Ontario, San Bernardino County
A Locksmith for Your Whole Apartment Building in Ontario
Short answer: Start with the front door. In most Ontario apartment buildings, every current and former resident has held a key to it, so rekeying the shared doors gives the biggest security gain for the least work, and no unit lock is touched. Julian's Locksmith audits who holds keys, rekeys the common doors and issues new keys with a record. Call (951) 903-3193 to book a walk-through.

Some doors in an apartment building exist to stop strangers, and some exist to let residents out fast. Good hardware does both; bad hardware does neither. Walk your Ontario building and look for the warning signs: a chain on a stair door, a keyed deadbolt on the inside of a rear exit, a closer that no longer pulls the door shut, a wedge holding open a door whose latch drags. Each one is a safety problem and a security problem at once. An apartment building locksmith can fix most of them, including closers, latches, exit devices and strikes. Julian's Locksmith will also tell you honestly when something belongs to a fire contractor or inspector instead. Call (951) 903-3193.
How this works in Ontario
Working inside an occupied building is mostly choreography. Common-area work, such as the front door, stair doors, laundry room or gates, never requires entering a unit, so residents mainly need notice and new keys. Unit-level changes are different: if the unit locks are being rekeyed or are master-keyed, we need either the resident home or a proper entry notice from the owner. California law presumes 24 hours of written notice is reasonable for non-emergency entry, so we plan around the notice the owner serves instead of showing up unannounced. Our order is simple. Make the shared doors secure first, because they protect everyone. Then do the units in batches by floor or hallway, so crews and residents aren't in each other's way. New keys go to residents against a sign-off, with ID, so a former tenant can't collect them. Nothing is left half-done at the end of a day, since the building has to be safe at night.
What we can do on-site
- Rekeying the common doors only. Common doors don't always share one cylinder type. We handle a mix of mortise, rim, key-in-knob and padlocks in one visit, and bring them to one key or two depending on who needs access. Padlocked doors get a proper hasp and a shrouded padlock, since a loose hasp invites cut locks.
- Stairwell, corridor and roof-access doors. Fire-rated doors carry a label, usually on the hinge edge, and the label limits how much a door can be cut or altered. Before we prep for a new lock, we read that label and match the hardware to the rating. A latch that doesn't match can leave a door that fails an inspection and fails in a fire.
- Laundry, trash, storage and utility rooms. These doors are where keys multiply. Residents need the laundry room, staff need the trash and storage rooms, and the meters belong to the utilities, which often want their own access. We set each door on the key it should have. The laundry vendor owns the coin machines and their locks, so we handle only the room door.
- Pool, spa and courtyard gates. Courtyard gates are different: they keep strangers out of a shared garden, not toddlers out of a pool. A keyed or keypad latch with a closer is enough in most cases. We help you choose by asking how often a code would need to change, who might lend it and how many guests come through each week.
- Mailrooms, package rooms and mailbox compartments. A mailroom is often the one shared door with no closer and a latch worn smooth. Residents come and go with armfuls, so the door gets propped. A closer without a hold-open feature, a stronger strike and a lock that engages when the door shuts keep a thief from following a resident inside.
What's different about Ontario
Dense rental areas of Ontario hold the buildings this page is about: walk-up courtyards, garden-style complexes and three-story corridor buildings, often with hardware from several renovations. The most common problems are front doors held open with wedges, laundry and trash rooms on forgotten keys and a manager's master that nobody has counted. If that describes your building near West Ontario, an audit is a sensible first visit.
Older buildings in Ontario often keep their original mortise locks and wood doors, which can be excellent hardware when serviced. Courtyard buildings from the mid-1900s may also have transoms, glass-panel doors and decorative strike plates. We prefer to repair and rekey period hardware when it's sound and replace only what has worn through, since matching original door preps is slow and parts can be hard to find.
Buildings full of commuters in Ontario empty out by 7 a.m. and fill again after 5 p.m., so the quietest hours for work are mid-morning and early afternoon. We can start at 6:30 a.m. every day for residents who leave late, or work through the middle of the day. Shared doors are repaired before evening so nobody comes home to a door that won't latch.
Example situations
- A midsize building near ONT Field is tired of packages vanishing from the lobby floor. We fit a keypad lever on a small package room, set a staff override cylinder on the building key and explain how to change the code when a courier shares it. Residents collect parcels inside, and the front door works exactly as it always did.
- It's 8:40 on a Wednesday evening and a resident reports that the front door of a twelve-unit building no longer latches, leaving the lobby open to the street. We're working until 11:30 p.m. that night, so a same-evening visit is realistic. A typical outcome is a replacement latch or strike that evening, with finer adjustment and a closer check the next morning.
- For example, a three-story walk-up off Archibald Avenue has a front door that residents hold open with a rubber wedge because the latch drags on its strike. Nobody calls it a security problem until a stranger wanders in. We might realign the strike, adjust the closer's latch speed and fix the drag, so propping the door stops being worth the effort.
- Consider a student-oriented building near Chaffey High School in late summer, when leases turn over and keys disappear. The front-door key is a common type any hardware store can copy. We move the building onto a restricted keyway so copies need the owner's authorization, then reissue keys to each household at move-in against a signed key sheet.
Step by step with Julian's Locksmith
- Tell us about the building. Call (951) 903-3193 and describe the building: number of units and floors, whether corridors are inside or open to the air, what hardware you see on the front door and what prompted the call. Photos of door edges and cylinders, sent by text, help us bring the right parts.
- Confirm who can authorize the work. Proof of authority is quick for most owners. Bring the paperwork you have, or a photo of it if the originals are at the office. We note what we saw on the work order, which also gives you a record of who approved the job and when.
- Walk the building door by door. Expect us to check things you didn't ask about: a stair door that doesn't latch, a gap under an exit, a padlock where a lock belongs. We write them down and rank them by what matters for safety first, then security, then convenience. You decide which to fix.
- Get a written scope, phases and notice. Nothing starts until you approve the scope. If you want to spread the work over several months, we phase it by priority and can quote each phase separately. Anything unexpected we find on site gets requoted before we continue.
- Work the doors in sequence. Residents stay in their homes throughout. If we need to enter a unit, the owner's notice has gone out and either the resident or the manager is present. Tools and parts stay with us, and we clear the hallway after each stretch so the building looks as we found it.
- Test, hand over keys and record it. Before leaving, we test each new key on its door and confirm the old keys no longer work on rekeyed cylinders. You receive labeled keys, a door schedule and a keying record showing which key opens what, with codes on the tags instead of unit numbers.
How we quote the job
- Number and mix of doors and cylinders. A six-unit building with a front door, a laundry room and a back gate is a short visit; a forty-unit building with two stairwells, a garage level and an amenity deck is several. Every cylinder and every door adds time. We count them during the walk-through so the quote reflects your property, not a guess.
- Residents in place and phasing. Batching helps. Doing every unit on one floor in a single visit is faster than returning for each unit separately. If residents can be home at set times or the owner can escort us, the work flows. Missed appointments mean extra trips, and those show up in the final price.
- Electronics and other contractors. Upgrading to fobs or codes means a decision about software. A single keypad needs a code plan, while a fob system needs a management account and someone to add and remove credentials. We'll say honestly when a project is bigger than a hardware swap and suggest how to scope it.
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 Ontario.
Advice before you book
- When a resident reports a lost key, ask where it was lost before deciding anything. A key lost in the laundry room is a different risk from one lost on a trip. If it opens only that unit, rekeying one cylinder is enough; if it opens shared doors too, the front door needs attention.
- Test every stair and rated door by letting it close from wide open. It should pull fully shut and latch without help. If you have to push it, something is wrong with the closer, latch or strike. Never hold a rated door open with a wedge, a rope or a chair, even briefly.
- Walk your building after dark once a season and try every shared door. A front door that looks fine in daylight may hang open a hand's width at night because the closer has slowed down. Note which doors don't latch, which lights are out and which doors swing open when you simply pull.
- Keep a simple key log: who holds which key, when they got it and when they returned it. A spreadsheet is fine. Have each resident sign for keys at move-in and again at move-out, and count them. A missing key at move-out is a good reason to rekey that unit before the next household arrives.
Mistakes to avoid
- Rekeying the units and forgetting the front door. A resident's cylinder gets a new key while the entry door keeps the key that fifty former tenants and three contractors have carried. Start with the shared doors, because they protect everyone, and work inward from there.
- Changing locks without telling residents. A resident who gets home at 10 p.m. to a front door that rejects their key will call the manager, the owner or the police, sometimes all three. Give notice, schedule the key exchange and post a phone number.
- Letting one person hold the only master and the only key record. If that manager leaves, the owner may not know how many copies exist or which doors the master opens. Keep the keying chart with the owner, restrict the master and log who has it.
Getting to Ontario
Ontario is about 25 miles from our San Bernardino base, roughly 33 minutes in light traffic via I-215 North to the I-15 junction at Devore. When you call, you get an arrival estimate based on where the technician is and the traffic at that moment.
Homes and businesses just off I-15 are routine stops for us. Give the suite or unit number and any gate instructions, and say whether the van can park out front or should pull into a side lot.

Frequently asked questions
Do you need to come into residents' apartments?
For shared-door work, no. For rekeying or changing unit locks, yes, which means entry. The owner serves written notice, which California law generally treats as reasonable at 24 hours, and either the resident or the manager is present. If a resident wants to be home, we schedule around them. We never enter a unit on a phone call alone.
Who is responsible for mailbox locks, the building or the Postal Service?
It depends on the lock. The carrier's access to a mailbox bank is controlled by the Postal Service, so ask your local postmaster about that. Tenant compartment locks and the mailroom door are generally the building's responsibility, and we can replace and rekey them. If you aren't sure which lock is which, we'll look at yours and tell you where each one fits.
Can a stair or exit door be locked from the inside?
Not with a key. Doors on the path out of a building must open from the inside without a key or special knowledge, usually with a lever or exit device. A door can stay locked from the outside to keep people from coming in. Chains, padlocks and double-cylinder deadbolts on exits are common violations that we replace, because they can trap residents in an emergency.
Will I get a written quote and a record of the keys?
Yes to both. After a walk-through you get a written scope listing each door, the work and the price, and nothing starts until you approve it. At the end you receive a keying record showing which key opens which door, with codes instead of addresses on the tags. Anything unexpected found on site is requoted before we continue.
What happens if a front door fails when you're closed?
We work every day, 6:30 a.m. to 11:30 p.m. We aren't a 24/7 service. If a door fails outside those hours, secure it as best you can: post a notice, keep a staff member near it if possible and call us at the next opening. Call 911 if anyone is in danger.
Should I replace or rekey the front door lock?
Rekey if the hardware is sound, commercial grade and the door still latches properly. Replace it if the case is cracked, the latch is worn, the lock is residential grade on a busy entry, or the door needs rated or accessible hardware. We show you the worn parts, then price both options side by side so you can compare before approving anything.
How far is Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 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.
