Why Strongbox Lock & Safe Co. Is Martinez’s Preferred Lock Installation & Rekey Company
We’ve been serving Contra Costa County for over 42 years, and Martinez has always been central to our route. Gil Navarro built this company on the principle that the person who opens your locks should be the most verifiable person you’ve ever hired - background-checked, uniformed, ID at the door, every single time.
Martinez customers tell us the same story: they called a $19-ad locksmith once, watched the price triple when the truck arrived, and swore never again. Our answer is simple - we quote a flat price on the phone, put it in writing, and that’s the number on the invoice. No bait, no switch, no haggling over labor hours.
Our response time to Martinez averages under 40 minutes during business hours and under an hour for overnight emergency calls. We know the difference between the tight parking on downtown Plaza streets and the steep driveways climbing toward Briones Regional Park, and we arrive prepared for both.
Every job carries our 90-Day Done Right Promise - backed in writing, no paperwork, no arguing. If it’s not right, we come back. We’ve honored that promise in Martinez for decades, and we plan to be here in thirty more years.
Our Lock Installation & Rekey Services in Martinez
Smart Lock Installation
Smart lock installation in Martinez homes runs $180-$320 for most residential doors, including Wi-Fi bridge setup and smartphone app pairing. We install Schlage Encode, Yale Assure, and Kwikset Halo models that withstand the salt-laden fog rolling off the Carquinez Strait - a specification we pay attention to because we’ve replaced too many budget electronic locks that corroded within eighteen months on waterfront properties. For homeowners in the older neighborhoods near downtown, we select retrofit smart deadbolts that mount cleanly without drilling new holes through century-old doors.
Keyless Entry Systems
Keyless entry installation for Martinez residential and commercial clients typically costs $220-$450 depending on credential type - keypad, card reader, or fob system. The Shell Martinez Refinery and the industrial corridor along the waterfront generate regular demand for restricted-keyway keyless systems that audit who enters and when, a specialization that bedroom communities like Pleasant Hill simply don’t require. We program master-key hierarchies and schedule-based access for facilities that need them, and we service what we install - no subcontractor networks, no disappearing acts.
Keypad Lock Installation
Keypad lock installation in Martinez ranges from $150-$280 for mechanical models and $200-$380 for electronic versions with backlighting and temporary code features. We recommend mechanical keypads for exterior gates and outbuildings exposed to direct salt spray - no batteries to fail, no circuit boards to corrode. For the Victorian and Craftsman homes clustered around Escobar Street and Berrellesa Street, we carry keypad deadbolts in oil-rubbed bronze and aged nickel finishes that don’t look out of place on a hundred-year-old door.
Biometric Lock Installation
Biometric lock installation in Martinez starts at $280 for residential fingerprint deadbolts and extends to $600+ for commercial multi-user systems. The technology has improved - today’s sensors read through minor moisture and temperature variation, which matters on mornings when the marine layer sits thick over downtown. We don’t oversell biometrics for every application; for a single-family home in the Hidden Lakes area, a quality keypad may serve you better. We tell you that upfront because our price is flat and our reputation here is long.
Key Duplication
Key duplication in Martinez costs $4-$18 per key depending on blank type, with high-security Medeco and Mul-T-Lock blanks at the upper end. We cut keys on precision duplicators calibrated weekly, and we stock blanks for the restricted keyways used by many Martinez commercial clients and some older residential buildings. If you’ve got a skeleton key for an original mortise lock, we may refer you to a specialty shop - we won’t pretend we can duplicate what we can’t, and we won’t waste your time.

Trusted Brands We Service in Martinez
We install and service Schlage, Kwikset, Medeco, and Yale hardware from stock we carry on every Martinez service vehicle - not “we’ll order it and come back next week.” That matters when your deadbolt seized this morning and you need to lock up before the fog rolls in tonight. For the historic mortise locks common in Martinez’s pre-WWII housing, we source period-appropriate replacement parts through specialty suppliers we’ve cultivated relationships with over decades. We don’t slap a modern cylinder into an antique lockset and call it good. The right lock goes on the right door.
Common Lock Installation & Rekey Problems We See in Martinez Homes
- Salt-fog corrosion seizes exterior cylinders within 1-2 years. Sitting directly on the Carquinez Strait, Martinez catches marine fog that oxidizes deadbolts, padlocks, and gate latches measurably faster than in Concord or Walnut Creek just inland. We see this constantly on waterfront properties along Marina Vista Avenue and the Shell refinery access roads - cylinders that turn fine in dry October and freeze solid by February.
- Wooden door frames expand and contract seasonally, binding mortise locks. The daily temperature swing between cool damp mornings and warm afternoons shifts Victorian and Craftsman door frames enough to misalign latches and stress cast-iron lock bodies. We adjust strike plates, deepen mortise pockets, and sometimes plane door edges to restore smooth function without destroying original hardware.
- Homeowners damage skeleton-key mortise locks with modern rekeying tools. Original mortise locksets from the 1890s-1930s require specialized disassembly knowledge and period-specific parts. We’ve replaced too many cracked cast-iron frames where someone forced a modern pin-tumbler rekeying approach onto mechanism never designed for it. On Marina Vista Avenue, we rekeyed a 1904 Victorian’s original Sargent mortise lock where the cylinder had seized from salt fog. We disassembled the 120-year-old mechanism, sourced a period-correct replacement cam, and installed a new Schlage deadbolt on the back door, all while preserving the original hardware’s historic look.
- Smart locks fail prematurely from moisture intrusion. Budget electronic locks installed without weatherproofing specifications corrode quickly in Martinez’s coastal environment. We specify IP-rated hardware for exterior applications and verify gasket integrity during installation - details that add nothing to our price but years to the product’s life.

FAQs - Lock Installation & Rekey in Martinez
Exterior locks in Martinez need lubrication and inspection every 12-18 months due to salt-fog corrosion, and deadbolts on waterfront properties may need attention annually. We use graphite-based lubricants that don’t attract grit, and we inspect for cylinder pitting and bolt corrosion before it causes a lockout. Our $89 Seasonal Tune-Up covers full exterior lock service - call (877) 664-8139 to schedule before the heavy fog season.
Yes - original mortise lock repair and rekeying is a specialty we’ve developed over decades serving Martinez’s Victorian and Craftsman housing stock. These locks require disassembly skills and parts sourcing that standard pin-tumbler technicians simply don’t possess. We carry replacement cams, springs, and skeleton-key blanks for common period manufacturers, and we’ll tell you honestly when a lock is beyond salvage.
Yes - we select retrofit smart deadbolts that install through the existing 2-1/8″ bore without new drilling, and we stock finishes in oil-rubbed bronze and aged nickel that complement period hardware. The Schlage Encode Plus and Yale Assure SL 2 both offer slim profiles that don’t dominate a historic door visually. We preserve your original mortise lock on the same door when possible, giving you modern convenience without sacrificing character.
Yes, seasonal binding is common in Martinez’s older wooden doors due to the daily temperature swing between cool damp mornings and warm afternoons, combined with marine moisture absorption. The wood expands and contracts, shifting the door within its frame and stressing the lock mechanism. We adjust strike plates, deepen mortise pockets, and sometimes plane the door edge slightly to restore smooth latching year-round - not normal, but fixable.
Yes - we design and install master-key systems with restricted keyways for the Shell refinery corridor and other industrial facilities along the Carquinez waterfront. These systems prevent unauthorized key duplication and provide audit-trail capability for hazardous facilities that require it. We work with Medeco, Mul-T-Lock, and Schlage Primus keyways, and we maintain key control documentation in compliance with facility security protocols. Call (877) 664-8139 for a site assessment and written estimate.
