Fast, Reliable Commercial Locksmith Across Fairfax
Commercial locksmith work in Fairfax, CA typically runs $95 – $180 for a standard commercial rekey, $145 – $310 for high-security cylinder installation, and $220 – $480 for panic bar or commercial door repair, with most commercial lockouts arriving within 45 – 60 minutes of your call. Those are the honest numbers we quote on the phone before anyone is dispatched, and they hold as the final invoice. We know Fairfax’s commercial buildings because we work inside them every week, from the shops along Bolinas Road to the offices tucked behind Sir Francis Drake Boulevard. If a lock has failed or a key snapped in a door this morning, call (910) 714-4287 and a live person will answer immediately.
Dunmore Locksmith is the Threshold Group member business serving Fairfax, and our approach to commercial work is built around one thing: the price goes in writing before our technician touches a lock, and the job is covered for a full year under the 365-Day Done Right Promise. If the repair fails, we return at no charge. That is the contract, word for word, on every invoice.
Why Dunmore Locksmith Is Fairfax’s Preferred Commercial Locksmith Company
Fairfax business owners call us because our technicians understand what this town’s climate does to commercial locks before they arrive. The valley damp that drifts along Fairfax Creek between Sir Francis Drake and Broadway doesn’t exist in drier spots like Kentfield, and it changes the diagnosis. We don’t sell a replacement when a seized cylinder can be freed, rekeyed, and put back to work. That honesty builds the kind of reputation that keeps a commercial locksmith in steady rotation across Fairfax’s downtown and the light-industrial units off Center Boulevard.
Every technician we dispatch to Fairfax is background-checked and identity-verified under what we call the Threshold Standard. Before the visit, you receive the technician’s name and photo. At the door, they show a photo ID badge. If someone shows up who you were not told to expect, that visit is covered at no charge. For a Fairfax business owner handing over alarm codes and back-door keys, that verification matters as much as the repair itself.
Our response time to a commercial storefront in downtown Fairfax is typically 45 minutes from your call. Calls are answered by a live person 24 hours a day, every day of the year. No voicemail trees, no chatbot. You will speak to a person who knows the difference between a Schlage and a Medeco by sound of the name alone.
High Security Locks in Fairfax
High Security Locks in Fairfax are not a luxury add-on. They are a response to a specific local reality: the town’s commercial buildings skew toward older, wood-framed storefronts with original or early-generation lock hardware that a determined bump key or a pry bar can defeat in seconds. In Fairfax, upgrading to a high-security cylinder from Medeco, Mul-T-Lock, or Schlage Primus means a restricted keyway, drill-resistant pins, and a key that cannot be duplicated at a hardware store without your authorization card.
A high-security cylinder installation on a Fairfax commercial door runs $145 – $310 per lock, depending on cylinder format and the number of keys cut. Rekeying an existing high-security system runs $95 – $180 per cylinder. Full price is quoted in writing before we begin, and every installation carries the 365-Day Done Right Promise.
What to Expect on a High-Security Job
We start by checking the door’s existing backset, faceplate dimensions, and whether the frame is pre-drilled or mortise-cut. On Fairfax’s older commercial doors, particularly pre-WWII storefronts on Bolinas Road, the existing cut often won’t accept a modern cylinder without a strikeplate adjustment or a door-edge re-bore. We identify that before ordering hardware, not after.
Restricted Key Control for Business Owners
If you have had an employee leave with keys in hand, restricted key control solves the problem permanently. You decide who can duplicate a key, and no one gets a copy without your authorization. In a small town like Fairfax, where the same key might open a back office, a storage shed, and a delivery gate, that control is the difference between a key and a liability.
Commercial Door Repair in Fairfax
Commercial Door Repair in Fairfax almost always starts with the door itself, not the lock hardware. This town gets 40+ inches of rain in a wet year, and by late December the original fir and redwood doors on downtown storefronts and cottage-style commercial buildings have absorbed enough moisture that the bolt binds mid-throw. The lock is not broken. The door has swelled around it. Our techs carry planes, chisels, and sanders alongside the key cutters because a proper repair here means removing a shave of wood, re-cutting the strike mortar, and resetting the strikeplate geometry so the bolt throws clean.
Commercial door repair in Fairfax typically runs $145 – $260 for strikeplate resetting and door-edge planing, and $220 – $480 when the repair includes re-hanging, hinge replacement, or door closer adjustment. The full price is written before we start and there is no call-out surcharge added on arrival.
Signs Your Commercial Door Needs Adjusting
If you have to lift the handle, shoulder the door, or pull slightly to get the bolt to retract, the frame has shifted. That is a strikeplate alignment issue. It gets worse through Fairfax’s wet season and it wears out the cylinder faster every time you fight it.
We Save the Hardware First
We do not sell a replacement where a repair will hold. That is particularly true on Fairfax’s vintage commercial doors, where the brass faceplate or mortise body is part of the building’s character. If it can be freed, rekeyed, and adjusted, that is the job we quote.
Trusted Brands We Service in Fairfax
We are factory-authorized to install and service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware. For Fairfax commercial work, we keep the most common Schlage and Yale commercial cylinders, faceplates, and panic bar parts stocked in our vans, because a parts run to a distributor in San Rafael can add an hour to a job. That means a Schlage deadbolt on a Center Boulevard office or a Yale panic bar on a Bolinas Road shop can usually be repaired same-day without a second visit. When a Medeco or Mul-T-Lock restricted cylinder needs a factory key, we handle the authorization and key control paperwork so the turnaround is as short as the system allows.
Common Commercial Locksmith Problems We See in Fairfax Homes
- Seized cylinders from valley damp. Fairfax’s sheltered valley traps marine air, and the persistent winter wetness corrodes lock cylinders from the inside. A commercial deadbolt that is only four or five years old can seize solid. The fix is freeing the cylinder and rekeying, not replacing the entire assembly.
- Winter-swollen doors trapping the bolt. By November and December, the original fir and redwood doors on older Fairfax commercial buildings have absorbed enough rainfall that the deadbolt binds mid-throw. Forcing the key only strips the cylinder and bends the tailpiece. The real fix is strikeplate geometry and door planing.
- Modern deadbolts dropped into pre-WWII mortise cuts. Fairfax has dozens of commercial buildings whose original doors were cut for 1940s and 1950s mortise locks. A modern cylindrical deadbolt will not line up with the faceplate or backset without a retrofit, and the installation fails on fit, not on the lock.
- Gate and bench locks corroded on hillside lots. Many Fairfax commercial properties climb the town’s slopes, and their detached gates, storage sheds, and delivery entrances sit in damp shade all winter. Those locks are usually the first to seize. We see it every rainy season.

FAQs About Commercial Locksmith in Fairfax
A 1940s mortise lock that has jammed from Fairfax’s valley damp can often be saved and rekeyed, provided the internal mortise body is not cracked and the cylinder pins are recoverable. We remove the cylinder, free the seized pin and tumbler, rekey to a fresh key, and clean out the corrosion. If the brass faceplate is intact but the internal mechanism is beyond service, we can sometimes rebuild the cylinder with a compatible mortise replacement while keeping the original faceplate. If the body is cracked through, honest answer: it needs replacement. Call (910) 714-4287 and we will quote the repair before you decide.
Fairfax sits in an inland Marin valley that funnels coastal moisture and traps marine air, and the town regularly records 40+ inches of annual rain. That damp sits inside lock cylinders and works on the pins, springs, and tailpiece from the inside, especially on exterior gates, hillside benches, and doors that never get direct sun. Locks that would last a decade in Kentfield or Corte Madera can seize in four years in Fairfax. It is a failure of environment, not product quality, and it is the most common diagnosis we make in this town.
Yes, in most cases the lock is not the problem. The redwood or fir door has absorbed winter moisture and swelled enough that the bolt no longer lines up with the strikeplate. We plane the door edge, re-cut the strike mortise, and adjust the strikeplate geometry so the bolt throws clean. We do this without replacing the cylinder or the hardware, unless the cylinder has also been damaged by repeated forcing. The repair is covered under the 365-Day Done Right Promise if the same problem returns within a year.
Yes. Our standard approach to a commercial lockout in Fairfax is non-destructive first: we pick or bypass the lock using the cylinder’s actual pin configuration, and we only drill as a last resort. When a lock has picked up Fairfax valley corrosion or a key has snapped in the cylinder, non-destructive entry may not be possible, and we will tell you that before cutting. After entry, we can rekey the existing cylinder or replace it, and the entry work and repair are covered under the same written quote.
Yes. We design and install master key systems for Fairfax commercial buildings, from small retail storefronts on Bolinas Road to multi-unit offices near Sir Francis Drake Boulevard. A master key system lets you give each tenant or employee a key that opens only their door, while your key opens all of them. We also install high-security cylinders from Medeco, Mul-T-Lock, and Schlage Primus with restricted key control, so no one can duplicate a key without your authorization. Call (910) 714-4287 for a written scope and flat per-lock pricing.
