Commercial Door Lock Rekey

Rekeying works by replacing the internal pin tumblers inside an existing lock cylinder so that old keys no longer operate it. For commercial properties, this means you can retain high-quality hardware — including premium mortise lock sets that are expensive to source and install — while completely invalidating any key that left your control. That matters enormously after staff turnover, a contractor relationship ends, or a master-key set goes unaccounted for. Lock rekeying is also significantly less disruptive to your daily operations than tearing out and rebuilding a door frame to accommodate new hardware.

There are situations where a change door lock service makes more sense: visibly damaged cylinders, outdated security ratings, or a landlord-required hardware upgrade. Our technicians will assess the condition and grade of your existing locks on-site and give you an honest recommendation. If your mortise lock is in good shape mechanically, rekeying it is almost always the faster, less invasive path. If the hardware is compromised or you need a higher security rating, we will walk you through door lock installation options that match your door prep and frame without guesswork.

The mortise lock is the workhorse of commercial door security in San Antonio — you will find them on hotel rooms along the River Walk, professional office suites downtown, and medical facilities throughout the Stone Oak area. Unlike a simple cylindrical knob or lever set, a mortise lock is mortised into a pocket cut in the door itself, giving it far greater structural resistance to forced entry. Rekeying a mortise lock requires disassembling the cylinder correctly and re-pinning it to a new key cut — work that demands hands-on experience with the specific cartridge design, whether it carries a Schlage, Medeco, or comparable high-security profile.

Our technicians carry a wide inventory of pins, drivers, and springs calibrated for the most common commercial mortise lock profiles found in San Antonio businesses, so same-visit service is the standard rather than the exception. If your building uses a master key system — where individual tenant keys open only assigned doors while a building manager's key opens all — we can rekey within that hierarchy without dismantling the entire system. That capability is especially valuable for property managers overseeing multi-tenant buildings along Broadway or in the Pearl district, where downtime affects multiple businesses at once.

More San Antonio businesses are adding keypad or electronic access control to their commercial doors, and rekeying those systems means something different than re-pinning a mechanical cylinder. How to change the code on a keypad door lock varies by manufacturer and model — some use a simple button sequence, others require a programming key or a connected app, and many commercial-grade units require a technician with the manufacturer's programming credentials to avoid voiding the access log. Our team handles code changes, credential resets, and access level reassignments for the keypad and electronic lock hardware installed on your commercial doors, ensuring changes are documented and every former code is fully deactivated.

If you are expanding access control — adding a new keypad station, integrating a card reader, or converting a door knob lock to an electronic lever — that falls under door lock installation and our technicians approach it as part of the same service visit when possible. We also service sliding door lock systems for businesses that use glass storefront sliders or heavy-duty commercial sliding panels, so no entry point on your property is left outside the scope of a single call. Before any work begins, we confirm an exact up-front price based on the specific hardware involved, the time of the call, travel distance to your location, and any parts required — you will never receive a surprise invoice.

Commercial lockouts and urgent security concerns do not keep business hours. A manager locked out of the office before an early morning meeting on Fredericksburg Road, a break-in attempt that damaged a cylinder at a South Side industrial facility, or a key stolen from an employee at the Pearl Farmers Market — all of these are situations where waiting until Monday morning is not an option. San Antonio Locksmith Solutions operates as a true 24-hour emergency locksmith, meaning a live dispatcher answers at (210) 401-4694 at 3 a.m. just as readily as at 3 p.m., and a trained technician is en route shortly after.

Our mobile setup means we come to you with the tools and parts needed to rekey, repair, or replace hardware on the spot — no towing your door to a shop. We carry equipment for damage-free entry when a lockout allows it, protecting your door frame, glass, and hardware from the kind of pry damage that creates a second repair bill. Ownership or authorization verification is part of our standard process for all commercial calls, so you can trust that the same professionalism protecting your property tonight is what protects every other San Antonio business we serve.
