Fast, Reliable Lock Installation & Rekey Across Fairfax
Lock installation and rekeying in Fairfax typically runs $140-$380 depending on hardware grade, and our technicians can usually be on site within 35-55 minutes for standard calls. We answer live, 24/7, at (833) 294-4584.
We’ve been serving Fairfax homeowners for decades, and we know the terrain. The town’s inland valley position traps moisture from the coast, and that dampness finds every exterior lock on these old bungalows. Our Lock Installation & Rekey team carries marine-grade hardware and the patience to deal with swollen jambs and seized cylinders that flatland locksmiths rarely encounter. Whether you’re in the flats near downtown or up the winding lanes off Bolinas Road, we plan the route and bring the right stock.
Why Strongbox Lock & Safe Co. of California Is Fairfax’s Preferred Lock Installation & Rekey Company
Fairfax residents know the difference between a locksmith who quotes $19 on the phone and one who quotes the real price before the truck rolls. We’ve built our reputation in Marin County over 42 years by being the latter. Our technicians are background-checked, uniformed, and present company ID at every door - no exceptions.
Homeowners in Fairfax’s 94930 and 94978 ZIP codes call us back because the job gets done right. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument, no charge. That’s how we’ve stayed in business since before most of these bungalows got their second owners.
Response time to Fairfax averages 35-55 minutes from dispatch, though calls to the narrow hillside lanes off Bolinas Road or upper Cascade Drive sometimes take longer - those one-lane roads with no turnaround require a smaller service vehicle and a driver who knows the backup routes. We plan for this. A dispatcher in San Rafael’s flat grid never has to think about it.
Gil Sanderson has led Strongbox Lock & Safe Co. since its early days, and the company’s K.E.Y.S. values - Krafted right, Every time, Your home first, Standing behind it - still govern how we handle every lock in Fairfax.
Our Lock Installation & Rekey Services in Fairfax
Smart Lock Installation
Smart locks make sense for Fairfax homeowners who want keyless entry without replacing a perfectly good door. We install Schlage Encode, Yale Assure, and Kwikset Halo units that integrate with existing deadbolt prep - critical on these 1920s-1940s Craftsman doors where the jamb spacing isn’t always standard. The damp valley air here eats battery contacts, so we spec units with sealed compartments and use dielectric grease on terminals. A typical smart lock installation in Fairfax runs $220-$340 including hardware and labor. We program everything, show you the app, and leave a physical key override - because when the fog rolls thick and your phone’s wet, you’ll want that backup.
Keyless Entry Systems
Keyless entry covers everything from push-button deadbolts to full electronic strikes for side gates and garage entries. Fairfax’s hillside homes often have multiple access points - main door, garden gate, detached studio - and carrying three keys gets old fast. We key alike where possible and install standalone keypads where wiring a full system isn’t practical. The marine-grade keypads we spec for Fairfax resist the corrosion that kills cheaper units in two winters. Most keyless entry jobs here fall between $180-$320. We quote flat on the phone before we drive.
Keypad Lock Installation
Keypad locks suit Fairfax’s rental cottages and accessory dwelling units, where tenants change but the hardware should last. We see a lot of these in the downtown-adjacent flats and along the older streets near Peri Park. Our keypad installs use Medeco or Schlage commercial-grade cylinders with override keys, and we set master codes that owners keep while tenants get temporary codes. The price quoted is the price paid - typically $190-$290 installed. No trip charges, no hardware markups we don’t disclose upfront.
Biometric Lock Installation
Biometric locks - fingerprint readers - are increasingly popular with Fairfax homeowners who’ve had enough of lost keys and want something that works even when hands are cold and damp from Marin weather. We install units that store multiple fingerprints, work with wet fingers, and include mechanical key overrides. These require precise door prep on old Craftsman frames, and we measure twice before cutting. Biometric installation in Fairfax generally runs $280-$420. We warranty the electronics and the install under our 90-Day Done Right Promise.
Electronic Lock Repair & Rekeying
Not every electronic lock needs replacing. We repair and rekey existing electronic deadbolts when the motor, clutch, or wiring has failed but the housing is sound. Fairfax’s moisture problem shows up here too - corroded battery terminals, swollen circuit board housings, seized solenoids. We stock replacement motors and can often rebuild what a less experienced tech would swap entirely. Diagnostic and repair runs $140-$240; rekeying an electronic cylinder starts at $120.
Key Duplication
We cut keys by code or by sample, including restricted keyways like Medeco and Mul-T-Lock that hardware stores can’t duplicate. For Fairfax’s older homes with original or first-generation hardware, we often need to decode worn keys or disassemble the lock to determine the pinning. Key duplication runs $8-$35 depending on blank type and complexity. We test every key in the lock before you pay.

Trusted Brands We Service in Fairfax
We install and service Schlage, Medeco, Kwikset, and the full line of premium security hardware - Mul-T-Lock, Abloy, Baldwin, Yale, and Sargent. For Fairfax’s coastal moisture environment, we stock marine-grade and stainless-steel options that standard distributors don’t carry. Our van carries Schlage B60N deadbolts with stainless bolts, Medeco Maxum cylinders with proprietary plating, and Kwikset SmartKey units with upgraded internal components. When a Fairfax call comes in for a seized cylinder, we don’t have to drive back to the warehouse - we have what fits, and we have the corrosion-resistant upgrade that prevents the next failure.
Common Lock Installation & Rekey Problems We See in Fairfax Homes
- Seized exterior deadbolts from valley moisture. Fairfax’s position in this inland valley traps coastal fog and yields measurably higher annual rainfall than San Anselmo or Novato. Exterior lock cylinders on pre-war bungalows corrode and seize solid, often requiring extraction rather than simple rekeying. We replace with marine-grade hardware and treat internals with Corrosion-X.
- Misaligned deadbolts from swollen wood frames. The sustained dampness softens hillside foundations and causes seasonal swelling in aging wood jambs. A deadbolt that worked in September won’t latch in January. We plane, shim, or replace strike plates and sometimes relocate the entire bore to match the door’s settled position.
- Obsolete keyways in original hardware. Many Fairfax Craftsman cottages still carry first-generation locksets with keyways no longer manufactured. Rekeying isn’t possible - we retrofit modern cylinders into vintage housings or replace with period-appropriate reproductions that accept current key systems.
- Access delays on narrow hillside lanes. Lockout calls to residences above downtown, particularly off Bolinas Road or upper Cascade Drive, require smaller vehicles and experienced drivers. Response takes longer, but we arrive equipped rather than turning around to fetch forgotten gear.

FAQs - Lock Installation & Rekey in Fairfax
Yes. Fairfax’s inland valley traps coastal fog and records higher annual rainfall than San Anselmo or Novato, and the sustained dampness corrodes exterior lock hardware measurably faster. We see seized cylinders and rust-frozen deadbolts in Fairfax at roughly twice the rate we see in drier Marin communities. We spec marine-grade stainless hardware and treat internals with corrosion inhibitors as standard practice here. Call (833) 294-4584 for a free inspection of your exterior locks.
Often no, but we can usually save the door. Seized cylinders on Fairfax’s pre-war bungalows typically require extraction - the pins and springs have rusted solid inside the plug. We remove the cylinder, decode or replace it, and install a new pinned cylinder in your existing housing or a period-matched replacement. If the wood jamb has swollen, we also adjust or replace the strike plate. The price quoted on the phone is the price on the invoice. Call (833) 294-4584 to describe what you’ve got.
We recommend Schlage B60N deadbolts with stainless steel bolts, Medeco Maxum cylinders with proprietary hardening, and select Kwikset SmartKey units with upgraded internal components for Fairfax’s damp environment. For maximum resistance, we also stock Abloy and Mul-T-Lock marine-grade options. The right lock depends on your door prep, your keying needs, and your budget - we bring samples and explain the tradeoffs on site. Call (833) 294-4584 to schedule.
Yes, though response times run longer than to flat-grid addresses. Our dispatchers route smaller service vehicles for calls to upper Cascade Drive, Bolinas Road-adjacent lanes, and similar one-lane hillside access roads with no turnaround. We plan the approach before we leave, and our technicians carry full stock so we don’t need to return to base. The flat price quoted on the phone includes the drive - no surcharge for difficult access. Call (833) 294-4584 and tell us your street; we’ll give you a realistic ETA.
Yes, with proper prep. Seasonal swelling on Fairfax’s moisture-softened frames changes the door-to-jamb gap, which affects smart lock bolt throw and sensor alignment. We measure the full seasonal range, shim or plane the jamb as needed, and spec smart locks with adjustable bolt throws and robust motor torque - Schlage Encode and Yale Assure units handle this well. We also set mechanical key overrides because electronics and damp Marin winters aren’t always friends. Typical installation runs $220-$340. Call (833) 294-4584 for a free estimate.
