Locksmith in Altadena, CA
Altadena locksmith work carries a specific set of demands you won’t find in Pasadena or La Cañada. The community’s 1920s-to-1950s housing stock, the Santa Ana wind grit, and the ongoing recovery from the January 2025 Eaton Fire all shape what we do on any given call. Dunmore Locksmith serves Altadena with written prices, named technicians, and a 365-day guarantee on every job. Call (910) 714-4287 and a live person answers, any hour.
Why Altadena Homes Are Different
Altadena is an unincorporated LA County community, not a city. That matters for locksmith work because permits and jurisdiction flow through County Sheriff’s Altadena Station rather than a municipal police department, and county-level rules apply without any city licensing layer on top. For homeowners, it means the locksmith you hire needs to understand county requirements, not just trade practice.
The housing stock compounds the challenge. Most of Altadena’s core neighborhoods are dense with craftsman bungalows and post-war ranch homes built between the 1920s and 1950s. We routinely open doors with original mortise lock sets, skeleton-key entry hardware, and single-cylinder knobs that never had a modern deadbolt installed. Working on those locks requires different tools and different training than swapping a Kwikset cylinder on a newer Pasadena door. After the Eaton Fire, new builds now rise on lots directly beside century-old hardware, so a single street can demand both antique restoration and modern high-security installation in the same week.
The climate adds another layer. Altadena sits at the San Gabriel Mountain foothills and takes some of the most intense Santa Ana wind events in the LA Basin. The dust and grit those winds carry accelerates wear inside deadbolt cylinders, and the thermal cycling causes wood-framed doors to rack seasonally. That means a lock that worked fine in August may bind by December. Homeowners in the Very High Fire Hazard Severity Zone are also pushing toward fire-rated steel doors, which need specific strike plates and hardware ratings to function correctly.
Our Main Altadena Services
These four services cover the vast majority of what Altadena homeowners and business owners call us for, and each has its own dedicated page with deeper detail.
Residential Locksmith in Altadena
Most residential calls in Altadena start with an older door that won’t latch or a lockout on a craftsman bungalow with an original mortise set. We rekey, replace, and upgrade home locks, and we’re comfortable working on the older hardware that makes Altadena homes distinctive. If you’re entering the post-Eaton-Fire recovery market as a buyer, rekeying should be step one after closing. Learn more on our Residential Locksmith in Altadena page.

Door Lock Repair in Altadena
Santa Ana grit gets into deadbolt cylinders and seasonal racking throws door alignment off, so repair calls in Altadena are frequent and often repeat. We repair loose cylinders, stuck latches, worn strike plates, and handles that spin without engaging. A repair that’s done properly should outlast the season. If it doesn’t, our 365-day guarantee means a second visit at no charge. Details are on the Door Lock Repair in Altadena page.

Change Door Locks in Altadena
Changing door locks in Altadena often means more than swapping a knob. On older homes, we’re replacing a single-cylinder knob with no deadbolt and adding the deadbolt the home never had. After a tenant change, a caregiver transition, or a separation, changing the locks is the standard move, and we quote a flat price before any work starts. See the Change Door Locks in Altadena page for the full breakdown.

Commercial Locksmith in Altadena
Altadena’s commercial work runs from small retail on Lake Avenue to churches and community buildings, many of which carry older commercial hardware. Storefront doors, high-security cylinders, master key systems, and access control all fall under this service. We survey and schedule commercial jobs rather than dispatch, and every quote is a written scope with a flat per-lock price. Visit the Commercial Locksmith in Altadena page for specifics.

Brands We Service in Altadena
We’re factory-authorized to install and service Schlage, Kwikset, and Medeco hardware, and we stock common Schlage and Kwikset parts locally for same-day turnaround in most Altadena neighborhoods. Older mortise sets often need brand-specific components, so having the right parts close by shortens the job considerably. See our brands page for the full list.

These ranges reflect what Altadena homeowners typically pay for common jobs. Every quote is written before work begins, and there’s no call-out surcharge added on arrival.

What pushes prices up in Altadena is primarily the age of the hardware. A mortise set on a 1930s bungalow takes longer to rekey than a modern Kwikset knob, and if parts need to be sourced for an antique lock, that adds to the total. We tell you the full price on the phone before anyone is dispatched, and that price is what appears on the invoice.
