You just got the keys to your new San Antonio home — maybe a craftsman bungalow off Alamo Heights, a newer build out in Helotes, or a resale in Stone Oak — and somewhere in the back of your mind is a question worth taking seriously: who else has a copy of that key? Former owners, real estate agents, contractors, neighbors who helped with showings — the list can be longer than you think. Before you unpack a single box, the smartest move you can make is to take control of your locks.
That decision usually comes down to a rekey vs lock change, and the right answer depends on the age of your hardware, your budget priorities, and the condition of the locks already on your doors. This guide walks you through exactly what each option involves, when one clearly wins over the other, and how a professional locksmith — including work on mortise locks, deadbolts, and door knob locks — fits into the process from start to finish.
## Rekey vs Lock Change: Understanding What Each Option Actually Does
Rekeying a lock means a skilled locksmith disassembles the cylinder and replaces the internal pins so that your old key no longer works — only the new key you're handed will operate it. The lock hardware itself stays in place; only the internal tumbler configuration changes. It is faster, requires no new hardware, and is a perfectly sound security choice when your existing locks are in good mechanical condition. A rekey vs lock change comparison almost always shows rekeying as the quicker path when the goal is simply cutting off access for unknown keyholders.
A full lock change — sometimes called a lock replacement — means the existing lockset is removed entirely and a new one is installed. This makes sense when locks are visibly damaged, worn, or outdated; when you want to upgrade to a higher-security grade; when you're standardizing all doors to a single key (called keying alike); or when you're installing specialty hardware like a mortise lock for the first time. A mortise lock, which fits into a pocket cut into the door edge and is common on older San Antonio homes and commercial properties, offers significantly more strength and tamper resistance than a standard cylindrical knob lock. If your new home has aging mortise lock hardware, replacement is often the smarter investment.
## When Rekeying Is the Right Call for San Antonio Homeowners
If your locks are less than seven or eight years old, operate smoothly, show no signs of forced entry or corrosion, and are a respected hardware brand like Schlage or Kwikset, rekeying is almost certainly all you need. The goal — making every previously issued key useless — is completely achieved. This is especially true if you're moving into a home where the previous owner was simply moving on and the locks were well maintained. For most residential situations in San Antonio, a professional rekey is the fastest and most straightforward way to establish full control of your home's access.
One underrated benefit: a locksmith can rekey multiple locks to a single key in the same visit. If your front door, back door, side gate, and garage entry all use different keys right now, consolidating them to one during a rekey is simple and saves daily hassle. Rekeying also works well for tenants moving into a rental — even if the property manager swears the locks were changed, a rekey performed in your presence gives you the certainty that no outstanding copies exist. If you're ready to take that step now, call (704) 850-6756 — our team is available around the clock and can come to you anywhere in the San Antonio area.
## When a Full Lock Replacement Makes More Sense — Including Mortise Lock Upgrades
There are clear situations where a lock change is the better investment. Visible damage — a bent strike plate, a loose cylinder, a deadbolt that drags — means the lock may already be compromised and rekeying a worn-out mechanism just delays the inevitable. Older homes in neighborhoods like King William or Monte Vista sometimes have original hardware that is genuinely historic but no longer provides adequate security; replacement with a quality mortise lock can honor the architectural style while meeting modern standards.
Upgrading is also the right move when you want to add smart lock capability, high-security cylinders, or ANSI Grade 1 deadbolts that weren't part of the home before. A commercial locksmith handles these upgrades routinely on mixed-use properties, but they're equally relevant for homeowners who want the same level of protection. If there's any uncertainty about whether a lock was tampered with before you moved in — and it's worth asking your real estate agent directly — replacement removes all doubt. A professional locksmith can inspect the hardware, tell you honestly what condition it's in, and recommend the path that actually serves your security rather than just the fastest billable job.
## What to Expect During a Professional Locksmith Visit — Pricing, Process, and Verification
A common question we hear is: how much is the average locksmith charge for a rekey or replacement? There is no single honest answer because the final quote depends on several real variables: the type of lock (a standard knob lock differs considerably from a mortise lock), the number of locks being serviced, the time of day (emergency locksmith calls at 2 a.m. carry different logistics than a scheduled afternoon appointment), the travel distance to your location in the San Antonio area, and the cost of any replacement parts or new hardware. What we can tell you is that we confirm an exact up-front price before any work begins — no surprises on the invoice.
Can a locksmith make a new key from a lock? Yes — this is called impressioning or decoding, and an experienced locksmith can cut a working key directly from the lock itself without needing an original. It's a useful skill when you've moved into a home and the previous owner left you no keys at all. Similarly, can a locksmith make a key from a lock if it's a high-security cylinder? In most cases, yes, though specialty cylinders may require manufacturer-specific blanks. As for the question of whether a locksmith can get into a deadbolt — the answer is yes through legitimate, professional means after verifying ownership. Trained locksmiths do not share or use bypass techniques for unauthorized entry; the process always begins with confirming you have the legal right to access the property.
How do I know if a locksmith is legit? Look for a company that arrives in an identifiable vehicle, presents credentials before starting work, gives you a written quote before touching anything, and doesn't pressure you into unnecessary replacements. Regarding what are the requirements to obtain a locksmith license in Texas — the state requires locksmiths to be licensed through the Texas Department of Public Safety, which includes background checks and passing a written examination. You can verify a locksmith's standing through the state's online license lookup tool. Our team meets these professional standards, and we're also insured, so you're protected throughout every service call.

Frequently asked questions
Where can I find a locksmith in San Antonio who will give me an honest quote?+
The most reliable approach is to call directly, describe your specific situation — the type of lock, how many doors, and whether it's a scheduled visit or an urgent call — and ask for a confirmed price before any work starts. Factors that shape the final quote include the lock type (a mortise lock involves more labor than a knob lock), the number of locks being serviced, time of day, and travel distance within the San Antonio area. Our team provides an exact up-front price on every call before we begin, with no hidden charges added afterward.
Can a locksmith make a new key from a lock if I have no original?+
Yes. A trained locksmith can decode or impression a lock to produce a working key without needing an existing copy. This is especially helpful for new homeowners who receive a home with missing or incomplete key sets. For high-security or specialty cylinders, the process may require specific key blanks, but in most residential cases it can be handled on the same visit as a rekey or inspection. Call (704) 850-6756 and describe your hardware — we'll let you know exactly what's possible before we arrive.
How do I know if a locksmith is legitimate before I let them work on my home?+
A legitimate locksmith will arrive in a marked or identifiable vehicle, present professional credentials when asked, provide a written or verbal quote before starting any work, and never pressure you into replacing hardware you don't need. In Texas, locksmiths are required to be licensed through the Texas Department of Public Safety — you can verify any locksmith's license through the state's online portal using their name or company. Our team is insured and operates transparently on every call: you'll know the price, the scope of work, and the expected timeframe before we touch anything.
Is rekeying a lock as secure as replacing it entirely?+
When the existing lock hardware is in sound condition, rekeying provides full security — the old key is completely deactivated and only your new key works. The vulnerability rekeying does not address is the mechanical quality of the lock itself. If the hardware is worn, low-grade, or damaged, replacement with a better-quality lock — such as an ANSI Grade 1 deadbolt or a heavy-duty mortise lock — is the more secure long-term choice. A professional inspection during your service visit can tell you definitively which option your specific locks warrant.
