Locksmith in San Dimas, California
Short answer: Julian's Locksmith is a licensed (LCO7891), insured and bonded mobile locksmith serving San Dimas in Los Angeles County from our San Bernardino base, about 34 miles away via I-215. We handle home, car and business lock and key work on site. Hours: Daily 6:30am–11:30pm. Call (951) 903-3193.

Few towns in the San Gabriel Valley wear their history as openly as San Dimas. Downtown still has wooden sidewalks and old-fashioned storefront facades along Bonita Avenue, the 1887 Walker House stands on San Dimas Avenue, and white-fenced multi-use trails follow Via Verde Avenue, Foothill Boulevard and Sycamore Canyon Road. Up in the northern foothills, plenty of lots are big enough for a barn and a pipe corral. At the south end, Frank G. Bonelli Regional Park, Puddingstone Reservoir and Raging Waters draw boaters, campers and summer crowds, while the Foothill and Orange freeways and the new Metro A Line station keep commuters moving.
That spread is why a San Dimas locksmith can't specialize too narrowly. One week could include rekeying a 1970s tract home off Gladstone Street, replacing a rusted padlock on a tack room near Horsethief Canyon Park, cutting a key for a camper's compartment lock beside the lake and opening a minivan in a hot parking lot.
Julian's Locksmith is a mobile locksmith based in University Heights, San Bernardino, roughly 34 miles east on the 210. The van brings key machines, transponder programmers and lock stock to you. We quote before work begins, verify ID and ownership before any lockout or new key, and hold California license LCO7891. Call (951) 903-3193.

Lock and key security in San Dimas
Law enforcement in San Dimas comes from the Los Angeles County Sheriff's Department, which runs its San Dimas Station in town, and L.A. County Fire handles fire and rescue. What shapes day-to-day security more, though, is how open the city is. Many backyards meet a riding trail, a flood-control channel or a slope with nobody behind it. That privacy is part of the appeal, but it also means a side gate or a rear slider can become the entry nobody watches.
Start there. A side gate should self-close and latch, secured with a keyed latch or a padlock through a welded or through-bolted hasp rather than a hook and eye. Sliding glass doors need a secondary lock, a pin through the frame or a bar in the track, because the factory latch on an older slider is mostly a catch. Barns, tack rooms and hay sheds deserve real hardware too. Saddles and power tools are easy to carry to a truck, and a closed-shackle or shrouded padlock resists bolt cutters far longer than an open-shackle bargain lock.
The recreation side of town adds its own pattern. Lots at Raging Waters and around Puddingstone Reservoir fill with parked cars, and anything visible on a seat invites a smashed window. Leave the spare key at home, not in a magnetic box under the bumper.
Finally, the foothill streets off San Dimas Canyon Road and Sycamore Canyon Road sit at the wildland edge, where Santa Ana winds raise fire risk every fall. If your driveway has an electric gate, make sure everyone in the house knows the manual release, and ask L.A. County Fire whether an emergency key switch is expected for your gate.
Residential locksmith service in San Dimas
Most San Dimas homes went up between the 1960s and the 1980s, and many still carry the locks the builder installed. A typical house might have a Kwikset knob and deadbolt on the front, a mismatched Schlage on the garage entry and a slider with a worn latch. Rekeying everything to one key usually comes first; mismatched keyways just mean swapping a cylinder or two. On a door that takes a kick, the strike matters as much as the deadbolt: a reinforced strike plate with 3-inch screws reaching the stud changes how the door holds.
The Town Core around Bonita Avenue is different. Older cottages and bungalows may still use mortise locks with early cylinder or even bit keys, and the city keeps design guidelines for historic buildings there, so check with the Planning Division before replacing an original front door. We can often add a modern deadbolt or upgrade the mortise cylinder while keeping the period trim.
Horse properties along Sycamore Canyon and in the Northern Foothills tend to collect keys: house, barn, tack room, feed shed, arena gate. Rekeyable padlocks let you bring most of them onto one key, or we can set up a master so the farrier and the stable hand open only what they need.
Landlords should remember Civil Code Section 1941.3, which requires working deadbolts on main swinging entry doors and window security in rentals. In mobile home parks, doors are lighter and need hardware made for them, and lever handles help residents with arthritis. We confirm ID and residence before any home lockout.
Commercial locksmith service for San Dimas businesses
Commercial locksmith work in San Dimas splits into a few distinct settings. Downtown, shops and restaurants along Bonita Avenue operate out of older buildings behind those wooden sidewalks, where a heavy back door, a worn mortise lock and a key copied for every employee since opening day are common. Rekeying after staff turnover, then fitting a solid deadbolt or a mortise lock with a high-security cylinder such as Medeco or Mul-T-Lock, takes care of most of it.
The retail centers on Foothill Boulevard and Lone Hill Avenue use aluminum storefront doors with Adams Rite deadlocks, hookbolts and pivot hinges. A door that drags, a latch that won't catch or a closer that slams usually needs adjustment rather than replacement, and a properly set LCN closer keeps the door from being yanked open by a Santa Ana gust.
Along Arrow Highway, light-industrial buildings and contractor shops depend on roll-up door locks, padlocked yards and exit devices. On doors that must stay locked from outside but open freely from inside, a Von Duprin or Sargent panic bar with cylinder dogging is the standard answer. A master key system works well when the owner needs every door and each crew should open only its own area.
Medical and professional offices near San Dimas Community Hospital on Covina Boulevard often want restricted keyways or keypad entry for records rooms and supply closets. Card access and electric strikes are options too, and on larger systems we may coordinate with a licensed low-voltage contractor. We confirm owner or manager authorization before any business lockout.
Car keys and lockouts in San Dimas
Vehicle work in San Dimas follows the freeways, the lake and the horse trailers. Commuters who park at the A Line station on San Dimas Avenue or merge onto the 210 and 57 before sunrise tend to discover a lost key at the worst possible moment, and modern keys make that a bigger job. We cut and program transponder keys, remote-head keys and smart proximity fobs for most makes through the OBD-II port, and we'll tell you up front when a vehicle, often a newer European model, needs dealer-only programming instead.
Puddingstone Reservoir brings boat and personal watercraft trailers, and those come with coupler locks, hitch pin locks and spare-tire locks that go missing along with the boat keys. Horse trailers add tack-compartment and escape-door locks, many of which take common CH751-series keys we can cut on site. Proprietary trailer locks sometimes have to be drilled and replaced.
Heat is the quiet culprit. A fob left on the dash in a sunny lot at Bonelli Park drains quickly, and a CR2032 that seemed fine in spring can quit by August. If your dash flashes a key-battery warning, change the cell before the fob stops talking to the immobilizer.
For lockouts we use air wedges, long-reach tools and Lishi picks, not slim jims, so seals and wiring stay intact. For a new key with nothing to copy, bring ID and a registration or title that matches the VIN.
Neighborhoods we serve in San Dimas
Each part of San Dimas brings its own lock work. Downtown and the surrounding Town Core, roughly the blocks around Bonita Avenue and San Dimas Avenue, mix storefronts with older cottages, so mortise locks, vintage doors and storefront hardware turn up within a few blocks of each other. North of Foothill Boulevard, the Northern Foothills, Horsethief Canyon and the streets up San Dimas Canyon Road and Sycamore Canyon Road hold larger lots, hillside homes and horse properties, where gates, barns and long driveways dominate.
The middle of the city, from Lone Hill Avenue east past Cataract Avenue and along Gladstone Street, is mostly 1960s and 1970s tract housing, which means rekeys, deadbolt upgrades and smart-lock installs. Covina Boulevard adds San Dimas High School, the hospital and its medical offices.
South of Puente Street, the Via Verde neighborhood sits beside Bonelli Park, with white-fenced equestrian lanes, larger homes and quick access to the 57. West San Dimas, also called Mesa Oaks, is a small unincorporated enclave that uses Covina mailing addresses, and we serve it just like the rest of town.
Getting to you in San Dimas
Our base on Rosemary Lane in University Heights is about 34 miles from central San Dimas, roughly 37 minutes with no traffic. The route is direct: University Parkway to I-215 South, then SR-210 West through Rialto, Fontana, Rancho Cucamonga, Upland, Claremont and La Verne. The San Dimas Avenue exit drops us near downtown, the Walker House and the A Line station, while the Lone Hill Avenue exit serves the west side and Arrow Highway. For Via Verde, Bonelli Park and Raging Waters, we take SR-57 South to the Via Verde exit.
Real drive times can run longer. The 210 slows through Rancho Cucamonga and Upland at rush hour, summer traffic stacks up around Raging Waters Drive, and fire or wind closures sometimes affect the canyon roads. When you call, we'll give you an honest ETA based on your address and that day's conditions.
Local lock and key tips for San Dimas
- Barn air is hard on locks. Dust, hay chaff and ammonia from the stalls dull plated padlocks and stiffen their shackles, so tack rooms and feed sheds do better with solid brass or stainless padlocks rated for outdoor use. Every couple of months, puff dry graphite or a PTFE lubricant into the keyway and work the key a few times. Skip oily sprays, which hold grit.
- Towing to Puddingstone Reservoir? Order your coupler lock, hitch pin lock and spare-tire lock keyed alike, and record the key code stamped on the lock or key somewhere that isn't on the boat. Keep one spare trailer key in the tow vehicle and another at home. A floating keychain is great for the boat key but easy to leave behind on the dock.
- Planning a day at Raging Waters or Bonelli Park? Water and heat are tough on key fobs, so keep yours in a locker or a sealed bag instead of a swimsuit pocket, and never hide a spare under the car. If you lock yourself out late, remember that we close at 11:30 p.m., so roadside assistance may be quicker then.
- Living with an original mortise lock in the Town Core? Have new keys cut from the original key, not from a copy of a copy, since each generation drifts a little from the factory cut. If the knob or lever has started to droop, the internal spring is likely worn and can often be rebuilt. Forcing a stiff old lock is how keys snap inside it.
- Before Santa Ana season, test the manual release on any automatic driveway gate in the foothills and show everyone at home how it works. Put together a labeled spare kit with house, barn, gate and vehicle keys that's easy to grab during an evacuation, and consider a combination lockbox so a neighbor can let the horses out if you can't get home.

Frequently asked questions
Do you serve every part of San Dimas, including Via Verde and the Northern Foothills?
Yes. We cover the whole city, from the Town Core and the Bonita Avenue shops to the hillside streets off San Dimas Canyon Road, the tracts along Gladstone Street and Lone Hill Avenue, and Via Verde beside Bonelli Park. We also serve the unincorporated West San Dimas enclave, where homes carry Covina mailing addresses, along with the parking areas around Puddingstone Reservoir and Raging Waters. Most of the city uses the 91773 ZIP code.
Can you put my house, barn and tack room on one key?
Usually, yes. Pin tumbler locks that share a keyway can be rekeyed to match, and rekeyable padlocks or padlocks with interchangeable cores can join the same key. If the house uses Schlage and the barn uses Kwikset, we swap a cylinder so everything shares one keyway. Many inexpensive padlocks can't be rekeyed at all, so we may suggest keyed-alike replacements. A master key setup also works if hired help needs the barn but not the house.
Can you add a deadbolt to an older house in the Town Core without ruining the door?
In most cases, yes. On an original wood door we check the thickness, the stile width and whether an old mortise pocket is already cut, then pick a deadbolt with the right backset so the bore doesn't weaken the door. Sometimes the better approach is a new mortise lock with a modern cylinder in the existing pocket. If you're replacing the door itself or changing visible trim, review the city's Town Core design guidelines first.
Do you work on boat trailer, horse trailer and RV locks?
Yes. We handle coupler and hitch pin locks, horse trailer tack and escape-door locks, RV entry and compartment locks, and the tow vehicle itself. Many compartment locks use common CH751-series keys we can cut on the spot, and some trailer locks can be rekeyed to match the rest of your keys. High-security or proprietary trailer locks may need drilling. We'll ask for proof that the trailer or vehicle is yours before opening or cutting anything.
Are you open on weekends?
On Sundays, yes. We're open from 6:30 a.m. to 11:30 p.m., the same hours we keep Monday through Thursday. Saturdays get those same hours too, and so do Fridays. If you get stuck while we're closed between 11:30 p.m. and 6:30 a.m., your auto club or your insurer's roadside service is usually the quickest fix for a car, and a spare key with a trusted neighbor is the best backup for a house.
What will you ask for before opening a door or making a key?
A government-issued photo ID, plus something linking you to the property or vehicle: a lease, utility bill, deed or tax record for a home, and a registration or title matching the VIN for a car. For a business, the owner or an authorized manager needs to be present or reachable. That's how California's Locksmith Act, administered by BSIS, expects locksmiths to work, and it keeps strangers from talking their way into your house or barn.
