meaning a technician can typically reach most San Antonio neighborhoods within a short drive regardless of the hour.
If you are locked out of your home or business and you suspect the lock itself has been compromised, do not attempt to force entry. Check for a spare key with a trusted neighbor, try an alternate entry point you control, or call us at (210) 390-5422 to verify your identity on-site and open the door without damage wherever the lock condition allows. Once inside, we immediately assess whether the existing hardware is salvageable or whether a same-visit deadbolt replacement is the safer choice. We confirm an exact up-front quote before any hardware work begins — the final figure reflects the lock type selected, time of service, and travel distance to your address, with no hidden fees added after the fact.
Automotive Locksmith Services — Cars, Trucks, and Motorcycles San Antonio
Pro San Antonio Locksmith is not limited to doors and deadbolts. Our mobile team also responds to vehicle lockouts, key replacements, and ignition issues across San Antonio for cars, trucks, and motorcycles. If you are locked out of your car in a parking garage on the River Walk or stranded in a lot near the AT&T Center after an event, we come to you. Child locked in a car is treated as a priority dispatch — call (210) 390-5422 immediately and stay on the line; our nearest technician will be routed to you while you remain with the vehicle.
Car key replacement for modern transponder and smart-key vehicles involves programming, not just cutting, and our technicians carry the diagnostic equipment needed for a wide range of domestic and import makes. The factors that determine your final quote include the vehicle make, key type, any programming fees tied to the security system, and travel distance. As with all our services, we state the exact price before beginning so there are no surprises. We cover motorcycles and light trucks as well, making us a genuinely full-service automotive locksmith option for the greater San Antonio area.
Frequently asked questions
Answers to what our customers ask most. Still unsure? Just call.
Is there a 24-hour locksmith in San Antonio for deadbolt installation?+
Yes — Pro San Antonio Locksmith operates 24 hours a day, 7 days a week, including weekends and holidays. Whether you need a deadbolt installation at 2 a.m. after a break-in attempt or a scheduled upgrade on a Sunday afternoon, our mobile technicians cover the full San Antonio metro area and arrive with the hardware and tools to complete most jobs in a single visit. Call (210) 390-5422 any time and a live team member will answer.
How much should locksmiths charge for deadbolt installation?+
Pricing depends on several factors: the grade and brand of lock being installed, whether the door requires new boring or only a direct replacement, the time of day the work is performed, and the travel distance to your address. A basic single-cylinder swap on a pre-bored residential door costs less than a full mortise lock installation on a commercial-grade steel door, for example. At Pro San Antonio Locksmith we provide an exact up-front quote before any work begins so you know the complete total in advance — no estimates that grow after the job is done.
What is a jimmy proof deadbolt and when do I need one?+
A jimmy proof deadbolt installation is the right choice for outward-swinging doors — common on apartment units, back porches, and some commercial entries — where a conventional surface-mounted deadbolt bolt could be defeated by prying the door away from the frame. A jimmy proof deadbolt uses interlocking vertical bolts that engage the strike plate from above, making pry attacks largely ineffective. Our technicians assess whether your door swing, frame material, and existing hardware make this style the best fit before recommending it.
How much does Pop A Lock cost, and how is Pro San Antonio Locksmith different?+
We are not affiliated with any franchise or third-party network, so we cannot speak to what another service charges. What we can tell you is that our pricing is based on transparent factors — lock type, time of service, travel, and parts — and we confirm the exact amount before touching your door or vehicle. Our trained, insured technicians carry professional-grade equipment and stock a wide range of Schlage, Kwikset, and Yale hardware on our vehicles, which means fewer delays and a cleaner finish than a technician who has to order parts separately.
Can I get a cheap car key replacement in San Antonio, and do you do that too?+
We understand cost is a real concern when a key issue catches you off guard. We do not use bargain vocabulary to describe our pricing, but we do believe in transparency: before any car key replacement or programming begins, we give you the exact total so you can make an informed decision. Factors include the vehicle make and model, whether the key requires transponder programming or proximity-fob syncing, and travel distance. Call (210) 390-5422 and our team can give you a firm quote over the phone for most common vehicle types.
Do you install mortise locks on residential doors, or only commercial properties?+
We install and service mortise lock systems on both residential and commercial doors throughout San Antonio. On the residential side, mortise locks are especially common in older homes in neighborhoods like Monte Vista or King William where original door hardware was built into the door body rather than surface-mounted. We source period-compatible trim pieces where available and work damage-free on original woodwork wherever structurally possible. On commercial properties, we pair mortise lock bodies with restricted keyways and high-security cylinders for enhanced control over who holds a working key.
