Rekeying is the service Ontario homeowners and warehouse managers call about most, and for good reason. A rekey costs a fraction of replacing hardware and resets security in under an hour. In Ontario’s mix of 1950s tract homes and newer master-planned subdivisions, plus the commercial corridors along I-10, the common thread is this: locks get worn, keys get copied too many times, and access needs change. We handle all of it. Call (877) 265-3856 for a straight answer on your lock situation.
Why Ontario Homes Are Different
Ontario sits in a hot, dry stretch of the Inland Empire, and that heat does measurable things to door hardware. Through July and August, wood frames and metal strike plates expand at different rates. The result is a deadbolt that binds, a latch that won’t seat, or a key that turns fine one afternoon and fights you the next. We see a spike in binding-deadbolt calls every summer in the older neighborhoods west of Euclid Avenue, where mid-century tract homes still carry their original single-cylinder deadbolts and knob locksets from the 1950s through the 1970s.
The housing stock changes block to block. The 91761 and 91762 growth areas lean newer, with builder-grade Kwikset or Schlage hardware that works well but wears faster than premium lines. The commercial picture is different again. Ontario’s position as a logistics hub along the I-10 corridor means warehouse and distribution-center rekeys, master-key systems, and fleet-lot lockouts make up a large share of our calls, far more than in neighboring Inland Empire cities where residential lockouts dominate. Walk the warehouse rows near Ontario International Airport and you’ll find interchangeable core cylinders and SFIC pinning as the standard, not the exception. That’s a different toolset and a different skill level than a standard residential call.
Styles & brands we work with
Our Main Ontario Services
Two services account for most of the calls we answer in Ontario: car key replacement and emergency lockout response. Here’s what each involves locally.
Car Key Replacement in Ontario
Losing a car key in Ontario usually means being stranded at a logistics-center parking lot, a Metrolink station, or a retail strip along Ontario Mills. We cut and program replacement keys, transponder keys, and fobs on-site for most makes. The heat matters here too: key fob batteries die faster in extreme interior temperatures, and worn ignition cylinders are common in older vehicles that bake in Inland Empire sun all day. Car Key Replacement in Ontario covers what we do vehicle by vehicle.
Emergency Locksmith in Ontario
A lockout in Ontario at midnight is a different situation than a lockout at noon. Commercial truck lots and warehouse docks are active around the clock along the I-10 corridor, and residential calls come in from every ZIP code we cover. We respond to home lockouts, business lockouts, and vehicle lockouts without a call-out surcharge added on arrival. Emergency Locksmith in Ontario explains response times and what to expect before we arrive.

Rekey Locks in Ontario
Rekeying a lock means changing the internal pins so the old key stops working and a new key takes over. In Ontario, we rekey for three reasons more than any others: a tenant or employee has moved on, a key has gone missing, or a homeowner just bought a 1960s tract house and has no idea how many spare keys are floating around the neighborhood. The hot, dry climate adds a mechanical factor: pins and springs in older locks wear faster, and a rekey with fresh pins often resolves a stiff or sticky cylinder at the same time. Rekey Locks is the full service breakdown for anyone considering it.
Lock Rekey
Signs you need it
A key you don’t recognize, a recent move, a housekeeper or contractor who had a copy, or a lock that hasn’t been changed in a decade.
What it costs in Ontario
Standard rekeying in Ontario runs $18 to $25 per cylinder in labor, plus $5 to $15 per new key, with a service call fee of $45 to $85.
How we do it
We remove the cylinder, swap the old pins for a new pin set matched to a fresh key, then reinstall and test the lock so only the new key operates it.
Rekey Door Lock
Signs you need it
The key works but turns stiffly, the lock is original to a 1950s or 1960s home, or you can’t account for every copy of the current key.
What it costs in Ontario
Rekeying a door lock runs the same $18 to $25 per cylinder, with the $45 to $85 service call fee covering the visit to your Ontario property.
How we do it
We disassemble the lock, clean out old pin debris, install new springs and pins where needed, and cut a new key that operates the rekeyed cylinder.
Rekey Service
Signs you need it
You need multiple locks working from the same key, or you just took ownership of a commercial space and have no record of how many keys exist.
What it costs in Ontario
A multi-lock rekey service is priced per cylinder at $18 to $25 each, with new keys at $5 to $15 apiece and the standard $45 to $85 service call.
How we do it
We inventory every lock on the property, rekey each cylinder to the new key or to a keyed-alike arrangement, and hand over control of the full key set.
What Rekey Locks Costs in Ontario
| Item | Typical range in Ontario |
|---|---|
| Service call fee | $45 – $85 |
| Rekey labor per cylinder | $18 – $25 |
| New key per copy | $5 – $15 |
How long does a rekey take in Ontario?
Most single-home rekeys take 20 to 45 minutes on-site. Multi-lock commercial jobs in Ontario’s warehouse district run longer, often a half-day, depending on cylinder count and keying system. Call (877) 265-3856 for a time estimate on your property.
Is rekeying better than replacing locks in Ontario?
Usually yes. Rekeying keeps your existing hardware and resets security for $18 to $25 per cylinder, versus $40 to $120 per new lock. We only recommend replacement when the hardware is damaged or you want a premium upgrade.

Pricing for Locksmith in Ontario, CA
| Service | Typical range in Ontario |
|---|---|
| Service call fee | $45 – $85 |
| House lockout | $75 – $130 |
| Car lockout | $60 – $120 |

What pushes a price up in Ontario is usually the lock’s age and hardware type. Older tract-home locks with worn cylinders take longer to rekey cleanly, and high-security commercial systems like Medeco or Mul-T-Lock cost more because the cylinders and key blanks are more expensive. Every job gets a full price quoted on the phone before anyone is dispatched, and that is the price on the invoice: no arrival surcharge, no bait number.

FAQs About Locksmith in Ontario
Most Ontario lockouts get a technician on-site within 30 to 60 minutes. The commercial area around the airport and I-10 is the fastest zone because we keep trucks staged near the warehouse clusters. The northern residential blocks can run slightly longer during late-night hours. Call (877) 265-3856 and we’ll give you a real ETA for your street, not a generic window.
No permit is required for residential rekeying or lock replacement anywhere in Ontario. Commercial properties may have lease or insurance requirements, especially in the warehouse and logistics sector where access control and fire-code hardware checks apply. A locksmith can advise, but the city itself does not require a permit for lock work.
Yes. We service 91762, 91764, 91758, and the 91761 growth area, plus the commercial zones around Ontario International Airport. If you’re in an Ontario ZIP but close to a neighboring city line, we still dispatch. Tell us your cross streets and we’ll confirm the address while you’re on the phone.
