Why Preston Locksmith & Security Is Fairfax’s Preferred Residential Locksmith Company
Fairfax is a small town, and word travels fast on the streets off Sir Francis Drake Boulevard. Homeowners here talk. They know which contractors show up when they say they will, and which ones send a different tech than the one on the van. Our reputation in Fairfax comes down to one thing: consistency. Kevin Yoon runs this operation with a simple standard. The tech who arrives is background-checked, wears a Preston uniform, and matches the name and photo you received in your dispatch confirmation. No mystery subcontractors.
Response time to Fairfax is typically 35 to 45 minutes from the moment our dispatcher confirms your address. That gets us from the Bay Area dispatch office over White Hill and into the flats, Deer Park, or up toward Bolinas Road without wasting a minute. Fairfax’s narrow lanes and tight driveways on streets like Cascade Drive or Scenic Road don’t slow down a tech who has already worked a dozen homes in the same neighborhood.
We’re part of the Relay Home Co. family, founded in 2008, and every location is independently owned and operated. What that means for you: the accountability is local. You’re not calling a national franchise number. You’re calling a crew that knows Fairfax doors, Fairfax hardware, and Fairfax’s particular lock problems.
House Key Locksmith in Fairfax
A House Key Locksmith call in Fairfax usually means one of three things: you need new keys cut, you need existing locks rekeyed so old keys stop working, or you need a lock replaced because the key is bent, broken, or won’t turn. Most Fairfax homes are working with older Schlage or Kwikset pin-and-tumbler cylinders, which are completely serviceable if you maintain them. Rekeying a standard cylinder in Fairfax runs $85 – $150 per lock, written price confirmed before we start. Cutting a new key from an existing one costs $15 – $35.
Rekeying Without Replacing Hardware
Rekeying means swapping the internal pins inside the cylinder so the old key no longer turns the plug. The lock stays on the door. This is the right move after buying a Fairfax home, after a tenant moves out, or after a key goes missing on the Bolinas Road trailhead. If your door carries the original locks from a 1960s or 1970s ranch, we almost always recommend rekeying over replacement unless the cylinder is corroded internally.
Key Cutting and Duplication
Standard house keys for Kwikset or Schlage locks cut on-site in about five minutes. We can also cut restricted keys from Medeco or Mul-T-Lock systems if your Fairfax property carries high-security cylinders. Mark any spares clearly; Fairfax’s wet winter months cause cheap nickel-plated blanks to oxidize faster if stored in a damp garage or shed.
House Lockout in Fairfax
A House Lockout in Fairfax means you’re standing outside with no way in, often on a sloped front step or a path slick from morning fog off White Hill. We get it. Our typical arrival is 35 to 45 minutes, and a daytime lockout on a standard deadbolt costs $95 – $165 with no added call-out fee when you confirm the price before dispatch. That number includes non-destructive entry attempts first, meaning we try opening the door without drilling whenever the lock allows it.
Non-Destructive Entry First
Most Fairfax lockouts involve a pin-and-tumbler deadbolt or knob lock that can be opened with lock picks and a tension wrench, not a drill. Non-destructive entry is faster, quieter, and leaves your hardware intact. We only drill when the cylinder is frozen, corroded, or the key is broken off inside. If a drill is needed, we tell you the replacement cost before the bit touches metal.
Lock Replacement After Lockout
If we can’t save the cylinder, or you’d prefer new hardware after an attempted break-in on a lower Deer Park street, we carry Schlage, Kwikset, and Yale deadbolts in the van. A new ANSI Grade 1 deadbolt installed in Fairfax runs $190 – $320 including hardware and labor. You get the exact figure before we begin, and the written price is the invoice price.
Trusted Brands We Service in Fairfax
Fairfax homes run on a mix of hardware generations, from 1950s Kwikset knobs to newer Schlage deadbolts and the occasional Medeco high-security cylinder on a gate or workshop. Our techs are factory-trained on Schlage, Kwikset, and Medeco, and we stock common pin kits, tailpieces, and cylinder parts in the van. That means we can usually rekey a standard Fairfax home without a second trip. Kevin Yoon’s rule is simple: bring the parts the job probably needs, not just the ones you think you’ll sell.
Common Residential Locksmith Problems We See in Fairfax Homes
- Corroded cylinders after wet winters. Fairfax gets real rain, and locks on exposed doors along Bolinas Road or up in the hills trap moisture. Older Kwikset cylinders especially seize up by February, and we see a spike in rekey and replacement calls every spring.
- Swollen doors that won’t latch. Pre-war bungalows and 1960s ranches in Fairfax often have solid wood doors that swell with humidity. The deadbolt throws fine but the strike plate no longer lines up, so the door pops open. We realign the strike or plane the door edge as part of the repair.
- Worn original hardware from the 1950s through 1970s. A lot of Fairfax homes still carry the original Schlage or Kwikset pin-and-tumbler locks from construction. They can last decades, but the springs fatigue and the pins lose their crisp feel. Rekeying often restores function without replacing the visible hardware.
- Narrow street parking and tight driveways. Fairfax streets like Scenic Road and Cascade Drive leave little room to maneuver. Our techs know where to park without blocking a neighbor, and we carry compact gear that doesn’t need a garage-sized staging area.

FAQs About Residential Locksmith in Fairfax
Before any tech is dispatched to a Fairfax home, you receive the tech’s name and photo by text, along with a live trackable arrival time through The Relay Visibility Guarantee. The person who arrives will match that photo, wear a Preston Locksmith & Security uniform, and drive a marked van. You can verify the name at the door, and the tech will know the work order details from your call. Call (409) 405-4485 and ask questions before dispatch; a live person answers.
Yes, in most cases we can rekey your original Kwikset pin-and-tumbler cylinders for $85 – $150 per lock. The lock stays on the door, and we swap the internal pins so the old keys stop working. We check cylinder wear, keyway condition, and spring tension as part of the rekey. If the cylinder is too corroded or the springs are shot, we’ll tell you and give a straight replacement quote before touching anything. The written quote comes first, always.
No. Most lockouts in Fairfax are solved with non-destructive entry using picks and tension tools, and that is our first approach unless the lock is frozen, broken, or otherwise mechanical. We only drill when there is no other safe way in, and if drilling is required we quote the replacement part cost before making the cut. A daytime lockout with non-destructive entry runs $95 – $165. Call (409) 405-4485 from your front step and we’ll get a tech rolling to your exact spot.
Yes. If you want a new Schlage or Kwikset deadbolt matched to your existing knob or lever, we can build the new cylinder to match your current key, so one key operates both. We do this on 1960s and 1970s Fairfax ranches all the time, where the front door carries one brand and the back door another. The new deadbolt install runs $190 – $320, and keying it to match adds no charge when we’re already working on the door.
Most jobs in Fairfax take 30 to 90 minutes on site. A single lock rekey is about 20 minutes. A deadbolt replacement is 45 to 60 minutes including cleanup and testing. A lockout with non-destructive entry is often 10 to 15 minutes once the tech arrives. Travel time to Fairfax is 35 to 45 minutes from dispatch. We send before-and-after photos of every completed job, and you get a digital invoice with a pay link before we leave. For an exact timeline on your lock, call (409) 405-4485.
