Fast, Reliable Change Door Locks Across Daly City
Changing door locks in Daly City usually costs $145 – $285 for a standard lock change, and most jobs are completed the same day. The price goes in writing before any work starts, so you’ll never open the door to a surprise total. If you’re locked out, need locks changed after a tenant moves out, or just realized your 1950s-era hardware has finally given up, call Dunmore Locksmith at (910) 714-4287. We answer live, 24 hours a day.
Why Dunmore Locksmith Is Daly City’s Preferred Change Door Locks Company
Daly City’s housing stock has a fingerprint you won’t find in most Bay Area suburbs: thousands of nearly identical Doelger-era stucco tract homes in Westlake and St. Francis Heights, dense semi-attached rows in Broadmoor, and apartment buildings clustered near Mission Street and John Daly Boulevard. We know these doors. We know that a standard 2-3/8″ backset deadbolt kit often won’t fit a 1952 Doelger passage door, and we carry what’s actually needed.
Our Daly City customers consistently tell us the same thing: the technician we said was coming is the person who showed up. That’s the Threshold Standard, and it’s not optional. Every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When they arrive at your door near Westmoor or Serramonte, they’ll be in a clean marked uniform with a photo ID badge. If someone shows up you weren’t told to expect, that visit is covered at no charge.
Dunmore has served customers since 2007 as part of the Threshold Group family of independent local locksmith businesses. Perry Osgood leads our team, and the promise he stands behind is simple: every job carries the 365-Day Done Right Promise. If something isn’t right, we return at no charge for a full year. That’s not a slogan. It’s written on every job sheet.
Patio Door Lock Change in Daly City
A patio door lock change in Daly City typically runs $175 – $310 depending on the door style. On the city’s west side, toward the ocean side of Skyline Boulevard and in the fog belt around Westlake, patio door locks take a beating from the salt-laden marine layer. The sliding-door mortise locks and flush-mount handles on older Doelger homes often seize internally, and by the time a homeowner calls us, the latch won’t throw or the key won’t turn at all.
Sliding Door Lock Replacement
Most Daly City patio doors use a mortise-style lock mounted in the door edge, not a surface-mounted cylinder. Replacing these means matching the existing mortise pocket depth, which on 1950s and 1960s doors is frequently shallower than modern replacements require. We carry retrofit kits for the older Adams Rite and Weslock-style mortises still found in Westlake tract homes, so the job does not require butchering the door.
Patio Door Handle and Cylinder Matching
Because so many Daly City homes were built with uniform door preps, entire blocks often have the same original hardware. That makes matching easier in one way: we’ve seen your exact patio lock before, dozens of times. But it also means the original cylinders are often too corroded to rekey. We’ll tell you honestly whether rekeying is enough or a full change is the smarter move, with the price in writing before we touch a screw.
Door Lock Change in Daly City
A door lock change in Daly City generally costs $145 – $285 for a standard single-cylinder deadbolt, installed. Entry knobs and levers run $120 – $230, and a full entry set (deadbolt plus knob or lever) typically lands between $240 – $400 with hardware included. Those are real numbers for this market, quoted up front on the phone and honored on the invoice. No call-out surcharge added on arrival.
Deadbolt Replacement on Doelger-Era Doors
If your home sits between Gellert Boulevard, Southgate Avenue, and Westlake Park, there’s a good chance the original door prep is not what a big-box-store deadbolt expects. Many of these doors have backsets closer to 2-3/4″ than the modern 2-3/8″ standard. We carry both sizes, plus the faceplates and strike plates to match the original hole spacing, so a lock change doesn’t leave you with gaps or an unmortised strike.
Entry Knob and Lever Changes
After 60 to 75 years of coastal fog, an entry knob in Daly City often has internal springs that are simply done. The knob spins, the latch drags, or the key works some days and not others. Changing the knob or lever is a 45-minute job when the prep is standard, and a bit more involved on older doors. We’ll tell you which situation you have before we start, and we’ll give you a written price either way.
Trusted Brands We Service in Daly City
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, Abloy, Baldwin, Yale, Mul-T-Lock, and Sargent hardware. For Daly City’s older homes, we commonly stock the Schlage B560 deadbolt and Kwikset’s 660 and 980 series because they’re drop-in replacements for the original builder-grade hardware on Doelger doors. If you want a higher-impact upgrade, a Medeco or Mul-T-Lock deadbolt brings drill resistance and controlled key duplication – a real consideration on a street where half the doors share the same keyway. We keep common parts in our Daly City service vehicles, so most lock changes finish in one visit.
Common Change Door Locks Problems We See in Daly City Homes
- Seized deadbolts from the marine layer. Salt-laden fog off the Pacific works into lock cylinders year-round, and over decades it turns internal springs and pin stacks to crust. A lock that still turned last winter may freeze solid by June, even if it’s barely used.
- Non-standard backsets on Doelger garage-to-interior doors. The attached garage passage doors on many Westlake homes were built with thinner slabs and a 2-3/4″ backset. Stock 2-3/8″ deadbolt kits don’t fit cleanly, and forcing one in means enlarging the bore or leaving the edge weak.
- Landlord-tenant lock changes on Mission Street corridor apartments. After a tenant turns over a unit near Top of the Hill or Crocker, the landlord needs the lock changed and new keys for the next renter. We rekey or replace quickly and issue a written key-receipt so the property owner knows exactly how many keys exist.
- Patio door locks that don’t survive the fog belt. Sliding glass door locks on the ocean side of Skyline face more corrosion than almost anywhere in the Bay Area. The handle set and the mortise lock both need periodic replacement, and cheap aluminum internals fail fastest of all.

FAQs About Change Door Locks in Daly City
Yes, with your landlord’s or property manager’s written authorization, we can change the locks on a rental unit or condo door in Daly City. Many apartment owners near Serramonte and Mission Street ask us to handle lock changes between tenants so they have a clear key-receipt and a record of who holds keys. Bring written permission, and we’ll quote the job up front. Call (910) 714-4287 with the details.
Daly City sits directly in the path of one of California’s most persistent marine layers, and the salt-laden fog condenses on exterior lock cylinders most mornings of the year. That constant salt moisture attacks the springs, pins, and cylinder chambers from the inside, not just the visible face. Locks two miles inland in San Bruno or South San Francisco can last decades without seizing, while the same hardware in Westlake or near the Pacifica border can freeze in a few years. We see the difference all the time.
Maybe not, and that’s exactly why you want a locksmith who knows the Doelger tract homes. Many original garage-to-interior passage doors in Westlake have a 2-3/4″ backset instead of the modern 2-3/8″ standard, plus a thinner door slab. A standard deadbolt kit won’t align properly, and forcing it means drilling a larger bore and weakening the door edge. Our techs carry both backsets and will confirm the prep before installing anything. Your door gets a proper fit, not a hack job.
Rekeying means changing the internal pins in the existing lock cylinder so your old keys no longer work, but the hardware stays. Changing the locks means removing the old hardware and installing new deadbolts, knobs, or handles. If your existing lock turns smoothly and the hardware is in good shape, rekeying usually costs less and gives you full key control. If the cylinder is corroded, worn, or the hardware is 60 years old, replacement is the better call. We’ll inspect and tell you straight, with a written quote either way.
Yes, and doing so is almost always the right option. Patio door locks are mounted in a mortise pocket in the door edge, and the door itself is usually fine. We carry retrofits for the older mortise footprints common on Westlake-era sliding doors, including Adams Rite and Weslock-style locks. You get a new lock, new keys, and a door that still closes true. Call (910) 714-4287 and we’ll quote the patio door lock change over the phone.
