Locksmith in Pomona, California
Short answer: Julian's Locksmith is a licensed (LCO7891), insured and bonded mobile locksmith serving Pomona in Los Angeles County from our San Bernardino base, about 32 miles away via SR-210. We handle home, car and business lock and key work on site. Hours: Daily 6:30am–11:30pm. Call (951) 903-3193.

Pomona runs on shared keys. The 2020 census counted roughly three and a half people per household here, and close to half of the city's homes are rented. Put those two facts together and one front door can have a grandparent's key, two teenagers' copies, a cousin's spare and whatever the last tenant never handed back. That is where a lot of locksmith work in Pomona begins, and it's why rekeying and key control come up on so many of our calls.
The rest of the work follows the city's big institutions. Lincoln Park's Victorian and Craftsman homes carry hardware older than anyone living in them. Cal Poly Pomona and Western University of Health Sciences turn over student rentals every year. Pomona Valley Hospital Medical Center anchors a cluster of medical offices along Garey Avenue, and Fairplex fills its lots with tens of thousands of cars for the LA County Fair, drag races and swap meets.
Julian's Locksmith is a licensed mobile locksmith based in University Heights, San Bernardino, about 32 miles east along the 210 Freeway. We bring key machines, rekey pins, door hardware and car key programmers to your curb, quote before starting and check ID before opening anything. We work every day, 6:30 a.m. to 11:30 p.m., weekends included. Call (951) 903-3193.

Lock and key security in Pomona
Most of the security problems we find in Pomona come down to three things: too many keys, tired door frames and doors that get hot.
Key sprawl is the big one. In a city where many households span three generations and almost half the homes are rentals, keys get copied at the hardware counter, lent to relatives, left with contractors and never collected. A lock can be in perfect mechanical shape and still be compromised because nobody knows who holds a copy. Rekeying cuts off every old key without replacing hardware, and a restricted keyway such as Medeco, Mul-T-Lock or Schlage Primus stops casual duplication. Keypad deadbolts help as well, since each person gets a code you can delete.
Frames come second. Houses in Lincoln Park, Hacienda Park and the older blocks off Holt Avenue have century-old jambs, often patched more than once, and a deadbolt is only as strong as the wood behind its strike. In postwar tracts across North and South Pomona, many front doors sit behind steel security screen doors whose locks were never keyed to the house, and sliding patio doors still depend on one small latch.
Heat is the third. July highs here average around 90 degrees, and heat waves have pushed past 110. West-facing metal doors expand until the bolt drags, keypad batteries weaken, and dust from a dry summer packs into pin tumblers. A strike adjustment, a dry PTFE lubricant and a battery schedule handle most of it.
Event weekends at Fairplex add one more layer: crowded lots, valuables left in plain view and push-button cars locked with the fob inside.
Residential locksmith service in Pomona
Residential lock problems in Pomona tend to sort themselves by the age of the house.
In the Lincoln Park Historic District, built between the 1890s and the 1940s, and in neighboring Hacienda Park, we find original mortise locks, rim locks on back doors and doors bored for three different deadbolts over the decades. Our approach is to keep what's worth keeping: clean and repair the mortise body, fit a new cylinder, and add a deadbolt sized to the door's real thickness and backset instead of forcing a standard kit into it. Old hardware that comes off goes back to you.
Postwar ranch homes across South Pomona, North Pomona and the Palomares Park area usually need simpler work. Typical requests are rekeying after a purchase, reinforcing strikes with three-inch screws, adding a foot lock to the slider, and keying the security screen door, side gate padlock and garage entry door to match the front.
Phillips Ranch, first developed in the mid-1960s and built out largely from the 1980s on, has tract homes, townhomes and condos where builder-grade Kwikset and Schlage hardware is still common. Smart locks such as the Schlage Encode, Yale Assure and Kwikset Halo are popular there and anywhere a large household shares one door, because codes can be added or removed without cutting a single key.
For landlords, California Civil Code Section 1941.3 requires working deadbolts on main swinging entry doors. Before any home lockout, we verify photo ID and proof of residence.
Commercial locksmith service for Pomona businesses
Pomona's business locks follow its institutions. Around Pomona Valley Hospital Medical Center on Garey Avenue and Casa Colina Hospital on Bonita Avenue, medical and dental offices need master key systems that let staff into their own suites while keeping records rooms, medication cabinets and server closets on separate keys. Clinics, labs and small offices near Western University of Health Sciences downtown run on the same logic.
Along Second Street, the galleries and studios of the Arts Colony and the shops of Antique Row mostly sit behind narrow aluminum storefront doors with Adams Rite deadlatches, plus roll-up grilles and glass display cases with cam locks. Keyed-alike cam locks and a fresh set of mortise cylinders after a staff change are typical jobs. Holt Avenue's motels, restaurants and auto shops add worn LCN closers, panic bars that no longer latch and padlocked yard gates.
Fairplex brings a seasonal rush of its own: exhibitors and vendors at the LA County Fair and year-round trade shows who need padlocks rekeyed, a cash drawer opened or a storage container secured. In the industrial blocks along Mission Boulevard, the work turns to dock doors, hasps, shrouded padlocks and keypad entry for shipping offices.
We install standalone keypad locks, electric strikes and single-door readers. Networked access control tied to fire alarms or camera systems may need a licensed low-voltage contractor, and we'll tell you when it does. We confirm your authority over the property before opening or rekeying anything.
Car keys and lockouts in Pomona
Fairplex gives Pomona's car calls a character you won't find in many cities. The Pomona Swap Meet and Classic Car Show draws vintage cars and trucks, and their owners sometimes need help with a worn key, a sticky ignition cylinder or a car bought that morning with no key at all. Most pre-transponder vehicles can be keyed by code or by decoding a door lock, and a tired ignition cylinder can often be rebuilt or replaced on site.
Modern vehicles are still the bigger share. Fair days, NHRA weekends and the Cal Poly Pomona parking lots produce plenty of lockouts, and push-button cars occasionally lock with the fob still inside. We open them with air wedges and long-reach tools rather than slim jims, so seals and wiring stay intact. For lost keys, we cut blades and program transponder keys and smart fobs through the OBD-II port for many Toyota, Honda, Nissan, Ford, Chevrolet, Hyundai and Kia models. Some European makes and newer vehicles with secure gateway modules need dealer-only programming, and we'll say so before you wait on us. Every vehicle key requires your ID plus a matching registration, title or bill of sale.
Commuters using the Pomona-Downtown Metrolink station or the Pomona North stop, now shared with the A Line, should keep the spare key at home. And in summer, a fob battery that has been baking on the dashboard can quit in a Fairplex lot.
Neighborhoods we serve in Pomona
Pomona covers about 23 square miles, and each part of it has its own hardware. North Pomona holds Fairplex, Ganesha Park and the hillside streets of Ganesha Hills, along with Pomona Valley Hospital Medical Center and the Pomona North station near Garey and Bonita Avenues. The Palomares Park area along Arrow Highway surrounds the 1850s Adobe de Palomares.
Central Pomona is the historic core. Lincoln Park fills 45 blocks between McKinley Avenue, Towne Avenue, Pasadena Street and Garey Avenue, Hacienda Park adds more early twentieth-century homes nearby, and downtown's Second Street carries the Arts Colony, Antique Row and the Western University campus. Holt Avenue cuts across it all with motels, apartments and small businesses.
The west side belongs to Cal Poly Pomona and the old town of Spadra, where the 1875 Phillips Mansion stands on Pomona Boulevard near the Kellogg Interchange. South Pomona, below Mission Boulevard and along the 60, mixes postwar homes with industrial blocks. Phillips Ranch climbs the hills of the southwest corner between SR-71, Diamond Bar and Chino Hills, with streets like Phillips Ranch Road and Rio Rancho Road.
Getting to you in Pomona
We drive to Pomona from 2544 Rosemary Lane in San Bernardino's University Heights. The usual run is University Parkway to SR-210 West through Rialto, Fontana, Rancho Cucamonga and Upland, then off at Towne Avenue in Claremont and south into North Pomona, Lincoln Park and downtown. That's about 32 miles and roughly 38 minutes with a clear freeway. For Cal Poly Pomona, Spadra and Phillips Ranch, we stay on the 210 to SR-57 South through the Kellogg Interchange, then take Temple Avenue or SR-71 South.
Traffic is the variable. The 210 slows through Rancho Cucamonga at rush hour, the Kellogg Interchange backs up when I-10 is heavy, and fair days in May clog McKinley Avenue and Fairplex Drive. That's why we give you an honest ETA on the phone instead of a promise. We take calls every day from 6:30 a.m. to 11:30 p.m., weekends included.
Local lock and key tips for Pomona
- In a multigenerational Pomona household, keep a simple key log listing who holds copies of the front, back, gate and garage keys. When an adult child moves out, a relative leaves or a caregiver stops coming, rekey or delete that person's keypad code the same week. A smart lock with individual user codes, such as a Schlage Encode or Yale Assure, turns that cleanup into a quick job.
- Plenty of Pomona homes have a steel security screen door in front of the main entry, with its own lock that was never keyed to the house. Ask to have it keyed alike with the deadbolt so one key opens both. Check the frame as well: if the hinge side is held by short screws into stucco, a pry bar can defeat the whole door.
- Heading to the LA County Fair in May or an NHRA weekend at Fairplex? Photograph your parking lot and row, keep the fob in a zipped pocket instead of a bag that gets set down, and give a spare key to someone in your group. We are closed between 11:30 p.m. and 6:30 a.m., so roadside assistance may be quicker on a late night.
- Planning a new deadbolt for an older door in Lincoln Park or Hacienda Park? Measure the door's thickness and its backset, the distance from the edge to the center of the existing hole, before buying anything. Many early doors don't match the standard 2-3/8 inch backset or 1-3/4 inch thickness, and a kit forced into the wrong door can split a stile that's hard to replace.
- Lost the key to your apartment mailbox? If the mailbox bank belongs to your complex, the property manager can authorize a locksmith to replace your compartment lock, and we'll need that approval plus your ID. If the Postal Service owns the unit, the local post office handles the lock instead. Ask your manager which applies before calling anyone, and you'll avoid a wasted trip.
Why choose Julian's Locksmith in Pomona
Before anyone works on your door, check the license. Julian's Locksmith holds California locksmith company license LCO7891 from the Bureau of Security and Investigative Services, and you can confirm it at search.dca.ca.gov. California's Locksmith Act requires that license, and it's the only credential we claim.
The rest is straightforward. We quote before we start and explain what moves the price: the lock brand and grade, how many cylinders need new pins, whether period hardware can be saved and, for cars, the key type and immobilizer. The van carries rekey kits, deadbolts, mortise cylinders, key blanks and programmers, so most Pomona jobs finish in one visit. We ask for ID and proof of ownership or authority every time, which protects you as much as anyone. And when a job belongs with a dealer, a safe technician who has to drill or a low-voltage contractor, we tell you up front.
Frequently asked questions
Do you cover all of Pomona, including Phillips Ranch and the Cal Poly side?
Yes. We cover the whole city: North Pomona and Ganesha Hills around Fairplex, Lincoln Park and downtown, the Holt Avenue corridor, South Pomona, Spadra and the Cal Poly Pomona area, and Phillips Ranch in the southwest hills. That includes the 91766, 91767 and 91768 ZIP codes. Drive time from our San Bernardino base depends on the 210 and the Kellogg Interchange, so we give you a realistic ETA when you call (951) 903-3193.
Can you keep the original locks on my Lincoln Park house?
Often, yes. Many early mortise locks can be cleaned, repaired and fitted with a modern cylinder, which keeps the original knobs and escutcheons on the door. Very old warded locks offer little real security and can't be rekeyed, so we usually leave them in place as decorative hardware and add a properly sized deadbolt beside them. If you're planning visible exterior changes in a historic district, check with the city's planning staff before you start.
I rent near Cal Poly Pomona. Who is responsible for my locks?
Under California Civil Code Section 1941.3, landlords must provide working deadbolts on main swinging entry doors and security devices on windows, so a broken deadbolt is normally the owner's repair. Most leases bar tenants from changing locks without permission, so ask the manager first. In certain situations involving a protective order or similar documentation, Civil Code Sections 1941.5 and 1941.6 require the landlord to change the locks within 24 hours of your written request.
Can you help with a car lockout at Fairplex during the LA County Fair?
Yes, during our open hours. Tell us which lot and row you're in, what kind of vehicle it is and where the keys are, and we'll give you an honest ETA, since fair traffic on McKinley Avenue and Fairplex Drive can slow the last mile. We open most vehicles with air wedges and long-reach tools. Expect to show photo ID that matches the registration before we open the door.
Can you make a key for a classic car I bought at the swap meet?
Usually. Most older cars use mechanical keys with no transponder chip, so we can cut one by code if it's known, or decode a door or trunk lock to work out the cuts. A worn ignition cylinder can often be rebuilt or replaced to match. Bring the signed title or bill of sale along with your ID, because we verify ownership before making any vehicle key, even for a car that isn't registered in your name yet.
What are your hours, and what should I do if you're closed?
We work every day from 6:30 a.m. to 11:30 p.m., weekends included. We're closed overnight, and we aren't a 24/7 service. If you're locked out while we're closed, try a spare with a relative, your property manager's after-hours line or your insurer's roadside plan for a car. Then call us once we open for rekeying, a lock change or new keys.
