Residential Locksmith in San Antonio, TX
A residential locksmith call in San Antonio typically runs $89-$340 depending on the job, and our technicians usually arrive within 30-45 minutes for lockout calls. We’re familiar with the quirks of San Antonio’s older homes - the swelling clay soils, the original mortise hardware, the historic district rules - and we quote a flat price on the phone before the truck ever rolls. Call (877) 664-8139 and a live person will answer, 24/7.
Why San Antonio Homes Are Different
San Antonio sits on some of the most expansive Vertisol clay soils in Texas. Throughout Bexar County, these clays swell when wet and shrink when dry, and they move your house whether you notice or not. Twice a year, our phones light up with the same pattern: deep summer, when sustained 100°F heat shrinks door frames and deadbolts suddenly rattle in oversized strike pockets; then again after the first heavy fall rains, when rehydrated clay swells frames tight and throws deadbolts out of alignment. In the 78201-78210 corridor, a “broken” deadbolt is often a shifted frame. A technician who doesn’t check the strike plate geometry will sell you hardware you don’t need. Layered on top of this, the King William Historic District (78204) and Dignowity Hill (78203) carry HDRC oversight that can require locksmiths to source or replicate period-correct mortise hardware rather than simply swapping in a modern deadbolt - a combination of soil mechanics and historic preservation compliance that defines the trade here in a way no neighboring city replicates.
Residential Locksmith in San Antonio
Our Residential Locksmith team handles everything from standard rekeys to antique mortise restoration in San Antonio’s pre-1960 housing stock. The 1910s-1940s wood-frame bungalows on the West Side (78207) and the Victorian limestone homes in Dignowity Hill (78203) commonly retain original mortise locksets, skeleton-key cylinders, and cast-iron strike boxes that require specialty sourcing and antique rekeying skills rather than standard Kwikset or Schlage service.
Lock Rekey
Rekeying changes the internal pin configuration so old keys no longer work - faster and less expensive than full replacement. In San Antonio, we rekey everything from standard Kwikset deadbolts to antique skeleton-key mortise locks found in King William and Dignowity Hill. For historic homes, rekeying preserves period-correct hardware while restoring security. A standard rekey in San Antonio is $89-$140. Skeleton-key or antique mortise rekeying runs $140-$220 due to specialty pinning and parts sourcing.
Door Reinforcement
San Antonio’s clay soil cycle - summer drought shrinking frames, fall rains swelling them - gradually loosens strike plate screws and wallows out door jambs. We see this constantly in 78207 wood-frame bungalows and 78203 Victorian limestone homes. Our door reinforcement service includes longer security screws, strike box upgrades, and frame repair plates that give the deadbolt something solid to bite into. In clay-affected areas, we often reposition the strike plate and reinforce the jamb rather than replacing a perfectly good lock. Typical door reinforcement in San Antonio runs $150-$280.
Why does my deadbolt stick every fall in San Antonio?
Your deadbolt sticks every fall because San Antonio’s Vertisol clay soils rehydrate after summer drought, causing door frames to swell and misalign strike plates. The clay expands, the frame shifts, and the bolt no longer has a clear path. We fix this by repositioning the strike plate, checking frame integrity, and sometimes reinforcing the jamb - not just lubricating or replacing the lock. Call (877) 664-8139 for a free diagnosis.
Commercial Locksmith in San Antonio
Commercial locksmith service in San Antonio typically runs $150-$450 for most calls, with emergency lockout response available same day. San Antonio’s commercial buildings present unique challenges: multi-tenant properties on corridors like Fredericksburg Road or Broadway need master key systems, while historic district storefronts in King William require HDRC-compliant hardware sourcing. Our Commercial Locksmith team quotes flat prices on the phone before any truck rolls.
Master Key System
San Antonio multi-tenant buildings, property management portfolios, and mixed-use developments benefit from master key systems that balance access control with operational simplicity. We design tiered systems: a grand master for ownership, sub-masters for building managers, and change keys for individual tenants. For pre-1960 commercial buildings with original lever sets, we often retrofit master key capability into existing mortise hardware rather than replacing it, preserving both character and HDRC compliance. A new master key system in San Antonio typically costs $400-$900 for smaller buildings.
High Security Locks
San Antonio’s commercial corridors face persistent break-in risk, particularly for retail and restaurant spaces with alley access or rear doors. We install and service Medeco and Mul-T-Lock high-security cylinders with restricted keyways, drill-resistant housings, and pick-resistant pin configurations. For businesses near the River Walk or in high-traffic zones like the Pearl, we often recommend Medeco X4 systems that resist bumping and unauthorized key duplication. High-security lock installation in San Antonio ranges from $280-$550 per door, including cylinder, keys, and registration.
My commercial door lock jams seasonally - is it the lock or the foundation?
In San Antonio, it’s usually the foundation. The Vertisol clay soils beneath Bexar County shrink in 100°F summer drought, then swell after fall rainfall, racking door frames and misaligning strike plates. We test for frame shift before replacing hardware. Often a strike plate shim or jamb adjustment solves what appeared to be a “broken” lock. Call (877) 664-8139 for a free diagnosis.
Automotive Locksmith in San Antonio
A typical automotive locksmith call in San Antonio runs $89-$195 for standard car lockouts, with most resolved in 20-40 minutes. Our Automotive Locksmith team answers live, 24/7, and quotes a flat price before any truck rolls - no voicemail trees, no callbacks, no surprises on the invoice. San Antonio’s heat cycles are hard on transponder chips; sustained 100°F+ temperatures can weaken solder connections and corrupt immobilizer data.
Car Lockout Service
Locked out on Broadway near Brackenridge Park? Key trapped inside at H-E-B on Culebra? Our car lockout service in San Antonio runs $89-$145 for standard vehicles, with most calls resolved in under 30 minutes. We use non-destructive entry tools - no pry bars, no scratched paint, no damaged weatherstripping. Summer heat in San Antonio can warp older door seals, so we adjust our technique for the season.
Transponder Key Services
San Antonio’s heat cycles are hard on transponder chips. Sustained 100°F+ temperatures can weaken solder connections and corrupt immobilizer data, leaving you with a key that turns but won’t start. Transponder key programming in San Antonio runs $165-$295 depending on vehicle make and whether all keys are lost. We program on-site for most domestic and Asian brands, including vehicles with aftermarket alarm systems that complicate factory immobilizer communication.
Can you make a key for a vintage car that has no key code?
Yes. We disassemble the door or ignition lock, measure the pin heights by hand, and cut a key to that pattern. In San Antonio, we do this regularly for 1960s-1980s vehicles still on the road - the process takes 45-90 minutes and runs $195-$345. Call (877) 664-8139 to confirm we have the right blanks for your make and year.
Lock Installation & Rekey in San Antonio
Lock installation and rekeying in San Antonio runs $89-$340 depending on the hardware and labor involved, and our team typically arrives within 45 minutes for calls inside Loop 410. From the limestone vernacular homes in Dignowity Hill to the post-war bungalows stretching toward Leon Valley, we’ve learned which seasons to expect which calls. Our Lock Installation & Rekey service includes a flat price quoted on the phone before any work begins.
Smart Lock Installation
Smart lock installation in San Antonio typically runs $180-$340 for the hardware and labor, with Wi-Fi and Z-Wave models available from Schlage and Kwikset. Many homeowners in Terrell Hills and Monte Vista want keyless convenience but face a practical hurdle: their 1940s solid-wood doors are thicker than modern pre-hungs, and the bore holes don’t always align with smart lock specifications. We measure first, then quote a flat price that includes any necessary door prep.
Keypad Lock Installation
Keypad locks are the practical middle ground for San Antonio families who want code access without smartphone dependency. We install Medeco and Schlage keypad models that withstand the humidity spikes after fall rains, which can corrode cheaper electronics in outdoor applications. Pricing runs $150-$260 installed. The clay soil movement common in Bexar County means we always check door frame alignment before installing any keypad lock, preventing the seasonal binding that otherwise leads to service calls.
My deadbolt won’t throw in summer but works in winter - what’s happening?
Your door frame is shrinking in San Antonio’s summer drought, pulling the strike plate out of alignment with the deadbolt throw. This is the most common seasonal call we get in Bexar County due to Vertisol clay soil movement. The fix is usually a strike plate adjustment, not a new lock, and we can prevent recurrence with our $89 Seasonal Tune-Up. Call (877) 664-8139 for a free estimate.
Emergency Locksmith in San Antonio
Locked out in San Antonio? Our Emergency Locksmith team answers every call with a live person, quotes a flat price before the truck rolls, and typically reaches homes in the 78216-78219 corridor within 30-45 minutes.

Our phones are answered by a live person 24 hours a day, every day of the year, including nights, weekends, and holidays. No voicemail trees, no callback queues. When you are standing outside your San Antonio home at midnight, you speak to a human who can dispatch a technician immediately. We handle house lockouts, apartment lockouts, and residential gate lockouts throughout the 78216-78219 corridor and surrounding neighborhoods.
Broken Key Extraction
San Antonio’s climate cycles punish older locks. The intense summer drought shrinks wood frames and opens gaps; fall rains rehydrate the clay soils and swell frames tight against deadbolts. Keys turn against resistance, metal fatigues, and suddenly half your key is lodged in a 1930s Kwikset or a vintage Schlage mortise cylinder. We extract broken keys from all lock types without damaging the original hardware, preserving locks that may be irreplaceable in historic districts. Broken key extraction in San Antonio runs $95-$165.
What should I do if my key breaks off in the lock on a Sunday?
Call us immediately at (877) 664-8139. Do not try to extract it with pliers or glue; you will push the fragment deeper and may damage the lock. Our live operator will dispatch a technician who can extract the key and repair or rekey the lock on the spot. Estimates are free.

What San Antonio Customers Say
"Programmed a transponder key for an older car that the dealership wanted an absurd number for. Same key, fraction of the price, twenty minutes in my driveway."
- Adriana Herrera"The deadbolt had been mounted crooked by whoever lived here before and had stuck for years. He redrilled and reset it properly rather than just swapping the hardware."
- Carrie Pruitt"Got me back in and the price was fair for the hour. He arrived closer to forty five minutes than the twenty he estimated, which feels long standing outside, though he was honest that traffic was the problem."
- Todd Gallagher
