Why Strongbox Lock & Safe Co. Is San Antonio’s Preferred Lock Installation & Rekey Company
San Antonio homeowners know the difference between a technician who shows up with a drill and one who shows up with patience. Gil Navarro built Strongbox on the principle that the person opening your locks should be the most verifiable person you’ve ever hired. Our technicians are background-checked, uniformed, and present company ID at every door in San Antonio, from Alamo Heights to the West Side.
We answer every call with a live person, 24/7, including nights, weekends, and holidays. No voicemail trees, no callback queues. The price we quote on the phone is the price on the invoice. Every job carries our 90-Day Done Right Promise, backed in writing with no extra paperwork and no arguing. If it is not right, we come back.
Our familiarity with San Antonio’s specific conditions saves homeowners money and frustration. We know the 78201-78210 corridor is dominated by pre-1960 construction with original mortise locksets, skeleton-key cylinders, and cast-iron strike boxes. We stock antique mortise cylinders and period-correct hardware because standard Kwikset deadbolts often won’t fit without modification, and in historic districts that modification can violate city code.
Our Lock Installation & Rekey Services in San Antonio
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. San Antonio’s summer heat can also stress electronic components, so we recommend models with operating temperature ratings that handle sustained 100°F days without battery drain or touchscreen lag.
Keyless Entry Systems
Keyless entry systems for San Antonio homes range from simple push-button deadbolts to full electronic strikes integrated with existing alarm systems. We install these frequently for rental properties near the Pearl District and for aging-in-place homeowners in Alamo Heights who no longer want to fumble for keys. A typical keypad deadbolt installation in San Antonio costs $140-$220. For homes with original mortise hardware, we can often retrofit a keyless trim set that preserves the exterior appearance while adding modern function, a solution we have refined specifically for San Antonio’s historic housing stock.
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. For commercial clients near Lackland Air Force Base, we often pair keypad locks with audit-trail capability, so management can track who entered and when. The clay soil movement common in Bexar County means we always check door frame alignment before installing any keypad lock, a step that prevents the “works fine in dry weather, jams after rain” calls we see from less thorough installers.
Biometric Lock Installation
Biometric locks, using fingerprint recognition, are increasingly requested by San Antonio homeowners who want maximum security without carrying anything. These units run $280-$450 installed, with options from Schlage and specialized commercial brands. The technology has improved significantly, but San Antonio’s intense summer heat creates a specific consideration: fingerprint sensors can become less responsive when direct sun heats a dark metal door to 120°F or more. We position biometric units to avoid direct western exposure when possible, and we recommend models with capacitive sensors rather than optical ones for better performance in high-heat conditions. For historic homes where exterior modification is restricted, we can install biometric locks on interior doors, such as home offices or gun safes, where HDRC oversight does not apply.

Trusted Brands We Service in San Antonio
We install and service Schlage, Medeco, Kwikset, and Abloy locks from our San Antonio-stocked inventory, which means most jobs finish in one visit without waiting for parts. Schlage and Kwikset cover the bulk of residential smart lock and keypad requests we see in neighborhoods like Tobin Hill and Beacon Hill. Medeco and Abloy come into play for homeowners who want pick-resistant cylinders or for commercial properties with specific insurance requirements. Because we keep antique mortise cylinders and period-correct strike plates on hand, we can also service the legacy hardware common in San Antonio’s pre-1960 homes without the multi-week special-order delays that send homeowners to big-box stores for incompatible replacements.
Common Lock Installation & Rekey Problems We See in San Antonio Homes
- Seasonal deadbolt binding from clay soil movement. San Antonio’s Vertisol clay soils expand and contract dramatically with moisture changes. We see a spike in “deadbolt won’t throw” calls every June and again every October, as door frames shift and strike plates fall out of alignment. The fix is usually strike plate adjustment, not a new lock.
- Original mortise locksets with no modern replacement path. The 1910s-1940s bungalows in 78207 and the Victorian-era homes in Dignowity Hill often retain mortise locksets that no standard deadbolt will fit without drilling new bore holes. We stock antique cylinders and can rekey original skeleton-key hardware to new keys.
- HDRC compliance delays in historic districts. In King William (78204) and parts of Dignowity Hill, replacing exterior hardware on contributing structures may require Historic Design and Review Commission approval. We source period-correct mortise sets and can document matching profiles to keep projects moving.
- Latch trapping after heavy rain. When Bexar County clay rehydrates after drought, door frames swell tight against latches. Rekeying alone won’t solve this; the frame needs easing or the strike mortise needs deepening before the lock will function smoothly year-round.

FAQs - Lock Installation & Rekey in San Antonio
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.
Yes, but it requires a retrofit approach rather than standard installation. King William Historic District properties often have mortise locksets that cannot accept a modern bored deadbolt without drilling, which HDRC may prohibit on contributing structures. We source smart trim sets that mount to existing mortise bodies or install smart locks on secondary doors where oversight is less strict. Call (877) 664-8139 to discuss your specific property.
Yes, we rekey antique skeleton-key cylinders for San Antonio’s pre-1960 homes, and we stock replacement mortise cylinders when the original is too worn. We rekeyed a 1910s bungalow on West Commerce Street (78207) where the original mortise lockset had a seized skeleton-key cylinder. The frame had shifted from clay swelling, so we adjusted the strike plate and sourced a replacement mortise cylinder from our antique inventory, keeping the historic look while restoring function. Call (877) 664-8139 to schedule.
San Antonio’s clay soils absorb rainfall after drought and expand, swelling wood and hollow-metal door frames against your latch and deadbolt. Rekeying or replacing the lock will not solve this; the frame needs easing or the strike mortise needs deepening. We check for this on every service call in the 78201-78210 corridor and include frame adjustment in our quote when needed. Call (877) 664-8139 for an exact diagnosis.
It depends on whether your property is a contributing structure in a historic district and whether the deadbolt is visible from the public right-of-way. Dignowity Hill has areas under HDRC oversight where exterior hardware changes require approval. We can install modern deadbolts on interior doors or secondary entrances without restriction, and for primary doors we source period-appropriate profiles that satisfy both security needs and preservation requirements. Call (877) 664-8139 and we will review your specific situation.
