Why Strongbox Lock & Safe Co. of San Antonio Is Alamo Heights’s Preferred Residential Locksmith Company
We’ve worked in Alamo Heights long enough to recognize the difference between a Corbin and a Russwin cylinder by feel. That matters here.

Our Residential Locksmith Services in Alamo Heights
Lock Rekey
Rekeying is our most common request in Alamo Heights, and it rarely involves a standard pin-tumbler cylinder. We regularly rekey 1940s Corbin mortise locks, aged Russwin deadbolts, and even original skeleton-key mechanisms so they work with a modern key while preserving the hardware. A typical lock rekey in Alamo Heights runs $45-$85 per cylinder for standard hardware, and $95-$175 for antique or mortise lock rekeying requiring specialty pins or fabrication. We recently worked on a Tudor Revival home on Elsmere Place where the original 1930s mortise lock had a broken spring, causing the latch to stick. We sourced a period-correct Corbin spring and rekeyed the cylinder to match the homeowner’s smart lock system - a common hybrid fix in this preservation-minded enclave.

Deadbolt Installation
Installing a deadbolt in an Alamo Heights home demands more than drilling a hole. Many exterior doors here were built for mortise locksets, not modern bored-in deadbolts. Forcing a standard deadbolt into an original mortise pocket damages the door’s structural integrity and destroys the aesthetic. We assess the door construction first - solid wood, stile-and-rail, or composite - then recommend either a properly fitted single-cylinder deadbolt or a mortise deadbolt that respects the original architecture. Typical deadbolt installation in Alamo Heights costs $125-$225 for standard bored-in models, and $195-$350 for mortise deadbolts or high-security installations requiring door modification. We install Schlage, Medeco, and Mul-T-Lock deadbolts with the right strike plate and jamb reinforcement for each door’s age and condition.

Door Reinforcement
San Antonio’s expansive clay soils cause significant seasonal foundation movement, and in Alamo Heights’s older homes this routinely shifts door frames enough to bind deadbolts or misalign strike plates. Door reinforcement addresses this at the source: we install heavy-duty strike plates with 3-inch screws reaching the framing, add door jamb armor where the wood has aged or split, and adjust or replace hinges that have sagged from decades of use. A standard door reinforcement package in Alamo Heights runs $150-$275 per door. For homes with chronic seasonal binding, we also diagnose whether the issue is the lock or the frame shift - preventing unnecessary lock replacement.

Lock Change
When a lock in Alamo Heights truly needs replacement, we stock hardware that fits the home rather than forcing the home to fit whatever is on the truck. That means period-appropriate mortise locksets for restoration projects, high-security cylinders for estate properties, and smart locks that integrate with existing key systems. A standard lock change in Alamo Heights costs $85-$165 per door for quality residential hardware. Antique replacement or specialty mortise lock sourcing runs $200-$450 depending on rarity and lead time.

Residential Lockout
Lockouts in Alamo Heights often involve unique entry points: side gates with original wrought-iron locks, carriage-house doors, or main entries with double-cylinder deadbolts installed decades ago. Our emergency lockout response to Alamo Heights averages 25 minutes, and we open locks without drilling whenever possible - preserving irreplaceable hardware. Residential lockout service in Alamo Heights is typically $75-$125 during standard hours and $125-$175 for nights, weekends, or holidays.

Window Lock
Original casement and double-hung windows in Alamo Heights’s 1920s-1950s homes often have damaged or missing sash locks, or no locks at all. We source and install period-correct window locks that maintain the home’s character while meeting modern security expectations. Window lock installation or repair in Alamo Heights generally runs $35-$75 per window for standard hardware, with custom or hard-to-find reproduction locks at $85-$150.

Trusted Brands We Service in Alamo Heights
We install and service the full range of premium security hardware - Schlage, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, Kwikset, and Sargent - so the right lock goes on the right door. For Alamo Heights’s heritage homes, we maintain a local inventory of Schlage and Baldwin mortise lock components, plus access to specialty suppliers for discontinued Corbin, Russwin, and Sargent cylinders. That stock means faster turnaround on repairs that would otherwise require weeks of parts hunting. For modern security upgrades, we carry Mul-T-Lock and Abloy high-security cylinders and smart lock systems that integrate with existing keyways - a common request in the estate homes along Castano Avenue and Viesca Street.
Common Residential Locksmith Problems We See in Alamo Heights Homes
- Forced modern deadbolts into original mortise pockets. Out-of-area locksmiths often drill standard deadbolt holes into stile-and-rail doors built for mortise locksets, splitting the wood and destroying the door’s structural integrity. We see this repair call monthly in Alamo Heights, and the fix usually requires custom woodwork plus correct hardware installation.
- Seasonal deadbolt binding misdiagnosed as lock failure. San Antonio’s clay soils shift door frames throughout the year. A deadbolt that sticks in July may work perfectly in January. We check frame alignment and strike plate position before recommending lock replacement - saving homeowners unnecessary expense.
- Wrought-iron gate locks replaced against owner wishes. Many estate homes along Broadway and interior streets have original decorative gate hardware that owners want preserved. Replacing these with modern cylinders destroys the aesthetic. We fabricate or source obsolete skeleton-key and warded lock components instead.
- Smart locks installed without assessing door condition. Original 1920s doors in Alamo Heights may lack the structural integrity or thickness for modern smart lock hardware. We evaluate the door first, then recommend appropriate hardware or necessary reinforcement - never a one-size-fits-all installation.

FAQs - Residential Locksmith in Alamo Heights
Yes. We regularly rekey vintage Corbin and Russwin mortise cylinders to operate with modern smart lock systems, creating a single key that works both the original hardware and the new electronic entry. This hybrid approach is common in Alamo Heights’s preservation-minded homes. The work typically runs $125-$225 depending on cylinder condition and smart lock brand compatibility. Call (844) 697-1013 to discuss your specific hardware - estimates are free.
San Antonio’s expansive clay soils shift your home’s foundation seasonally, and in Alamo Heights’s older brick and limestone structures this commonly misaligns door frames enough to bind deadbolts against strike plates. Extreme summer heat (100°F+) also expands aluminum and composite door frames, causing additional cylinder sticking. We diagnose whether the issue is frame shift or lock wear, then adjust or reinforce rather than replace unnecessarily. Seasonal adjustment service in Alamo Heights typically costs $75-$150. Call (844) 697-1013 for a free assessment.
Yes. Many estate homes along Broadway and interior streets have decorative wrought-iron gate locks that owners refuse to replace for aesthetic reasons. We fabricate or source obsolete skeleton-key and warded lock components rather than installing modern cylinders that clash with the original design. Restoration costs range from $150-$350 depending on part availability and fabrication needs. Call (844) 697-1013 - we can often assess the lock from photos before visiting.
It can be, but only after assessing the door’s structural integrity, thickness, and hinge condition. Original 1920s doors in Alamo Heights may lack the mass or solid construction required for modern smart lock hardware, and improper installation can split aged wood or cause premature failure. We evaluate each door individually and recommend appropriate reinforcement or alternative mounting solutions when needed. Smart lock installation with assessment runs $195-$375 in Alamo Heights. Call (844) 697-1013 for a free evaluation.
Every 2-3 years for homes with original hardware still in daily use. Alamo Heights’s 1920s-1950s homes often retain mortise locksets with internal springs and mechanisms that wear gradually - not dramatically, but cumulatively. Our $89 seasonal tune-up includes lubrication, spring tension check, strike plate alignment assessment, and early wear identification before a small issue becomes a lockout or hardware failure. For homes with mixed original and modern systems, annual inspection prevents compatibility problems. Call (844) 697-1013 to schedule.
