Locksmith in Cotati, CA
Locksmith work in Cotati, CA covers a compact city of roughly 7,500 people where most homes date from the 1960s through the 1990s, with newer subdivisions mixed in along the eastern edge. The housing stock means we see a lot of original door hardware that has outlived its useful life, along with owners who have lost track of how many copies of their keys are floating around after tenant turnover or a home sale. We’re Ridley Locksmith & Security, part of the Garrison Partners family, and every job here runs on a written price before work starts and a written guarantee covering the repair for one full year. Call (956) 275-7388 and a live person answers.
Why Cotati Homes Are Different
Cotati sits at the junction of Highway 101 and Highway 116, which means quick access to Sonoma State University and the broader Rohnert Park area, but also a steady churn of rental turnover that drives more rekey requests than you’d expect for a city this size. Summer temperatures regularly push past 90 degrees, and the dry heat does a number on wood door frames and entry hardware. Doors swell and settle over the years, strike plates drift out of alignment, and deadbolts that worked fine in March start binding in September when the frame has shifted.
The older homes near downtown Cotati, especially around La Plaza and the streets off Old Redwood Highway, often have solid wood doors with hardware that’s been painted over multiple times. That’s not a problem in itself, but it does mean extracting and replacing hardware takes more care than a quick swap. Newer developments east of Highway 101 trend toward more standardized hardware, though we still see a mix of cheap builder-grade locks that fail early. If you live in an HOA community, check your CC&Rs before scheduling exterior hardware changes – some of the newer subdivisions have standards for finish and style on front-facing locks.
Our Main Cotati Services
The two calls we get most in Cotati are rekey requests after a tenant moves out and residential lock repairs or upgrades, with commercial work running a close third along the Gravenstein Highway corridor. Each service has its own Cotati page with full pricing and detail.
Rekey Locks in Cotati
A rekey changes the internal pins inside your existing lock cylinders so old keys no longer turn, while the hardware itself stays in place. In Cotati, landlords and property managers call us the day a lease ends, but homeowners also rekey after a roommate leaves, a contractor’s key was never returned, or a car key and house key went missing together. We can also key all your exterior doors alike so one key works every lock. The full rundown on pricing and turnaround is on our Rekey Locks in Cotati page.

Residential Locksmith in Cotati
Residential work in Cotati runs from straightforward deadbolt replacements to full exterior lock upgrades on older homes that still have the original knob-and-key setups. We see a lot of Baldwin and Kwikset hardware in the older neighborhoods, and we stock common parts to keep turnaround fast. Whether a door lock has failed, a key snapped off in the cylinder, or you want to upgrade to a higher-security setup, our Residential Locksmith in Cotati page covers what to expect and what it costs.

Commercial Locksmith in Cotati
Commercial work in Cotati centers on the retail and office spaces along Old Redwood Highway and the industrial units near Gravenstein Highway. We handle master key systems, high-security cylinders like Medeco and Mul-T-Lock, door closers, and storefront hardware. Every commercial job gets a written scope and a flat per-lock price before we start, so a bookkeeper can see exactly what the invoice will say. See our Commercial Locksmith in Cotati page for the details.
