Fast, Reliable Rekey Locks Across Fontana
Rekeying a lock in Fontana means swapping the internal pins so old keys stop working, without replacing the hardware itself. Most rekey jobs cost between $40 and $95 per cylinder here, and a standard residential rekey for two or three exterior doors runs roughly $120 to $285. You’ll get a written price before we dispatch, a live arrival time you can track, and a guarantee that covers the work for a full year. Call (409) 405-4485 and you’ll talk to a live person, not a voicemail tree.
We serve every part of Fontana, from Catawba Hills to Sierra Lakes to the older ranch streets near downtown. Kevin Yoon leads our team, and he has built Preston Locksmith & Security around one promise: the price quoted on the phone is the price on the invoice. No exceptions, no surcharge added when the tech arrives.
Why Preston Locksmith & Security Is Fontana’s Preferred Rekey Locks Company
Fontana homeowners want a locksmith who shows up when promised and charges what was quoted. Our response time to most Fontana neighborhoods runs 30 to 45 minutes, and every job is backed by the 365-Day Done Right Promise. If the rekey isn’t done right, we make it right. That guarantee is stamped on every repair, in writing, no fine print.
We also give you before-and-after photos of every job and a live trackable arrival time through The Relay Visibility Guarantee. You’ll know the technician’s name, what they look like, and exactly when they’ll be at your door before they knock. That’s a real difference when you’re sitting in a Fontana living room wondering if the person outside is actually the locksmith you called.
Our technicians are background-checked and arrive in uniform. They carry rekey kits for Schlage, Kwikset, Medeco, and Yale hardware, so the job usually gets done in one visit, not two.
Lock Rekey in Fontana
Lock rekey in Fontana is the fastest, least expensive way to take back a key. We pull the cylinder, replace the pin and tumbler stack with a fresh set sized to a new key, and reinstall it. Your old keys stop working immediately. The hardware you already own stays in place, which keeps costs down and avoids the mismatched finishes you often get when swapping in new locks. For most Fontana homes, a lock rekey runs $40 to $95 per cylinder depending on brand and lock type, and the written price is confirmed before any work begins.
When a Rekey Makes Sense
You bought a house in the Citrus area and have no idea how many copies of the old key are floating around. Or you had a roommate move out of a rental off Sierra Avenue. Both are textbook rekey situations. It’s also the right call after losing a key, after a tenant change, or after any falling-out where you don’t want someone’s key working anymore.
What a Rekey Physically Involves
The technician removes the lock cylinder, takes out the old pins and springs, and inserts a new pin configuration matched to a fresh key. The whole process takes about 15 to 20 minutes per lock on a standard deadbolt or knob. If you have an older mortise lock, like we see on many downtown Fontana ranch homes, it takes a little longer because those cylinders use a different pinning method.
Locksmith Rekey in Fontana
Locksmith rekey in Fontana means bringing a trained professional to your home instead of guessing with a cheap rekey kit from a hardware store. We see the results of those DIY kits on a regular basis: pins that don’t seat correctly, cylinders that bind, and keys that work maybe half the time. A professional rekey costs $40 to $95 per cylinder here, and you get a guarantee the work was done correctly. If the lock fails within a year, the second visit is free.
Builder-Grade Versus High-Security Cylinders
Fontana’s housing stock isn’t uniform. The tract homes built in the 1990s and 2000s in neighborhoods like Catawba and Sierra Lakes often have builder-grade Kwikset cylinders. Older homes near downtown frequently have Schlage mortise locks or Baldwin hardware that take different pinning kits. We price the rekey by the actual lock you have, not by a generic “per door” assumption. That’s why we confirm the brand and lock type when you call, before anyone is dispatched.
Multi-Lock Discounts
Rekeying one lock is straightforward. Rekeying five or six is where a small discount helps. If you’re doing every exterior door plus a side gate or garage entry, ask about our multi-cylinder pricing when you call. We’ll give you a written total before the truck rolls.
Trusted Brands We Service in Fontana
We carry rekey kits for Schlage, Kwikset, Medeco, and Yale on every Fontana truck, alongside parts for common commercial cylinders. That means we don’t have to leave mid-job to grab a pin kit from a supplier. For older downtown homes with Schlage mortise locks, we stock the right pins. For newer Catawba and Sierra Lakes tract homes with Kwikset deadbolts, we carry those kits too. If you have a Medeco high-security cylinder on a commercial property off Valley Boulevard, we can rekey it without sending you to a specialty shop or making you wait a week.
Common Rekey Locks Problems We See in Fontana Homes
- Mismatched lock brands on the same house. A front door with a Schlage deadbolt and a back door with a Kwikset knob is common in Fontana. Each takes a different pin kit, and a phone quote that assumes one brand will be wrong. We confirm brands before dispatch.
- Mortise locks on older downtown ranch homes. These need a different set of pinning tools and a longer service window than a standard modern cylinder. We plan for that, so the job doesn’t stretch into a second visit.
- DIY rekey kits that didn’t work. Homeowners buy a $15 kit online, the pins don’t match their cylinder, and now the lock is half-disassembled. We fix it, but it costs more than calling us first would have. A written scope and price before dispatch avoids this entirely.
- Keys that work intermittently after a bad rekey. Dry climate, dust, and cheap pins make a weak rekey fail fast in Fontana. Our work is backed by the 365-Day Done Right Promise, which includes a free second visit if the repair fails.

FAQs About Rekey Locks in Fontana
Yes, sometimes. A standard Kwikset pin-and-tumbler cylinder and a standard Schlage residential cylinder are both in the $40 to $70 range per cylinder, but an ANSI Grade 1 Schlage B60 or a high-security Medeco cylinder costs more to rekey because the pins are different and the labor takes longer. We confirm the brand and lock type when you call so the written price is accurate before anyone is dispatched. For an exact quote on your locks, call (409) 405-4485.
A standard deadbolt or knob rekey takes 15 to 20 minutes per lock. A full front door with a deadbolt and handle set runs about 30 to 40 minutes. Older mortise locks on downtown Fontana homes take longer, usually 45 minutes to an hour per lock. We’ll give you an accurate time window on the phone, not a vague four-hour block.
Rekeying changes the internal pins so the old key stops working, while keeping the hardware you already have. Changing locks means buying and installing entirely new hardware. Rekeying is cheaper, faster, and keeps your existing finish and style consistent. Most Fontana homeowners rekey when they move in, lose a key, or part ways with a roommate or tenant. Call (409) 405-4485 and we’ll tell you which option fits your situation and your budget.
