We’ve been driving to San Lorenzo since before the 580 connected it to the rest of the East Bay. The salt air off the Bay, the fog that rolls in thick through November, the identical wood-frame tracts between Hesperian Boulevard and Via Alamitos - we know how this place treats its locks. That matters when you’re standing outside a door that won’t open.
San Lorenzo sits unincorporated in Alameda County, which means Sheriff’s response rather than a city police department. The response window runs longer here than in incorporated neighbors. A proactive rekey or deadbolt upgrade isn’t paranoia; it’s arithmetic.
Why Strongbox Lock & Safe Co. of California Is San Lorenzo’s Preferred Lock Installation & Rekey Company
We’ve served communities around the Bay for over 42 years. San Lorenzo customers find us the same way most do - they were burned once by a $19-ad locksmith who quoted one price on the phone and invoiced another at the door. They don’t want the cheapest bid anymore. They want the job done once, done right, and never thought about again.
Our technicians are background-checked, uniformed, and present ID at every door. The price we quote on the phone is the price on the invoice. Every job carries our 90-Day Done Right Promise - backed in writing, no paperwork to file, no arguing. If it’s not right, we come back. That’s how we’ve stayed in business four decades.
Calls are answered by a live person, 24/7, including nights, weekends, and holidays. No voicemail trees. No callback queues. When you’re locked out on Grant Avenue at 11 PM, you talk to a human who dispatches a truck.
We know San Lorenzo’s streets - Hesperian, Washington, Lewelling - and we know the Bohannon tracts that define this community. That local knowledge saves time on every job.
Our Lock Installation & Rekey Services in San Lorenzo
Smart Lock Installation
Smart locks make sense for San Lorenzo homeowners who’ve finally had enough of fumbling for keys in the fog. We install Wi-Fi and Bluetooth-enabled deadbolts from Schlage and Yale that integrate with existing door prep when possible. On Bohannon-era tracts, we often need reinforcement plates - the original jambs are shallow, and smart lock housings are deeper than 1940s hardware. We stock the retrofit backplates so we don’t leave your door half-finished. Typical smart lock installation in San Lorenzo runs $280-$450 including hardware and labor.
Keyless Entry
Keyless entry systems - push-button, card-reader, or fob-activated - work well for San Lorenzo’s rental properties and multi-generational households. The same salt air that corrodes standard cylinders will eventually attack keypad contacts, so we specify marine-grade units when the door faces the Bay side. We’ve installed keyless entry on apartment conversions near Ashland Avenue and on single-family rentals throughout the 94580 zip. Most residential keyless installations fall between $220-$390.
Keypad Lock
Standalone keypad locks remain popular with San Lorenzo’s older homeowners who want simplicity without smartphone dependency. We favor mechanical keypad models from Kwikset and mechanical-electronic hybrids from Schlage for this market - fewer batteries to fail, no Wi-Fi to configure. The fog season means we always check door alignment before installing; a binding keypad will wear out its clutch mechanism in months. Budget $180-$320 for most residential keypad installations.
Biometric Lock
Biometric locks - fingerprint-activated deadbolts - are gaining traction in San Lorenzo’s updated tracts. The technology has matured; current models handle the moisture variation better than early generations. We still recommend a keyed override on every biometric install, because electronics and salt air are never fully reconciled. Installation runs $340-$520 depending on frame condition and whether we need to enlarge the strike pocket.
Key Duplication
Key duplication seems simple until you’re holding a worn Medeco or an original Kwikset from 1952 that no hardware store will touch. We duplicate keys on precision machines calibrated to factory spec, not the hand-held units that accumulate error. For San Lorenzo’s Bohannon tracts, we keep common vintage blanks in stock - the original builders used standardized keyways across hundreds of homes. Key duplication runs $8-$25 per key depending on blank type and complexity.

Trusted Brands We Service in San Lorenzo
We install and service Schlage, Kwikset, Medeco, and Yale - brands we’ve worked with long enough to know which models hold up to San Lorenzo’s climate and which don’t. We don’t push premium hardware where standard grade suffices, and we don’t install bargain cylinders that’ll corrode shut in three years of fog. Our trucks carry the common San Lorenzo retrofit inventory: backplates for shallow Bohannon jambs, stainless strikes for salt-air exposure, and the full range of modern ANSI hardware. Most parts are on the truck, which means most jobs finish in one trip.
Common Lock Installation & Rekey Problems We See in San Lorenzo Homes
- Salt-air corrosion seizes cylinders. The marine layer off San Francisco Bay carries enough salt to pit brass lock internals within a few years. We see this most on north- and west-facing doors. Stainless-steel strikes and corrosion-resistant cylinders add maybe $30 to a job and prevent the Sunday-night lockout.
- Winter fog swells original wood frames. Every November through February, we field calls about locks that suddenly won’t latch or keys that bind mid-turn. The wood expands, the strike plate no longer aligns, and the deadbolt throws into empty space. Often it’s a five-minute adjustment; sometimes we need to relocate the strike and fill the old screw holes.
- Garage-door hardware fails faster than inland. Springs, hinges, rollers, and opener chains corrode years ahead of schedule. We specify galvanized or coated springs, stainless fasteners, and nylon rollers on every San Lorenzo garage-door hardware replacement. The upfront cost is higher; the replacement cycle is longer.
- Original Bohannon locksets reach end of life. Seventy-year-old lock mechanisms weren’t designed for modern use patterns. We recently swapped out a seized deadbolt on a home on Via Alamitos, one of the original Bohannon tracts. The owner complained the key wouldn’t turn after weeks of foggy weather - classic salt-air corrosion. We installed a heavy-duty Schlage B660 deadbolt with a stainless-steel strike and reinforced the shallow jamb with a retrofit backplate, matching the standard prep pattern that lets us finish jobs in half the time.

FAQs - Lock Installation & Rekey in San Lorenzo
The late-autumn fog swells your original wood door frame, throwing the strike plate out of alignment with the deadbolt or latch. This happens reliably every November through February in San Lorenzo’s Bohannon tracts. We adjust or relocate the strike, and sometimes plane the jamb edge slightly. Call (833) 294-4584 before it gets worse - a binding lock eventually breaks its internal clutch.
Usually not without some reinforcement. The original door prep was sized for period hardware with shallower backsets and smaller face bores than modern ANSI standards. We stock retrofit backplates and strike boxes specifically for the Bohannon spec, so the modification is minimal - typically a reinforced strike pocket and a backplate to cover the original cutout. Most San Lorenzo Bohannon jobs take 45 minutes. Call (833) 294-4584 for a flat quote.
We recommend stainless-steel strikes and corrosion-resistant cylinders for any San Lorenzo door facing the Bay or getting direct fog exposure. Standard brass internals will function, but they’ll pit and bind faster here than in inland Castro Valley. The upgrade adds roughly $25-$40 per lock and typically doubles the service interval. Call (833) 294-4584 and we’ll spec it on the phone.
Yes, if you’re both in original Bohannon tracts with matching keyways - common in this planned suburb. We cut to the same bitting on our precision duplicator, or rekey both locks to a shared combination. We need proof you both own or control the properties. Shared keying runs $45-$75 per cylinder. Call (833) 294-4584 to arrange.
Immediately upon purchase, and again if any contractor, caregiver, or former tenant had key access. These tracts were built with standardized keying; it’s possible neighboring homes were keyed alike from the factory. We also recommend rekeying after any break-in attempt or lost key. The $45-$75 per cylinder is cheap compared to the alternative. Call (833) 294-4584 - we’ll schedule same-day in most cases.
