We’re Strongbox Lock & Safe Co. of California, and we’ve been serving South San Francisco for over 42 years. The marine layer here is relentless. Salt-laden fog rolls off the bay, seeps into lock cylinders, and turns a five-year-old deadbolt into a stuck mess. We’ve replaced more corroded Schlage and Kwikset hardware on west-facing hillside homes than we can count. Our Lock Installation & Rekey team knows the difference between a standard rekey and the corrosion-damage rebuild these coastal conditions demand. Call (833) 294-4584 for a flat price before we roll.
Why Strongbox Lock & Safe Co. of California Is South San Francisco’s Preferred Lock Installation & Rekey Company
South San Francisco homeowners remember the last time a locksmith quoted $19 on the phone and handed them a $400 invoice. We don’t play that game. We quote a flat price before the truck leaves our shop, and that number matches the invoice.
Our reputation here is built on showing up. We recently rekeyed a mid-century tract home on Sunset Drive in the hillside neighborhood west of Highway 101, where the original 1960s knob lock had seized from salt-air corrosion inside the cylinder. We replaced it with a Schlage B60N deadbolt and rekeyed all exterior locks to a single key, adding a strike-plate reinforcement to accommodate the older door frame-a common fix for these 1940s-1960s homes.
Calls are answered by a live person, 24/7. No voicemail trees. Our background-checked, uniformed technicians present ID at every door. Every job carries our 90-Day Done Right Promise in writing. If it’s not right, we come back. No paperwork, no arguing.
We know the streets here. From the industrial pockets along Grand Avenue to the residential hills above El Camino Real, we don’t waste time getting lost or fishing for parts. Our trucks carry Medeco, Schlage, and Kwikset hardware so most jobs finish in one visit.
Our Lock Installation & Rekey Services in South San Francisco
Electronic Lock Installation
Electronic locks are increasingly popular in South San Francisco’s newer condo developments and renovated hillside homes. We install standalone electronic deadbolts and hardwired systems that integrate with existing door prep. For homes in the fog belt, we specify models with sealed keypads and corrosion-resistant contacts. A typical electronic lock installation in South San Francisco runs $280-$520, including hardware and programming. We stock Schlage and Kwikset electronic lines locally for fast turnaround.
Keyless Entry Systems
Keyless entry eliminates the key entirely. We install keypad, fob, and smartphone-enabled systems for South San Francisco homeowners who want to stop worrying about lost keys or tenant turnover. For rental properties in the high-turnover hillside neighborhoods, keyless entry saves a rekey fee every time a tenant moves out. Programming is included. We show you how to add and delete codes before we leave. Most residential keyless entry installations in South San Francisco cost $240-$480.
Biometric Lock Installation
Biometric locks use fingerprint recognition for entry. We install these for South San Francisco homeowners who want maximum control over access, particularly in multi-generational households or homes with caregivers. The technology has improved significantly. Modern biometric locks handle the moisture and temperature swings of the Peninsula fog belt better than earlier generations. We install and program units from trusted manufacturers, with backup key override for power failures. Expect $320-$580 for a quality biometric installation in South San Francisco.
Smart Lock Installation
Smart locks connect to your home’s WiFi or Z-Wave hub, allowing remote locking, guest codes, and activity logs. We install and configure these for South San Francisco homeowners who already use smart home platforms. The marine layer here can interfere with wireless signals in hillside homes with thick stucco walls, so we test connectivity during installation and recommend signal boosters when needed. Smart lock installation with full setup runs $260-$500 in South San Francisco.
Keypad Lock Installation
Keypad locks are the workhorse of keyless entry. We install mechanical and electronic keypads for South San Francisco homes, garages, and rental units. Mechanical models need no batteries and withstand salt-air exposure better than some electronic alternatives. For a duplex on Grand Avenue or a rental near Orange Memorial Park, a mechanical keypad means no service calls for dead batteries. Installation runs $180-$340.
Key Duplication
We cut keys on-site for South San Francisco customers, including high-security and restricted keyway blanks. For standard residential keys, duplication is quick and inexpensive. For Medeco, Schlage Everest, or other restricted systems, we verify authorization before cutting. Key duplication in South San Francisco starts at $4 for standard keys and runs $18-$45 for high-security blanks.

Trusted Brands We Service in South San Francisco
We install and service Schlage, Medeco, Kwikset, Mul-T-Lock, Abloy, Baldwin, Yale, and Sargent. Our South San Francisco warehouse stocks the hardware that fails most often in this climate: Schlage B60N deadbolts with corrosion-resistant finishes, Medeco high-security cylinders for restricted keyway applications, and Kwikset SmartKey rekeyable locks for rental properties. We don’t show up with whatever’s on the truck and hope it fits. We ask about your door, your existing hardware, and your security needs before we quote. That means one trip, one installation, one key that works.
Common Lock Installation & Rekey Problems We See in South San Francisco Homes
- Salt-laden fog seizes lock cylinders within a few years on west- and north-facing hillside homes. The marine layer penetrates standard lock housings, corroding pin tumblers and springs. We replace these with corrosion-resistant hardware and recommend annual lubrication with graphite or Teflon-based products, never oil-based lubricants that attract more moisture.
- Older door frames in mid-century tract homes lack proper shimming or strike-plate reinforcement. A modern deadbolt installed in a 1950s door frame without reinforcement will bind, misalign, and eventually fail to latch. We shim and reinforce as standard practice on these homes.
- In biotech campus complexes, mismanaged master key systems lead to unauthorized key duplication and compromised security. When tenants change in shared R&D parks, former employees sometimes retain keys. We rekey restricted keyway systems and rebuild master key hierarchies to restore control.
- High rental turnover in hillside neighborhoods creates rekey backlogs. Property managers sometimes wait too long between tenants. We offer scheduled rekey services and master key systems that let managers rekey individual units without replacing entire locksets.

FAQs - Lock Installation & Rekey in South San Francisco
Salt-laden fog accelerates corrosion inside lock cylinders and on exposed strike plates, particularly on west- and north-facing hillside homes. Pin tumblers seize, springs weaken, and keyways become sticky or jammed within three to five years instead of the fifteen to twenty years expected inland. We specify corrosion-resistant finishes and sealed hardware for South San Francisco installations, and we recommend annual inspection and proper lubrication. Call (833) 294-4584 to schedule a tune-up before your lock fails.
Yes. South San Francisco’s East-of-101 biotech corridor houses proprietary restricted keyway systems-Medeco, Schlage Everest, BEST SFIC-with master key hierarchies across multiple tenants in shared R&D parks. This complexity is unique on the Peninsula and requires specialized skills beyond typical residential work. We verify authorization, rekey cylinders, and rebuild master key systems to maintain security during tenant transitions. Call (833) 294-4584 for a confidential consultation.
A Grade 1 or Grade 2 deadbolt with strike-plate reinforcement, specifically the Schlage B60N or equivalent, installed with proper shimming for the older door frame. These homes were built with knob-lock-only prep and thin strike plates. A modern deadbolt without reinforcement will bind and fail. We match the hardware to the door, not the other way around. Call (833) 294-4584 for a free assessment of your specific door and frame condition.
Rekey between every tenant, and consider a master key system if you manage multiple units. The high rental turnover in South San Francisco’s hillside neighborhoods means keys change hands frequently. Former tenants, contractors, and cleaning services may retain copies. A master key system lets you rekey individual units without replacing entire locksets, saving money long-term. Call (833) 294-4584 to discuss master key options for your property.
Yes, with proper prep. Most smart locks require a standard 2-1/8 inch bore and 1-inch crossbore, which many 1940s-1960s South San Francisco doors lack. We modify door prep as needed, reinforce the frame, and test wireless connectivity in homes with thick stucco walls that can interfere with signals. The installation takes longer than on a modern door, but it’s entirely doable. Call (833) 294-4584 for a flat quote on your specific door.
