You finally have the keys to your new San Antonio rental — maybe a bungalow off Fredericksburg Road, a townhouse near the Pearl, or an apartment in Alamo Heights. It feels great. But before you unload a single box or spend your first night there, there is one urgent question worth asking: how many people still have a working copy of your key? Previous tenants, their relatives, a former roommate, the last maintenance contractor — the honest answer is that you probably do not know. That uncertainty is exactly why lock rekeying is the single most important thing a new renter or buyer can do before settling in.
This checklist walks you through every lock on a typical San Antonio rental — front door, back door, garage entry, mortise lock sets, smart locks, and more — so you know exactly what to rekey, in what order, and what to expect when you call a professional. It is faster and less disruptive than you might think, and it removes a real security risk on day one.
## Why Lock Rekeying Comes Before Unpacking — Not After
Rekeying a lock does not mean replacing the hardware. A trained locksmith disassembles the lock cylinder and replaces the internal pins so that the old key no longer works — only the new key you receive will operate the lock. This process preserves your existing deadbolts and knob sets, which matters in a rental where you may not have the right to swap out hardware without landlord approval. A full house lock rekey typically covers every exterior entry point in a single visit, and most experienced locksmiths complete the job in under an hour for a standard home. The result is a property that is effectively reset: whatever key history existed before you arrived is erased.
The risk of skipping this step is not theoretical. San Antonio has dense, fast-moving rental neighborhoods — think the corridors around UTSA, Southtown, and the Medical Center — where units turn over quickly and key copies accumulate over years of tenancy. A lock rekey service visit on move-in day is not an overreaction; it is the same common-sense step you would take to change a password on an account you just inherited from someone else.
## The Complete Door-by-Door Lock Rekey Checklist
Start at the front door and work your way around the entire exterior of the home. Front door deadbolt: this is your primary defense and the first cylinder to rekey. Front door knob lock or lever: many renters forget that the door knob lock below the deadbolt is a separate cylinder — both need to be rekeyed, not just one. Back door deadbolt and knob: rear entries are a frequent oversight because they feel secondary, but they are often the least observed point of entry. Side or utility door: if your unit has a third exterior door leading to a laundry room, utility closet, or side yard, add it to the list. Garage entry door: the interior door connecting an attached garage to the living space should absolutely be rekeyed — people who have a garage door code can wait out that entry point. Any French doors or sliding door secondary locks: these are less common on rentals but worth checking. Finally, if the property has a detached storage unit or a mailbox with a keyed lock, note those as well even if they are lower priority.
One lock type that deserves a dedicated conversation is the mortise lock. Common on older San Antonio homes, duplexes, and commercial-style apartment buildings, a mortise lock is a large rectangular mechanism that fits into a deep pocket cut into the door edge — as opposed to the cylindrical bores used for standard deadbolts and knob locks. Mortise locks offer excellent durability and security, but rekeying them requires a locksmith with specific experience working with mortise lock hardware. If your rental has brass or antique-style door plates with a separate keyhole and a thumb turn, you almost certainly have a mortise lock. Flag this for your locksmith before the visit so they arrive with the right tools and any compatible replacement pins or cylinders.
## Smart Lock Rekey and Code Resets — The Step Most Renters Miss
An increasing number of San Antonio landlords are installing keypad or app-connected entry systems — and this creates a different kind of access problem. A smart lock rekey does not involve pins and cylinders the traditional way; instead, it means resetting the master access code, deleting all stored user profiles, and generating fresh credentials that only you control. If your rental came with a smart lock from a brand like Schlage, Kwikset, or another manufacturer, do not assume the landlord has wiped the old tenant codes. Factory reset the device using the manufacturer procedure, or ask your locksmith to walk through it with you — many mobile locksmiths who handle smart lock rekey work carry the technical knowledge to reset popular connected lock models on-site.
Also check whether your smart lock has a physical key cylinder as a backup entry method. Many models do. That cylinder needs a traditional rekey just like any other lock, since physical backup keys may have been copied and distributed just as readily as older key sets. Combining a smart lock rekey for the digital credentials with a pin re-key for the physical cylinder is the thorough approach — and it leaves you genuinely in control of who can enter.
## What to Do If You Get Locked Out Before the Rekey Is Done
Moving day chaos is real, and lockouts happen. If you find yourself locked out of your house during the move-in process — key misplaced in a box, door that latched behind you — the right steps are: first, check every other exterior door and ground-floor window that may be unlocked; second, contact your landlord or property manager, who should have a management copy of the key; third, if neither option resolves the situation quickly and safely, call a professional emergency locksmith rather than attempting any forced entry that could damage the door or lock. Damage to a rental property entry point can cost you your security deposit and create a security gap until hardware is repaired.
For anyone wondering what to do when locked out of your house with no spare available and no landlord reachable, a 24-hour mobile locksmith is the practical answer. A skilled locksmith can verify your identity and right to access — expect to show a lease agreement, ID matching the address, or both — and then use non-destructive techniques to open the door. Pro San Antonio Locksmith operates around the clock across San Antonio and surrounding areas. If you are mid-move and something goes sideways, call (210) 390-5422 and a trained technician will be dispatched to your location.
## Understanding What Affects the Cost of a Lock Rekey Service
Pricing for a lock rekey visit is not a flat universal number — it is shaped by several legitimate variables. The type of lock matters significantly: a standard Kwikset deadbolt rekey involves different labor and parts than a mortise lock rekey or a smart lock credential reset. The number of cylinders being rekeyed in a single visit affects the total. Time of day plays a role — a same-day emergency visit at 2 a.m. carries different logistics than a scheduled morning appointment. Travel distance within the San Antonio metro also factors in for mobile locksmiths covering areas from Boerne to Converse. Any parts required — new pins, replacement cylinders, updated key blanks — are part of the final quote as well. What a reputable locksmith should always do is confirm an exact up-front price before any work begins, so you know precisely what you are committing to. If a quote is not offered clearly before the technician starts, that is a red flag worth noting.
The same pricing logic applies to automotive locksmith and commercial locksmith work. A commercial locksmith rekeying a business suite with multiple mortise lock cylinders and a master-key system is a more involved project than a single residential deadbolt, and the quote should reflect that scope. Whether the job is residential, commercial, or automotive, the right process is: describe your situation, receive a confirmed price, then authorize the work.

Frequently asked questions
Is there a 24-hour locksmith San Antonio residents can call for move-in rekeying?+
Yes. Pro San Antonio Locksmith is a fully mobile, 24-hour operation serving the entire San Antonio area. Whether you need a rekey scheduled for a weekday morning or an emergency lockout resolved at midnight, you can reach a trained technician by calling (210) 390-5422 at any hour. We dispatch directly to your address — no storefront visit required.
How much should locksmiths charge for a full house rekey?+
There is no single flat rate because the final price depends on several factors: the number of lock cylinders being rekeyed, the type of locks involved (standard deadbolt, door knob lock, mortise lock, or smart lock), the time of day, travel distance within the San Antonio metro, and whether any parts such as new pins or cylinders are needed. A trustworthy locksmith will confirm an exact up-front price before beginning any work so there are no surprises. Be cautious of any quote given without a technician first assessing the job.
What should I do if I am locked out of my house during the move-in process?+
First, check all other exterior doors and accessible ground-floor windows to see if any are unlocked. Second, contact your landlord or property manager — they should hold a management copy of the key. If neither option is available quickly, call a professional emergency locksmith rather than attempting any forced entry, which can damage the door or lock and may affect your rental deposit. Have your lease agreement and a matching photo ID ready; a professional locksmith will verify your right to access before opening the door. Pro San Antonio Locksmith is available around the clock — call (210) 390-5422.
Do I need to rekey a smart lock the same way as a traditional lock?+
A smart lock rekey involves two separate steps. First, the digital side: you or a trained locksmith performs a factory reset on the lock to wipe all stored access codes and user profiles, then sets up fresh credentials only you control. Second, most smart locks also include a physical key cylinder as a backup — and that cylinder needs a traditional pin rekey just like any deadbolt, since physical key copies may have circulated among previous tenants. Skipping either step leaves a gap. A locksmith experienced in smart lock rekey can handle both parts in a single visit.
