Locked Out of Your House With No Key? Here's What Our Emergency Locksmith Actually Does

The first thing our emergency locksmith does when you're locked out of your house is confirm you have the right to be there. That's not us being difficult — it protects you and your neighbors. A quick ID check or proof of residence lets us proceed with confidence, and it's standard practice for any legitimate home lockout service. Once that's settled, we assess the door: the type of cylinder, whether it's a standard door knob lock, a deadbolt, or a heavier mortise lock, and whether the door is bound in its frame from Texas humidity.

Our goal is always non-destructive entry. Most residential lockouts are resolved by manipulating the existing lock open with specialized tools — no drilling, no broken door, no splintered frame. In the rare case a lock is damaged, seized, or a high-security cylinder that can't be safely picked, we'll explain the situation, show you the options, and only drill as a last resort with your approval. If we do have to replace a cylinder, we can rekey or install a new one on the spot so you leave with a working, secure door.

Before we touch anything, you'll get a clear, itemized quote. What determines the number? The lock type and its condition, the time of day (overnight and holiday calls run differently than midday), how far we travel to reach you, and whether any parts or a new lock are needed. You approve the price first — then we work. If you're stuck right now, call (210) 512-4768; we answer 24/7 and dispatch the nearest mobile van.

New-Home Security Audit: Change These Locks Before Your First Night

Closing on a house in Helotes or signing a lease near Southtown is exciting — but you have no idea how many copies of your keys are floating around. Previous owners, their kids, realtors, contractors, cleaners, and pet-sitters may all have a working key. The single most important thing to do after you move in is a full lock rekeying so every old key stops working. Rekeying resets the pins inside your existing hardware to match a brand-new key, which is why so many people search 'how to rekey a lock' the week they move — it's faster and less wasteful than swapping every lockset.

During a new-home audit we walk the whole perimeter with you: front and back entries, the garage-to-house door (the most commonly overlooked point), side gates, and any detached casita or workshop. We check whether your deadbolts throw a full inch, whether strike plates are anchored into the framing rather than just the jamb, and whether older mortise lock bodies on character homes near Monte Vista are worn or sticking. We can key everything alike so one key runs the whole house, or keep zones separate if you rent out a room.

Not every door needs the same treatment. A rarely used side entry might just need a rekey, while a hollow builder-grade knob on your main door is worth upgrading. We'll tell you honestly where a simple lock change adds real security and where your existing hardware is perfectly good. Want us to come look before you unpack? Call (210) 512-4768 and we'll schedule a walkthrough that fits your day.

Lock Grades Explained: Which Doors Need a Deadbolt, a Knob, or a Mortise Lock

Locks are graded 1, 2, and 3 by durability and resistance to force. Grade 3 is the entry-level residential standard you'll find on many big-box door knob lock sets — fine for interior doors and low-risk applications, but not what you want as the only barrier on an exterior entry. Grade 2 offers a meaningful jump in cycle life and pick resistance and is a solid choice for most Bexar County front and back doors. Grade 1 is commercial-strength; it's overkill for a bedroom but ideal for high-traffic exterior doors, gates, and anywhere you want maximum resistance.

This is where the mortise lock earns its reputation. Unlike a bored cylindrical lock that fits into two round holes, a mortise lock installs into a deep pocket cut into the door edge, housing a robust lock body that combines a latch and deadbolt in one heavy assembly. You'll see mortise locks on older San Antonio homes, apartment building entries, and commercial storefronts because they handle constant use and resist force far better than a standard knob. We service, repair, and rekey mortise lock hardware, and we can retrofit modern security cylinders into vintage mortise bodies so you keep the original look with today's protection.

Matching the grade to the door is the whole game. We recommend Grade 1 or a quality mortise setup on primary exterior doors, a Grade 2 deadbolt paired with a keyed knob on secondary entries, and Grade 3 for interiors and closets. If your door has a mortise pocket already, replacing it with a cheap cylindrical lock actually weakens security and leaves gaps in the door — so we keep mortise doors as mortise doors and fit the right body for the job.

Smart Lock Installation and Ecosystems: Making Modern Tech Work on Real Texas Doors

Smart lock installation is one of our fastest-growing requests, and the biggest mistake homeowners make is buying hardware before checking compatibility. Not every smart lock fits every door. Deadbolt-style smart locks (keypad or app-controlled) drop into most standard bored doors, but a heavy entry with an existing mortise pocket needs a mortise smart lock — a purpose-built unit that fits the deep pocket and integrates a motorized deadbolt with a smart interface. We measure your door's backset, thickness, and bore before recommending anything, so you don't end up with a unit that won't mount or won't align with the strike.

Ecosystem matters as much as the lock itself. Some models talk to Wi-Fi directly, others need a hub, and many tie into Apple Home, Google Home, or Amazon Alexa for voice and remote control. Popular hardware from Schlage, Kwikset, and Yale each behave differently once they're on your network. We handle the full setup — mounting, calibration, connecting to your home network, creating admin and guest codes, and testing auto-lock and geofencing — and we show you how to add or delete codes yourself for a house-sitter or contractor.

A smart lock is only as strong as the mechanical hardware behind it, which is why we don't treat it as a gadget. We confirm the deadbolt fully engages, the strike is reinforced, and the batteries are accessible, and we keep a mechanical key override in place so a dead battery never becomes a lockout. Thinking about upgrading a front entry or converting a mortise door to a mortise smart lock? Call (210) 512-4768 and we'll confirm what fits before you buy.

Rekey vs. Full Lock Change: How to Know Which One You Actually Need

People often assume a security problem means buying new locks, but a rekey solves the majority of situations for less hardware and less waste. If your locks work smoothly, the finish and style are fine, and you simply want old keys to stop working — after a move, a breakup, a lost keyring, or a departed roommate — rekeying is the answer. To rekey a lock, our technician removes the cylinder, replaces the internal pins to match a fresh key, and reassembles it, so the same lock now opens only with the new key. It's quick, and we can rekey locks near you at your home the same day.

A full lock change makes more sense when the hardware itself is the problem. Rusted or grinding mechanisms, a deadbolt that no longer throws fully, a knob loose in the door, mismatched hardware you want to unify, or an upgrade from a flimsy Grade 3 knob to a Grade 1 deadbolt or mortise lock all call for replacement rather than rekeying. You also can't rekey your way from one manufacturer's key system to another — that requires new cylinders. And when you want smart features, a lock change is naturally part of the plan.

We'll always tell you which path serves you best rather than defaulting to the pricier one. Sometimes a single door needs replacement while the rest of the house just needs lock rekeying to match one key — a mixed approach that's common and completely practical. The final quote depends on how many cylinders are involved, whether we're supplying parts, the lock type, and travel to your location, and we confirm that number with you before starting.

Practical Ways to Harden Your Entry Points Without Overspending

Serious home security often comes from small, unglamorous fixes rather than expensive gadgets. Start with strike plates: swapping the short screws that come stock for three-inch screws that bite into the wall stud dramatically increases a door's resistance to a kick, and it costs almost nothing in parts. We do this as a matter of course when we're already at your door, and it's one of the highest-value upgrades for any entry with a standard door knob lock or deadbolt.

Next, look at the weak links most people ignore. The interior door between an attached garage and the house is frequently left with only a passage knob and no deadbolt, even though a garage is a common entry route. Sliding patio doors benefit from a secondary bar or pin lock, and older windows can be fitted with simple locks or sensors. For homes with worn mortise lock hardware on original doors — common in the older neighborhoods around Alamo Heights and Beacon Hill — a rebuild or fresh cylinder restores security without replacing a beautiful antique lock body.

Finally, plan against the lockout itself. A weatherproof lockbox with a code, a spare key left with a trusted neighbor, or a smart lock with backup codes means you're never fully stranded — much better than hiding a key under the mat, which is the first place anyone looks. If you'd like a straightforward walkthrough of where your home is vulnerable and what's worth doing, our team is happy to advise on-site. Call (210) 512-4768 — we answer 24/7 and we come to you anywhere in Bexar County.

“S.A. Locksmith & Security did a wonderful job coming out in a timely manner and getting my 2015 Porsche Macan S with same-day service got it done in less than 2 hours put everything back together like nothing ever happened. I'm very happy with the service and am definitely recommending them for anybody who has a Porsche. The dealership wanted over a thousand dollars they got it done for less than half excellent job!”

The dealership was going to charge me $600 & I would have to tow my truck over there. Kuddos and much thanks, was so happy to be on my way!”

“We got locked out of our house late last night. Called SA Locksmith & Security, and received a call from Andy within minutes. He was very professional and courteous. He headed to our location immediately with an arrival estimate. We were able to enter the premises prior to his arrival (he was only 4 minutes out). Andy was very understanding and thankful we were able to rectify our situation without further intervention. We will definitely use SA Locksmith & Security again if needed for any locksmith needs. Thank you Andy for being so friendly and understanding!!!”

Frequently asked questions

How much is a locksmith if I'm locked out of my house?

There's no single flat figure because a home lockout price depends on the lock type, the time of day, how far we travel to reach you, and whether any parts or a new cylinder are needed. An overnight or holiday call is priced differently than a midday one. We give you an exact up-front quote before any work starts, so you always approve the number first.

What do I do if I have locked myself out of my house?

Stay calm and check the obvious first: an unlocked back or side door, a garage keypad, a window that's cracked, or a spare key with a neighbor or in your lockbox. Don't try to force a door or break a window — that costs far more than a lockout call and can injure you. If you can't get in safely, call (210) 512-4768 and our mobile technician will reach you and use damage-free entry wherever possible.

Is there a 24-hour locksmith in Bexar County?

Yes. Bexar County Locksmith operates 24/7, including nights, weekends, and holidays, with mobile technicians dispatched across the county from central San Antonio out to Stone Oak, Helotes, Converse, and beyond. When you call (210) 512-4768 at any hour, a real person answers and sends the nearest available van to your location.

Who should I call if I'm locked out of my house with no key?

Call a trained, insured mobile locksmith rather than attempting a break-in. Our team specializes in residential lockouts and arrives with the tools to open standard knobs, deadbolts, and mortise locks without damaging your door in most cases. Reach us anytime at (210) 512-4768 and we'll verify you belong there, then get you back inside.

How much should a rekey cost, and what affects the price?

Rekeying is priced per cylinder, so the total depends on how many locks you want rekeyed, whether you want them all keyed alike, the lock type, and travel to your home. Rekeying is generally more economical than replacing hardware because it reuses your existing locks. We'll confirm the exact cost before we begin.

Can you rekey a lock, or do I need a full lock change?

If your locks work properly and you just want old keys deactivated, a rekey is usually all you need — we reset the internal pins to a new key. A full lock change is better when hardware is worn, damaged, being upgraded to a higher grade, or switched to a smart lock. We'll assess your doors and recommend the option that genuinely fits, not the most expensive one.

Do you install smart locks and mortise smart locks on older doors?

Yes. We handle smart lock installation on standard bored doors and can fit a mortise smart lock into doors with an existing mortise pocket, which is common on older San Antonio homes. We check backset, door thickness, and your smart-home ecosystem before recommending hardware, then mount, connect, and program it — always keeping a mechanical override so a dead battery never locks you out.

What areas of Bexar County do you serve?

We're mobile across the entire county, covering neighborhoods from King William, Monte Vista, and Alamo Heights to Alamo Ranch, Stone Oak, Converse, Helotes, and the surrounding communities. Because our technicians work from vans throughout the area, response times are fast wherever you are. Call (210) 512-4768 to confirm we're near you.
