Mobile Key Duplication for San Dimas Homes, Offices and Rentals
Short answer: To get keys duplicated at home in San Dimas, call Julian's Locksmith at (951) 903-3193, gather the keys you want copied, and have ID ready that matches the property. We drive out every day from 6:30 a.m. to 11:30 p.m., cut the copies on site and test them in your locks before we leave.

Honest limits make a service better. Mobile key duplication handles most ordinary keys in San Dimas: house, padlock, mailbox, cabinet and many commercial keys. It can't make everything. Restricted keyways need authorization and sometimes a factory order. Some high-security blanks are available only through the manufacturer. Car keys with chips involve programming, which is covered on other pages. Julian's Locksmith will tell you on the phone which category your keys fall into, so you aren't standing at the door waiting for a copy the van can't produce. Call (951) 903-3193 and describe what you have.
What to know first in San Dimas
Where the work happens matters more than people expect. A single-family driveway is easy. A third-floor apartment, a gated community, an office suite behind a reception desk, a storage lot with a keypad gate and a hospital campus each add small logistics: parking for the van, gate codes, a contact who can approve the work. Tell us when you call. Give the gate code or the guest-list name, the building and suite, the nearest cross street and who will meet us at the door. We carry the machine wherever the work is easiest, sometimes the van, sometimes a kitchen table, sometimes a back office. A stable surface, decent light and a little elbow room are all we ask. With access sorted out, the visit is mostly cutting and testing, and the schedule stays tight for everyone behind you. For multi-building properties, a quick photo of the entrance, or a note about which building is which, helps us reach the right door the first time.
Work included on a typical visit
- Driveway, porch and kitchen-table visits. Most mobile key duplication happens at someone's home. We park, knock and set up where the work goes fastest: the driveway, the porch, a kitchen table or the van's own bench. You keep an eye on your keys the entire time, and the first test happens a few steps away at your own front door.
- What rides in the van. Stocking a van is a balancing act: enough blanks for the keys most homes use, but not a warehouse. We lean toward the profiles seen most in Southern California houses and apartments. If your key is rarer, a description on the phone tells us whether to bring a special blank or order one.
- Apartment complexes, gated communities and parking lots. Carports, stacked garages and long walks from the lot are all workable. We carry the keys we need to the door and keep the machine near the van. If the complex uses a restricted keyway or a building-standard key, the property manager has to authorize extras, and we tell you before cutting anything.
- Job sites and crew key sets. Contractors, rehab crews and builders often need matching keys for a house under renovation: front door, garage, gate padlock, jobsite box. We cut crew sets on site, label them by role and keep the owner's master separate, so the homeowner can collect the crew keys at the end of the job.
- Padlock and gate keys at storage lots, barns and yards. Padlock keys don't live at the house; the locks sit on a gate, a shed or a barn. We meet you at the lock, read the brand and any code stamped on the body, and cut the keys where they're used. Each key is tested in the actual padlock before we leave.
Local factors in San Dimas
Commuters leave before shops open and get home after they close. Our schedule starts at 6:30 a.m. every day and runs until 11:30 p.m., so a visit can happen before work or after the drive home. Meet us at the driveway, hand over the key ring, and have copies tested before you head out along SR-57. Friday and weekend visits keep the same hours.
Family homes make for easy mobile visits: wide driveways, a kitchen table and plenty of keys to untangle. Ask us to come on a weekday morning or an evening, whichever fits school and work. We test every copy at the door, and you end up with a labeled set per person instead of one key everyone borrows and nobody returns.
Inland summers make driveway work harder on everybody. Metal keys left on a sunbaked porch burn fingers, and heat-swollen doors can make a good copy feel tight. We schedule hot-weather visits for the cooler parts of our day when possible, work in shade, and test copies once the lock has cooled. Early appointments, from 6:30 a.m., help. Shade and a bottle of water make a difference for everyone.
Situations this covers
- Picture a woman recovering from knee surgery in Horsethief Canyon who wants spare keys for her daughter and a neighbor. Driving isn't allowed yet. We'd bring the machine to her porch, cut both copies, test them at the door at her pace, and show her the numbered tags so she can tell the sets apart later.
- Consider a restaurant owner in San Dimas who finds that the back door key is stamped Do Not Duplicate. On the phone we'd explain the authorization step, schedule a first visit to confirm the keyway and the owner's authority, and return with the finished keys once the order arrives. It takes longer than a simple copy, but no uncontrolled duplicate walks out.
- Picture a nurse in San Dimas who works nights and sleeps through shop hours. She needs spare keys for a roommate before a trip. We start at 6:30 a.m. every day, so she calls after her shift, meets us on the porch, watches the copies get cut and tested, and is asleep before the van pulls out.
- Say a landlord with six rental units off Lone Hill Avenue wants a copy of every unit key for a new manager. We'd meet at the property, read each unit's key, cut copies on the van's bench and test them in each door during one walk-through. The manager receives labeled bundles, and the landlord keeps a sheet listing which keys were made.
How the visit works
- Call with your key list and location. Call (951) 903-3193 and tell us how many keys you want copied, what they open and where you'll be. Mention anything unusual: Do Not Duplicate stamps, a gated entry, a lease clause or a worn key. That lets us load the van with the right blanks.
- Get a quote and an honest arrival estimate. Quote and timing are separate questions. The quote depends on the keys, the number of locks and the distance. The arrival estimate depends on traffic and the day. Ask about both, and ask what could change either. A clear answer now prevents surprises later.
- Gather the keys and clear the way. If a landlord, HOA or building manager has to approve extra copies, get that permission ahead of time. A forwarded text or email is often enough. It keeps the visit from stalling at the door and spares you a second trip.
- Arrive, verify and read the keys. The check at the door is short but real. We want to know the keys belong to the person asking or that the person has authority. For businesses and rentals, that may mean a quick call or a document. Then we study the key itself, not just glance at it.
- Cut at the van or on your doorstep. Because the machine is with us, small problems get fixed immediately. A cut that comes out a hair shallow is redone. A blank that doesn't seat right is swapped. Nothing leaves our hands until we're satisfied with it, and you aren't waiting on a callback.
- Test in your locks, label and settle up. Before we leave, we recap: how many keys were cut, which locks they fit, which key is the master, and whether any lock felt worn. If we noticed something that needs attention, we note it, quote it separately and leave the decision with you.
What affects the cost
- Time of day within our hours. Our schedule runs every day from 6:30 a.m. to 11:30 p.m. Calls very early or late can price differently from a midday visit because of scheduling and traffic. You hear the number before we drive.
- Whether the key can be finished on the van. Standard residential keys finish on site. Restricted, laser-cut or manufacturer-controlled keys may need an ordered blank and a second visit. The extra trip, the blank and the wait all affect the total. We tell you which category your key falls into during the first call.
- Other work added to the visit. While we're at your door, a sticking deadbolt, a loose strike plate or a lock that needs rekeying may show up. Each is optional, quoted separately and best handled in the same trip so you don't pay for a second drive.
Every job gets a clear quote before any work starts. Call (951) 903-3193 with the details and we'll tell you what to expect for your situation in San Dimas.
What not to do
- Waiting until moving day to think about keys. One key and a truck on the way is the classic crunch. Book a visit a few days ahead so copies, a rekey decision and testing all happen before the pressure peaks.
- Booking too late on a Saturday night. Our schedule ends at 11:30 p.m., and we are closed overnight. A request at 3:30 for a drive across the region probably won't fit. Call early, or plan for Sunday morning from 6:30.
- Handing over a single battered key and nothing else. A cleaner spare, or a key code from the lock's packaging, can make a better copy. Gather everything you own before we arrive and let us choose the best starting point.
Practical tips before you call
- Label copies at the visit, not later. A dot of paint or a numbered tag takes seconds while we're standing there and saves guesswork afterward. Skip addresses and names on tags, since they help the wrong person if a ring is ever lost.
- Hold back one key as the master. Hand us your cleanest original, say it's the master, and keep it unused afterward. Copies come from it, everyone else carries the copies, and you always own a good key to cut from. Store it somewhere other than your key ring, such as a small safe or a file drawer.
- Gather every key in one place before we arrive, including the ones you think are dead, and leave them on their rings, since the grouping often tells us which key belongs where. Dumping the drawer on a table lets us test them against your locks and often shows you can retire half of them. Fewer, better keys is the real goal of the visit.
- Tell us where the van can park. A loading zone, a visitor spot or a space outside the gate: say which, and mention any permit or time limit. If the street is metered or permit-only, say that too, and we'll plan around it. In dense areas around Horsethief Canyon Park and San Dimas Dog Park, a minute of parking planning saves a long walk carrying a machine.

Frequently asked questions
How do I prepare for a mobile key duplication visit?
Gather every key you want copied in one place, including the original of any key you want to keep as a master. Note which door each key opens and how many copies you want. Have photo ID that matches the property, a gate code if needed, and any permission from a landlord or HOA. That preparation shortens the visit and keeps the quote accurate.
Will you test the copies in my locks?
Always. Every copy goes into the lock it was made for and is turned several times with the door open and closed. If a key drags, we adjust or recut on the spot. A copy that works on the bench but binds in the door isn't finished, and testing at your property is the main reason to choose a mobile visit over a counter. We also note any lock that feels worn, so you can decide what to do about it.
What if a copy doesn't work at my door?
Tell us before we leave and we'll fix it right there, since the machine is in the van. We check the blank, the cuts and the lock itself, because sometimes a worn cylinder is the culprit. If a key stops working later, call (951) 903-3193. We'll work out whether the cut, the blank or the lock is at fault.
Can you make keys at more than one address in a single trip?
Often, yes. We plan a route, handle each address in turn and give you one summary. Stops that are close together share the drive, while widely separated ones may be better split across two days. Tell us all the addresses when you call (951) 903-3193 so we can quote the combined visit and bring the right blanks for each location.
What is mobile key duplication?
It's key copying that comes to you. Instead of carrying keys to a shop, the locksmith arrives with a key machine, blanks and finishing tools, cuts the copies at your address and tests them in your locks. Julian's Locksmith offers mobile key duplication across San Dimas. We quote the job before driving, and we check ownership before cutting.
Do you work evenings and weekends?
We work every day from 6:30 a.m. to 11:30 p.m., weekends included. We are closed overnight, and we aren't a 24/7 service. If you need a visit on a Saturday night, call early so we can say honestly whether the drive fits before 11:30 p.m. Otherwise, Sunday morning is a good option.
How far is San Dimas from your base?
San Dimas is about 34 miles from our San Bernardino base, roughly 37 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
