Fast, Reliable Lock Installation & Rekey Across Ontario
Lock installation and rekeying in Ontario, CA typically costs $45-$95 per cylinder for a standard rekey and $120-$280 for a new deadbolt or entry lock installed, with the full price quoted in writing before anyone is dispatched. That price is the price on the invoice. We answer the phone live, 24/7, and our crews serve Ontario homes and commercial buildings along the Milliken and Vineyard Avenue corridors daily. Call (331) 310-8471 and you’ll get a firm number, not a range that shifts when the van pulls up.
Why Novak Lock & Security Is Ontario’s Preferred Lock Installation & Rekey Company
Since 2002, we’ve installed and serviced over 60,000 locks, keys, and systems, and every one of those jobs started with a written price and ended with a documented photo record. That’s not a slogan. It’s Haven Standard Clause 1: the price on the phone is the price on the invoice. Our technicians are background-checked, uniformed, and they work to the same documentation framework across all ten Haven brands.
Ontario is a different locksmith market than Upland or Claremont, and we know it. A technician who only does residential rekeys can’t help the warehouse manager off Vineyard Avenue who needs a 40-cylinder master-key system rekeyed before a terminated employee’s access expires. We handle both. The same crew that rekeys a 1960s tract home near the Model Colony Historic District can program a keyless entry system at a cross-dock facility by the airport the same afternoon. Daniel Novak built Novak Lock & Security on that range, and it’s why Ontario customers call us back.
Response time to most Ontario neighborhoods is 30-45 minutes for emergency calls. For scheduled lock installation or rekey work, we confirm a window in writing when you book.
Our Lock Installation & Rekey Services in Ontario

Smart Lock Installation
Smart lock installation in Ontario runs $160-$320 depending on the lock model and the condition of the door. The heat here is the wildcard. Ontario regularly hits 105-110°F in summer, and that degrades the rubber gaskets and battery performance in smart locks faster than the manufacturer’s rated specs. We install Yale and Baldwin smart locks and we’ll tell you plainly which models hold up better on a west-facing door that bakes all afternoon. If your door is a 1960s wood-frame original with a sagging strike plate, we correct that before mounting the lock. A smart lock on a misaligned door will eat batteries and eventually fail to throw the bolt.

Keyless Entry
Keyless entry installation runs $140-$260 in Ontario. For the apartment complexes built to house the logistics workforce along the I-10 corridor, keyless entry often means a keypad deadbolt on unit doors or a coded handle set on a common area. For the older single-family stock near Euclid Avenue, it usually means a keypad deadbolt on a front door that’s never been straight since original construction. We stock parts locally and can usually complete keyless entry installation the same day we quote it.

Keypad Lock
Keypad lock installation runs $130-$240. We recommend it for Ontario homeowners who’ve had one too many lockouts and for small commercial tenants who need to change codes between shifts. The install itself is straightforward. The Ontario-specific issue is the door: 1950s and 1960s tract homes commonly have 1-3/8″ door slabs with a small cross-bore, and a modern keypad deadbolt needs a 2-1/8″ bore and proper backset. That’s a 20-minute modification for us, not a reason to hang a flimsy surface latch.

Biometric Lock
Biometric lock installation in Ontario runs $280-$450. We’re honest about this one: a fingerprint reader makes sense on an interior door or a controlled commercial entry, not as the sole security on a residential front door that faces 110°F heat and direct sun. We install Mul-T-Lock and Sargent biometric hardware where the application fits. For most Ontario homes, we’ll recommend a quality keypad deadbolt instead and tell you why in writing. That’s the deal. You get our actual read on your door, not the higher-ticket item because it’s a line item.

Common Lock Installation & Rekey Problems We See in Ontario Homes

- Deadbolts seizing in August. Steel cylinders expand in heat, and a west-facing door on a 1950s tract home can see surface temperatures 20 degrees above ambient. A deadbolt that worked in June binds by Labor Day. The fix is usually a new cylinder with fresh pins, not a whole new lock.
- Misaligned strike plates on old wood-frame doors. Ontario’s hot days and cool nights make wood swell and shrink seasonally. The deadbolt no longer lines up with the strike plate, so the bolt doesn’t throw clean, and someone ends up forcing the key until it snaps. Rekeying alone won’t fix this. The strike plate needs resetting and sometimes the mortise pocket needs deepening.
- Original Kwikset hardware from the 1960s. Many central Ontario homes still run the original keyed entry locks and deadbolts. The pin-and-tumbler cylinders are so worn that a rekey doesn’t hold tolerances. When we rekeyed a 1960s tract home near the Model Colony Historic District, the original Kwikset deadbolt was so sloppy that new pins wouldn’t seat reliably. We replaced the cylinder, milled a deeper mortise pocket for a fresh ANSI Grade 1 deadbolt, and re-hung the strike plate so the bolt actually threw clean, without touching the homeowner’s original Baldwin trim.
- Smart lock batteries dying fast. Heat kills lithium batteries faster than cold does. If your smart lock is on a south- or west-facing door in Ontario and the batteries are dead in three months, the door alignment is usually the underlying problem. The motor is working against a misaligned bolt. We fix the door first, then judge the lock.

FAQs - Lock Installation & Rekey in Ontario

Most original Kwikset cylinders from the 1960s are too worn to rekey reliably. The pin chambers have opened up, and new pins won’t seat with the tolerances a rekey requires. We’ll inspect the cylinder on site and tell you straight: if it holds a key snugly, a rekey at $45-$95 per cylinder is fine. If it’s sloppy, replacing just the cylinder is usually the better move and runs $120-$220. Call (331) 310-8471 and we’ll give you a written answer for your specific locks.
Summer heat above 105°F makes steel deadbolt cylinders expand and bind, and that’s the most common cause of a sticking deadbolt in Ontario between June and September. Rekeying won’t fix a binding cylinder. Replacing the cylinder or lightly reaming the bore will. If the door itself has shifted and the bolt is dragging on the strike plate, that’s an alignment repair, not a rekey. We’ll diagnose it and quote it in writing before touching anything.
Yes, but only if the door is squared first. Older wood-frame doors in central Ontario swell and shift seasonally, and a smart lock motor working against a misaligned bolt burns through batteries in weeks. We’ll re-hang the strike plate and correct the alignment before installing the lock. For west-facing doors, we also recommend models with higher temperature tolerance. Smart lock installation runs $160-$320, quoted in writing before we start. Call (331) 310-8471 to get your door assessed and priced.
Yes. Ontario’s I-10/I-15 interchange makes it one of the densest logistics hubs in the US, and a big share of our lock installation and rekey calls are master-key systems for fulfillment centers, loading dock access control, and fleet-vehicle lockouts along the Milliken and Vineyard Avenue corridors. That’s work a residential locksmith in Upland or Montclair almost never sees. We schedule a site review, deliver a written scope, and quote a flat per-lock price. Call (331) 310-8471 to set it up.
Rekeying is almost always cheaper, at $45-$95 per cylinder versus $120-$280 for a new lock installed. But replacement makes sense when the cylinder is worn past the point of holding a key, when the lock is so pitted or corroded from Ontario’s heat that the mechanism is failing, or when you want a modern high-security keyway that can’t be cut at the big-box store. We’ll show you the worn parts before we recommend anything. Call (331) 310-8471 for an honest read and a firm written price.
