Locksmith service in Pomona
If you need a locksmith in Pomona, this page explains what One & Only Locksmith does here and how a call runs.
Pomona is in the eastern San Gabriel Valley about thirty miles east of Los Angeles, bordered by San Dimas, La Verne and Claremont to the north, Montclair and Chino to the east, and Chino Hills and Diamond Bar to the south. Downtown Pomona, including the former Pomona Mall pedestrian street with its Antique Row and arts district, is the historic core. The Fairplex hosts the L.A. County Fair; Cal Poly Pomona and Western University of Health Sciences are the major campuses. Phillips Ranch, a largely residential neighborhood, has grown since the 1980s. I-10, CA-57, CA-60 and CA-71 serve the city, with two Metrolink stations.
We are a mobile service: a technician comes to your address in Pomona for home, business, vehicle and emergency lock and key work. The dispatch line, (888) 492-0666, is answered around the clock. The dispatcher confirms the address and the problem and gives you an ETA before anyone is sent.
Local notes for Pomona
Corridors: Foothill Boulevard (Route 66) and Downtown Pomona (former Pomona Mall). If you are on one of these, tell the dispatcher the nearest cross street; curb access and parking can be tight, and that affects where the technician can stop.
Reference points: Pomona Fox Theater, Phillips Mansion, Lincoln Park Historic District and Pomona Valley Hospital Medical Center. Naming the closest one helps when a street address is new or unnumbered.
Housing stock: Historic neighborhoods such as the Lincoln Park Historic District alongside the newer, mostly residential Phillips Ranch (1980s onward). Older houses often carry mortise locks or worn cylinders; mention the age of the door and lock when you call so the technician brings matching parts. Hillside and canyon addresses can be hard to find at night; give the dispatcher the cross street and whether there is street parking at the house. Post-war tract houses usually have standard cylindrical locks, which means rekeying and keying alike are straightforward and new deadbolts fit without re-boring the door. Newer construction commonly ships with builder-grade hardware; if you want a stronger deadbolt the door is usually already bored to the standard size.
Commercial districts: Downtown Pomona / Antique Row / arts district and Fairplex. For storefront and office calls, have the business name and suite number ready and tell the dispatcher whether there is a loading dock, lobby desk or after-hours entrance.
Getting to you: I-10, CA-57, CA-60 and CA-71 all serve the city, and Metrolink stops at Pomona-Downtown and Pomona-North.
