Home Rekey Service

Rekeying works by replacing the tiny pin tumblers inside your lock cylinder so that the old key no longer operates it and a new key — cut on the spot by our technician — becomes the only one that works. The lock body, hardware finish, and door prep stay exactly as they are. This is especially valuable when you have higher-end hardware already installed: a quality Schlage deadbolt or a Kwikset SmartKey unit is worth keeping. We reconfigure the internals and hand you fresh keys before we leave. Our technicians work on door knob locks, single and double-cylinder deadbolts, mortise lock assemblies, rim locks on older San Antonio properties, padlocks on gate hasps, and sliding door pin locks — virtually every residential lock type you are likely to encounter.

Mortise lock rekeying deserves special attention because these units — common on older San Antonio homes built before the 1980s and on many premium front doors installed today — are more complex than a standard cylindrical lock. A mortise lock houses its mechanism inside the door itself, and the cylinder must be extracted, re-pinned to your new key bitting, and reinserted precisely. Our technicians carry mortise-specific tooling and a broad inventory of replacement pins, so the job is handled correctly the first time without prying or forcing the door.

The most common triggers we respond to in San Antonio are post-move rekeying (landlords and sellers do not always collect every copy of a key), lost or stolen keys, domestic situations that require restricting access, and post-burglary or attempted break-in security upgrades. When a key is lost, the risk is not just that a stranger picks it up — it is that the wrong person already has it and knows your address. In those cases, this is genuinely an emergency locksmith situation, and our 24/7 availability means you are never left waiting until morning. We have responded to calls from homeowners stranded outside after a lock malfunction on Fredericksburg Road at 2 a.m. and to families who discovered a missing key set on a Sunday afternoon before the work week started — no matter the hour, the response process is the same.

If you are dealing with a full home or business lockout — standing outside your own front door with no way in — the right move is never to attempt to force entry yourself. Check for an unlocked secondary entrance, a garage side door, or a neighbor holding a spare key. If none of those options exist, call (210) 390-5404 and a trained technician will verify ownership and open the door through professional, non-destructive methods before rekeying so the situation does not repeat itself. The same applies to a child locked in a car or a pet left inside a vehicle in San Antonio's intense summer heat — those calls are treated as immediate priority dispatches.

Our residential rekeying scope covers the full range of hardware you will find on San Antonio homes. That includes: standard door knob lock cylinders, keyed deadbolts (single and double cylinder), mortise lock cartridges on both wood and steel doors, Kwikset and Schlage rekeyable cylinders, Euro-profile cylinders, sliding patio door locks, mail slot locks, storage unit padlocks, garage service door locksets, and smart lock cylinder cores where a physical key override exists. We also handle rekeying for detached garage apartments — a common configuration in older King William District properties — and guesthouses where you want separate key control from the main residence.

Beyond standard rekeying, our technicians can rekey a property to a master key system, meaning one key opens every lock on the home while each door can also have its own individual key. This is popular with multi-unit property owners and with homeowners who want to give housekeepers or dog walkers limited access. We also assist commercial locksmith clients who need office suites, storefronts, and warehouse entries brought onto a unified key plan after staff turnover — the same precision that applies to a residential mortise lock applies at the commercial scale.

We do not publish flat rates because the honest answer is that the final cost depends on several real variables: the number and type of locks being rekeyed (a basic door knob lock takes less time than a mortise lock extraction and re-pinning), the time of day or night (our 24/7 availability does mean after-hours calls carry different labor considerations), your location within the San Antonio metro and the travel distance involved, and whether any replacement parts — pins, springs, new cylinders — are needed for worn hardware. What we commit to is giving you a confirmed, exact price before any work begins. There are no surprise line items added after the job is done.

When our technician arrives, they will inspect each lock, confirm the scope with you, state the total price clearly, and only then proceed. We bring professional re-pinning equipment and a full key-cutting setup in our mobile unit, so the entire rekey is typically completed in a single visit. You walk away with tested new keys, confirmation that the old keys no longer operate the locks, and hardware that is in the same condition — or better — than when we arrived. If you have been wondering how much locksmiths charge for this type of work or what factors drive the quote, those are exactly the questions to ask when you call (210) 390-5404 — we will walk you through it before anyone leaves the shop.
