Why Dunmore Locksmith Is Tiburon’s Preferred Commercial Locksmith Company
Dunmore comes from old words for a great fort, a stronghold built to keep what is inside safe. That name matters here. Tiburon’s commercial work isn’t the standard storefront rekey most locksmiths build their schedules around. It’s gated driveway entrances, detached workshops half a switchback up the hill, pool cabanas, and wine rooms in custom homes. Our technicians have been serving this kind of property since 2007 as part of the Threshold Group family, and we run every job through the Threshold Standard: background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. You know exactly who is walking onto your property before the gate opens.
The Commercial Locksmith team that arrives in Tiburon is the same team that handles high-security cylinders and access systems for the wealthiest zip codes in California. We answer phones live 24/7, quote in writing before work starts, and put a 365-day written guarantee on every repair. If a lock we install fails within the year, we come back at no charge. That’s not marketing language. It’s the enforcement mechanism behind the name.
Master Key System in Tiburon
A Master Key System in Tiburon usually means one key that opens the gate, the detached workshop, the main house, and the pool cabana, while tenant or staff keys open only the doors they’re assigned. On steep peninsula lots, this isn’t a convenience. It’s the difference between carrying a janitor’s ring of four or five keys up a flagstone path in the fog, and one key on a single ring that does everything.
Keying Multiple Detached Structures in One Visit
Most Tiburon commercial and estate properties have three to six separate locks spread across outbuildings. A return visit means a second drive down the two-lane peninsula, through Belvedere, or back up the hill. We plan for that. Our master key estimates for Tiburon include every cylinder on the property in one scope, so we don’t leave a gate unkeyed because the owner forgot to mention it. Our system is built on restricted keyways from Medeco or Schlage Primus, so nobody can copy a key at a hardware store without your authorization. Pricing for a full master key system on a four-door property with gate access typically runs $380 to $750, depending on cylinder count and whether we’re retrofitting existing hardware or installing new.
One Key for Owners, Restricted Keys for Staff
Housekeepers, landscapers, contractors, and weekend guests all need access, but not the same access. We build a hierarchy: the owner’s key opens everything; the housekeeper’s key opens the main door and service entrance; the pool maintenance key opens only the cabana and equipment gate. If a key is lost, we rekey the affected cylinder and issue a new key without redoing the whole system. That’s not possible with contractor-grade Kwikset cylinders that any Tiburon hardware store will copy for $2.
Mortise Lock Replacement in Tiburon
Mortise Lock Replacement in Tiburon usually starts with a call from a homeowner whose 1970s-era hillside house still has the original mortise lock on the front door, and the deadbolt won’t throw. These locks house the latch and bolt inside a rectangular pocket cut into the door edge, a design built to last, but not in salt air. The internal springs, levers, and the cylinder itself corrode more quickly within a mile of Richardson Bay than they would five miles inland in San Rafael.
When to Replace Rather Than Repair
If a mortise lock has seized from oxidation, forced, or the keyway is ground down from twenty years of sandy keys, rebuilding it often costs more than replacing it with a new commercial mortise unit from Baldwin or Yale. Replacing the entire mortise lock body in Tiburon, including a new high-security cylinder, typically runs $290 to $520 depending on door thickness and whether we need to enlarge the existing pocket. A new cylinder alone in an existing mortise lock runs $85 to $150.
Upgrading to High-Security Cylinders
Most originals on Tiburon homes are standard pin-and-tumbler cylinders, and many have been picked before. We upgrade to restricted Medeco or Schlage Primus cylinders when we replace the lock body. You get key control cards that prevent unauthorized duplication. No local hardware store has the blanks. That one change does more for a waterfront property than any new deadbolt face on the same old cylinder.
Trusted Brands We Service in Tiburon
We’re factory-authorized on the hardware lines Tiburon properties actually use: Medeco, Mul-T-Lock, Schlage Primus, Kwikset, Yale, and Baldwin. That matters because the mid-century ranch homes and newer luxury rebuilds on the peninsula are not consistent. One street has original Baldwin mortise sets from 1972. The next has a Schlage Primus system installed by a San Francisco security integrator. We stock cylinders, tailpieces, and mortise cassettes for these brands in our bay-area service vehicles, so a failed cylinder on a gate off Tiburon Boulevard doesn’t mean waiting a week for a special order. If it’s not in the truck, we order direct and have it within two days.
Common Commercial Locksmith Problems We See in Tiburon Homes
- Seized gate lock cylinders from salt fog. Year after year, the exposed lock on a driveway gate that doesn’t get used during the week seizes by late winter. The cylinder pins corrode in place. A crew without the right pick set drills it, destroying a $180 to $250 premium cylinder. We do non-destructive entry first, then replace with a marine-rated lock body and a weather sleeve.
- Piecemeal keying across separate visits. A landowner in the hills above Richardson Bay calls one company for the front door, another for the shop, and the gate installer had his own key. Now there are three keys that all look the same. We rebuild these into one master key system in a single visit, so the owner leaves with one key that works every door on the property.
- Builder-grade Kwikset and contract hardware on exposed gates. Some of the newer luxury reconstructions in Tiburon, the ones built fast in the last decade, were spec’d with commodity deadbolts meant for interior use in a dry climate. The salt-laden bay air eats the internal pin and tumbler assembly and pits the finish within two years. We replace them with ANSI Grade 1 deadbolts with a marine-grade finish, rated for heavy exterior duty.
- Weekend and part-time residences with dead smart batteries. A notable share of Tiburon homeowners live primarily in San Francisco and use the property on weekends. A keypad or smart lock with a dead battery, sitting unused for two weeks in fog, is a lockout waiting for the Friday night arrival. We retrofit these with encrypted keypads from Yale or alarm-grade locks that log every entry.

FAQs About Commercial Locksmith in Tiburon
Yes. We build a master key system so one key operates every cylinder on the property: gate, workshop, detached garage, pool cabana, and main house. Owner keys open everything; restricted keys can be limited to specific doors for staff or guests. For a gated estate off Tiburon Boulevard, we do this in a single visit, quoting the full system before work begins. Call (910) 714-4287 for an exact quote with your door count and cylinder types.
Not necessarily. In most cases the cylinder has corroded from salt fog exposure and we can do a non-destructive entry, free the mechanism, and rebuild the cylinder. If the lock body itself is rusted through or the keyway is destroyed, replacement is the honest option. A new marine-grade gate lock with a premium cylinder in Tiburon runs $185 to $340 installed. We tell you which is which on the phone with a photo, before any service charge applies.
Yes, we stock Medeco, Mul-T-Lock, and Schlage Primus cylinders in our service vehicles serving the Tiburon peninsula. These are restricted keyways. When we install them, you’ll get key control cards and no hardware store in Tiburon can duplicate the keys without your signature. If we need a specific tailpiece or mortise cassette the truck doesn’t have, we order direct and typically have it on the peninsula within two days.
The marine fog that rolls off Richardson Bay deposits salt on exposed hardware year-round. Inland Marin towns like San Rafael don’t see the same rate of cylinder seizure and finish degradation that Tiburon’s waterfront and hillside properties do. Locks that worked in summer seize by late winter. The fix is not to lubricate them (which just traps more salt) but to replace the cylinder and, where the lock body is exposed, install a marine-grade housing and weather sleeve.
Yes. Our phone line is answered by a live person 24 hours a day, every day of the year, including weekends and holidays.
