Fast, Reliable Change Door Locks Across Fontana
Changing door locks in Fontana typically costs between $95 and $240 per door for a standard knob or deadbolt swap, and most jobs are completed the same day we get your call. The work takes under an hour per door when the existing bore and strikeplate are in decent shape. We serve every corner of Fontana, from the 1950s ranch houses near the old downtown core to the stucco tracts along Duncan Canyon Road and the acreage pockets off Sierra Avenue. Call (910) 714-4287 and you’ll get a live person, not a recording.
What sets Fontana apart from most cities our size is how much ground one property can cover. A house on a half-acre off Citrus might have a detached workshop, two driveway gates, and a back slider all on different keys. That changes how we approach a Change Door Locks job. We plan for the whole property, not just the front door, and we arrive with the key blanks and hardware to do it in one visit.
Why Dunmore Locksmith Is Fontana’s Preferred Change Door Locks Company
Dunmore Locksmith has been part of the Threshold Group family since 2007, and the way we operate in Fontana comes straight from the Threshold Standard: every technician is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. You’ll know exactly who is walking up your driveway before they knock. If someone shows up who you weren’t told to expect, that visit is covered at no charge. Perry Osgood, who leads our team, built this process because opening your door to a stranger should never be a leap of faith.
Fontana homeowners tell us the same thing across every neighborhood: they want to know the price before the work starts, and they want it in writing. That’s how we operate. The quote you get on the phone is the price on the invoice, and we hand it to you in writing before a single screw comes out. No arrival surcharges, no bait pricing. If the repair fails within 365 days, we come back and make it right at no charge. That’s the 365-Day Done Right Promise, and it’s stamped on every job we do in Fontana.
We also answer the phone like a local business, because we are one. A live person picks up 24 hours a day, seven days a week. When you call about a lock change on a Saturday morning before the heat sets in, you’ll talk to someone who can dispatch a technician to Fontana the same day.
Patio Door Lock Change in Fontana
Patio Door Lock Change in Fontana usually runs $110 to $190 for the hardware and labor, and it’s one of the calls we make most often in the southwest-facing stucco tracts where sliding glass doors bake in the afternoon sun. The thin pot-metal latch that came with the original builder slider often fails after a decade of Fontana heat, leaving the door that faces the backyard the weakest point in the house. We swap it for a Schlage or Kwikset patio lock with a hardened bolt and strike, and we adjust the roller track while we’re there so the door isn’t fighting its own frame.
Sliding Door Latch and Claw Replacement
The claw-style latch on older sliding doors in Fontana seizes when dust from the Santa Ana winds works into the mechanism. Rather than forcing it, we replace the latch assembly and realign the keeper. The new claw grips the frame instead of just resting against it.
Keyed Patio Door Deadbolts
Some Fontana homeowners want their slider to key from the outside like any other exterior door. We can cut in a keyed deadbolt at the stile, match it to the rest of the house key, and leave you with one key running the front door, the back slider, and the side gate.
Door Lock Change in Fontana
Door Lock Change in Fontana starts around $95 for a single knob or deadbolt on a clean, standard bore and goes up from there based on hardware grade and whether the old hole needs work. What we see constantly in Fontana’s 1950s and 60s ranch homes near the old downtown core is a builder-grade deadbolt that’s been drilled out during a previous rekey. The face is chewed up, the bore is slightly enlarged, and a new deadbolt won’t sit square. We don’t just slap a new lock over a bad hole. We shim, align, and sometimes install a wrap plate so the new deadbolt throws clean and stays latched.
Knob Set and Deadbolt Swaps
A straightforward swap on a 1980s stucco tract home off Sierra typically means pulling the old Kwikset or Schlage, drilling new strike screw holes if the old ones are stripped, and handing you a freshly keyed lock with two or four working keys. The whole job takes under an hour per door.
Whole-Property Keying
On Fontana acreage, a door lock change often means three or four cylinders: house, detached workshop, gate, and sometimes a barn or tack room. We key every one of them to a single key during one visit. You’ll leave with one key that works every exterior lock on the property, and we’ll mark the non-house cylinders so you know exactly what you’re holding.
Trusted Brands We Service in Fontana
We’re factory-authorized on the hardware Fontana homeowners and business owners actually buy here: Schlage for deadbolts that shrug off Fontana’s heat, Kwikset for affordability on rental turnover rekeys, and Medeco or Yale when someone wants a high-security cylinder that can’t be copied at the hardware counter on Foothill Boulevard. We stock common Fontana parts on the truck so a Monday morning job on Cherry Avenue doesn’t stall out waiting on a key blank. If you want a bump-resistant deadbolt or a smart lock with a keypad on a detached workshop, we’ll get it installed the same day, not in a week.
Common Change Door Locks Problems We See in Fontana Homes
- Heat-warped frames. July and August regularly push past 105°F in Fontana, and stucco-backed door frames swell enough to misalign a strikeplate by an eighth of an inch. That’s enough to keep a brand-new deadbolt from throwing. We adjust the strikeplate during the same visit so the new lock actually works the next morning.
- Dust-seized cylinders on outbuildings. Gate and workshop locks on Fontana acreage sit in blowing dust and dry heat with zero maintenance, and they seize faster than anything on the house itself. A change-locks visit that ignores the driveway gate means a second trip and a second service fee.
- Drilled-out original deadbolts. The 1950s and 60s ranch homes around the old downtown often still have their original non-ANSI deadbolts, and past rekeys left the cylinders drilled through. A straight swap stalls on the enlarged bore, not the hardware. We shim and wrap-plate as needed.
- Failed patio door latches. The cheap claw latches on original sliders in Fontana’s 1980s tract neighborhoods break under years of heat and dust. The door will still slide, but it won’t actually lock. That’s a security failure on the most exposed door in the house.
Pricing for Change Door Locks in Fontana, CA
A standard Door Lock Change in Fontana runs $95 to $140 per door for a knob or single-cylinder deadbolt, including labor. A patio door lock runs $110 to $190. Upgrading to a Schlage bump-resistant deadbolt or a Medeco high-security cylinder pushes the per-door price to $180 to $320, and that’s worth it on the ranch houses near Jurupa Hills where windows face open hillside and no one wants a copied key floating around. Whole-property keying, like a house, two gates, and a workshop all matched to one key, typically lands between $250 and $450 depending on cylinder count. The price we quote on the phone is the full price, in writing, before any work starts. Call (910) 714-4287 and Perry Osgood’s team will give you an exact number for your Fontana property.

FAQs About Change Door Locks in Fontana
Yes. We key residential knobs, deadbolts, gate cylinders, and outbuilding locks to one key during one visit to your Fontana property. Just tell the dispatcher every lock you want included when you call (910) 714-4287, and we’ll arrive with enough cylinders and key blanks to do the whole job that day.
In most cases, yes. The original deadbolts on those older Fontana homes are non-ANSI and often drilled out from past rekeys, which makes rekeying a weak short-term fix. We’ll show you the condition of the cylinder and faceplate before recommending a swap to a modern ANSI deadbolt. The price is in writing first, so you’ll know exactly what a replacement costs before we touch it.
Because Fontana’s summer heat warps the stucco-backed door frame, shifting the strikeplate just enough that the patio latch won’t seat. We fix it by adjusting the strikeplate and realigning the roller track during the lock change, not by lubing the latch and hoping it holds. A patio door lock change in Fontana usually solves the August jam for good.
Yes, and it’s measurable. Fontana’s fine particulate dust from the inland valley and Santa Ana winds works into cylinders and degrades the internal pins and springs faster than the marine air 40 miles west. Locks that would last 12 years in a coastal city can seize in six or seven here, especially on gates and outbuildings that never get greased. That’s why we stock extra cylinders on the truck for Fontana calls.
We can, but the right answer depends on distance and signal. For a workshop within 50 feet of the house, a Schlage Encode or similar Wi-Fi smart lock works fine. For a gate or outbuilding at the back of a larger Fontana lot, we usually recommend a commercial-grade mechanical keypad that doesn’t rely on Wi-Fi at all. We’ll walk you through both options on the phone, with written pricing before we dispatch.
