Rekey Locks in Ontario - Flat Per-Lock Price, Quoted on the Phone

Fast, Reliable Rekey Locks Across Ontario

Rekeying a lock with our Ontario Residential Locksmith service typically costs $25 – $45 per cylinder when we come to you, and most houses are done in under an hour on site. A rekey changes the internal pins inside your existing lock so the old keys stop working, without replacing any hardware. If you just moved into a home near the Ontario Mills or closed on a 1950s ranch off Euclid Avenue, call us at (409) 405-4485 and we’ll give you a written price for every cylinder before a tech heads your way.

Call (409) 405-4485

We know Ontario’s streets, its housing mix, and the difference between a Kwikset repair in Ontario on a 1962 tract home and a Schlage deadbolt on a 2005 infill build near the airport. That local knowledge means our quotes cover the actual lock hardware on your doors, not a generic guess. No call-out surcharge when the van arrives. No price that shifts between the phone call and the invoice.

Why Preston Locksmith & Security Is Ontario’s Preferred Rekey Locks Company

We’ve been doing Rekey Locks work across Ontario long enough to know what’s behind most front doors here. Mid-century Kwikset knobs with original KW1 cylinders. Newer Schlage B60 deadbolts on the infill housing near the Ontario International Airport corridor. Baldwin hardware on the larger homes north of the 10. Every quote we give accounts for the actual pin and tumbler kits those locks need, because our techs carry them all. That’s the whole job: knowing what you’re walking into before you ring the bell.

Kevin Yoon leads our crew, and every tech he sends to an Ontario address is background-checked and in uniform. You know who’s coming, what they look like, and when they’ll arrive because The Relay Visibility Guarantee puts a live trackable arrival time on your phone. We include before-and-after photos of every rekey with your digital invoice. And the 365-Day Done Right Promise means if something isn’t right with the rekey, we come back and fix it at no charge. Written. Stamped on the invoice.

Calls are answered by a live person, 24/7, out of our Inland Empire office that dispatches locally to Ontario. No voicemail tree, no callback queue, no “the tech will call you when he’s close.” You call. We answer. We give you a written price. Then we send a tech with a live arrival window you can track.

Rekey Deadbolt in Ontario

A Rekey Deadbolt in Ontario usually runs $25 – $45 per cylinder, and it’s the most common single-lock job we do after a move-in, a roommate change, or a lost key. The work involves removing the deadbolt’s cylinder, replacing the internal pins and springs with a fresh pin set, and cutting new keys to match. The existing deadbolt stays on the door. The old key stops working the moment we finish the pin swap. No new hardware, no drilling, no drywall dust.

After a Closing or a Tenant Change

You don’t know who still holds a copy of the old key. The previous owner’s contractor, a neighbor who watched the house, the tenant who moved out in a hurry. Rekeying the deadbolt wipes all of that out. We hand over two new keys per adult and confirm the old ones no longer turn the cylinder before we leave.

Garage Service Doors and Side Entries

A deadbolt on the garage walk-in door or a side yard gate often gets skipped during a rekey. That leaves the back side of the house on the old key while the front door is on a new one. In Ontario, where garage access doors are common on both ranch homes and newer builds, we recommend counting every exterior deadbolt cylinder in the quote, not just the front.

Rekey House in Ontario

A full Rekey House in Ontario typically runs $90 – $180 for a standard three-to-four cylinder home, written price confirmed on the phone before anyone is dispatched. The job means rekeying every exterior lock cylinder: front door, back door, garage service door, and any side gate deadbolt. We swap the internal pins in each cylinder so all the locks work on one new key, while every prior key stops working. The hardware on your doors does not change.

Standard Ranch Tracts and Infill Homes

Ontario’s housing stock mixes mid-century ranch tracts with newer infill near the airport corridor, so a single street can hold both 1-3/8″ bore Kwikset knobs and 2-1/8″ Schlage deadbolts. A proper house rekey quote here has to account for two different pin and tumbler kits before the tech leaves the van. That’s why we quote cylinder counts, not “a lock,” on the phone.

Keyed-Alike on One Key

Most Ontario homeowners want every exterior lock on a single key. We set all your cylinders to the same pin configuration during a house rekey, so the key that opens your front deadbolt also opens the back door and the garage walk-in. You still get two keys per adult. If you want different keys for different doors, we can pin them separately too, but almost nobody asks for that on a residence.

Trusted Brands We Service in Ontario

We service and rekey Schlage, Kwikset, Medeco, and Abloy hardware across Ontario, from standard residential deadbolts to Ontario Commercial Locksmith high-security cylinders. If your 1960s ranch still has the builder’s original Kwikset knobs, we carry KW1 pin kits. If your place near Ontario Ranch has newer Schlage B60 deadbolts, we carry SC1 pin kits. We stock local parts in our Inland Empire office, so a routine rekey doesn’t turn into a two-visit job because the tech had to run for a pin set. The price you’re quoted covers the pins, the labor, and the new keys. Written. Before work starts.

Common Rekey Locks Problems We See in Ontario Homes

• Teaser pricing that balloons at the door. A quote that starts low and then climbs because the tech counts each lock cylinder as a separate trip charge. We give you the full cylinder count and the total price on the phone, in writing, before dispatch.
• Wrong pin kit on the truck. Ontario’s mix of older Kwikset and newer Schlage deadbolts means a single-kit van has to leave and return, turning a 30-minute rekey into a two-visit job. Our techs carry both kits as standard for every Ontario call.
• Skipping key control. Rekeying only the front door and leaving the garage service door on the old key defeats the point after a closing or a roommate change. We count every exterior cylinder in the quote.
• Unproven identity at the door. You called one number, and a stranger with a van shows up. Our techs arrive in uniform, are background-checked, and you get their name and photo before they knock. The Relay Visibility Guarantee puts a live trackable arrival time on your phone.

A homeowner near Euclid Avenue and the 60 had just closed on a 1962 ranch where every exterior door still carried the builder’s original Kwikset KW1 cylinders, and three prior owners’ keys were still floating around the neighborhood. Our tech rekeyed all four lock cylinders on site with fresh pins, kept the existing hardware, and handed over two new keys per adult, no hardware replacement needed. The homeowner paid the quoted flat rekey price, not a hardware markup.
