Fast, Reliable Residential Locksmith Across San Carlos
Residential locksmith work in San Carlos usually means one of two things: you’re locked out and need a door opened now, or you’ve got aging hardware on a mid-century home that needs to be rekeyed, replaced, or reinforced. We handle both. Our Residential Locksmith team arrives in San Carlos with the cylinder formats, backset tools, and strike plates that 1940s-through-1960s ranch homes actually require, which matters more here than in most Peninsula cities. Call (910) 714-4287 and you’ll speak to a live person, not a voicemail tree.
The short version on cost: rekeying a standard knob or deadbolt in San Carlos typically runs $85 – $145 per cylinder. A new deadbolt installation, including boring and jamb reinforcement on an older door, usually lands between $160 – $280. A residential lockout visit runs $95 – $185 depending on time of day and the lock type on the door. Every price goes in writing before we touch a tool.
Why Dunmore Locksmith Is San Carlos’s Preferred Residential Locksmith Company
San Carlos homeowners call us because the work order says one thing and the door says another. A $40 Kwikset from the hardware aisle doesn’t drop into a 1958 mortise pocket. A Wi-Fi deadbolt won’t seat when the frame has shifted and the strike is biting into soft redwood jamb. Our technicians diagnose that before drilling, and the written quote reflects the real job, not a bait price that doubles at the door.
Dunmore Locksmith is the local face of Threshold Group, the network built around one premise: you should know exactly who is coming to your door before you open it. Every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. The badge at the door matches the photo on your phone. If anyone shows up who you weren’t told to expect, that visit is covered at no charge. That’s the Threshold Standard, and it’s stamped on every job we do in San Carlos.
We’ve been doing this under the Threshold Group umbrella since 2007, and San Carlos’s housing stock keeps us honest. The marine-layer fog that rolls up through the Peninsula corridor every morning means north- and west-facing lock cylinders corrode faster here than they do in Redwood City or Menlo Park. We stock the lubricants and replacement cylinders for that specific failure mode, so we’re not improvising when we arrive.

Apartment Locksmith in San Carlos
Apartment locksmith work in San Carlos covers two situations: renters who need a lock change or rekey after a move, and property managers or building owners who need deadbolt replacements, window lock upgrades, or door reinforcement across multiple units. If you’re renting in one of the older apartment buildings off El Camino Real or around Brittan Avenue, your unit likely still carries original passage hardware that hasn’t been rekeyed in years. We rekey those cylinders, or replace them if the plug is too worn to hold a reliable shear line.
Rekeying After a Move
When a new tenant moves in, the old keys are still out there. Rekeying, which means changing the internal pins so your old keys no longer work, runs $85 – $145 per cylinder in San Carlos. That’s the standard fix for a standard pin-tumbler lock, and it takes about 15 minutes per cylinder once we’re on site. We provide the landlord and the tenant a written key schedule so everyone knows exactly how many working keys exist and who holds them.
Deadbolt and Strike Upgrades in Older Units
Original apartment doors from the 1950s and 60s often carry a knob lock only, or a deadbolt that throws but doesn’t fully engage because the strike was installed on a split frame. We inspect the jamb, reinforce the strike area, and install hardware that actually seats. A complete deadbolt install on an older San Carlos apartment door runs $160 – $280, including the boring work and strike reinforcement.
Lost Key Replacement in San Carlos
Lost key replacement in San Carlos usually starts with a question: do you want the same lock to keep working, or do you want the lost key to stop working? If you just need spare keys cut and the lock still functions, that’s a simple duplication job. If you lost a key and you’re not sure who might find it, rekeying the cylinder replaces the internal pins so the lost key turns into a useless piece of brass. In San Carlos, rekeying runs $85 – $145 per cylinder, and it’s the step we recommend after any lost key that carries your address on the ring.
Mortise Cylinder Key Loss
San Carlos’s original ranch homes were hung with mortise locks, and those cylinders require a different key blank than modern Kwikset or Schlage hardware. If your 1950s door still has the original mortise body and you’ve lost the last key, don’t assume it’s a drill job. We rekey or replace the mortise cylinder itself, and in most cases the original mortise body can stay. A mortise cylinder replacement in San Carlos typically runs $110 – $190 parts and labor.
Full Lock Replacement After Key Loss
Sometimes rekeying isn’t enough. If the lost key belonged to a lock that’s already failing, or if you want a different keyway entirely, we’ll replace the hardware. Kwikset and Schlage keyways cover most San Carlos homes, but we also carry Medeco cylinders for homeowners who want key control that can’t be duplicated at a kiosk. A full knob-and-deadbolt replacement on a standard prep runs $140 – $240, and the old key becomes irrelevant because the entire cylinder set changes.
Trusted Brands We Service in San Carlos
We’re factory-authorized to install and service Schlage, Kwikset, Medeco, Yale, and a full range of residential and commercial hardware families. For the mid-century door preps we see all over San Carlos, Schlage and Kwikset cylinder formats cover most retrofit work, and Medeco gives us a high-security option for homeowners who want a restricted keyway. We stock replacement cylinders, strike plates, and backset adapters on the truck, so a San Carlos job doesn’t stall while parts get ordered from a warehouse.
Common Residential Locksmith Problems We See in San Carlos Homes
- Seized exterior cylinders on shaded entries. The marine-layer fog that settles over San Carlos every morning pushes moisture into north- and west-facing locks. Un-lubricated cylinders corrode from the inside until the key binds or snaps in the plug. We replace the cylinder and cut new keys, same visit, usually $110 – $190.
- Retrofitted smart locks that won’t seat. White Oaks ranches and other post-war homes were built around mortise pockets and non-standard door preps, so a modern Wi-Fi deadbolt often throws but doesn’t fully engage the strike. The fix is boring, backset adjustment, or jamb reinforcement before the smart lock gets mounted, which is why San Carlos retrofit jobs run higher than a simple hardware swap in a new build.
- Partially renovated doors with mismatched backsets. When a previous owner hung a new slab on the original frame, the backset measured 2-3/4″ but the new hardware expects 2-3/8″, or the strike plate bites into soft jamb wood. We diagnose that mismatch before installing anything, so the new lock actually aligns.
- Mortise locks on original doors with no deadbolt above. Many 1940s and 50s San Carlos homes still carry a single mortise passage lock, which won’t hold against a determined kick. We install an ANSI Grade 1 deadbolt above it, reinforced at the strike, so the original hardware stays but the door gets real security.

FAQs About Residential Locksmith in San Carlos
Yes, in most cases. The original mortise body on a 1950s San Carlos door can stay in place while we rekey or replace the mortise cylinder itself. Rekeying a mortise cylinder runs $85 – $145; replacing the cylinder runs $110 – $190. The mortise body only needs replacement if the internal mechanism is physically broken, which is rare. Most people assume their old mortise lock can’t be saved because a big-box store tech told them so. That’s usually incorrect. We’ll tell you honestly which side you’re on. Call (910) 714-4287 and describe what you’ve got.
San Carlos sits in the Peninsula’s marine-layer corridor, so fog and elevated humidity settle on north- and west-facing entries year-round. Exterior cylinders that never get lubricated corrode from the inside until the pins bind and keys stop turning. The fix is usually a cylinder replacement and a proper graphite or PTFE lubrication schedule. We can swap the cylinder on the spot so your key works cleanly again. Call (910) 714-4287 and we’ll bring the right cylinder format for your hardware.
Yes, but it takes prep work. The original mortise pocket and passage-set bore on a 1950s White Oaks door almost never matches the backset and bore pattern a modern smart deadbolt expects. We bored and reinforced a White Oaks frame recently where the original Kwikset cylinder had to be rekeyed first for move-in keys, then the jamb got an ANSI Grade 1 strike so the Wi-Fi deadbolt actually seated and threw clean. Budget $160 – $280 for the full retrofit. In White Oaks, a simple drop-in swap rarely exists. Call (910) 714-4287 for an honest quote on your specific door.
Almost never. A mortise lock with a lost key can usually be rekeyed or have its cylinder replaced without drilling the door or destroying the mortise body. Drilling is the last resort on a San Carlos ranch home, not the default. We’ll pick or shim the door open, remove the cylinder, and restore function in one visit. Lockout plus mortise cylinder replacement typically runs $180 – $260 combined. Call (910) 714-4287 and we’ll walk you through what to expect before we touch the door.
We carry Schlage, Kwikset, Medeco, and Yale cylinders and backsets in the formats that match mid-century door preps, so in most cases you don’t have to change brands. The backset on an original San Carlos door is usually 2-3/8″ or 2-5/8″, and we stock both. The one thing to know: if your old door prep is non-standard enough that a modern brand can’t seat properly without heavy modification, replacement hardware may be the cleaner fix, and we’ll tell you that before any work begins. Call (910) 714-4287 for a straight answer on what your door needs.
