Rekeying locks is the smartest first move when you buy a home, lose a key, or take over a rental property in Ontario. We handle everything from 1950s mortise locks near downtown to newer Kwikset and Schlage deadbolts in the tract subdivisions off Archibald and Euclid. The Ontario climate – hot, dry summers and Santa Ana winds – bakes exterior hardware and warps door jambs, which means rekeying here often involves realigning the lock body, not just swapping pins. Call (855) 382-0290 and we’ll quote the full price before anyone rolls out.
Why Ontario Homes Are Different
Ontario’s housing stock spans three distinct eras, and each one changes how a rekey job goes. The mid-century single-story homes near the historic core – think the neighborhoods around Euclid Avenue and Holt Boulevard – still carry original builder-grade knob locks and, in a surprising number of cases, mortise lock sets. Those mortise bodies haven’t been stocked by local parts counters in decades, so a standard rekey often requires drilling out the old cylinder and retrofitting a modern one into the same footprint. It’s doable, but it’s not a quick pin-swap.
Then you have the 1980s and 1990s stucco subdivisions spread across 91762 and 91764. These homes run standard KW1 and SC1 keyways, which makes rekeying straightforward. But Ontario’s climate adds a wrinkle. The dry heat and seasonal Santa Ana wind events dry out wooden doors and jambs. A deadbolt that latched fine in March can suddenly bind in September because the door slab has shifted. We see this constantly in Ontario. A good rekey here includes checking and adjusting the strike plate alignment so the new key doesn’t fight the hardware.
Finally, the industrial tilt-up buildings and auto-closure retail spaces along the 60 and I-15 corridors need commercial-grade key control. For property managers with multiple tenants, rekeying between turnovers is a routine security measure. The dust from the foothills accelerates cylinder wear, especially on exterior padlocks and gate locks, so we recommend higher-quality pins and occasional cylinder cleaning.
Styles & brands we work with







Our Main Ontario Services
Rekeying is what most Ontario homeowners and property managers call us for, but two other services come up just as often: replacing car keys and responding to lockouts after hours. Here’s how each works in Ontario specifically.
Car Key Replacement in Ontario
Ontario’s position in the Inland Empire logistics corridor means a lot of residents commute to warehouse jobs in Rancho Cucamonga, Fontana, and Chino. When a car key breaks in the ignition at 6 a.m. before a shift, waiting days for a dealership isn’t realistic. We cut and program replacement keys for most makes and models right here, often in the driveway or a parking lot off Milliken. Ontario’s heat kills key fob batteries faster than coastal areas, so we see more remote failures and worn buttons. If you need this done, our full Car Key Replacement in Ontario page has the details on transponder programming and what to expect.

Emergency Locksmith in Ontario
Lockouts in Ontario split two ways: residential calls from the older neighborhoods where a warped jamb has seized a deadbolt shut, and commercial lockouts at the truck yards and distribution centers along the 60, where a padlocked gate or a jammed trailer door stops a whole shift. We respond around the clock with the right tools for both. The full picture – including what to do while you wait and how we handle damaged hardware – lives on our Emergency Locksmith in Ontario page.

Rekey Locks in Ontario
Rekeying a lock means changing the internal pins and springs so old keys stop working and new ones take their place. In Ontario, this service makes special sense for the aging housing stock near downtown where original locks are still in service, and for rental properties across 91762 and 91764 that change tenants regularly. The dry climate here accelerates cylinder wear, so rekeying often pairs with a quick cleaning and lubrication to keep the new pins turning smoothly. Learn more about the full process on our Rekey Locks page, or keep reading for exact pricing and what to look for.
Lock Rekey
Signs you need it
You’ve lost a key, don’t know how many copies are floating around, or recently moved into a home in Ontario and can’t confirm who has the previous keys.
What it costs in Ontario
Standard lock rekeying in Ontario runs $15 to $25 per cylinder for most residential Kwikset and Schlage hardware.
How we do it
We remove the cylinder, replace the bottom pins and springs to match a new key, and reassemble the lock so old keys no longer work.
Rekey Door Lock
Signs you need it
Your deadbolt binds or sticks in Ontario’s dry, dusty conditions and the key feels like it’s wearing the pins down faster than it should.
What it costs in Ontario
Rekeying a door lock in Ontario is $15 to $25 per cylinder, with no trip-charge surprise added when we arrive.
How we do it
We pull the lock body, swap the pins to a new keyway pattern, and realign the strike plate if Ontario’s seasonal door warp has thrown it off.
Keyed Alike
Signs you need it
You carry separate keys for the front door, back door, and garage, and you’d rather have one key that turns everything on your Ontario property.
What it costs in Ontario
Keyed-alike service in Ontario is $15 to $25 per cylinder to set multiple locks to a single common key.
How we do it
We pin each cylinder to the same bitting pattern so one key opens every lock you specify, then test each one before we leave.
What Rekey Locks Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Residential rekey, per cylinder | $15 – $25 |
| Mortise lock retrofit (older Ontario homes) | $40 – $85 |
| High-security rekey (Medeco, Mul-T-Lock) | $25 – $45 |
How much does it cost to rekey locks in Ontario?
Most Ontario homes cost $15 to $25 per cylinder, so a typical front and back door with two cylinders runs $30 to $50 in labor and parts. Mortise locks on older homes near downtown run higher. Call (855) 382-0290 for an exact quote before we dispatch.
Is rekeying better than replacing locks in Ontario?
Rekeying is cheaper and usually smarter when the existing hardware is in good shape. But if Ontario’s heat and dust have corroded the cylinder or the latch is worn, replacement is the honest call. We’ll tell you which one your locks actually need. Call (855) 382-0290 and we’ll walk you through it.
Brands We Service in Ontario
We work on Kwikset, Schlage, and Medeco daily across Ontario, and we keep common KW1 and SC1 pins and springs stocked on the truck for same-visit rekeys. High-security Medeco cylinders take a little longer since the pins are precision-machined. For the full list of what we handle, see our brands.

Two things push prices up in Ontario more than anything else: the age of the hardware on mid-century homes near the historic core, and the commercial-grade cylinders on warehouse and distribution buildings along the 60 corridor. Whatever the job, the price we quote on the phone is the price on the invoice. We don’t add a call-out fee when we arrive.

What Ontario Customers Say
"Rekey was done properly. One of the keys he cut was slightly stiff in the back door and I had to call him to swap it, which he did without a fuss."
— Eric Kim"Does good work. Card payment was a bit of a production, so have another option handy."
— Craig Thompson"The old deadbolt was mounted crooked by whoever lived here before and had been sticking for years. He redrilled and reset it properly rather than just replacing the hardware."
— Neil Parker
