Fast, Reliable Change Door Locks Across Burlingame
Changing door locks in Burlingame typically costs $145 to $385 depending on whether you’re swapping standard cylindrical hardware or working with the 1920s-era mortise locksets common in the Easton Addition and streets around Burlingame Avenue.

When you call (910) 714-4287, a live person answers. We dispatch background-checked, photo-badged technicians to Burlingame from our San Francisco Bay Area office, and the price goes in writing before any work begins.
Why Dunmore Locksmith Is Burlingame’s Preferred Change Door Locks Company
Burlingame homeowners call us because we understand what’s behind their doors before we ever arrive. The city’s housing stock is not interchangeable with the newer subdivisions a few miles south. A 1931 Spanish Colonial Revival on Easton Drive has different lock geometry than a 1960s ranch above El Camino Real, and treating them the same is how trim gets scarred and cylinders get cross-threaded. Our technicians carry mortise cylinder adaptors, replacement escutcheons, and trim in the van, which matters when a key snaps inside a 90-year-old Sargent lock on a Tuesday afternoon. Every technician who arrives at a Burlingame home has been background-checked and identity-verified under the Threshold Standard, and customers receive the technician’s name and photo before the visit. We have served customers under the Threshold Group umbrella since 2007, and every job carries the 365-Day Done Right Promise in writing: if it is not done right, we make it right, and if the repair fails, a second visit is provided at no charge.
Door Lock Installation in Burlingame
Door lock installation in Burlingame means something slightly different than it does in most Peninsula cities. When a homeowner near Sanchez Avenue or Ray Park needs a new deadbolt on a 1938 front door, our tech first checks whether the existing mortise cutout can accept a modern cylinder or whether an adaptor plate is needed to keep the antique escutcheon intact. Installation typically runs $165 to $320 per door, including the new lock, drilling or adapting the bore, and adjusting the strike plate. Homeowners in newer townhomes off Trousdale Drive with standard cylindrical preps fall toward the lower end; original Craftsman doors with thick stiles and odd trim fall higher.
Mortise Lock Cylinder Adaptation
Many Burlingame doors built between 1920 and 1945 use full mortise locksets where the cylinder threads directly into the lock body, not a separate deadbolt above it. When we install new lock cylinders in these doors, we stock adaptor kits for Schlage, Baldwin, and Sargent mortise bodies. Off-the-shelf cylinders rarely seat correctly in the original escutcheons, which is exactly the kind of detail that turns a 20-minute swap into a damaged-door repair if you’re not prepared for it.
Modern Deadbolt on a Vintage Door
Adding a modern deadbolt above an original mortise lock on a 1930s Easton Addition bungalow requires care. The bore must be positioned to avoid the existing lock body and trim, and the new deadbolt’s faceplate often needs to be sized to match a non-standard door thickness. We do this often enough in Burlingame that the process is routine, but it is not a job that rewards a generic approach.
Patio Door Lock Change in Burlingame
Patio door lock change in Burlingame covers sliding glass doors, French doors, and the updated steel-and-glass patio entries common in mid-century ranch homes on the hillside lots above Adeline Drive. A typical patio door lock replacement runs $175 to $345, depending on whether we’re replacing the handle set, the mortise latch, or the foot bolt at the base of a sliding panel. Burlingame’s marine layer means patio door hardware that faces the bay absorbs salt-laden moisture for hours every morning, which accelerates wear on the latch springs and internal pawls.
Sliding Door Handle and Latch Replacement
Sliding patio doors in Burlingame keep a surprising number of homeowners locked out of their own backyards. The latch inside the handle set corrodes, the key cylinder seizes from salt air, or the handle simply strips. We replace the full handle assembly and latch, then adjust the door’s rollers so the latch actually seats.
French Door and Multi-Point Lock Service
French patio doors on older Burlingame homes sometimes carry multi-point locks with rods that throw into the head and sill. When one of these fails, the door may not close at all, which is a problem when the fog rolls in at 5 p.m. We service and replace these systems, matching finish and backset so the patio door’s hardware looks intentional.
Trusted Brands We Service in Burlingame
We install and service Kwikset, Medeco, Yale, and Baldwin hardware across Burlingame. For vintage homes near Burlingame Avenue, we keep Baldwin mortise trim and replacement cylinders in the van so a lock change does not require a week-long parts wait. Medeco high-security cylinders are common in Burlingame condo buildings and multi-tenant properties along El Camino Real where key control matters. Our technicians are factory-authorized to service Schlage, Kwikset, Medeco, Yale, Baldwin, Mul-T-Lock, Sargent, and Abloy hardware, which means warranty work stays valid when we perform it.
Common Change Door Locks Problems We See in Burlingame Homes
- Seized exterior cylinders from daily marine layer exposure. Burlingame sits on the western edge of San Francisco Bay, and the morning fog pushes salt-laden moisture into exterior lock mechanisms, corroding the brass and zinc-alloy cylinder internals faster than a few miles inland. When a cylinder seizes, a key that worked fine last month snaps off inside it, needing extraction before any lock change can proceed.
- Non-standard mortise escutcheons on 1920s – 1940s doors. Homes in the Easton Addition and near Burlingame Avenue carry original Corbin, Sargent, and Yale mortise locks whose faceplates are not standard sizes. An off-the-shelf cylinder won’t sit flush, so we fit adaptor cylinders that preserve the original trim and escutcheon.
- Restricted key systems in dense condo and apartment buildings. Multi-tenant properties around Broadway and Burlingame Avenue use restricted keyways to prevent unauthorized copying. When a unit key is lost or copied against the lease, the entire building’s master key system often needs re-pinning, not just the individual unit cylinder.
- Modern cylindrical deadbolts improperly installed into mortise-cut doors. A previous homeowner or handyman tries to drop a modern deadbolt into a 1930s door with a full mortise cavity, and the bore never lines up. We see the aftermath in Burlingame regularly: visible gaps around the faceplate, a loose cylinder, or trim that won’t sit flat.

FAQs About Change Door Locks in Burlingame
Yes. We change locks on 1920s – 1940s Burlingame homes regularly, and the original escutcheon and trim stay in place. The key is carrying the right mortise cylinder adaptors in the van. When you call (910) 714-4287, we’ll ask what the faceplate looks like so the technician arrives prepared for your specific lock rather than discovering it at the door.
Burlingame’s daily marine layer drives salt-laden moisture into exterior lock cylinders, corroding the internal pins and springs. Lubrication only gummed up the corrosion. The fix is a proper disassembly, cleaning, and replacement of the corroded cylinder, often with a brass or marine-grade cylinder that resists salt better than standard zinc alloy. Call (910) 714-4287 for an exact quote.
Not always. Restricted key systems in Burlingame condo buildings are controlled by a master key hierarchy. Rekeying one unit cylinder without re-pinning the building’s master system can compromise key control for every other unit. We coordinate with your building management or HOA, inspect the keyway, and determine whether a single-unit rekey or a building-wide re-pin is required. Call (910) 714-4287 and we’ll walk you through it.
Yes, but it is not a basic drill-and-mount job. The thicker stiles and original mortise lock body on a 1920s Burlingame door mean most standard smart deadbolt bores won’t align. We use adaptor kits and sometimes custom escutcheon plates to mount a smart deadbolt above the original mortise lock while leaving the antique hardware intact. A typical smart lock retrofit on these doors runs $285 to $485 depending on the door’s thickness and existing cutouts.
No. The price we quote on the phone includes the patio door lock change, the parts, the labor, and the travel to Burlingame. There is no separate patio-door surcharge and no arrival fee added on. Call (910) 714-4287 for a free estimate and a written price before we dispatch anyone.
