We’ve been serving Lomita and the South Bay for over 42 years. Our technicians know the difference between a routine rekey on a standard bore and the stacked-over nightmare a previous tenant left behind on a Western Avenue duplex. We carry Schlage, Kwikset, Medeco, and Yale hardware on every truck, so we’re not making a second trip while your door sits unsecured.
Why Strongbox Lock & Safe Co. Is Lomita’s Preferred Lock Installation & Rekey Company
Lomita’s roughly 1.9 square miles of post-WWII tract homes present lock problems you won’t find in newer construction. Original door preps from the 1950s and 1960s often lack the backset and cross-bore clearance for modern deadbolts. Our Lock Installation & Rekey crew has bored, reinforced, and upgraded hundreds of these older doors across the 90717 ZIP code.
We arrive when we say we will. From our Los Angeles base, Lomita calls get same-day or next-morning scheduling, with emergency lockout response typically under 45 minutes during daylight hours. Every technician is background-checked, uniformed, and presents ID at your door - because the person who opens your locks should be the most verifiable person you’ve ever hired.
Our 90-Day Done Right Promise covers every job in writing. Not right? We come back. No paperwork to file, no argument. That promise has kept us in business across South Bay communities for four decades, and we intend to be here when your grandchildren need a locksmith.
Our Lock Installation & Rekey Services in Lomita
Smart Lock Installation
Smart locks on Lomita’s older homes require honest assessment. That 1950s door with original Kwikset hardware? The prep probably won’t accept a modern smart deadbolt without new bore work. We measure first, quote the full job - door prep, hardware, and installation - so you’re not surprised mid-project. We install Wi-Fi and Z-Wave models from Schlage and Yale with weather sealing rated for the marine-layer humidity that hits north- and west-facing entries hardest.
Keyless Entry
Keyless entry systems eliminate the key entirely - a practical upgrade for Lomita rental properties with frequent tenant turnover. No more rekeying every six months. We install keypad and RFID systems that stand up to salt air, with override keys for lockout protection. For properties along Western Avenue with non-standard bores, we rebuild the door prep to factory spec before mounting hardware. Done right, and backed in writing.
Keypad Lock
Standalone keypad locks bridge old and new. They’re mechanical or electronic, require no smartphone, and suit Lomita homeowners who want convenience without complexity. We favor Schlage and Yale keypad models with corrosion-resistant internals for coastal-adjacent homes. On original doors with 1⅜-inch bore holes, we often need to open to 2⅛ inches and add a reinforcement plate - work we quote upfront, never after arrival.
Biometric Lock
Biometric locks - fingerprint readers - are increasingly requested by Lomita homeowners upgrading security. The technology has matured, but the hardware is unforgiving of sloppy prep. We install fingerprint-enabled deadbolts with stainless steel internals rated for humid environments, and we warranty the electronics under our 90-Day Done Right Promise. Not every old door accepts biometric hardware cleanly; we’ll tell you straight if yours needs more than a swap.
Key Duplication
Key duplication in Lomita isn’t just about cutting a blank. Corroded original keys from seized locks often copy poorly. We clean, measure, and cut on precision equipment, and we can decode worn Medeco or Schlage keys when the original is too damaged to trace. For properties with multiple lock generations - common in rentals with stacked-over installs - we match the new key to the working cylinder, not the worn original.
Electronic Lock
Electronic locks with motorized bolts suit commercial properties and some residential applications in Lomita. We install and service hardwired and battery-powered units, with attention to weatherproofing for exterior mounting. The marine layer here kills cheap electronics fast. We specify hardware with IP ratings that account for actual South Bay conditions, not just laboratory testing.

Trusted Brands We Service in Lomita
We stock and install Schlage, Kwikset, Medeco, and Yale - brands we’ve worked with for decades and can service without ordering parts. For Lomita’s salt-air environment, we specify corrosion-resistant grades when available: stainless steel pins, sealed cylinders, and marine-rated finishes. Our trucks carry common Lomita replacement hardware, so a seized deadbolt on a Narbonne Avenue home doesn’t wait for a warehouse run. Fast turnaround matters when your front door won’t lock.
Common Lock Installation & Rekey Problems We See in Lomita Homes
- Corroded cylinders from marine-layer salt air. The persistent South Bay fog that rolls through Lomita most mornings from late spring to early fall keeps exterior hardware damp. North- and west-facing entries that never fully dry suffer seized pins and stiff key turns within 3-5 years of installation. We extract frozen cylinders and specify marine-grade replacements.
- Stacked-over lock installs in rental properties. Along Western Avenue and surrounding streets, previous tenants often added their own deadbolts off-center from original preps. The result: two bore holes, none standard, with a thin web of door material between them. A rekey call becomes a full door-prep and hardware replacement. We quote this honestly when we see it.
- Obsolete post-WWII door preps. Lomita’s tract homes from the late 1940s through early 1970s frequently carry 1⅜-inch or 1½-inch bore holes with shallow backsets. Modern deadbolts need 2⅛ inches and a standard 2¾-inch or 2⅜-inch backset. We bore to spec, add reinforcement plates, and ensure the new hardware seats solidly.
- Detached garage side-entry failures. Aging side doors on Lomita’s detached garages often carry obsolete lock prep and hardware no longer manufactured. Rather than cobbling repairs, we typically recommend new bore work and modern deadbolts - quoted flat, installed same visit.

FAQs - Lock Installation & Rekey in Lomita
Salt-laden marine-layer air from San Pedro Bay corrodes lock cylinders, pins, and springs faster than in drier inland cities. North- and west-facing doors that don’t get morning sun-drying are especially vulnerable. We specify marine-grade hardware with stainless steel internals and sealed cylinders for Lomita’s coastal-adjacent conditions. Call (877) 664-8139 to discuss corrosion-resistant upgrades - estimates are free.
Rekey if the hardware is standard, functional, and less than 10 years old. Replace if you find stacked-over bores from previous tenants, corrosion damage, or obsolete prep that won’t accept modern keyed-alike systems. Many Western Avenue rentals need more than a simple rekey. We’ll assess and quote both options honestly on the phone. Call (877) 664-8139 for a free second opinion on any written estimate you’ve already received.
Often yes, but usually not without door prep work. Original 1950s bore holes are typically 1⅜ inches - smart deadbolts need 2⅛ inches with standard backset. We measure, quote the full job including prep, and install weather-sealed smart locks rated for humid environments. Call (877) 664-8139 to schedule an assessment - we’ll tell you straight what your door needs.
A Grade 1 or Grade 2 deadbolt with stainless steel or brass internals and a marine-rated finish. We typically recommend Schlage B60N or Medeco Maxum for Lomita’s salt-air exposure, installed with proper door reinforcement. Cheap hardware corrodes and seizes within a few years here. Call (877) 664-8139 to discuss the right hardware for your exposure - estimates are free.
Previous tenants installed their own deadbolts off-center from the original prep rather than rekeying existing hardware. This “stacked-over” install is common in Lomita’s small rental properties, especially along Western Avenue. The result is a non-standard door that won’t accept a clean rekey and needs full prep rebuild. We encounter this regularly and quote the correction upfront. Call (877) 664-8139 for an exact assessment.
