Kentfield sits at the base of Mount Tamalpais where orographic lift funnels 55-65+ inches of rain annually onto these wooded properties. That’s double what San Rafael sees, and the salt air rolling through the Marin Headlands compounds the damage. We’re the Lock Installation & Rekey in Kentfield company that accounts for this in every recommendation, from the grade of steel we specify to the weatherproofing we build into electronic installs.

We know the local housing stock intimately: the 1920s Craftsman estates on Woodland Road, the mid-century ranches tucked into Kent Woodlands, the heavy custom doors with original mortise locksets that require specialty fitting rather than big-box hardware. This isn’t generic locksmith work. It’s Kentfield-specific expertise built over four decades.
Our Lock Installation & Rekey Services in Kentfield
Smart Lock Installation
Smart locks in Kentfield need more than connectivity - they need environmental hardening. The persistent humidity and salt air here destroy standard electronic components in 18-24 months if not properly specified. We install Yale and Schlage smart locks with marine-grade gaskets and sealed battery compartments, and we verify Bluetooth and Wi-Fi signal strength through the dense redwood and oak canopy that can interfere with wireless protocols on these wooded lots. For Kent Woodlands estates with heavy custom doors, we reinforce jambs before mounting to account for seasonal swelling that would otherwise throw alignment off within months.

Electronic Lock & Keyless Entry
Keypad entry controllers on Kentfield’s long private driveways fail regularly from moisture intrusion - it’s one of the most common calls we get from Kent Woodlands properties. We replace these with weatherproof electronic locks rated for sustained high-humidity exposure, and we hardwire where possible to eliminate battery dependency in a climate where cold fog can sap voltage. Our keyless entry installations for main residence doors include humidity sensors and auto-lock timing adjusted for owners who may be gardening or walking the property in weather that changes fast coming off Mount Tam.

Biometric Lock Installation
Biometric locks present a particular challenge in Kentfield’s climate. Fingerprint sensors on unprotected hardware corrode at the contact points, and the fine particulate from decomposing redwood duff can abrade optical readers. We specify biometric units with sealed, capacitive sensors and install them under covered entries wherever the architecture allows. For the exposed gate locks common on Kent Woodlands driveways, we recommend biometric as secondary authentication only, paired with a weather-hardened keypad or RFID fob system.

Rekeying & Key Duplication
Rekeying a Kentfield estate home after purchase requires more than pin replacement. We inspect every cylinder for salt-air corrosion that may not yet have caused failure but has compromised internal tolerances. If a Schlage or Kwikset cylinder shows pitting, we recommend replacement with a stainless-steel Medeco core rather than rekeying - the upfront cost is higher, but the 5-7 year service life in this climate justifies it. We also master-key systems for properties with separate guest cottages, pool houses, or staff quarters common in the Kent Woodlands area.

Trusted Brands We Service in Kentfield
We stock and install Schlage, Medeco, Kwikset, and Yale hardware with local inventory for Kentfield customers - no waiting on Bay Area distribution warehouses. Our trucks carry stainless-steel and marine-grade options specifically for this climate, not just the standard catalog. When a Kentfield customer needs a Baldwin smart lock matched to existing period brass or a Medeco high-security cylinder that won’t corrode shut in two winters, we have the parts and the fitting experience. Turnaround matters here. A seized deadbolt on a rainy night is not a “next week” problem.
Common Lock Installation & Rekey Problems We See in Kentfield Homes
- Salt-air corrosion seizes cylinder pins within 1-2 years. Standard Schlage and Kwikset hardware installed without climate consideration develops internal corrosion that makes rekeying impossible - full replacement is required. We see this constantly in homes within a mile of the Marin Headlands fog corridor.
- Seasonal frame swelling binds deadbolts and snaps keys. The heavy rainfall keeps wooden door frames in near-constant expansion-contraction cycles. Deadbolts that turn smoothly in September bind hard by January, and forcing them snaps keys off in the cylinder - a service call that could have been prevented with proper strike plate adjustment and humidity-tolerant hardware.
- Gate lock keypad controllers fail from moisture intrusion. Kent Woodlands properties with long private driveways rely on electronic gate entry that wasn’t built for 60+ inches of annual rain. We upgrade these to weatherproof IP65-rated systems with drainage-rated enclosures.
- Original mortise locksets in 1920s-1950s estates need specialty fitting. These aren’t off-the-shelf replacements. The door prep, backset, and faceplate dimensions differ from modern standards, and the heavy doors require reinforced strike boxes. We fabricate custom solutions rather than forcing incompatible hardware.

FAQs - Lock Installation & Rekey in Kentfield
The combination of 55-65+ inches of annual rainfall, salt air from the Marin Headlands, and persistent high humidity under the redwood canopy corrodes standard brass and steel lock cylinders at roughly twice the rate of drier Bay Area ZIP codes. We recommend upgrading to stainless-steel Medeco cores or marine-grade Schlage hardware with sealed gaskets. Call (833) 294-4584 for a free inspection of your current cylinders.
Yes, if installed with proper jamb reinforcement and strike plate adjustment to accommodate seasonal movement. We specify Yale and Schlage smart locks with flexible mounting systems and verify alignment across wet and dry seasons. The key is pre-installation assessment of your specific door’s swelling pattern, which we measure during our free estimate. Call (833) 294-4584 to schedule.
Rekey immediately upon purchase, then inspect cylinders every 2-3 years for corrosion that would make rekeying impossible. In Kentfield’s climate, we often find that 1920s-1950s hardware with original brass cylinders needs replacement rather than rekeying by the second ownership transfer. Our $89 Seasonal Tune-Up includes corrosion assessment. Call (833) 294-4584 to book.
Yes - we specialize in weatherproof electronic gate locks for Kent Woodlands estates, including hardwired keypad controllers and RFID systems that eliminate battery failure in sustained humidity. We also integrate with existing intercom systems. Typical range is $380-$650 depending on wiring run and controller grade. Call (833) 294-4584 for an exact quote.
Medeco for high-security cylinders with stainless-steel construction, Schlage for smart locks with sealed electronic components, and Baldwin for period-appropriate hardware with marine-grade finishes. We avoid standard-grade Kwikset for exposed exterior doors in this climate - the internal corrosion rate simply doesn’t justify the savings. Call (833) 294-4584 to discuss the right match for your specific doors.
We recently rekeyed a 1920s Craftsman on Woodland Road in Kent Woodlands where the original Schlage deadbolt had seized from salt-air corrosion. We replaced the cylinder with a stainless-steel Medeco core and installed a Baldwin smart lock on the front door, accounting for the swollen jamb by adjusting the strike plate alignment. It’s the kind of job we do regularly in 94914 - not just installing locks, but fitting hardware to a specific place and its particular weather.
