We’ve been serving South Houston for over 42 years, and we know this little city inside and out. Completely surrounded by Houston yet fiercely independent, South Houston sits in the industrial Ship Channel corridor where petrochemical workers on rotating shifts keep hours that don’t match the suburbs. That means lockouts at 11 PM. Rekey calls at 5 AM. We’ve answered them all. Our Lock Installation & Rekey team understands that when you’re coming off a graveyard shift at the refinery, a jammed deadbolt isn’t a tomorrow problem. Call (833) 695-3962 and a live person picks up, 24/7. No voicemail trees. No callback queues.

Our Lock Installation & Rekey Services in South Houston
Smart Lock Installation
Smart locks make sense for South Houston’s shift-working households. Coming home at 3 AM with arms full of gear? A Yale Assure Lock SL or Schlage Encode lets you walk in without fumbling for keys in the dark. We install and configure these systems to work with your phone, a keypad code, or both - whatever fits your routine. Our techs also know the local flood risk: we always check door frame alignment and weatherstripping before mounting any electronic components, because moisture intrusion from swollen frames is the fastest way to kill a smart lock in this zip code. Installation typically runs $180-$280 for a standard single-cylinder replacement, including setup and walkthrough.
Keyless Entry Systems
Keyless entry isn’t just for new construction. We’ve retrofitted keypads and card readers onto South Houston’s older brick-veneer homes and small commercial buildings alike. For families with teenagers or homes shared by multiple shift workers, keyless entry eliminates the key-hiding problem entirely. We stock Mul-T-Lock and Sargent keyless hardware with weather-resistant housings rated for the humidity that sits on this city like a blanket from April through October. Most residential keyless installations fall between $220-$380.
Keypad Lock Installation
Keypad locks bridge the gap between traditional hardware and full smart-home integration. Baldwin and Schlage keypad deadbolts are popular with South Houston homeowners who want code access without app dependency. These units hold up well against salt air if installed with proper door prep - something our techs verify on every call. A swollen frame will bind even the best keypad mechanism, so we plane, shim, or replace strikes as needed before the lock goes in. Standard keypad installation: $160-$260.
Biometric Lock Installation
Biometric locks - fingerprint readers - are gaining traction with South Houston homeowners who want maximum access control. We install fingerprint-enabled deadbolts from select premium manufacturers, always checking that the door frame and jamb are square first. These units are particularly sensitive to frame shift, and South Houston’s postwar homes have had 60-plus years to settle. Where the frame is out of plumb, we correct it before mounting. Biometric installation starts around $280-$420 depending on hardware grade and door prep required.
Key Duplication
We cut keys on-site for Schlage, Kwikset, Yale, Medeco, Mul-T-Lock, and most other residential and commercial keyways. For South Houston’s older homes with worn or unusual keyways, we can often source blanks that big-box stores don’t stock. Key duplication runs $4-$12 per key for standard residential, $15-$35 for high-security blanks. We can rekey your existing locks to match a new master key system while we’re there - often the most cost-effective security upgrade for homes with mismatched hardware.
Electronic Lock Repair and Replacement
Electronic locks that have succumbed to humidity, power surge, or flood damage are a common call in South Houston. We diagnose the failure, determine whether repair or replacement makes sense, and quote both options upfront. If moisture has compromised the circuit board, replacement is usually the wiser spend. We carry weather-hardened replacements in the truck for faster turnaround.

Trusted Brands We Service in South Houston
We install and service the full range of premium security hardware: Schlage, Medeco, Mul-T-Lock, Abloy, Baldwin, Yale, Kwikset, and Sargent. For South Houston customers, this means we don’t show up with whatever’s on sale this month. We stock the right strike plates for settled frames, the right corrosion-resistant finishes for humid air, and the right keyway systems for your security level. Most parts are carried in our service vehicles, so we’re not making a supply run while your door sits unsecured. Need a specific Baldwin finish to match existing hardware? We can source it, usually within 48 hours.
Common Lock Installation & Rekey Problems We See in South Houston Homes
- Deadbolts jam after rainstorms. South Houston’s pine door frames swell in high humidity and after flooding, binding the bolt against the strike plate. We plane the frame, install an adjustable strike, and test throw depth before we leave. The lock isn’t broken - the frame has moved.
- Salt-air corrosion attacks garage hardware. Proximity to the Ship Channel means salt-laden air accelerates rust on garage-door springs, opener chains, and track fasteners. Galvanized or coated springs and stainless-steel hardware last years longer here. We replace with corrosion-resistant components and inspect annually.
- Postwar door frames have settled out of square. Homes built in the 1950s and 1960s have had decades to shift. Deadbolts that once threw smoothly now scrape, stick, or fail to engage fully. We correct frame alignment, upgrade to longer screws that bite into structural framing, and install strikes that compensate for the gap.
- Flood damage warps tracks and shorts electronic components. After Harris County storm events, we find garage tracks bent by water pressure and keypad locks on security doors fried by moisture intrusion. We replace with stainless hardware and recommend elevated mounting for electronic units in flood-prone properties.

FAQs - Lock Installation & Rekey in South Houston
Humidity and floodwater swell the pine door frames common in South Houston’s postwar housing stock, compressing the gap between bolt and strike plate. The lock cylinder is usually fine - the frame has shifted. We plane or shim the frame, install an adjustable strike, and verify full bolt throw. Call (833) 695-3962 and we’ll diagnose it properly instead of drilling out a good lock.
In South Houston’s salt-air environment near the Ship Channel, standard garage-door springs corrode and fail in 2-3 years versus 7-10 years inland. We install galvanized or coated springs that last longer, and we inspect the full hardware set - rollers, hinges, track fasteners - for rust during every call. Annual inspection catches corrosion before it snaps a spring at the worst moment.
Yes. We’ve rekeyed original 1950s and 1960s hardware throughout South Houston’s neighborhoods without damaging antique cylinders or mismatched keyways. After a May 2024 downpour, we unlocked a ’53 bungalow on Nebraska Ave where the deadbolt wouldn’t throw. The pine frame had swollen 3/16″ - we planed it, installed a new Schlage B560 deadbolt with a nylon strike plate, and rekeyed all three exterior doors to match. Older homes need patience and the right tools, not force.
Absolutely. Smart locks with keypad or phone entry are ideal for South Houston’s rotating-shift workforce in the petrochemical industry. No key to fumble in the dark. No waking family members. We configure codes, set auto-lock timing, and walk you through operation before we leave. Installation takes about an hour, and we test everything in real-world conditions - including wet hands, which matter here.
Very common. Salt air from the Ship Channel accelerates corrosion on opener chains, springs, and hardware throughout South Houston. We see rusted chains fail prematurely and take openers with them. We replace with stainless-steel or coated components rated for coastal exposure, and we can convert to belt-drive openers that eliminate the chain entirely. If you’re seeing orange rust, call before it breaks - (833) 695-3962 for a free inspection quote.
