Fast, Reliable Residential Locksmith Across Los Gatos
Locked out on a steep Los Gatos hillside street? Need a deadbolt that actually fits a 1920s mortise door instead of the big-box hardware that never latches clean? Our Residential Locksmith team gets to Los Gatos fast, quotes a written price before a single tool leaves the bag, and shows up with the right hardware for your specific door. Call (409) 405-4485 and a live person answers, 24/7. No voicemail trees. No four-hour windows.
Why Preston Locksmith & Security Is Los Gatos’s Preferred Residential Locksmith Company
Los Gatos homeowners have a particular problem: their doors are not alike. A 1910 Almond Grove bungalow has original mortise locks and handmade strikes. A 2019 hilltop build near Blossom Hill has a smart lock and an ANSI-rated steel door. We carry both pin-and-tumbler kits and mortise tooling on every truck we roll into Los Gatos because we know the difference matters. A generic crew that only stocks Schlage and Kwikset cylinders will drill or replace where we can rekey and preserve.
Every job gets The Relay Visibility Guarantee: a live trackable arrival time, before-and-after photos, and a written price confirmed before dispatching. The tech at your door is background-checked, uniformed, and named on the booking. You are not getting an anonymous subcontractor with a drill and a vague hourly rate. Kevin Yoon runs the shop and stands behind the 365-Day Done Right Promise: if it’s not done right, we make it right, with a written guarantee stamped on every repair.
Locksmith Key Replacement in Los Gatos
Locksmith Key Replacement in Los Gatos usually means one of two things: cutting a new key from a worn original, or rekeying the lock cylinder so old keys stop working. A standard house key duplicate runs $5 to $12 per key. Rekeying a typical Schlage or Kwikset deadbolt runs $18 to $35 per cylinder, written price confirmed before we start. If the original mortise cylinder in an older downtown or Almond Grove home is involved, expect $30 to $50 per cylinder because the pinning is finer and the cylinder often needs cleaning and lubrication before new pins seat correctly.
The work itself is quick. Rekeying means swapping the internal pins so the old key no longer turns. We do it on site, usually in 20 to 40 minutes for a single door. You keep your existing hardware; you’re not paying for new deadbolts you don’t need.
Worn Or Broken Key Replacement
Keys wear down over years of daily use. The edges round off, the key sticks, and eventually it won’t turn at all. If you’ve been jiggling a key in a Los Gatos front door for months, that’s the sign. We cut new keys from code or from the lock itself, not from the worn key, so the replacement actually works.
Mortise Cylinder Rekey Without Replacing Hardware
Older Los Gatos homes have mortise locks that are no longer manufactured. Replacing them means sourcing old hardware or retrofitting the door, which is expensive and often unnecessary. In most cases, we rekey the existing mortise cylinder in place, preserving the original hardware and keeping the door looking as it should. The old keys are dead, the new keys work, and the door never lost its character.
Smart Lock Installation in Los Gatos
Smart Lock Installation in Los Gatos is common on newer builds and increasingly requested for older homes where homeowners want keypad or app entry without replacing every door. A basic smart lock install runs $150 to $250 including hardware and labor. If the door is a prewar mortise door, the price can run $250 to $350 because the mortise pocket has to be modified or the lock has to be fitted to the existing deadbolt prep. We always verify strike alignment and door fit before we call the job done, because a smart lock that does not latch clean is a false sense of security.
We regularly install smart locks that work with the deadbolt you already have rather than selling you a full hardware swap. If your existing Schlage deadbolt is in good shape, there’s a good chance we can fit a smart module over it and keep the hardware.
Keypad And App-Controlled Entry on Existing Doors
Most Los Gatos homeowners ask for a keypad deadbolt or a retrofit smart module. We install brands like Schlage Encode, Kwikset Halo, and Yale Assure. Before quoting, we check the bore size, the backset, and the door thickness. Some older Los Gatos doors are thinner than modern standard, and that changes what fits.
Why We Check Strike Alignment on Every Smart Lock Install
Smart locks have a motorized bolt. If the strike is even slightly misaligned, the motor binds, the battery drains fast, and the lock fails in months. On older Los Gatos doors, the strike plates have shifted over decades. We align or replace the strike as part of the install, and we test the lock through a full cycle before we leave.
Trusted Brands We Service in Los Gatos
We stock and service Schlage, Kwikset, and Medeco hardware for Los Gatos residential work. That covers the everyday deadbolts on most California homes and the high-security cylinders some hillside homeowners prefer. We carry common parts for these brands on the truck, so a rekey or cylinder swap rarely involves a second visit. You do not need to order parts online and wait. We bring the pins, cylinders, and tailpieces for these brands when we roll into Los Gatos.
Common Residential Locksmith Problems We See in Los Gatos Homes
- Original mortise locks on older downtown and Almond Grove homes. These locks were built before modern ANSI deadbolt standards, and a new deadbolt often won’t seat correctly without a cylinder-and-strike retrofit. We carry the tooling to do that retrofit non-destructively.
- Drilled-out high-security cylinders. Some dispatch-first shops reach for a drill too fast. We attempt non-destructive entry on Medeco, Mul-T-Lock, and Abloy cylinders before drilling, because those cylinders are expensive to replace and most of them can be picked or bypassed by someone who actually trains on them.
- Door-fit failures on newly installed deadbolts. We regularly see new deadbolts hung on older Los Gatos doors without strike alignment. The door never latches clean, the deadbolt never fully throws, and the homeowner calls us to fix a problem the last tech created.
- Keypad deadbolts draining batteries in weeks instead of months. This is almost always misalignment or a sloppy install, not a bad lock. We check the strike, the bolt throw, and the door sag before we blame the hardware.

FAQs About Residential Locksmith in Los Gatos
Yes. In most Los Gatos homes with original mortise locks, we rekey the existing cylinder in place for $30 to $50 per cylinder. The old keys stop working, you get new keys, and the original hardware stays on the door. Rekeying takes 20 to 40 minutes per lock. Call (409) 405-4485 and we’ll confirm the written price before dispatch.
A standard residential lockout in Los Gatos runs $75 to $150. You know the number before the tech is dispatched, because we quote by phone and put the price in writing before anyone leaves the shop.

Every Preston Locksmith & Security tech is background-checked, arrives in a branded uniform, and is named on your booking confirmation.

If it doesn’t, do not open the door. We never send anonymous subcontractors.
We install smart locks on both. Older Los Gatos doors, especially the prewar mortise doors downtown and in Almond Grove, often need a cylinder-and-strike retrofit before a smart deadbolt will work properly. We quote that work honestly, and in many cases we can fit a smart module to your existing Schlage deadbolt rather than selling you a full hardware set. The install includes strike alignment verification and a full cycle test before we leave.
We carry and service Schlage, Kwikset, and Medeco hardware for Los Gatos homes, along with Abloy, Mul-T-Lock, Baldwin, Yale, and Sargent for specialized residential and high-security work. For most Los Gatos households, that means a standard Schlage or Kwikset deadbolt rekey or replacement is done on the spot. Call (409) 405-4485 and tell us what’s on your door; we’ll tell you the brand and the price before we send anyone.
