Fast, Reliable Rekey Locks Across Fairfax
Rekeying a lock in Fairfax typically runs $25 to $45 per cylinder for standard Schlage or Kwikset hardware, and most homes with three exterior doors are done in under 90 minutes. That price is written down before we touch a single tool, and it’s the same number on your invoice. If you’re on Bolinas Road, in the flats near downtown, or up in the hills off Manor Road, we’re already familiar with the kind of locks on your doors. Call (409) 405-4485 and you’ll get a live person, a straight answer, and a firm quote before anything is scheduled.
Why Preston Locksmith & Security Is Fairfax’s Preferred Rekey Locks Company
Fairfax homeowners call us because we do exactly what we say, at the price we quoted, on the day we promised. That’s not a slogan here. It’s how we’ve operated since 2008, and it’s why a rekey call from Fairfax usually turns into a customer who calls back when they need a deadbolt replaced or a commercial storefront rekeyed.
Our technicians, including owner Kevin Yoon, arrive in uniform, background-checked, with their name and photo sent to your phone before they knock. You’ll get a live tracking link with an actual arrival time, not a four-hour window. And every job is covered by the 365-Day Done Right Promise: if it’s not right, we come back and make it right. Fairfax customers get a written guarantee on every rekey, including a free second visit if the new key or cylinder fails within the year.
We answer the phone 24/7 with a live person. No phone tree. No “we’ll call you back.” When you call from Fairfax, you talk to someone who knows the area and can tell you, right then, what your rekey should cost.
Lock Rekey in Fairfax
Lock Rekey in Fairfax means pulling the lock cylinder out of your existing hardware, replacing the internal pins, and cutting a new key so every old key stops working immediately. It’s the faster, less expensive option when your locks are in good shape and you just need to control who has access. We see it most often after a tenant moves out, after a sale closes, or when a homeowner realizes a spare key has been floating around too long. A standard rekey in Fairfax runs $25 to $45 per cylinder, and the per-lock price is confirmed in writing before we start.
Rekey After a Move
Moving into a Fairfax house means you don’t know who still has a key. The previous owner, their neighbor, their dog walker, their contractor. Rekeying every exterior lock on day one is the only way to close that gap completely. We can rekey all your exterior doors to a single new key, so you don’t carry a ring of five.
Losing a Key in Town
Lost a key between the Good Earth and the movie theater? Rekey now, not later. You can’t un-lose a key, and Fairfax is a small enough town that a lost key with any identifying tag is a real risk. Call us, and we’ll have you back on one new key before dinner.
Locksmith Rekey in Fairfax
Locksmith Rekey in Fairfax involves a trained tech, usually at your door within 60 to 90 minutes of your call, pulling each lock cylinder, re-pinning it to match a new key, and testing it in place. The job typically costs $25 to $45 per cylinder for standard residential hardware, but on older Fairfax homes with painted mortise locks, we ask the right questions up front so the number we quote is the number you pay. No arrival surcharge, no upsell on the doorstep.
Rekey vs. Replace
If your lock body is worn, the internal pins are chewed up, or the cylinder won’t hold a key, rekeying won’t fix the underlying problem. Fairfax’s older homes often have original mortise bodies that have been painted over repeatedly. We’ll tell you honestly whether rekeying makes sense or whether a cylinder or full lock replacement is the smarter spend. That conversation happens before we start, not after we’ve opened the door panel.
One Key for Everything
Many Fairfax homes have a mix of Kwikset on the front door, Schlage on the back, and something else on the garage. We can rekey most of those to a single new key, provided the hardware supports the same keyway. We’ll tell you what’s possible and what isn’t before you commit.
Trusted Brands We Service in Fairfax
Our Fairfax rekey calls run heavily toward Schlage and Kwikset on residential doors, with Medeco and Yale showing up on small commercial storefronts and professional offices. We carry pins, springs, and cylinder parts for all four on our service vehicles, so we’re not making a parts run mid-job. Whether it’s the original 1920s mortise lock on a Bolinas Road bungalow or a modern Kwikset deadbolt on a 1970s ranch near Manor, we have the right tools and parts to rekey it correctly the first time.
Common Rekey Locks Problems We See in Fairfax Homes
- Painted-over mortise locks on prewar bungalows. Fairfax’s 1920s redwood bungalows often still have original mortise lock bodies that have been painted over through decades of quick landlord turnarounds. The cylinder is frozen in the trim, and a rekey means carefully freeing it without snapping the trim plate.
- Mismatched locks from past DIY “fixes.” We see doors where the previous owner rekeyed one lock, left two on the old key, and called it done. The result is a front door that takes one key while the back and garage take another. Rekeying everything at once solves it.
- Worn pin stacks that no longer hold a new key smoothly. Some homes call us thinking they need a simple rekey when the real issue is a cylinder so worn the pins are rounded over. A fresh rekey into a bad cylinder is wasted money. We quote both options before dispatch so there’s no doorstep surprise.
- Garage-sale or estate-sale purchases with unknown key copies. After an estate sale on a Fairfax home, no one knows how many keys are floating around. Rekeying before move-in is the standard call, and we’re happy to do every exterior door plus the garage in one visit.
Pricing for Rekey Locks in Fairfax, CA
A standard residential rekey in Fairfax costs $25 to $45 per cylinder, depending on whether it’s a basic Schlage or Kwikset pin tumbler or a high-security Medeco or Yale cylinder. Most Fairfax homes have three to four exterior cylinders, so a typical whole-house rekey lands between $75 and $180 before any new keys are cut. Keys are $5 to $10 apiece. If one of your locks needs a new cylinder instead of just re-pinning, we tell you that exact cost in writing before we touch it. The price we quote on the phone is the price on your invoice, period. Call (409) 405-4485 for a free, itemized estimate. No call-out surcharge, no “it was more work than expected” add-on.

FAQs About Rekey Locks in Fairfax
Yes, we rekey painted-over mortise locks regularly on Fairfax’s older homes. The process involves freeing the cylinder from the trim without damaging the surrounding wood, then re-pinning it to a new key. It takes longer than a modern deadbolt rekey, and we quote it accordingly. Call (409) 405-4485 and describe your lock; we’ll tell you what to expect.
For standard Schlage or Kwikset cylinders on three doors, expect 45 to 90 minutes from arrival to final test. Older mortise locks add 15 to 20 minutes per door. The time is the same whether we’re in downtown Fairfax or up off Bolinas Road, and you’ll get a live arrival time before we head out.
No, a proper rekey never requires a drill. We pull the cylinder, swap the pins, reassemble, and test. If a lock is so corroded or painted that it genuinely can’t be rekeyed, we’ll tell you before we do anything and give you a written price for replacement. We don’t drill as a shortcut.
In most cases, yes. We can rekey most Schlage and Kwikset cylinders to match, though they use different keyways, so the same physical key blank may not work across both. We’ll level with you on what’s compatible before you pay. Call (409) 405-4485 and we’ll tell you if your mix can go to one key.
Before your tech arrives, we send a text with their name, photo, and a live tracking link. Kevin Yoon and every Preston technician arrives in uniform and carries company identification. If anyone shows up claiming to be us without that intro, don’t open the door; call us and we’ll verify. The Relay Visibility Guarantee means you always know who’s coming and when.
