Lock Rekeying in Ontario: Homes, Rentals and Businesses

How this works in Ontario

California shapes rekeying in a few practical ways. Locksmiths here must be licensed by the Bureau of Security and Investigative Services under the Locksmith Act; ours is LCO7891, and you can confirm it at search.dca.ca.gov. Rental law matters too. Landlords must provide working deadbolts on main swinging entry doors, and when a tenant delivers a protective order or qualifying police report, the landlord has 24 hours to change the locks. Changing locks to force a tenant out is illegal, so we always confirm who has the right to authorize the work. Climate plays a part as well. Inland heat, dust pushed by Santa Ana winds and hard sprinkler water all find their way into cylinders, so a rekey in Ontario doubles as a chance to clean pins, replace weak springs and switch to a dry lubricant that won't collect grit. And because so many local homes use the garage as the everyday entrance, the door from the garage into the house deserves the same attention as the front door.

Work included on a typical visit

• Move-in and home purchase rekeying. Moving into a rental rather than buying? A rekey is still worth requesting, but your lease probably requires the landlord's permission and a copy of the new key, and we're glad to coordinate with the property manager directly. Homeowners skip that step: show ID and proof of ownership and we can start re-pinning right away.
• Lost or stolen key rekeying. Not every lost key is an emergency. One key dropped on a trail or at a ballgame with nothing identifying attached is a low-probability threat, and the rekey can wait for a convenient day. Stolen keys, a stolen car with a house key inside, or a bag that held your ID call for same-day action instead.
• Rental turnover rekeying for landlords. California expects landlords to provide working deadbolts on main swinging entry doors, and turnover is the natural time to check them. During a rental rekey we also look at the strike, the bolt's throw and the window latches, then tell you what falls short before the new tenant arrives. You'll get key counts in writing for your files.
• Rekey-or-replace lock assessment. Sometimes the right answer sits in between: keep the handle set but replace only the cylinder, or keep the deadbolt and swap a failing knob for a lever. Mixed brands can often be brought onto one keyway so everything runs on a single key. A good assessment opens those middle options instead of forcing an all-or-nothing choice.
• Smart locks, keypads and garage openers. Bought a house with a Wi-Fi lock? The previous owner's account may still control it, and a factory reset is the clean start; most models have a reset procedure near the battery compartment. Retrofit locks such as August keep your original deadbolt cylinder on the outside, so that cylinder still needs rekeying like any other.

Local factors in Ontario

Large hotels run on card systems, but smaller lodging, event venues and attractions still depend on keys for storage rooms, housekeeping closets, maintenance shops and back-of-house doors. Rekeying when managers or seasonal staff change keeps those areas closed to former employees. A master system with restricted keys suits these operations, since staff turnover is constant and keys go missing often, and it limits each rekey to the doors truly affected.

Warehouses and distribution buildings mix commercial cylinders with heavy padlocks on roll-up doors, yard gates and containers. When a building changes tenants or a shift lead leaves, those padlocks are the locks most often forgotten in a rekey. We bring shrouded rekeyable padlocks keyed into the same system as the office doors, so one key structure runs from the front desk to the dock, and your key log shows exactly who can open the yard.

Commuters with long drives tend to lose keys far from home: a park-and-ride, a gym near the office, a train platform. When that happens, the question is whether anything with your address went with them. If so, call before you start home so we can plan the rekey for that evening; we work until 11:30 p.m. every day. If not, book an early visit before you leave for work, since we start at 6:30 a.m.

Situations this covers

A landlord with a duplex near Westwind Park and a rental house a few blocks away asks what to do with a set of aging locks. We find 20-year-old Schlage deadbolts that turn smoothly, so those are rekeyed, but the knobs under them are worn and loose, so those are replaced. The landlord leaves with one new key for each unit and a note listing which locks were rekeyed and which were swapped.

• An executor settling a parent's estate realizes the neighbor, two former caregivers and a cousin all held keys. In a situation like this, we'd confirm authority with the court-issued letters, rekey every exterior door and the detached garage, free up a back door lock that hadn't turned in years, and leave keys with the executor plus one for the listing agent's lockbox.
• Consider a short-term rental owner whose keypad deadbolt makes guest check-ins easy, but whose physical backup key has been copied for three cleaners and a handyman over two years. We'd rekey that backup cylinder, rotate the owner and programming codes, delete stale guest codes, and leave two keys: one with the owner and one in a lockbox only the current cleaner can open.
• For example, a buyer closes on a 1970s ranch house with a Schlage front knob, a Kwikset deadbolt someone added later, an off-brand lock on the garage door and a slider handle with no working key. We'd rekey the Schlage knob, replace the odd-brand deadbolt and garage lock with Schlage hardware so one key runs everything, and fit a keyed slider lock the new owner can actually use.

Step by step with Julian's Locksmith

1. Tell us why you're rekeying. When you call (951) 903-3193, describe the situation in a sentence or two and give us a rough count of doors and brands if you know them. Kwikset, Schlage, Medeco or an unlabeled import each call for different parts, and that short conversation lets us arrive in Ontario with the right pins and blanks.
2. Show who authorized the work. Executors, trustees and agents acting under a power of attorney bring the document that gives them authority, along with photo ID. We don't need the whole file, only enough to show the property is yours to secure. Verifying authority is how a licensed locksmith avoids being used against the rightful owner.
3. Walk every door and count cylinders. We walk the property with you and list every keyed cylinder: entry knobs and levers, deadbolts, the garage service door, the house-to-garage door, the slider, side gate, shed, mailbox and padlocks. Doors people forget are often the ones a former key holder would choose, so nothing gets skipped on assumption.
4. Decide rekey or replace, lock by lock. Most locks pass and get rekeyed. The ones that don't usually make it obvious: a deadbolt that needs the door shoved before it'll lock, a knob loose on its rose, corrosion on the latch, or a light-duty entry set on a main door. Those get a replacement quote, and you decide whether to act now or later.
5. Re-pin, test and cut keys. Each cylinder comes out, gets new key pins matched to the new bitting, and goes back in. Then we test every key in every lock with the door both open and closed, because a deadbolt that turns freely on the bench can still bind against a misaligned strike once it's back in the door.
6. Reset codes, remotes and records. Before we leave, we go through the electronic side with you: keypad user codes, smart lock app users, garage remotes and keypads, gate transmitters. Lock rekeying in Ontario only finishes the job when those are cleared too, and we'll show you how if you'd rather handle them yourself later.

What affects the cost

• Brand, keyway and lock type. Lock type affects labor. A standard deadbolt cylinder comes out quickly, while a storefront mortise cylinder, a lever with a hidden retainer or a smart lock with a tightly packed backup cylinder takes longer to disassemble. Kwikset SmartKey resets are fast when a working key exists and slower when one doesn't.
• Lock condition. Locks that haven't turned in years, common in vacant or inherited homes, can be seized solid. Freeing them without damage takes patience and penetrating cleaner, and now and then a lock can't be saved. We'll tell you before spending time on a lock that's probably headed for replacement regardless.
• Keys and add-ons. Key tags, colored key heads for different doors and stamped key numbers for businesses cost little and make tracking easier. None of them are required. We mention them because a rekey's value depends on keeping track of the new keys afterward, and small tools make that much easier to do.

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.

Practical tips before you call

• Tell us about hidden spare keys, old realtor lockboxes or keys handed to neighbors. A key under the doormat or inside a fake rock works just as well for a stranger as for you. After the rekey, leave your spare with someone you trust rather than outside.
• Walk your property before calling and count every keyhole: front knob and deadbolt, back door, garage service door, house-to-garage door, slider handle, side gate, shed, mailbox and any padlocks. That list makes a lock rekeying quote accurate and keeps a forgotten door from staying on the old key for years.
• Condo and townhome owners should check with the HOA before touching anything connected to common areas. Your unit door is normally yours, but lobby doors, pool gates and parking access often run on an association key system that only the HOA's manager or vendor can change.
• Before assuming you need new hardware for one-key convenience, ask what it would take. Kwikset and Schlage use different keyways, yet the fix may be a single cylinder or lock replacement while the rest are simply re-pinned. A short conversation often turns a full replacement plan into a much smaller job.

Mistakes to avoid

• Changing locks on someone who still has a legal right to be there. In California a landlord can't lock out a tenant to force a move, and one spouse or co-tenant generally can't lock out another without a court order. Get legal advice first; a licensed locksmith will ask about authority.
• Rekeying only the front door. Former owners, tenants and staff rarely limit themselves to the front; they use the garage service door, the house-to-garage door or the back gate. A partial rekey leaves the old key working on exactly the doors you're least likely to watch.
• Paying to rekey a lock that's already failing. If the key sticks, the plug wobbles or the deadbolt only throws when you push on the door, the hardware is near the end of its life. Re-pinning it buys little time; replacing it once costs less overall.

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.

If you're close to Mission Boulevard, tell us which exit or cross street you're nearest. It trims the last mile and keeps the van from circling a block that looks right on the map but isn't.
