Fast, Reliable Lock Installation & Rekey Across Ontario
Lock installation and rekeying in Ontario, CA typically costs $89-$280 for residential work, with same-day scheduling available throughout the city. Our technicians carry Schlage, Kwikset, and Medeco hardware on every truck, so most jobs finish in a single visit without waiting on parts.
We’ve been driving to Ontario since before the Ontario Ranch development broke ground. We know the difference between a 1962 ranch off Euclid Avenue in ZIP 91762 and a brand-new build off Haven Avenue in 91761, and we know the locks that fail on each. The Santa Ana winds that sweep through the I-10 corridor don’t just rattle windows; they pack grit into old cylinder housings and dry out the lubricant that keeps tumblers moving freely. When your key starts sticking or your deadbolt grinds, that’s usually why. Call us at (877) 664-8139 and we’ll quote a flat price before we leave the shop.
Why Strongbox Lock & Safe Co. Is Ontario’s Preferred Lock Installation & Rekey Company
Ontario residents have called us for over 42 years because we show up when we say we will and we stand behind the work. Our 90-Day Done Right Promise means if a lock we installed or rekeyed doesn’t operate smoothly, we come back. No paperwork to file, no argument.
We’re not the $19-ad locksmith who quotes one price on the phone and invoices another at the door. We give you the full price before the truck rolls. Our technicians are background-checked, uniformed, and present company ID at every Ontario door. A live person answers our phones 24/7, including holidays, because a lock problem doesn’t wait for business hours.
We understand Ontario’s split personality: the established neighborhoods north of the 10 Freeway where original 1950s-1970s hardware is finally giving out, and the explosive growth south of the airport where new homeowners want something better than what the builder installed. Both call us. Both get the same flat-price, written-guarantee treatment.
Our Lock Installation & Rekey Services in Ontario
Smart Lock Installation
Older Ontario homes in ZIPs 91762 and 91764 weren’t built for Wi-Fi deadbolts. Door preps from the 1960s often lack the clean 2-1/8″ bore and proper backset that modern smart locks require. We retrofit those openings properly, not with adapter plates that flex and fail. For Ontario Ranch buyers in 91761, smart lock installation is usually straightforward on new doors, but we still verify the door thickness and edge bore alignment before we quote. A Schlage Encode or Yale Assure installed wrong will chew through batteries and leave you punching codes in the dark. We do it once, done right.
Electronic Lock & Keyless Entry
Keyless entry systems suit Ontario’s rental market and multi-generational households, where tracking physical keys becomes its own job. We install standalone electronic locks and hardwired access control for commercial clients. The distribution centers clustered around Ontario International Airport cycle through workers constantly; a keypad or card reader that logs entry times beats rekeying every quarter. For residential customers near Ontario Mills or the Colony District, a simple electronic deadbolt with a backup key override provides convenience without complexity. We stock replacement parts locally, so a failed keypad doesn’t mean a week of waiting.
Biometric Lock Installation
Biometric locks fingerprint-scan entry and work well for Ontario home offices, gun safes, and small commercial spaces with limited user counts. The dry heat here affects optical sensors less than capacitive ones; we match the hardware to the environment. Most biometric installations in Ontario run $280-$450 depending on door prep and whether we’re integrating with an existing system. We don’t recommend biometric as the sole entry method for high-traffic doors; a fingerprint reader handling 200 scans daily in a warehouse corridor will fail faster than one on a residential front door. We tell you that upfront.
Key Duplication
We duplicate standard keys on-site in Ontario. High-security keys like Medeco, Mul-T-Lock, and Abloy require authorization and specialized equipment; we carry that too. If your Ontario office runs a restricted keyway, we need the key control card or sign-off from the registered owner. No exceptions. That policy protects your key system from unauthorized duplication, which is the entire point of buying high-security hardware in the first place.

Trusted Brands We Service in Ontario
We install and service Schlage, Kwikset, Medeco, Yale, Mul-T-Lock, Abloy, Baldwin, and Sargent. For Ontario customers, this means we don’t substitute what’s on the truck for what your door actually needs. A Schlage B60N deadbolt fits the reinforced strike plate on an older Ontario home better than a lightweight alternative. A Medeco Maxum makes sense for a warehouse office with high-value inventory. We stock common cylinders and locksets at our local warehouse, so most Ontario rekeys and replacements finish same-day without ordering delays.
Common Lock Installation & Rekey Problems We See in Ontario Homes
- Seized original deadbolts in north/central Ontario. The 1950s-1970s ranch homes in ZIPs 91762 and 91764 often carry original Schlage or Kwikset hardware that’s never been serviced. Santa Ana winds carry fine particulates from nearby logistics yards; combined with summer heat exceeding 105°F, this dries cylinder lubricant and packs grit into tumbler stacks. The key sticks, then jams, then won’t turn at all.
- Builder-grade failures in Ontario Ranch. New-construction homes in ZIP 91761 ship with entry-level Kwikset SmartKey deadbolts installed fast, not installed well. Loose tolerances and shortcut prep work mean keys that work on closing day may not work six months later. We rekey or replace these with proper hardware before the first failure.
- Commercial master key systems fouled by warehouse dust. Ontario’s distribution corridor generates particulate loads that residential locksmiths rarely encounter. Master key cores in forklift traffic areas bind or shear when grit infiltrates the keyway. Quarterly maintenance contracts prevent the emergency rekey at midnight.
- Smart lock battery drain from temperature swings. Ontario’s inland basin sees 40°F temperature swings in a single day during fall and spring. Cheap electronic locks mounted on south-facing doors cook their battery contacts. We specify hardware rated for the temperature range and install with proper weather sealing.

FAQs - Lock Installation & Rekey in Ontario
Hard turning usually means grit infiltration and dried lubricant, not worn pins. We can often restore operation with cleaning, lubrication, and rekeying for $89-$140 per cylinder. If the bolt mechanism itself is corroded or the faceplate is cracked from decades of use, replacement makes more sense. We inspect before we quote and tell you honestly which path saves money long-term. Call (877) 664-8139 for a free look.
Yes. You don’t know who held keys during construction: contractors, inspectors, cleaners, real estate agents. Rekeying runs $89-$140 and takes under an hour. Many Ontario Ranch buyers also upgrade to a Schlage B60N or smart lock while we’re there, since builder-grade hardware is the cheapest item that met code, not the lock you’d choose yourself. We can quote both options on the phone.
Quarterly rekeying or access credential updates are standard for Ontario distribution centers with high turnover. Some clients with extreme churn rekey monthly. We offer contract pricing for scheduled service, which costs less per visit than emergency callouts. The density of warehouse turnover in Ontario’s logistics corridor makes this a routine service here; it’s simply not needed at this frequency in neighboring Chino or Upland. Call to discuss volume pricing.
Yes, but it requires proper retrofitting, not forcing a standard lock into an irregular opening. We bore clean 2-1/8″ holes, set correct backsets, and reinforce strike plates on older Ontario doors. The work runs $180-$340 depending on prep complexity. We’ve retrofitted homes from the 1950s ranch tracts near Euclid Avenue and Holt Boulevard with clean, concealed hardware that looks original. A site visit lets us quote accurately.
Yes, with proper authorization. Mul-T-Lock keys require the key control card or registered owner sign-off; we carry the duplication equipment on our Ontario service trucks. Standard high-security duplicates run $45-$65 per key. Without authorization, we cannot cut the key; that’s the security feature you paid for. Bring the control card or call us to verify ownership protocols. We can meet you at your Ontario office or our shop.
We’re here when you need us. A live person answers every call, 24/7, including nights, weekends, and holidays. No voicemail trees. No callback queues. Call (877) 664-8139 for a free estimate on lock installation, rekeying, or any security hardware question. The price we quote is the price you pay. Done right, and backed in writing.
