Daniel Novak founded Novak Lock & Security in 2002 on one rule: the price quoted on the phone is the price on the invoice. Haven Standard Clause 1. That applies to every emergency call in San Antonio, whether it’s a 2 a.m. lockout or a broken key in a gate padlock. You get a written price before we send anyone, and the technician is not permitted to change it when he arrives.
Why Novak Lock & Security Is San Antonio’s Preferred Emergency Locksmith Company
San Antonio is not a generic market. The Joint Base San Antonio footprint, Lackland AFB, Fort Sam Houston, Randolph AFB, means our dispatchers block out heavy rekeying schedules from May through August, when PCS season floods Westover Hills, Converse, and Universal City with incoming military families. “We just got orders and moved in, we need all the locks changed today” is the standard opening line from March through Labor Day. We staff for it.
On the residential side, San Antonio’s older housing stock presents a different set of problems. King William and Monte Vista homes date back to the late 1800s and early 1900s, many still carrying original mortise-lock hardware. Northside and westside ranch tracts from the 1970s through the 1990s went in with builder-grade cylindrical locksets that are now decades past their service life. Stone Oak and Helotes brought newer construction, much of it smart-lock-ready, but with inconsistent door preparation. Our techs know the difference between a 1950s mortise cylinder and a Kwikset SmartKey, because they see both every week.
Every emergency call in San Antonio gets a background-checked, uniformed technician who leaves a documented photo record at job completion. That’s not a promise. It’s a procedure, written into The Haven Standard, the same quality framework we’ve applied across more than 60,000 locks, keys, and systems since 2002.
Our Emergency Locksmith Services in San Antonio

24/7 Emergency Lockout
House lockout response in San Antonio depends on where you are. Alamo Heights, Terrell Hills, and Monte Vista are 20 to 30 minutes from our dispatch desk. Westover Hills and Converse are 25 to 40. Helotes and Schertz run 35 to 50 depending on traffic on Loop 1604. We tell you the window when you call, and the dispatcher quotes the price right then. Non-destructive entry is our default. We pick first, drill only when there’s no other option, and we tell you before we reach for the drill.

Broken Key Extraction
Broken keys happen in San Antonio more than most cities, and there’s a reason. The same expansive Blackland Prairie clay that shifts foundations also puts stress on deadbolts and knobs. When a lock binds, people force the key, and keys snap. We extract broken keys from Kwikset, Schlage repair in San Antonio, Medeco, Mul-T-Lock, and Baldwin cylinders, then cut a replacement on the spot from the code we decode or read directly from the remaining key fragment.

Safe Opening
San Antonio houses a lot of safes, gun safes in particular. The military population and the large number of acreage properties means many homes have at least one safe, often bolted in a closet or garage. When the lock fails or a combination is lost, we open safes using the least invasive method that’s appropriate, decoding where possible before drilling. We also repair and re-code electronic safe locks, including most residential gun-safe brands.

Eviction Lock Change
For landlords and property managers in San Antonio, eviction lock changes are a scheduled, documented job. We do them on the same written-price model: the dispatcher quotes a flat rate per cylinder, the tech arrives on time, changes the locks, and leaves you a photo record of every cylinder swapped. You also get the written invoice before anyone leaves the property. That documentation matters if the tenant challenges the lock change later. We serve landlords from Converse to Schertz to the far west side, including commercial properties.

Trusted Brands We Service in San Antonio
We’re factory-authorized for Medeco and Mul-T-Lock high-security work, and we service Baldwin, Schlage, Kwikset, Yale, and Sargent hardware daily. That matters in an emergency: if you have a Medeco deadbolt and someone tries to pick it, they’ll likely fail and reach for a drill. We carry key decoders for Medeco and Mul-T-Lock so we can generate a new key from the cylinder itself, non-destructively. Our San Antonio vans stock common residential parts from all these brands, plus vintage cylinder pins for the older mortise locks in King William and Monte Vista. We’re also the city’s Emergency Locksmith team that doesn’t tell you the part has to be ordered when it’s a Kwikset or Schlage cylinder that every supply house in the city keeps in stock.
Common Emergency Locksmith Problems We See in San Antonio Homes

- Deadbolts binding after a dry spell. San Antonio’s clay soil shrinks during drought, foundations move, door frames shift out of square, and deadbolts won’t throw. We see a spike in these calls every time a prolonged dry stretch breaks with heavy rain. The repair is usually strike-plate realignment and a minor hinge adjustment, not a new lock.
- Original mortise locks jammed in King William and Monte Vista. These are 100-year-old locks with hand-cut keys. If a tech drills one out because he doesn’t stock vintage pins, the door and hardware are often destroyed. We carry the pins and can usually rebuild the mortise body in place.
- Acreage lockouts where nobody thought about the outbuildings. The front door gets rekeyed, the detached workshop, horse barn, and gate stay on the old key. For rural and acreage properties around San Antonio, everything should go on one key in one visit. We plan for that from the first call.
- High-security deadbolts that get drilled because the tech can’t decode them. Medeco and Mul-T-Lock cylinders don’t pick easily. We carry decoders for both, which means non-destructive entry on high-security hardware in San Antonio is possible in most cases.

FAQs - Emergency Locksmith in San Antonio

Yes. We carry enough cylinders and key blanks on the van to rekey seven to ten locks in a single visit, including outbuildings, gates, and padlocks. Tell the dispatcher the full count when you call so the tech brings the right keying kit. A full acreage rekey, house plus two outbuildings plus a gate, typically runs $140 to $220 in San Antonio depending on hardware type. Call (331) 310-8471 for an exact written quote before we dispatch.
Yes, it does. San Antonio sits on expansive Blackland Prairie clay and caliche. When it dries out, the soil contracts, the foundation shifts slightly, and door frames move out of square. The deadbolt no longer lines up with the strike plate, and the bolt won’t throw. In our experience across the city’s older neighborhoods, the fix is usually strike-plate realignment and minor hinge adjustment, not a new deadbolt. But every house is different, and the tech will see exactly what’s happening and quote the fix in writing before any work is done.
For Fort Sam Houston, Converse, and Universal City during PCS season, we typically arrive within 30 to 45 minutes of your call, and a standard rekey of three to five cylinders takes about an hour on site. If you need it done before you leave for TDY the same day, tell the dispatcher and we’ll make sure the schedule fits. The price gets set in writing on the phone before anyone is dispatched.
In most cases, yes. Many smart locks, including Schlage Encode, Yale Assure, and Kwikset Halo, have a mechanical key override or can be opened non-destructively by bypassing the electronic component. We attempt non-destructive entry first on every call in San Antonio, and we only drill if the lock is failed beyond repair or if there is no alternative. If drilling is the only option, we stop and tell you before doing it, and we quote the replacement hardware in writing first.
We can, but we often don’t need to. Our techs carry vintage cylinder pins for the original mortise locks common in Monte Vista and King William. In many cases we can disassemble, clean, rebuild, and rekey the original mortise body in place, preserving the door and hardware. That typically runs $120 to $220. If you’d rather replace it with a modern deadbolt, we’ll quote the new hardware and installation as a separate written option, and you choose. The quote is on the phone before we arrive, and it doesn’t change at the door.
