Lock Help for Ontario Landlords, Mid-Lease and After Eviction
Short answer: Good key control keeps a landlord's job simpler. Keep a labeled copy of every unit key, record key codes, consider a restricted keyway so tenants can't copy keys at a kiosk, and give each property its own key. Julian's Locksmith can set that up across your Ontario rentals and keep the records you'll want later.

Eviction cases end with a practical moment: the sheriff's deputy arrives, confirms the unit is empty or removes the occupants, and hands possession back to you. What happens in the next hour matters. Any key the former tenant kept still works until the locks are changed, and garage remotes, gate fobs and mailbox keys are just as live. Julian's Locksmith can meet you at your Ontario property on lockout day, rekey or replace every exterior lock as soon as possession is returned, and give you a fresh set of keys before you leave.
How this works in Ontario
Most landlord lock calls aren't dramatic. A deadbolt starts sticking, a key breaks in the knob, a tenant loses a set, or a roommate moves out and the remaining tenant wants new keys. Civil Code §1941.3 makes you responsible for keeping the deadbolt and window locks operable once you know they've failed, so a tenant's written report starts the clock on a reasonable repair. Tenant-installed locks are their own category. Many leases require written permission before a tenant changes or adds a lock, and require a key or code for the landlord. If a tenant swaps in a smart lock without asking, the usual fix is a polite written request for a key or code first, then a scheduled visit with notice to restore your access. We can reinstall the original hardware keyed to your system and hand the tenant's device back in its box. Lost keys and roommate changes are often billed to the tenant under the lease, but that's your lease's call, not ours. What we add is a written invoice describing exactly what was done, which helps if the cost ends up in a deposit discussion.
Work included on a typical visit
- Protected-tenant lock changes. When a tenant gives you a protective order or police report with a written request for new locks, you have 24 hours. Call us as soon as it arrives. We rekey every entry cylinder to a new key, give the tenant their keys and you yours, and keep the visit discreet.
- Post-eviction lock changes. Former tenants sometimes leave damage behind: a broken knob, a keyway jammed with glue, a missing strike. We repair or replace those on the same visit when the parts are on the van, so the unit can be secured that day and shown to new applicants soon after.
- Restoring access after a tenant changes locks. Some tenants change locks for legitimate reasons, such as a safety worry they never mentioned or a lost key they were embarrassed to report. A calm conversation usually solves it. We can rekey whatever is on the door to a key both of you hold, restoring your access without a fight.
- Key control and restricted keyways. We set up a simple key system: each property on its own key, every key stamped with a code, owner copies stored off site, and a log of who holds what. When a tenant leaves, you compare the log with the returned keys and know right away whether a rekey is urgent.
- Securing an abandoned or vacated unit. If a tenant has passed away, the unit may hold belongings the estate needs to handle. Once you've confirmed the proper steps with the estate or your attorney, we can secure the unit so only you hold keys, then open it later for the executor or family at a time you arrange.
How Ontario shapes the job
Older rentals in Ontario often have hardware that predates the tenant, and sometimes the previous owner: mortise locks, worn knobs, deadbolts that barely throw. When a tenant reports a failing lock in an older house, the cause is often the door or frame rather than the lock. We diagnose before replacing, which keeps repair costs reasonable on houses where every door is slightly different.
Commuter tenants leave early and get home late, so their lockouts tend to happen at dawn or late in the evening. Our hours run 6:30 a.m. to 11:30 p.m. every day of the week, weekends included, which covers many of those calls. A landlord lockout policy that tells tenants to call us directly saves you from being the early-morning key runner.
Landlords with small apartment buildings in Ontario juggle more tenants and more shared doors. Lockouts, protected-tenant requests and roommate changes come up more often, and each one touches the building's key system. Keeping a key log for every unit, using a restricted keyway for common entries, and having a locksmith who knows the building's keying chart turns those calls into routine work rather than emergencies.
Situations this covers
- Imagine a tenant who reports in writing that the back door deadbolt won't turn. The landlord gives notice for the next afternoon. We find the door has dropped on its hinges, pushing the bolt against the strike plate. Longer hinge screws, a strike adjustment and a test with the door closed solve it, and the landlord's invoice records the fix and the date.
- For example, a landlord owns four small rentals and carries a ring of 23 keys, some unlabeled. We'd standardize every property on one restricted keyway, give each property its own key, stamp each with a code, and leave a key log. The landlord's ring drops to four keys, and no tenant can copy one at a hardware kiosk.
- Picture three roommates sharing a house near Ontario Town Square. One moves out on bad terms and doesn't return his key. The landlord and the two remaining tenants sign a new lease, and the landlord authorizes a rekey. We re-pin the front deadbolt, knob and side door, cut four keys, and the old roommate's key stops working that afternoon.
- Imagine a tenant who lost her keys at a concert and asks the landlord to rekey. The landlord authorizes the work, and the lease says lost keys are the tenant's cost. We rekey the entry locks and the mailbox, cut new keys, and give the tenant the invoice directly, with a copy to the landlord for the property file.
Step by step with Julian's Locksmith
- Tell us who's calling and why. If a tenant is calling, have the landlord's name and number ready. If you're the landlord calling for a tenant, tell us how they'll prove residency. Sorting out authority on the phone means nobody stands at the door waiting while we make calls.
- Confirm authority. When authority is unclear, we pause. A former spouse who's still on the lease, a relative with no paperwork, a manager whose contract ended: each needs sorting out first. It's slower in the moment and much faster than undoing a lock change that shouldn't have happened.
- Notice and scheduling. Deadline jobs get scheduled first. A protected tenant's 24-hour window or a sheriff lockout on a fixed date takes priority over routine maintenance. Tell us the deadline at the start of the call and we'll tell you honestly whether our schedule can meet it.
- Quote and agree who pays. We quote before work starts and tell you what's included. If the lease makes the tenant responsible, such as for a lockout or lost keys, we can quote the tenant directly with your agreement. Either way, nobody gets a surprise bill at the end, and the invoice names who approved the work.
- Do the work. If we see something you should know about, such as a cracked jamb, a window latch that has failed or a lock a tenant has tampered with, we mention it and photograph it. You decide what to do next; we simply make sure you know.
- Keys, records and follow-up. We'll note the key code for each new combination so spare keys can be cut later without another rekey. Update your key log, store the owner copies off site, and you're ready for the next call from that property. If a tenant later asks for a spare, it can be cut from the code.
Pricing factors
- Rekey, repair or replace. Rekeying sound hardware is usually the least expensive way to change who has access. Repairing a sticking deadbolt is often cheaper still. Replacing hardware costs more because you're buying new locks, but it's the right answer when a tenant has damaged them or they're worn out.
- Key system and keyway. If your properties are already on one restricted system, adding new cylinders and keys is straightforward. Starting one from scratch costs more up front. We'll help you phase it in, perhaps beginning with the property that turns over most often.
- Property condition and access. A door that's out of alignment, a split jamb or a missing strike adds work beyond the lock itself. We'll point out what we see before we quote, and if the problem needs a carpenter rather than a locksmith, we'll say so instead of padding the job.

Practical tips before you call
- After any rekey, collect the old keys if you can and destroy them, or at least mark them clearly. A drawer of unlabeled old keys becomes confusing within a year, and a stray key from a previous combination can mislead someone during an urgent call.
- Tell tenants we're closed between 11:30 p.m. and 6:30 a.m., so your lockout plan needs to cover that window. An owner copy kept nearby, a trusted neighbor or a backup plan for those hours keeps a forgotten key from turning into an all-day ordeal.
- On sheriff lockout day, change more than the front door. Rekey every exterior cylinder, the mailbox and any gate locks, and clear garage remotes and keypad codes. Former tenants often keep a garage remote even after handing over every key they were asked for.
- If tenant key copying worries you, move to a restricted keyway rather than relying on stamped warnings. Patented key blanks can only be cut through authorized channels, which gives you an accurate count of the keys in circulation at every move-out.
Mistakes to avoid
- Ignoring a tenant's report that a deadbolt won't lock. Once you've been told, the clock starts on a reasonable repair. If a break-in happens through that door while the report sat unanswered, the delay is going to be very hard to explain.
- Clearing out a unit you think is abandoned before completing the required notice steps. Belongings and possession have specific rules in California, and acting early can turn a vacancy into a lawsuit. Secure the property, document it with photos, and follow the process first.
- Sending a tenant to meet a locksmith without telling anyone who's authorized. The tenant arrives without proof of residence, you're unreachable, and the locksmith can't proceed. Give tenants a clear lockout process and keep your phone handy when you know a lock job is underway.
Reaching 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.
Once the evening commute thins out on Mission Boulevard, drive times usually shrink. That makes an evening call before closing a practical option for non-urgent jobs that you couldn't fit into the workday.

Frequently asked questions
Can a landlord change the locks on a tenant in California?
Not to force them out. Civil Code §789.3 prohibits landlords from changing locks, removing doors or windows, or cutting utilities to make a tenant leave, and it carries penalties for each day the violation continues. The lawful path is an unlawful detainer case. After the sheriff executes the writ and returns possession, you can change the locks, and that's when we'd meet you at the property.
What about belongings a tenant leaves behind?
California has a specific notice procedure for a former tenant's personal property, so don't simply haul everything away. Photograph what's left, follow the notice process, and store items as required. We handle the locks: once you have legal possession, we can rekey so the unit stays secure while the belongings question is resolved. A landlord-tenant attorney can guide the details.
How do I stop tenants from copying keys?
Use a restricted or patented keyway, such as Medeco or Mul-T-Lock, where blanks are only available through authorized dealers. Tenants can't get copies at a hardware store or kiosk, and extra keys come through you. 'Do Not Duplicate' stamps help a little but aren't reliable in practice. Rekeying at every turnover is the other half of key control.
What must I do when a tenant gives me a protective order and asks for new locks?
Change the locks within 24 hours of receiving the tenant's written request in certain situations involving a protective order or similar documentation, under Civil Code §1941.5 or §1941.6. Rekeying the existing hardware is normally the quickest way. Call us as soon as the request arrives, tell us how many entry doors the unit has, and keep the paperwork confidential.
Will you open a unit for my tenant if I can't be reached?
Yes, if the tenant can prove they live there. We need photo ID plus something tying them to the address, such as the lease or a recent utility bill in their name. A call from you speeds things up, but we don't strictly need it when the tenant's documents line up. If they don't, we wait until we can confirm.
Will you change the locks on an occupied unit without the tenant knowing?
No. Apart from a protected tenant's own request, lock changes on an occupied unit happen with notice, and the tenant receives working keys. If the goal is to keep a tenant out, that's an illegal lockout in California and we won't take part. If the tenant has moved out and returned possession, or the sheriff has returned it to you, the situation is different.
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.
