Fast, Reliable Change Door Locks Across San Jose
Changing your door locks in San Jose typically costs $95 – $320 depending on the hardware, and most residential jobs are completed the same day. If you’ve lost a key, bought a home, or had a tenant move out, we can rekey or replace your locks and make every old key useless. Call (910) 714-4287 for a written quote before anyone rolls a truck. We know the difference between a Willow Glen bungalow with a narrow door prep and an Alum Rock ranch with three outbuildings, and we price the job accordingly.
Why Dunmore Locksmith Is San Jose’s Preferred Change Door Locks Company
San Jose homeowners call us because we tell them exactly who is coming to the door before they open it. Every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. That’s the Threshold Standard, and it means you never open your door to a stranger in a rental van who could be anyone. Perry Osgood, our owner, built Dunmore around a simple old word: Dunmore comes from old words for a great fort, a stronghold built to keep what is inside safe. That’s the standard for every lock change we do in San Jose.
The price you get on the phone is the price on the invoice. We put it in writing before any work starts, every single time. No one in San Jose should have to stand at their own front door arguing with a technician about a bill that ballooned. Our reviews from San Jose customers in Berryessa, Cambrian, and Naglee Park consistently mention two things: named technicians who showed ID at the door, and a final total that matched the phone quote.
Change Lock Cylinder in San Jose
Change Lock Cylinder is the job most San Jose homeowners actually need, even when they think they need a whole new lock. The cylinder is the part your key slides into. When we change it, the old keys stop working and you get a fresh set, usually in under an hour. On San Jose’s 1950s and 60s tract homes, many original cylinders are worn to the point that any similar key jiggles the pins, which means a stranger may already have a key that opens your door.
Rekeying a Standard Knob or Deadbolt
Rekeying a standard knob or deadbolt in San Jose runs $35 – $50 per cylinder. We remove the cylinder, swap the internal pins, and cut new keys. Your old keys become useless instantly. This is the right call when a key goes missing at a North San Jose tech campus shuttle stop, or when a roommate moves out of a house near San Jose State and you don’t want to replace every lock.
High-Security Cylinder Changes
For Medeco or Mul-T-Lock cylinders on a Willow Glen cottage or a Naglee Park Arts and Crafts home, expect $75 – $150 per cylinder. These cylinders require restricted key blanks that can’t be copied at the hardware counter. That matters in San Jose, where dated builder-grade locks on mid-century homes are common and a high-security cylinder is a genuinely meaningful upgrade, not an upsell.
Door Lock Installation in San Jose
Door Lock Installation in San Jose means replacing the full lock body, not just the internal cylinder. Most San Jose ranch homes built between 1955 and 1975 still have single-cylinder deadbolts with hollow-core doors. A full replacement with a new Schlage or Kwikset deadbolt and reinforced strike plate typically runs $120 – $220 per door, hardware included. We do this constantly on streets off Capitol Expressway and Hillsdale Avenue, where the original hardware is now 60 years old.
Deadbolt Replacement on Mid-Century Doors
Many doors in Cambrian and Berryessa were bored for a smaller-diameter deadbolt than what’s standard today. We carry adapter kits so a modern ANSI Grade 1 deadbolt fits a 1958 door without butchering the frame. The job usually takes about 45 minutes per door.
Smart Lock Installation
San Jose has one of the highest smart-lock adoption rates in the country because this is Silicon Valley. Installing a Schlage Encode or Yale Assure with Wi-Fi and Apple HomeKit integration runs $180 – $260 including hardware configuration. We also program Z-Wave and Zigbee models for existing hub-based setups. The hardware is genuine and factory-authorized, not third-party knockoff stock.
Trusted Brands We Service in San Jose
We are factory-authorized on Schlage, Kwikset, and Yale hardware, and we stock parts at our San Francisco Bay Area coordination office so San Jose appointments don’t get delayed by a two-day parts wait. That matters when a Cambrian homeowner needs a Schlage B60 deadbolt installed same-day, or when a Naglee Park landlord wants Yale Assure keypads on three doors before a new tenant moves in. Our technicians carry common strike plates, tailpieces, and cylinders for these lines in the van.
Common Change Door Locks Problems We See in San Jose Homes
- Thermal swing deadbolt binding: San Jose’s dry summer pattern of low-90s afternoons and 50-degree nights makes wooden door frames expand and contract daily. By July, deadbolts on the east and south sides pull out of strike-plate alignment and the key won’t turn. We realign and reinstall the strike plate, or replace the frame screws with 3-inch galvanized screws that hold the plate to the stud.
- Forgotten outbuilding cylinders: On acreage properties around San Jose’s edges, a homeowner rekeys the house but forgets the detached workshop or side gate. That old key still opens a building full of tools. We key every cylinder alike in one visit, including gate locks and workshop deadbolts.
- Builder-grade hollow-core doors: Many 1950s tracts off Alum Rock and White Road have hollow-core doors with a thin veneer. A deadbolt is only as strong as the door it sits in. We often recommend a wrap-around reinforcement plate or a solid-core door upgrade for the side garage entrance.
- Worn pin-tumbler cylinders after tenant turnover: San Jose’s renter-heavy neighborhoods like the area around San Jose State and Japantown see constant move-out rekeys. A cylinder with 15 years of daily use often gets sloppy enough that a worn key from a previous tenant still catches. A cylinder change, not just a rekey, is the correct fix.

FAQs About Change Door Locks in San Jose
Yes, and we do this regularly. One technician can rekey or replace the cylinders on a main house, a detached workshop, and a side gate in a single two-hour service drive. Out on a Cambrian ranch recently, a homeowner had exactly this setup. Our tech found the original builder-grade deadbolt had pulled out of alignment from years of thermal shifting, so he replaced it with an ANSI Grade 1 deadbolt, rekeyed the workshop’s pin-and-tumbler cylinder, and matched the gate lock, all in one visit so the owner wasn’t paying for three separate trips. Call (910) 714-4287 and tell us how many cylinders you have. We’ll quote the whole job before dispatch.
That’s the daily thermal swing. San Jose’s dry summers push afternoon temps into the low-to-mid 90s while nights drop into the 50s. The wooden door frame on a mid-century ranch absorbs moisture and heat during the day and contracts at night. Over weeks, this pulls the deadbolt out of alignment with the strike plate, and by mid-summer the bolt binds. We fix it by realigning the strike plate and replacing the short frame screws with long screws that anchor into the stud. It’s a 30-minute job and it doesn’t come back next summer.
Yes. We can install a Schlage Encode keypad on the front door and key the detached workshop to a matching physical key that also fits the deadbolt on the house. That way the keypad is the daily entry, but your keychain key still opens the workshop and the house deadbolt if the battery dies or the Wi-Fi is down. The cost depends on the number of cylinders, but a keypad plus two matching cylinders in San Jose typically runs $320 – $450 installed.
That depends on what’s failing. If the lock still turns smoothly and the only problem is key control (old copies floating around), a rekey for $35 – $50 per cylinder solves it. If the deadbolt binds in summer, the strike plate has shifted, or the lock is sloppy, a full replacement with a reinforced strike plate runs $120 – $220 per door. We’ll tell you which one you actually need, not whichever one costs more.
Most San Jose appointments, including far east side areas past Alum Rock or the south side off Blossom Hill, are reached in under 60 minutes from the time you call. We coordinate dispatch from our Bay Area office and have crews staged around the city. You’ll get the technician’s name and photo before they arrive, so you know who to expect at the gate.
