Rental Locks Handled: Ontario Locksmith for Landlord Work
Short answer: A locksmith for landlord work handles the lock side of owning rentals: rekeying between tenancies, repairing sticky deadbolts, swapping worn hardware, cutting labeled owner keys and keeping records. Julian's Locksmith drives to your rental anywhere in Ontario, confirms you own or manage it, quotes before starting and holds California license LCO7891. Call (951) 903-3193 and tell us how many doors you have.

Open a long-time landlord's truck console and you'll often find a ring of thirty or forty keys, half of them unlabeled, none of them certain. That ring is the hidden cost of owning rentals in Ontario. Each property got keyed whenever a lock failed, with whatever brand was on sale that week, so no two doors agree. We help landlords reverse that. Choosing one brand and one keyway per property, keying front, back and garage doors alike, and keeping a coded owner set shrinks the ring to a handful of keys. Replacing a lost key stops being a guessing game. The work is done door by door, tested, and written down for next time.
What to know first in Ontario
Opening or rekeying a rental is a security-sensitive job, so we verify authority first, and as a landlord you should want us to. For an owner, the simplest proof is a photo ID matching the name on a property tax bill, deed, closing statement or the lease you signed as landlord. If a property manager, relative or trustee is calling for you, a written authorization or management agreement does the same job. California's Locksmith Act, administered by the Bureau of Security and Investigative Services, is the legal backdrop for that caution, and our license, LCO7891, can be checked at search.dca.ca.gov. If you can't be there, a tenant, neighbor or agent you name can meet us, and we confirm the authorization with you by phone before work begins. Occupied units add one rule of our own: the tenant should know we're coming. Photos before and after, a written summary and an emailed invoice mean the file is complete even if you never set foot on the property.
How we can help in Ontario
- Rekey-or-replace triage, door by door. We walk the property with you, or with whoever is on site, and test every lock for the problems that decide the question: wobble, drag, a latch that won't fully retract, worn pins that make keys stick. Sound hardware gets rekeyed. Failing hardware gets a replacement quote. You see each door's verdict and its price separately.
- One key system per property. We pin every cylinder at a property to the same cut and the same keyway, so one blank covers it all. If the existing locks come from three brands, we may swap a cylinder or two so the whole house can share a key. The result is a lighter ring for your tenant and simpler records for you.
- Rekeying a rental you just bought, inherited or took back. Taking a house back from a former manager or a tenant who left means getting a clean slate quickly. We rekey, replace anything the previous occupant damaged or modified, and give you the keys in a labeled set. Whether or not the old manager returns every key, rekeying makes the question irrelevant.
- Owner key sets, spares and labeled copies. Copying is where key control leaks. We duplicate only for people you've approved, mark each batch in your record, and can cut keys on site during a rekey, so a tenant never has to run to a hardware-store kiosk where copies vanish into nowhere.
- Owner-only spaces: utility closets, storage and shut-offs. Detached garages, sheds and storage rooms often get left with an old padlock and a mystery key. We replace them with a keyed cylinder on a separate key, so you decide who holds access, and whatever you keep inside stays yours between tenancies.
How Ontario shapes the job
Inland summers in Ontario are hard on rental hardware. West-facing doors bake, finishes fade, wood swells and keypad batteries die early. Landlords here do well to schedule a lock check each spring: lubricate cylinders with dry graphite or PTFE, adjust the strike on swollen doors, and replace batteries before July. A tenant locked out on a triple-digit afternoon is both a safety issue and a service call a little maintenance would have prevented.
Newer tract homes in Ontario usually arrive with builder-grade hardware keyed to a construction key or a developer's bulk order. For a landlord, step one is rekeying away from any key the builder, agents or earlier owners might still hold. Much of this hardware is sound and needs only new pins. Standard-bore doors also accept most smart deadbolts without new drilling, so you can add keypads later if you like the idea. Keep one lock sheet per house.
Tenants who commute long distances from Ontario leave before dawn and return after dark, so a lockout rarely happens at a convenient hour. Landlords with commuter tenants do best with a pre-arranged plan: a spare with a trusted neighbor, a keypad deadbolt, or our number saved in the tenant's phone. We start at 6:30 a.m. and work until 11:30 p.m. every day, and we're closed overnight, so plan for the gap.
Common situations
- Say you've inherited a bungalow near Graber Olive House where a tenant has lived for eleven years. The deadbolt is original, and nobody knows who has keys. After written notice and the tenant's agreement on a time, we rekey the whole house, adjust a sagging back door, and give both of you fresh keys. Not one stranger's key still works.
- Three leases at a small apartment building end the same weekend. The landlord calls on Wednesday, we book a Sunday start at 6:30 a.m., and the three units are rekeyed and tagged before the cleaners need them. Because she gave notice early, the make-ready crew arrives Monday with nothing left to wait on and a set of tagged keys already on the counter.
- A homeowner finishes an ADU behind her house in Ontario and plans to rent it. The main house key must not open it, and the new tenant must not reach the garage. We key the ADU to its own set, install a deadbolt on the entry door and secure the windows as Civil Code section 1941.3 expects, and label each building's owner key separately.
- A duplex off Haven Avenue has a shared exterior closet holding the water shut-off, the irrigation controller and the owner's tools, and both tenants' keys open it. We rekey the closet to an owner-only key and give each unit its own key. The tenants keep everything the lease promises, and the owner's equipment stays the owner's.
How the visit works
- Tell us about the property and the problem. Call (951) 903-3193 or send a message with the rental's address, the number of doors, gates and mailboxes, and what's going on. Mention whether it's occupied. If you have photos of the lock hardware, send those too; they help us bring the right parts.
- Confirm you're authorized. If you're not the one at the property, tell us who is. Tenants, agents and neighbors can meet us on site after we confirm the authorization with you directly. We note who authorized the work and when.
- Inventory the locks and decide rekey or replace. On arrival we test every lock, including the ones you forgot to mention, such as the garage side door, the gate and the mailbox. Each gets a verdict: rekey, replace or adjust. You see the whole picture before we approve anything.
- Get an itemized quote and approve it. The quote lists each door and each task, whether rekey, replace or repair, plus any travel details. Nothing starts until you say yes, by phone, text or in person. You choose which items to approve.
- Do the work, test it and sign off. Where tenants are home, we keep the visit tidy and brief, then check that they received the right number of keys. You get photos of any hardware we replaced, and the old parts if you'd like them.
- Keep the keys and records. Before we leave, we hand over the keys one by one, count them aloud and write the count in your record. Months later, that count tells you whether a missing key is a real problem or just a bookkeeping gap.
What affects the cost
- Rekey or replace, door by door. Rekeying keeps the existing finish and latch, which is why it tends to be cheaper. But a rekey on a loose, worn lock is money spent on something you'll replace soon. For doubtful doors our quote shows both options so you can weigh lifespan against upfront cost.
- How many cylinders the property has. People forget how many keyed points a property has: the front, the back, the side gate, the shed, the mailbox, the garage entry, the water-heater closet. We list them all in the quote. Including them in one visit costs less than returning for the one you forgot.
- Occupied or vacant, and who provides access. If a tenant must be home, line up the time with them before you call us. A visit where nobody answers the door is a wasted trip, and that time has to be accounted for somewhere. Written notice to the tenant and a confirmed window prevent 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.
Mistakes to avoid
- Letting a contractor keep a key after the job ends. The painter finishes, the key stays in his truck, and you never think about it again. Collect keys against a signed receipt, or use temporary codes and a lockbox so nothing needs collecting at all.
- Ordering locks online without measuring. A door with a 2-3/4 inch backset fitted with a lock built for 2-3/8, or a thinner door than the hardware expects, means returns, chiseling and ugly gaps. Measure thickness, backset and bore, or send us photos before you buy.
- Rekeying hardware that's failing. A rekey cannot fix a loose deadbolt, a latch that drags or a door that has dropped on its hinges. You pay for new keys, and the next tenant calls with the same complaint. Diagnose the door and the lock before deciding on the work.
What to do before we arrive
- Keep one boxed replacement deadbolt of your standard model on a shelf. When a tenant's lock fails on a day we're booked or closed, a handy relative or maintenance person can swap it in, and we can rekey it to match your system at the next visit.
- Replace keypad deadbolt batteries on the same date you test smoke alarms, and write that date inside a cabinet door. Heat shortens battery life, and a dead keypad at a rental with a full-time tenant means a lockout call that a calendar reminder would have prevented.
- Ask your locksmith for the key code after any rekey and store it away from the keys themselves. Many locks let a locksmith cut a new key from a code once ownership is verified. It keeps a lost key from turning into a full re-pinning of the property.
- Avoid giving contractors the same key your tenant carries. Use a lockbox, a keypad code or a one-visit meeting at the door. A copy of a tenant key in a handyman's glove box is still a working key to that home long after the repair is finished.

Plain version of the schedule: every day, 6:30 a.m.-11:30 p.m. Outside those hours nobody is out on the road, and we'd rather you know that now than discover it in the middle of a lockout. For an overnight safety problem, such as a door that won't latch after a break-in, call the police first.
Safes get the same scrutiny. Before drilling or manipulating one, we need reason to believe it's yours: a purchase record, the fact that it sits in your home or business, or estate paperwork if you inherited it. A safe exists to keep people out, so proof of ownership isn't optional.
Locked out in Ontario?
Call (951) 903-3193 with the address and what's locked. You'll get an arrival estimate and a quote before anyone heads out, and when we arrive we'll ask for ID that ties you to the property. If a child or pet is shut inside a hot car or building, call 911 first.
Frequently asked questions
How far ahead should I book before a move-in date?
As soon as you have a firm move-out or move-in date. We can't promise a specific day to everyone, but early notice lets us fit your doors into a route and gives us time to order any hardware that has to be replaced. For a simple rekey, a few days' notice often works; for several units, replacement hardware or a master key system, give us more.
How do I give a contractor access to a vacant rental?
The cleanest method is a keypad deadbolt with temporary codes, because each worker gets a code for a set period and it's deleted afterward. A lockbox is a good second choice for one-time visits. If you hand out physical keys, keep a log, collect them against a signed receipt and plan a final rekey before the new tenant moves in. Never hand a contractor the key your tenant carries.
I live out of state. How can I authorize work on a rental?
A locksmith for landlord clients who live elsewhere starts with a call. Then email a copy of your ID and a document showing ownership, such as a tax bill, deed or closing statement. Tell us who will be at the property, whether a tenant, agent or neighbor, and we confirm the authorization with you by phone before starting. We photograph the work and email an itemized invoice, so you have a complete record without being there.
Do you also work on commercial space in a mixed-use building I own?
Yes. Julian's Locksmith handles residential, commercial and automotive work, so a storefront or office under apartments, or a small shop behind a house, is not a problem. Commercial doors often use different hardware, such as storefront cylinders and exit devices, and a business tenant may want its own key control. We treat each space as its own system and price it separately.
How many keys should I keep, and how many should a tenant get?
Keep one full owner set where you live and a second stored separately, such as with a trusted relative or property manager. Tenants should receive the number written in the lease, often one per adult occupant, plus any garage, gate or mailbox keys. We cut the exact count during the rekey and note it in your record, so the number you issued matches the number that exists.
I inherited a rental. What should I do about the locks first?
Confirm who has legal authority, usually through probate or trust paperwork, and bring it with photo ID when you call. Your attorney can tell you exactly which documents apply. Then rekey every exterior lock, because you can't know who was handed keys over the years. After that, check deadbolts and window latches, label one owner set and write down what's installed. If a tenant lives there, give written notice before our visit.
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.
