Our Residential Locksmith Services in Fairfax
Lock Rekey
Rekeying is often the smartest choice after a move, a lost key, or a change in household members. In Fairfax, though, rekeying isn’t always straightforward. Many Craftsman bungalows still carry original or first-generation locksets with obsolete keyways that have worn beyond spec. We’ve learned to ask the right questions over the phone - age of home, brand markings, keyway shape - so our technician arrives with the correct pins and replacement options. When the keyway is too far gone, we’ll explain why a new Schlage or Medeco deadbolt makes more sense than forcing a rekey that won’t hold. Our $89 Seasonal Tune-Up includes cylinder lubrication and strike-plate adjustment, which helps prevent the corrosion-driven seizing we see so often in this valley.
Deadbolt Installation
Fairfax’s damp microclimate destroys standard deadbolts faster than almost anywhere in Marin County. We install marine-grade hardware and back it with our 90-Day Done Right Promise. On hillside homes with moisture-softened foundations, door frames shift seasonally. A deadbolt that lines up in September may bind by January. Our techs check jamb condition, shim where needed, and set strike-plate depth to accommodate winter swelling. We carry Schlage, Medeco, Mul-T-Lock, and Baldwin in the truck, so the right lock goes on the right door - not just what was on the shelf.
Residential Lockout
Getting back into your home without damaging the lock or door takes more than a wedge and a rod. In Fairfax, lockouts often involve corroded cylinders that won’t turn even with the correct key, or deadbolts jammed by swollen jambs after weeks of rain. On a hillside lane off Bolinas Road, we serviced a 1930s Craftsman whose front deadbolt had seized completely due to years of corrosion from the valley’s heavy fog and rain. Our tech replaced the corroded Schlage cylinder with a marine-grade Mul-T-Lock, then realigned the strike plate on the moisture-swollen jamb - a job that required extra time for the narrow, one-lane access. We dispatch compact vehicles for these calls. A standard van might not make the turn on upper Cascade Drive or the steeper lanes above downtown.
Lock Change
Sometimes replacement is the only honest answer. Original Fairfax hardware, decades of corrosion, or a failed rekey attempt all lead here. We remove the old lockset, repair damaged wood if needed, and install new hardware with proper backset and face-bore alignment. For seniors and veterans, we apply a permanent 5% discount. If your repair totals over $250, ask about our $50 standing offer.

Common Residential Locksmith Problems We See in Fairfax Homes
- Seized exterior cylinders from valley moisture. Fairfax’s position in a sheltered inland valley yields some of the highest annual rainfall in central Marin County, causing exterior lock cylinders and strike plates on its dominant 1920s-1940s Craftsman homes to corrode and seize far faster than in nearby drier towns like San Anselmo or Novato. Annual lubrication prevents most failures.
- Deadbolt misalignment after winter rains. Wooden jambs on hillside homes absorb moisture and swell, throwing deadbolt-strike alignment off by an eighth of an inch or more. The bolt binds, the key won’t turn smoothly, and forcing it risks snapping the key or damaging the cam.
- Obsolete keyways that can’t be re-pinned. Original or first-generation hardware is still common on Fairfax bungalows. When the keyway has worn beyond spec, rekeying is impossible. We carry replacement locksets that match vintage door prep without requiring new holes.
- Access delays on narrow hillside lanes. Many residences above downtown Fairfax are reached only by narrow, one-lane hillside lanes with no turnaround. A lockout call on streets like those off Bolinas Road or the upper Cascade Drive area can require a smaller vehicle and adds significant response time, a dispatch reality that locksmiths serving flat-grid towns like San Rafael’s west side never have to plan around.

FAQs - Residential Locksmith in Fairfax
Your cylinders are corroding from sustained moisture. Fairfax sits in an inland valley that traps coastal fog and records measurably higher annual rainfall than neighboring communities like San Anselmo or Novato, and its dominant housing stock of 1920s-1940s Craftsman cottages and bungalows means exterior lock cylinders, strike plates, and deadbolts corrode and seize far faster than in drier nearby towns. Annual lubrication and marine-grade hardware replacements solve most repeat failures. Call (833) 294-4584 for a tune-up quote - estimates are free.
Sometimes, but not always. Original or first-generation hardware is still common on these homes, meaning locksmiths frequently encounter obsolete keyways and worn-out locksets that can’t simply be re-pinned. We inspect the keyway condition first; if it’s worn beyond spec, we’ll explain why a new Schlage or Medeco deadbolt is the honest recommendation. Call (833) 294-4584 and we’ll help you figure out which path makes sense.
We dispatch compact vehicles for these calls and build extra response time into our estimate. Many residences above downtown Fairfax are reached only by narrow, one-lane hillside lanes with no turnaround - a lockout call on streets like those off Bolinas Road or the upper Cascade Drive area can require a smaller vehicle and adds significant response time, a dispatch reality that locksmiths serving flat-grid towns like San Rafael’s west side never have to plan around. Our techs also carry specialized tools for seized cylinders common on these exposed hillside homes. Call (833) 294-4584 and tell us your street - we’ll confirm vehicle fit and ETA.
Your wooden jamb is swelling from moisture absorption. The town’s position in a sheltered inland valley traps moisture and yields some of the highest annual rainfall totals in central Marin County; this sustained dampness oxidizes exterior lock hardware quickly and causes wooden jambs to swell in winter, turning routine lockouts into extraction jobs when cylinders have corroded in place. We shim strike plates and set bolt depth to accommodate seasonal movement. If your deadbolt binds every January, the fix is usually a 30-minute adjustment, not a new lock. Call (833) 294-4584 for a free estimate.
We do, but we check door condition and prep first. Aging wood door frames that swell seasonally, routinely throwing deadbolt alignment off and complicating standard re-key or replacement jobs, can also stress smart lock mechanisms with their precise motor tolerances. We verify jamb stability, backset compatibility, and Wi-Fi signal strength before recommending specific models. For Fairfax’s damp climate, we favor smart locks with weather-resistant ratings and physical key override. Call (833) 294-4584 to discuss whether your door is a good candidate.
