Fast, Reliable Door Lock Repair Across Kentfield
Door lock repair in Kentfield usually costs between $95 and $240 for a standard cylinder or deadbolt service call, depending on whether the lock needs adjustment, a new cylinder, or full mortise-pocket machining on older solid-wood doors. We get to most Kentfield homes inside 90 minutes, and the full price goes in writing before any work starts. Call (910) 714-4287 and you’ll reach a live person who can schedule a background-checked technician sent to you by name and photo before they arrive.
Kentfield is not a typical service area. The homes above Sir Francis Drake Boulevard, the estates along the Corte Madera Creek corridor, the quiet lanes off Bolinas Road: these are properties where a locksmith has to understand mortise lock sets from the 1950s, gate intercom wiring, and high-security key systems, not just swap a Kwikset knob and leave. Our Door Lock Repair team works these homes regularly, and we carry the hardware and tooling that local door conditions actually demand.
Why Dunmore Locksmith Is Kentfield’s Preferred Door Lock Repair Company
Kentfield homeowners call us because the technician at the door is never a surprise. Every Dunmore technician is background-checked, identity-verified, and sent to you by name and photo before the visit. That is the Threshold Standard, and it matters in a community where opening an estate gate to a stranger is a real decision, not a casual one. Perry Osgood, who leads our team, built this process around one idea: you should know exactly who is coming before you turn the handle.
Local reputation in Kentfield rests on getting the odd jobs right. We have repaired original mortise locks on 1940s solid-wood doors off Laurel Grove Avenue, rekeyed restricted Medeco systems on hillside properties above Sir Francis Drake Boulevard, and replaced corroded gate strikes along the creek corridor. The work holds up because we understand what Kentfield’s fog and humidity do to hardware, and we choose components accordingly. Response time to Kentfield is typically under two hours, and every repair carries a written 365-day guarantee. If the repair fails, we return at no charge.
Sliding Door Lock Repair in Kentfield
Sliding Door Lock Repair in Kentfield frequently involves patio doors on hillside homes where the door has settled slightly out of square, binding the lock and wearing the strike plate unevenly. A typical sliding door lock repair or replacement in Kentfield runs $110 to $190, with higher-security multi-point systems on larger doors running $220 to $340. The final number is quoted on the phone before anyone is dispatched, and that is the number on the invoice.
Adjustment vs. Replacement on Settled Doors
Many Kentfield sliding doors sit on foundations that have shifted a fraction of an inch over decades. The handle-operated hook lock then drags against the receiver, and lube alone will not fix the geometry. We realign the strike, shim the rollers if needed, and replace the hook or mortise lock only when the internal pawl is actually worn. That is the difference between a $30 fix and a $200 replacement, and we will tell you which one you need before we touch the door.
Multi-Point Locks on Tall Sliders
Kentfield homes built in the 1960s and 1970s often have oversized sliding glass panels with multi-point locks that throw at two or three points. When one point sticks, the whole lock feels failed. We service the individual gear points, replace the gearbox or keepers as needed, and re-time the throw so the handle moves cleanly. Parts for multi-point hardware are not a same-day item at every shop, but we stock the common profiles for the door types we see repeatedly in Kentfield.
Deadbolt Repair in Kentfield
Deadbolt repair in Kentfield most often comes down to two local failure patterns: a stiff or seized throw from fog-driven oxidation, or a bolt that no longer aligns because the solid-wood door has swelled with Ross Valley humidity. A standard deadbolt repair or replacement in Kentfield runs $95 to $180. A high-security deadbolt cylinder, like a Medeco, runs $180 to $280 installed. Both include the written quote before work begins and the 365-day guarantee.
Fog Corrosion on Exterior Deadbolts
Kentfield sits in the Ross Valley with Corte Madera Creek running through it, and the morning fog persists well after places like Novato have cleared. Exterior deadbolts on north-facing gates and entry doors take the brunt of it. We see cylinders where the brass has dulled and pitted and the bolt throw feels like grinding sand. Cleaning and re-lubricating a corroded cylinder can buy time, but when the pin chambers are pitted, the only honest fix is a new cylinder keyed to match your existing key if possible.
Swollen Doors and Bolt Alignment
Solid-wood statement doors absorb moisture in winter and release it in summer. A deadbolt that worked smoothly in September may barely throw in February because the door has swelled and the bolt no longer lines up with the strike. We bore the strike deeper, reposition it, and in some cases plane the door edge slightly. The repair is exact, and we do not recommend forcing the bolt, which can snap the tailpiece inside the lock body.
Trusted Brands We Service in Kentfield
We are factory-authorized to service and install Schlage, Kwikset, Medeco, and Yale hardware, which covers nearly every lock we encounter in Kentfield. For restricted key systems on gated estates, Medeco is the standard here, and we can cut and issue controlled keys with the proper key-control documentation. We stock common cylinders, tailpieces, and strike plates for same-day repairs in Kentfield, so a mortise lock on a 1950s door does not have to wait for a part shipped from a regional warehouse. Dunmore comes from old words for a great fort, a stronghold built to keep what is inside safe, and that is the standard we service to.
Common Door Lock Repair Problems We See in Kentfield Homes
- Corroded exterior deadbolts and gate strikes. Persistent fog off Corte Madera Creek accelerates oxidation on brass and steel hardware, especially on north-facing entries. The throw stiffens, then seizes, often within five to seven years of installation.
- Original mortise locks in 1940s – 1970s doors. Kentfield’s housing stock includes a large share of solid-wood doors with original mortise lock bodies that modern cylindrical deadbolts cannot replace without machining new pockets or fabricating adapter plates.
- Restricted key system lockouts. Medeco and Mul-T-Lock keys cannot be duplicated at a hardware store kiosk. When one is lost on a gated Kentfield estate, the correct fix is rekeying the pin and tumbler core and reissuing controlled keys, not a cheap copy.
- Gate intercom and access-control failures. Hillside parcels above Sir Francis Drake Boulevard often have low-voltage wiring running to gate locks and intercoms. A door lock issue at the house can tie into a gate release failure, and fixing one without checking the other leaves the problem half-solved.

FAQs About Door Lock Repair in Kentfield
Yes. A mortise lock body from the 1950s can almost always be repaired or replaced without touching the door itself. We disassemble the lock, clean or replace the internal springs and levers, and when the body is beyond saving, we machine a fresh mortise pocket to accept a modern high-security mortise case sized to the existing door. The door stays in place. Call (910) 714-4287 and describe the door; we will tell you what is likely involved and quote a range before scheduling.
Kentfield holds fog longer than drier Marin towns because it sits in the Ross Valley along Corte Madera Creek, and that damp air oxidizes brass and steel lock components faster than the same hardware in Novato or San Rafael. The result is stiff throws, pitted pin chambers, and premature cylinder failure on exterior locks, especially north-facing hardware. It is a real pattern we see repeatedly in Kentfield, and it is why we choose corrosion-resistant finishes and components for exterior work here. Call (910) 714-4287 for an exact quote on your specific lock.
Yes, we rekey restricted Medeco and Mul-T-Lock cylinders in Kentfield, and we issue new controlled keys with key-control documentation so you know exactly how many keys exist for your property. A lost controlled key means the old key should be considered a security risk, not just an inconvenience, so we rekey the pin and tumbler core and provide a new key set. Pricing depends on cylinder count and key profile. Call (910) 714-4287 and we will quote it over the phone.
Most sticking sliding door locks in Kentfield are repairable. The usual causes are door settlement that pulls the strike out of alignment, or internal wear on the hook pawl from years of forcing a misaligned lock. We fix the alignment first, and only replace the lock body when the internal mechanism is genuinely worn out. A typical sliding door lock repair in Kentfield runs $110 to $190. Call (910) 714-4287 and we will give you a firm number before we come out.
Yes. We regularly integrate repaired or replaced door locks with existing alarm panels and smart-home systems in Kentfield, including keypad entry at the gate and front door controlled from one panel. If the gate runs low-voltage access-control wiring, we check that circuit as part of the door lock repair so the two systems talk to each other. Call (910) 714-4287 and tell us what system you have; we will confirm compatibility and quote the full scope on the phone.
