Rekeying locks is the most common job we handle in Fontana, and the reason is simple: this city’s housing stock was built in waves, which means thousands of homes share identical builder-grade hardware. When you buy a home in a tract built in 2004, your front door lock is likely the same Kwikset knob as every other house on the block, and that changes how a locksmith should approach your security. We’re Greystone Locksmith, and we’ve served Fontana since 2011. Call us at (866) 497-9415 for a free estimate on any lock work.
Why Fontana Homes Are Different
Fontana’s hot, dry Inland Empire climate does more to door hardware than most people realize. Triple-digit summers and Santa Ana wind events cause wood door frames and jambs to swell, warp, and crack. A deadbolt that worked smoothly in March can bind by July because the door slab itself has shifted. We see this constantly across ZIP codes 92335 through 92337, and it changes how we approach even a simple rekey: before we touch the cylinder, we check the strike plate alignment and the door’s position in the frame.
The housing stock itself is the other half of the story. South Fontana, particularly the Etiwanda area and the master-planned subdivisions in 92336 and 92337, contains block after block of tract homes built within a few years of each other. Those homes shipped with builder-grade entry hardware, mostly Kwikset and Schlage knobs and single-cylinder deadbolts. When a homeowner in one of these neighborhoods calls us, we already know what’s on the door before we arrive, because we’ve worked on hundreds of identical units in the same model-plan tracts. That’s not a limitation; it means we’ve already seen every failure mode that hardware can produce in this climate.
The older 92335 neighborhoods around downtown Fontana tell a different story. Those mid-century homes often still have thin, weathered door slabs and original single-cylinder deadbolts that have warped through decades of summer heat. On those doors, deadbolt reinforcement and strike-plate realignment come up as often as actual re-keys. A rekey puts new pins in the cylinder, but if the door doesn’t close square, the new key won’t fix the sticking. We address both in the same visit.
There’s also a Fontana-specific pattern worth naming: multi-generational households. In many homes here, adult children, in-laws, and extended family share the same address. When a key goes missing or a household shifts, the recurring question is “who gets a key.” That makes rekeying, not replacing, the right move for most Fontana families, and it’s why we treat rekeying as a core service, not an upsell.
Styles & brands we work with
Our Main Fontana Services
The two calls we hear most often from Fontana residents are car key emergencies and lockout situations. Both are covered below, and each has its own dedicated Fontana page with full detail.
Car Key Replacement in Fontana
Losing a car key in Fontana usually happens at the worst moment: at the Kaiser Fontana medical center parking lot, outside a warehouse shift off the 10 Freeway, or in a driveway on a 105-degree afternoon. We handle car key replacement in the field, meaning we come to you with the programming equipment on board. This matters for today’s vehicles, where transponder chips and proximity fobs require programming, not just cutting. Car Key Replacement in Fontana covers our full process and pricing.
Emergency Locksmith in Fontana
A lockout at midnight in Fontana is not the same as a lockout at noon. The heat, the distance between neighborhoods, and the reality that many residents commute long hours mean access failures pile up at odd times. Our emergency response is built for that: when every minute counts, you want a team that’s already prepared. Emergency Locksmith in Fontana explains how we handle urgent calls across the city.

Rekey Locks in Fontana
Rekeying locks in Fontana is the smarter alternative to full replacement in most cases, and it’s the service we recommend first. Because so many Fontana homes share identical builder-grade hardware, rekeying is fast and predictable: we pull the cylinder, swap the pins to match a new key, and you keep the existing hardware while the old keys stop working. In the hot, dry climate of the Inland Empire, where warped frames and sticky deadbolts are common, we also check strike plate alignment as part of the job. That’s the difference between a rekey that works on day one and one that binds six weeks later. For a full explanation of Rekey Locks, see our service hub page.
Lock Rekey
Signs you need it
You’ve moved into a new Fontana home, an ex-partner or roommate still has a key, or you’ve lost track of how many copies of your key are floating around.
What it costs in Fontana
Standard lock rekeying in Fontana typically runs $65 to $120 for the first cylinder, with additional cylinders at $15 to $25 each, depending on brand and hardware type.
How we do it
We remove the cylinder, replace the pins to match a new key, test the mechanism, and reinstall it, all while checking that the door closes square in the frame.
Rekey Door Lock
Signs you need it
A recent move, a change in household members, or a door lock that’s been in place since the home was built and has never been rekeyed.
What it costs in Fontana
Rekeying a single door lock in Fontana typically ranges from $75 to $140, with the higher end covering high-security brands like Medeco or Mul-T-Lock.
How we do it
We disassemble the lock, install new pins matched to a fresh key, and verify the key turns smoothly in both directions before we finish.
What Rekey Locks Costs in Fontana
| Item | Typical range in Fontana |
|---|---|
| First cylinder rekey | $65 – $120 |
| Each additional cylinder | $15 – $25 |
| High-security cylinder (Medeco, Mul-T-Lock) | $95 – $160 |
How much does it cost to rekey a house in Fontana?
Most Fontana homes have three to six keyed entry points, so a full-home rekey typically runs $150 to $300. The exact figure depends on how many cylinders you have and whether any are high-security. Call (866) 497-9415 for an exact quote before anyone is dispatched.
Can I rekey my own locks in Fontana?
You can, but rekeying kits from big-box stores are limited to Kwikset and Schlage, and they won’t work on Baldwin, Abloy, or Medeco hardware. A locksmith also recalibrates the cylinder so the new key doesn’t bind months later. Call (866) 497-9415 and we’ll give you a straight answer on whether it’s worth doing yourself.
Brands We Service in Fontana
We work on the lock in front of us, not just the brands we prefer. That means Schlage and Kwikset from the tract homes in 92336, Medeco and Abloy in the commercial properties near the 10 and 15 freeways, and Baldwin hardware on a handful of custom homes in the area. See our brands page for the full list. Because we carry parts for all of these locally, most rekey jobs are completed same day, even when the hardware is less common.

FAQs About Locksmith in Fontana
Our typical response time in Fontana is 30 to 45 minutes for emergency calls, longer during rush hour when the 10 and 15 freeways back up. We cover every ZIP code in the city, from 92335 near downtown to 92337 in the south. Call (866) 497-9415 and we’ll give you an accurate arrival window for your specific address.
No. Rekeying or replacing locks on a home you own or rent does not require a permit from the City of Fontana, and HOAs cannot restrict your right to secure your own door. The only exception is if the lock hardware is visible from the street and a strict HOA has an architectural review rule, which is rare. We handle the hardware, not the paperwork.
Yes. The price we quote on the phone before dispatch is the price on your invoice. We don’t add a call-out surcharge when we arrive, and we don’t quote a teaser price that balloons after the technician sees the lock. That’s a known problem in this trade, and we answer it directly because it’s the main reason people hesitate to call. Call (866) 497-9415 for a free estimate.

What Fontana Customers Say
"Rekeyed every lock in the house the day after we closed. Six doors, all matched to one key, done in about ninety minutes."
— Yolanda Martinez"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."
— Brooke Ackerman"Programmed a transponder key for a 2014 model that the dealership wanted an absurd amount for. Same key, fraction of the price, took him twenty minutes in my driveway."
— Grace Lin
