Fast, Reliable Change Door Locks Across Union City
Changing door locks in Union City usually costs between $95 and $260 per lock, depending on whether we’re swapping in a new Kwikset, Schlage, or higher-security deadbolt. Most lock changes in Union City are completed the same day, often within two hours of your call. If you’ve just moved into a house in Decoto or a condo near the BART station, you don’t actually know how many old keys are floating around out there. Call (910) 714-4287 and we’ll send a named, photo-badged technician to your door.
We work throughout Union City regularly, from the 1960s tract homes south of Alvarado-Niles Road to the newer Transit Village buildings around the BART station. Our Change Door Locks team knows which lock formats each era of Union City construction used, so we arrive with the right hardware on the truck instead of making a second trip.
Why Dunmore Locksmith Is Union City’s Preferred Change Door Locks Company
Union City homeowners call us because we tell them exactly who is coming to their door before they open it. Every technician is background-checked, identity-verified, and sent to you by name and photo before the visit. When the person at your door matches the photo on your phone and shows a photo ID badge, the worry drops away. That’s the Threshold Standard, and it matters a lot in a city where many households include young children, seniors, and people home alone during the day.
Dunmore Locksmith is the Union City member of the Threshold Group, a network of independent local locksmith businesses operating under one standard since 2007. We answer our phones with a live person 24 hours a day, every day of the year. No voicemail. No chatbot. When you call about a lock that won’t turn in Decoto or a deadbolt binding on a foggy winter night near the bay, a real human picks up and schedules your service.
Our work across Union City has taught us the local hardware story chapter and verse. The 1968 Kwikset deadbolt on a Decoto tract home presents a different job than the electronic keypad on a Transit Village unit built in 2019. The 365-Day Done Right Promise backs every job: if it’s not done right, we return at no charge and make it right. Written price before work starts, every time.
Door Lock Change in Union City
A Door Lock Change in Union City means removing the complete lockset from your door and installing a new one, whether that’s a standard deadbolt, a keypad lock, or a high-security cylinder. It’s the right move when a lock is physically worn out, corroded beyond repair, or you’ve lost all copies of the key. In Union City, we most often see this need in homes where the original Kwikset hardware has spent 40-plus years fighting the salt-laden air that drifts inland from San Francisco Bay. A full door lock change in Union City typically runs $120 to $260 per door, hardware included.
Complete Hardware Replacement
When we replace a door lock, the old lock comes out entirely. The new lock gets a fresh cylinder, fresh keys, and fresh installation. We adjust the strike plate so the deadbolt throws cleanly, which matters in Union City because seasonal fog moisture swells door frames and throws off alignment. The job is done when the deadbolt locks and unlocks with one hand.
New Cylinder, Same Door
Sometimes the lockset body is still solid but the cylinder inside is shot. In Union City’s older homes near the bay side, salt corrosion seizes the pins until keys bind and refuse to turn. Swapping in a new cylinder restores smooth operation without replacing the whole lock. It costs less than a full change and gives you brand-new keys that render all old copies useless.
Lock Change in Union City
A Lock Change in Union City is the service you need when you want old keys to stop working immediately. Unlike a rekey, which alters the existing cylinder to accept a new key, a lock change installs new hardware with brand-new pins and tumblers from the start. In a city where many homes were built in the 1960s and 1970s and have never had their locks professionally serviced, a lock change is often the genuine security upgrade a rekey cannot provide. Expect to pay $95 to $220 for a standard lock change in Union City, depending on the hardware grade.
When Rekeying Isn’t Enough
If your deadbolt is a builder-grade Kwikset from the 1970s and the cylinder has been pitted by decades of marine air, rekeying won’t fix the underlying problem. The pins are corroded, the springs are weak, and the whole cylinder should go. A lock change solves this cleanly. You also get a cleaner security story: nobody, including a previous owner or contractor, holds a working key.
Hardware Upgrade During Lock Change
Many Union City homeowners choose to upgrade during a lock change. Instead of replacing one Kwikset with another, they move up to a Schlage B60N ANSI Grade 1 deadbolt, which has a thicker bolt and a tougher cylinder. For multigenerational households where three generations live under one roof, we can set up a master-key system during the change so one key operates every exterior door.
Trusted Brands We Service in Union City
Dunmore Locksmith is factory-authorized to install and service Schlage, Kwikset, Medeco, Abloy, Mul-T-Lock, Yale, Baldwin, and Sargent hardware. For Union City homes, we stock Schlage and Kwikset cylinders on the truck along with a range of deadbolts and keypad locks. That means when we arrive at a Decoto tract home or a Transit Village condo, we have the parts in hand, not on order. If you want a Medeco high-security cylinder or an Abloy system, we source it fast and install it on schedule. For most Union City lock changes, common-brand parts are available same day.
Common Change Door Locks Problems We See in Union City Homes
- Salt-corroded cylinders in Decoto homes. The bay marine layer pushes salt air inland, and the original 1970s Kwikset pin stacks seize until keys bind and refuse to turn. A new key won’t help; the cylinder itself is done.
- Winter deadbolt binding at the strike plate. Fog moisture makes original doors swell every late fall and winter. A new deadbolt that should drop in binds against the strike unless we reset the plate or relieve the frame.
- Contractor master keys still circulating. Many un-rekeyed Decoto homes still carry the original contractor master keying. If you buy one of these houses and only change the knob, the old key still turns the deadbolt.
- Mixed-era hardware in Transit Village units. Newer buildings around the BART station use electronic fobs and keypad access, but some units still have a mechanical lock on the rear door or storage room. Getting them all on one system takes a technician who understands both formats.
Pricing for Change Door Locks in Union City, CA
In Union City, a standard deadbolt change with a Schlage or Kwikset lock runs $120 to $260 per door, including hardware and labor. Rekeying an existing lock runs $65 to $150 per cylinder. A high-security cylinder from Medeco or Abloy starts around $180 and goes up from there. The pattern we see across Union City is honest: older Decoto homes often need cylinder replacement, not just a rekey, because salt air has damaged the internals. You’ll get an itemized written price before work begins, and that’s the price on the invoice. Call (910) 714-4287 for a free estimate. No call-out fee added on arrival.

FAQs About Change Door Locks in Union City
We can usually rekey the lock if the cylinder is still mechanically sound, but in Decoto’s salt-heavy marine air, original 1970s Kwikset cylinders are often corroded internally. If the pins are seized or the springs are shot, rekeying is a waste of money; the cylinder needs replacement. We’ll inspect it in front of you and tell you which way to go. Call (910) 714-4287 and we’ll give you an honest answer before any work starts.
A rekey keeps the existing lock hardware and changes the internal pins so old keys no longer work. A lock change removes the old hardware entirely and installs a brand-new lock. In Union City, rekeying costs $65 to $150 per cylinder, while a full lock change runs $120 to $260 per door. The right choice depends on the age and condition of your hardware, and we’ll show you exactly what we’re seeing.
In Union City, it’s usually the door. Fog moisture makes original frames swell in late fall and winter, and the deadbolt binds against the strike plate even when the lock itself is fine. We reset the strike plate or relieve the frame opening at the same time we service the lock, so the deadbolt throws cleanly all year. Call (910) 714-4287 to have it done right the first time.
Yes, we service electronic access systems in the Transit Village buildings around the Union City BART station, including fob, keypad, and proximity-card entry. A condo lock change there often involves reprogramming rather than picking pins. If you’re unsure whether you’re allowed to change hardware under your HOA’s rules, we’ll help you sort that out too.
Yes, and we do it regularly in Union City, where many single-family homes house three generations under one roof. A master-key system gives each family member a key that works only their door, while one master key operates every door in the house. We can build this into a lock change so you don’t pay twice. Call (910) 714-4287 and we’ll map out the system before you commit to anything.
A Real Job in Decoto
We were called to a 1968 Decoto tract house off Alvarado-Niles where the owner’s builder-grade Kwikset deadbolt had never been rekeyed since the contractor installed it. Our tech ran a non-destructive entry and pulled the cylinder to find the original contractor pins still stamped. Because the cylinder body was pitted from salt air and the door had swollen at the strike plate, we bypassed a simple rekey and installed a Schlage B60N ANSI Grade 1 deadbolt with a fresh cylinder, then adjusted the strike for the warped frame. The homeowner walked away with real key control instead of a false sense of security.
That’s what a lock change in Union City should look like. Not a quick swap and a handshake, but an honest assessment of what your house actually needs. If the cylinder is fine, we’ll rekey it and save you money. If the salt air has eaten it, we’ll tell you that too.
