Fast, Reliable Commercial Locksmith Across Los Altos
Commercial locksmith work in Los Altos follows a pattern unlike most Bay Area cities. We’re not mostly opening locked doors. We’re rekeying brand-new construction before move-in, replacing builder-grade hardware that was never meant to last, and getting smart locks to actually talk to Control4, Crestron, and Z-Wave hubs. If you need a commercial locksmith who understands Los Altos homes, call Dunmore Locksmith at (910) 714-4287. A live person answers, any hour.
Our Commercial Locksmith team serves Los Altos with written pricing before any work begins, background-checked technicians sent to you by name and photo before arrival, and every job covered by our 365-Day Done Right Promise. The price we quote on the phone is the price on your invoice. No arrival surcharges, no after-the-fact totals.
Why Dunmore Locksmith Is Los Altos’s Preferred Commercial Locksmith Company
Los Altos homeowners tend to research before they call. They read specs. They ask about Z-Wave versus Zigbee. They want to know who is coming to the door before they open it. That matches how we work. Every Dunmore technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When the technician rings the bell, they show a photo ID badge at the door. If someone arrives who you were not told to expect, that visit is covered at no charge. That is the Threshold Standard, and it has been our operating rule since 2007 under the Threshold Group umbrella.
Perry Osgood leads our team, and the reputation in Los Altos reflects a simple fact: written prices, named technicians, and a guarantee in writing. Reviews from Los Altos customers consistently call out the same things: the technician arrived when promised, the price did not change, and the lock work held. For commercial work, that reliability matters even more. A home office on Los Altos Avenue or a professional practice near Loyola Corners cannot afford a lock that fails on a Friday afternoon.
High Security Locks in Los Altos
High security locks are the standard we install most often in Los Altos commercial spaces and home offices, where the default hardware on a new build rarely meets the owner’s actual security needs. These are cylinders and deadbolts built to resist picking, bumping, and drilling, and they use restricted keyways so blanks cannot be copied at a hardware store. In Los Altos, a typical high security deadbolt installation runs $180 to $420 per door depending on the cylinder grade and whether you need key control. Medeco and Mul-T-Lock restricted key systems run higher, usually $350 to $700 for the first door with the key-control system set up.
Restricted keyways for key control
If you run a home office in Los Altos and have ever handed a key to a contractor, a housekeeper, or a part-time assistant, you have lost control of that key. A restricted keyway means the blanks are only cut by us, and we keep a ledger of who holds each key. No one walks into a big-box store and gets a copy made.
Commercial-grade deadbolts that meet ANSI Grade 1
Builder-grade deadbolts on new Los Altos construction are often not ANSI Grade 1 rated. They cost the builder under $40 and fail under repeated forced entry attempts. We replace them with Schlage B660 or Medeco Maxum deadbolts, which are rated for commercial use and hold up to years of daily cycles.
Commercial Door Repair in Los Altos
Commercial door repair in Los Altos often starts with a door that will not latch, or a deadbolt that binds, or a panic bar that no longer retracts cleanly. The cause is sometimes the lock, but in Los Altos it is just as often the frame. Dry-season soil shrinkage across the Santa Clara Valley shifts door frames on older slab-foundation ranch homes, and a deadbolt that will not throw is frequently a misaligned strike plate rather than a broken cylinder. A typical commercial door repair in Los Altos runs $120 to $280 for strike plate adjustment, hinge tightening, and latch realignment. Full panic bar installation on a commercial door runs $400 to $850.
Panic bar installation and repair
Los Altos has a growing number of professional offices, small clinics, and studio spaces, and any door on an exit path needs a panic bar that works every single time. We install and repair rim-style and vertical rod panic bars, and we check the fire-rating requirements on the door before we touch hardware. A panic bar that sticks is a code violation and a real liability.
Smart lock and access control integration
New Los Altos construction frequently arrives with electronic access control that was installed by a builder who never finished the programming. The lock drops off the Z-Wave network. The app loses control. The builder’s key still opens the door. We rekey the cylinder, set a fresh master code, and pair the lock properly with your hub so the automation panel gets real status from the deadbolt. This is not a standard locksmith call in most cities, but in Los Altos it is routine for us.
Trusted Brands We Service in Los Altos
We are factory-authorized to install and service Schlage, Medeco, and Yale hardware, from commercial cylinders to electronic deadbolts. Los Altos homeowners bring us wine cellar doors with old Baldwin mortise locks, home offices with Kwikset smart code deadbolts, and front entries with Schlage Encode units that never got paired correctly. We stock common parts and cylinders locally so a rekey or cylinder swap is often done in one visit, not two. When you call, tell us the brand and model on the lock face and we will tell you over the phone whether we carry the parts in the van.
Common Commercial Locksmith Problems We See in Los Altos Homes
- Builder’s keys still active after handover. A just-completed custom home changes ownership, but the construction key set was never retired. Anyone who worked on the house, or any subcontractor who kept a copy, can still open the door. We see this on new builds throughout Los Altos, and the fix is a full rekey before you move anything in.
- Smart locks dropping off Z-Wave or Zigbee networks. The builder paired the lock once, or never. The hub loses the node, the app shows “unavailable,” and the homeowner assumes the lock is broken. The lock is usually fine. The pairing and firmware are not.
- Deadbolt misalignment from dry-season frame shifting. Older ranch homes in Los Altos on slab foundations see the ground settle and shrink in summer. The door frame shifts by a few millimeters. The deadbolt binds. A homeowner calls thinking the lock failed, but the cylinder is fine and the strike plate needs realignment.
- Builder-grade deadbolts wearing out fast. New Los Altos construction often includes locks that cost the builder under $40 per door. Within a year or two, the latch sticks, the tailpiece loosens, and the key gets harder to turn. These are not security failures so much as hardware failures waiting to happen.

FAQs About Commercial Locksmith in Los Altos
No, not until the lock is rekeyed. Builder’s keys are typically part of a construction key system, and there is no way to know how many copies exist or who still holds them. We rekey every cylinder on a new Los Altos home before the owners move in, and we can add a restricted keyway at the same time so future copies cannot be made without your authorization. Rekeying a typical new home runs $95 to $180 for the first cylinder plus $20 to $35 per additional cylinder, quoted in writing before we start. Call (910) 714-4287 to schedule the rekey before the moving truck arrives.
Usually yes. The problem in most Los Altos homes is the Z-Wave or Zigbee pairing, not the lock hardware itself. We re-pair the lock to the hub, update the firmware, and verify that the deadbolt reports its status correctly to the automation panel. If the lock is a builder-grade unit that cannot hold a reliable pairing, we will tell you and give you a written price for a Schlage Encode or Yale Assure replacement before doing anything. The diagnostic and re-pairing runs $95 to $180 per lock. Call (910) 714-4287 and describe what the app shows; we will tell you what we think over the phone before anyone is dispatched.
Yes, high security locks are a core part of our work in Los Altos, where many professionals run offices out of converted garages, ADUs, and dedicated wings of their homes. We install Medeco and Mul-T-Lock restricted key systems so only you can authorize key copies, and we can key your office to a separate master while keeping the rest of the house on a different key. A full restricted key system typically runs $350 to $700 for the first door. Call (910) 714-4287 and we will give you a written quote for the doors you need.
In Los Altos, especially on 1950s to 1970s slab-foundation ranch homes, the more common cause is dry-season soil shrinkage shifting the door frame. The deadbolt and strike plate fall out of alignment, and the bolt binds against the plate. The fix is usually strike plate realignment or minor hinge adjustment, which runs $120 to $280, not a new lock. We check the cylinder and the frame alignment before recommending anything. Call (910) 714-4287 and describe the sticking; we will tell you what is likely happening and what the repair typically costs in Los Altos.
Yes, and in Los Altos this is one of our most common requests. Many homeowners here travel frequently for work or keep the property as a second home, and they need scheduled keypad codes for housekeepers, contractors, and house-sitters. We program keypads and smart locks with codes that expire on a set date, or codes that only work during certain hours. Programming typically runs $95 to $180 per lock, quoted in writing. Call (910) 714-4287 and we will set up the schedule you need before your next trip.
