When it comes to securing your home, your business, or your property, the locks on your doors are the most fundamental layer of protection — and the right locksmith makes all the difference. At San Antonio Surveillance, we deliver professional locksmith services in San Antonio for homeowners, businesses, property managers, and commercial facilities throughout the greater San Antonio area.
Whether you need a fresh set of locks installed in a new building, a complete rekey after a tenant move-out, a master key system designed for a multi-door facility, or high-security commercial hardware coordinated with your access control system, our experienced team has the expertise and the right equipment to deliver outstanding results. We combine traditional locksmith craftsmanship with modern security technology to give San Antonio property owners locks they can truly trust.
We’re open seven days a week from 8 AM to 7 PM CST, ready to handle scheduled installations, planned upgrades, and rekey services across the region.
It’s tempting to think of locks as a commodity — pick something up at the hardware store, screw it onto the door, and you’re done. But there’s an enormous difference between a do-it-yourself lock installation and professional locksmith service. Here’s what professional locksmithing delivers:
Proper Hardware Selection. Not all locks are created equal. We help you choose locks rated appropriately for the door, the application, the security need, and the user — not just whatever’s on the shelf.
Precise Installation. A high-end lock installed poorly is no better than a cheap one. Our team installs every lock to manufacturer specifications, with proper alignment, strike plate reinforcement, and door preparation.
Security-Grade Hardware. We work with commercial-grade hardware that far outperforms typical retail offerings — heavier construction, longer warranties, better pick resistance, and superior reliability.
Master Key Systems. Professional locksmiths design master key systems that give different users different access levels — something that’s impossible to achieve with DIY products.
Coordinated Security. Our locksmith work coordinates seamlessly with your other security systems — access control, alarm systems, intercoms, and surveillance cameras — for a unified security ecosystem.
Long-Term Value. Professional installation and quality hardware deliver decades of reliable service. DIY shortcuts often need redoing within just a few years.
Our Complete Locksmith Services
We deliver a comprehensive range of locksmith services for residential and commercial clients across San Antonio.
Residential Locksmith Services
Your home is your sanctuary, and the locks on your doors are the first line of defense. Our residential locksmith services in San Antonio include new lock installation for new construction or renovations, lock replacement and upgrades, rekey services when moving in or after losing a key, deadbolt installation and reinforcement, smart lock and keyless entry installation, sliding door and patio lock installation, garage and shed lock installation, mailbox locks, gun safe and high-security safe service, and full home security hardware assessments.
We help homeowners across San Antonio, Boerne, Helotes, Schertz, New Braunfels, and surrounding communities upgrade their home security with quality locks and professional installation.
Commercial Locksmith Services
Commercial properties have unique locksmith needs — durability, security, code compliance, and the ability to manage multiple users across multiple doors. Our commercial locksmith services in San Antonio include commercial-grade lock installation, master key system design and implementation, restricted keyway systems (keys that can’t be duplicated at hardware stores), high-security locks with pick and bump resistance, exit devices and panic bars, electric strikes and electric mortise locks, magnetic locks (maglocks) for access control integration, file cabinet and office furniture locks, and safe service for commercial cash management.
Whether you operate a single retail location, a multi-tenant office building, a warehouse, a medical practice, or a multi-site franchise, we deliver locksmith services that match your operational needs.
Master Key System Design
For businesses with multiple doors and multiple authorized users, master key systems are transformative. Properly designed master keys let you give different users different levels of access — the manager can open everything, employees can open specific areas, vendors can access only what they need. We design master key hierarchies including grand master systems, master keys, sub-master keys, and individually keyed locks — all working together as one integrated system.
High-Security & Restricted Keyway Locks
For applications where security really matters, we install high-security locks from manufacturers like Medeco, Mul-T-Lock, Abloy, Schlage Primus, ASSA, and others. These locks feature pick-resistant pin designs, bump-proof construction, drill-resistant hardened steel inserts, and patented keyways — meaning keys can only be duplicated by authorized dealers (us), not at hardware stores or kiosks. Perfect for medical facilities, financial offices, IT closets, server rooms, executive suites, and any environment where unauthorized key duplication is a risk.
Rekey Services
Rekeying changes the internal pins of existing locks so old keys no longer work — without replacing the entire lock. It’s a cost-effective alternative to lock replacement and is essential whenever:
We can rekey single locks, entire homes, or entire commercial buildings — often the same day.
Smart Lock & Keyless Entry Installation
Smart locks combine the security of professional hardware with the convenience of modern technology. We install smart locks with keypad PIN entry, Bluetooth and smartphone unlock, voice control through Alexa and Google Home, integration with home automation platforms, temporary access codes for guests and service providers, complete entry logs, and remote management from anywhere. Brands we install include Yale, August, Schlage Encode, Kwikset Halo, Level, Lockly, and others.
Access Control Hardware
Our locksmith services dovetail naturally with our access control installations. We install and integrate electric strikes, magnetic locks (maglocks), electric mortise locks, electrified panic devices, request-to-exit devices, door position sensors, and door closers — all hardware that turns ordinary doors into electronically controlled access points.
Exit Devices & Panic Hardware
For commercial buildings, exit devices and panic hardware are often required by fire code. We install code-compliant panic bars, rim exit devices, mortise exit devices, vertical rod exit devices, and electrified exit hardware — ensuring your building meets life-safety requirements while maintaining security.
Door Closers & Hardware
Beyond locks themselves, we install and service complete door hardware including hydraulic door closers, automatic door operators, hinges (including security and continuous hinges), kick plates and door protection, weatherstripping, and door reinforcement plates.
Safes & Vault Service
We install and service residential and commercial safes including home gun safes, fireproof document safes, drop safes for cash handling, depository safes for retail, jewelry and high-value safes, and small commercial vaults. We also provide safe combination changes and safe relocations.
Lock Repair & Maintenance
Locks fail over time, especially in commercial environments with heavy use. We repair and service worn locks, sticking deadbolts, malfunctioning keypads, broken keys in locks, damaged strike plates, and door alignment issues that prevent proper lock function.
Industries We Serve With Locksmith Services

The cost of locksmith services in San Antonio varies based on the scope of work and hardware quality. Basic rekey services typically start around $20-$40 per cylinder. Standard lock installations range from $75-$200 per lock plus hardware. High-security commercial lock installations can range from $200-$600+ per opening for the lock alone. Master key system design and installation for commercial properties often runs $1,500-$10,000+ depending on size and complexity. We provide free quotes with transparent line-item pricing.
Rekeying changes the internal pins of an existing lock so old keys no longer work — but the lock itself stays in place. It’s cost-effective and ideal when the lock is in good condition. Replacing a lock means installing entirely new hardware — necessary when the lock is damaged, outdated, or being upgraded to better security. We help you decide which option makes more sense based on your specific situation.
Absolutely. Master key system design is one of our specialties. We design hierarchical keying systems that let different users access different doors — managers open everything, employees open specific areas, vendors get limited access. We document the entire system and use restricted keyways so keys can’t be duplicated without authorization.
Yes. We install all major smart lock and keypad lock brands including Yale, August, Schlage, Kwikset, Level, Lockly, and others. We can also integrate smart locks with home automation platforms, security systems, and access control. For commercial applications, we install professional electronic lock systems including keypad-controlled locks and credential-based electronic locks.
Definitely. Coordinated installation is one of our biggest advantages. When you install access control with us, we handle all the related locksmith work — electric strikes, magnetic locks, electric mortise locks, panic hardware modifications, and any necessary door prep — as part of the same project. No coordinating multiple vendors.
Yes. We install high-security locks from brands like Medeco, Mul-T-Lock, Abloy, ASSA, and Schlage Primus. These locks feature pick-resistant designs, drill-resistant hardened components, bump-proof construction, and restricted keyways that prevent unauthorized key duplication. They’re ideal for medical practices, financial offices, IT rooms, executive suites, and any environment where physical security really matters.
Texas requires locksmith companies to hold a Locksmith Company License from the Texas Department of Public Safety Private Security Bureau (DPS-PSB). We operate under proper licensing and carry full insurance — every technician is credentialed, accountable, and trained to professional standards. When you hire us, you can be confident you’re working with a legitimate, properly licensed locksmith provider.
