Rekey Locks in Ontario means working with two very different types of hardware on the same day: original mortise locksets in 1920s bungalows near Euclid and Holt, and builder-grade Kwikset knobs in the tract subdivisions north of the 10. That split, plus the dust that Santa Ana winds push into cylinders, makes rekeying here a job where the tech needs to carry both antique and modern pins on the same truck. If you need a locksmith in Ontario, call (877) 358-5506 for an honest quote before anyone is dispatched.
Why Ontario Homes Are Different
Ontario is an Inland Empire logistics hub. Thousands of warehouses, distribution centers, and truck yards line the 10 and I-15 corridors, which means locksmith work here skews heavily commercial: master-key systems, storefront mortise locks, panic hardware, and rekeying after tenant turnover in industrial parks. That is not the whole picture, though. Downtown and the older core blocks around Euclid and Holt hold 1920s through 1950s bungalows with original mortise locksets and solid wood doors. The northern and eastern subdivisions built from the 1980s onward use standard cylindrical knobs and deadbolts, plus gated communities with common-area master keying.
The climate adds another layer. Ontario’s hot, dry inland summers and blowing Santa Ana winds drive dust and grit into exterior locks and hinges. Cylinders seize, keys stick, and plastic smart-lock keypads yellow and degrade faster than they would in coastal LA. We see that pattern constantly: a lock that worked fine in spring gets stubborn by late summer because fine dust has worked its way into the pin chambers. Rekeying a lock like that without cleaning the cylinder first just moves the grit around.
Styles & brands we work with
Our Main Ontario Services
Most Ontario homeowners and drivers call us for one of two things: a car key that needs replacing, or a lockout that cannot wait. Here is what each involves in this city.
Car Key Replacement in Ontario
The Ontario Mills lots and the airport parking structures generate a steady stream of car key problems: snapped keys, lost fobs, and transponder keys that stopped communicating. In this heat, key fob batteries die faster than the manual says they should. We cut and program replacement keys for most makes on the spot, and because we are a full-spectrum locksmith, you are not calling a separate automotive specialist for this. See the details on our Car Key Replacement in Ontario page.
Emergency Locksmith in Ontario
Locked out of a house near the 60, or standing next to your truck at a yard off Milliken with the keys on the seat, the priority is getting you back in without damaging the hardware. Our emergency response covers residential, commercial, and vehicle lockouts around the clock. We open the lock, not destroy it, wherever that is possible. Read more on our Emergency Locksmith in Ontario page.

Rekey Locks in Ontario
Rekeying in Ontario solves two recurring local problems: old mortise locks that have not been changed in decades, and the constant tenant turnover in this city’s apartment complexes and industrial parks. A rekey means we change the pins inside the existing lock so the old keys stop working entirely. It is the fastest, most affordable way to take control of who has access, and it costs far less than replacing hardware. That is why we treat rekeying as our Rekey Locks core service, not an add-on.
Lock Rekey
Signs you need it
If you have lost a key, moved into a home where a previous owner or tenant might still have copies, or just cannot account for every key that was ever handed out, the lock needs rekeying.
What it costs in Ontario
A standard Lock Rekey in Ontario typically runs $65 to $180 depending on how many cylinders are involved and whether they are standard or mortise.
How we do it
We remove the cylinder, clear out the old pins, install a new pin configuration matched to a fresh key, and test the lock through a full turn cycle before we leave.
Rekey Door Lock
Signs you need it
You just bought a house in one of Ontario’s older neighborhoods, or you have had work done by contractors, cleaners, or pet sitters and want to be certain no extra keys are floating around.
What it costs in Ontario
A Rekey Door Lock job in Ontario typically costs $18 to $25 per cylinder in labor, plus a trip charge that varies by distance, so a typical two-lock entry door lands around $65 to $95 all in.
How we do it
We pull each cylinder, decode the existing keyway, swap the pins to a new key code, and reinstall the cylinder with the same fit and finish it had before.
What Rekey Locks Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Per-cylinder rekey labor | $18 – $25 |
| Standard lock rekey (1-3 cylinders) | $65 – $180 |
| Mortise lock rekey (older homes) | $85 – $180 |
Is it cheaper to rekey or replace a lock in Ontario?
Rekeying is almost always cheaper. Replacing a lock costs $40 to $300 per lockset just for hardware, plus labor, while rekeying reuses your existing hardware and runs $18 to $25 per cylinder. Call (877) 358-5506 for an exact quote on your specific locks.
How long does a rekey take in Ontario?
Most residential rekeys take 20 to 40 minutes for one to three locks. Older mortise locks take a bit longer because the cylinder has to be extracted and cleaned. Call (877) 358-5506 and we will give you a straight time estimate.
Brands We Service in Ontario
We work on Kwikset, Medeco, Yale, and Baldwin hardware daily, and we carry common pins, springs, and tailpieces for all four on the truck. A Medeco high-security rekey takes a little longer because the angled cuts require precise pinning, but we do it in one visit. See our brands for the full list.

What pushes a price up in Ontario is usually the age of the hardware. A 1940s mortise lock full of dust takes longer to rekey than a clean modern cylinder, and that labor shows up in the quote. We give you the full price on the phone before we dispatch, and that is the price on the invoice, no arrival surcharge.
