Fast, Reliable Lock Installation & Rekey Across Union City
Lock installation and rekeying in Union City runs $120-$380 for most residential jobs, with same-day scheduling available throughout the 94587 zip code. Our Lock Installation & Rekey crew knows the local rules: we match HOA-approved finishes, handle field-mortised strike plates for earthquake-shifted frames, and quote a flat price before the truck ever leaves our shop.
We’ve worked Union City’s neighborhoods for decades, from the original Decoto core to the newer townhome clusters near the BART station. The city sits on the Hayward Fault, and that seismic reality shapes every lock job we do here. A standard hardware swap that works in Fremont or Newark often fails in Union City without proper frame assessment. We plan for that. Call (877) 664-8139 and we’ll give you a real price on the phone.
Why Strongbox Lock & Safe Co. Is Union City’s Preferred Lock Installation & Rekey Company
Union City homeowners have called us for over 42 years because we show up when we say we will and we stand behind the work. Our 90-Day Done Right Promise means if something isn’t right, we come back. No paperwork to file, no argument to win.
Our technicians are background-checked, uniformed, and present ID at your door on every visit. The person who opens your locks should be the most verifiable person you’ve ever hired. We quote a flat price before any work begins, the direct answer to the bait-and-switch pricing that has burned too many Union City residents.
A live person answers every call, 24/7, including nights, weekends, and holidays. No voicemail trees, no callback queues. We recently rekeyed a 1970s tract home on Dyer Street in Decoto where three deadbolts had seized after a series of minor tremors. Our crew installed a Schlage B60N with a field-modified strike plate to match the existing non-standard offset, restoring smooth operation without triggering an HOA review. That’s the kind of local knowledge that saves Union City homeowners time, money, and a second trip.
Our Lock Installation & Rekey Services in Union City
Smart Lock Installation
Smart lock installation in Union City typically costs $280-$520, including the device and labor. Many of the newer townhome and condo clusters near the Union City BART station have HOA-managed access systems from the 1990s-2000s that are now aging and parts-scarce. We install current-generation Schlage Encode and Yale Assure locks that integrate with existing WiFi and meet most HOA quiet-operation requirements. Before we drill, we verify your association’s approved hardware list to avoid violation notices.
Keyless Entry
Keyless entry systems run $220-$480 installed in Union City, depending on whether you need a simple keypad or a full electronic deadbolt with remote access. Homes on the west side of Union City, near the Don Edwards San Francisco Bay National Wildlife Refuge, face persistent salt-laden marine air that corrodes exterior hardware faster than inland. We specify marine-grade finishes and corrosion-resistant cylinders for those properties. If your HOA requires oil-rubbed bronze and you want satin nickel, we’ll tell you before you buy.
Keypad Lock
Keypad lock installation in Union City generally falls between $180-$340. These are popular with families in the older tract homes off Decoto Road and Alvarado Boulevard, where multiple generations share a house and nobody wants to manage spare keys. We program user codes on-site and show you how to add or delete them. For Union City’s 1960s-1980s housing stock, we always check the door frame for seismic shift before mounting, a step cut-rate operators skip.
Biometric Lock
Biometric lock installation in Union City starts around $340 and can reach $620 for multi-factor units with fingerprint plus keypad backup. These see growing interest in the newer developments near Station Square, where tech commuters want home access that matches their workplace security standards. We source Medeco and Mul-T-Lock biometric hardware with ANSI Grade 1 ratings, and we verify HOA approval before installation.
Electronic Lock
Electronic lock replacement and rekeying in Union City costs $160-$380 for most residential applications. The bulk of Union City’s housing stock still runs original builder-grade deadbolts from the 1970s and 1980s. Those old cylinders seize, wobble, or fail to retract. We replace them with modern electronic equivalents that fit the same bore holes but add programmable access and audit trails.
Key Duplication
Key duplication in Union City runs $8-$24 per key for standard residential blanks, with restricted high-security keys like Medeco or Mul-T-Lock running higher due to authorization requirements. We cut on-site while you wait, and we can duplicate most HOA master key systems for approved residents.

Trusted Brands We Service in Union City
We install and service Schlage, Kwikset, and Yale hardware from stock carried on every Union City service vehicle. That means no waiting for parts from a warehouse across the Bay. A Schlage B60N deadbolt, a Kwikset SmartKey cylinder, or a Yale electronic lock, we typically have it on the truck. For high-security applications, we order Medeco and Mul-T-Lock with proper key control documentation. The right lock goes on the right door, not just what’s available.
Common Lock Installation & Rekey Problems We See in Union City Homes
- Seismic frame shift in Decoto. Decades of Hayward Fault microseismic activity have shifted door frames throughout the Decoto neighborhood, creating non-standard strike-plate offsets. Installing a new deadbolt without a field-mortised strike plate leads to misalignment and door binding within weeks.
- Salt-air corrosion on the west side. Homes and apartment complexes near the bay and the wildlife refuge face persistent marine air that accelerates corrosion and jamming of exterior lock cylinders and strike plates faster than in inland East Bay cities like Livermore or Pleasanton.
- HOA violation notices for non-approved finishes. Using non-ARB-approved door hardware colors, such as satin nickel in a community that requires oil-rubbed bronze, results in homeowner violation notices and costly rework.
- Noise complaints in quiet-operation zones. Replacing a lock with a loud or clunky mechanism near HOA common areas causes noise complaints and rework orders, particularly in the denser townhome clusters near the BART station.

FAQs - Lock Installation & Rekey in Union City
Yes, most Union City condos and townhomes require Architectural Review Board approval before exterior hardware changes. We verify your association’s approved device list, finish colors, and quiet-operation requirements before we install anything. Call (877) 664-8139 and we’ll walk you through the approval checklist during your free estimate.
Yes, and we will also assess whether your strike plate needs field-mortising to match the new frame position. In Union City’s Decoto neighborhood, this is routine work for us. A straight rekey without addressing frame shift often leads to a seized deadbolt within weeks. We handle both the rekey and the mechanical adjustment in one visit.
Salt-laden marine air from the bay and the Don Edwards San Francisco Bay National Wildlife Refuge accelerates corrosion on exterior hardware. Standard finishes that hold up fine in inland East Bay cities fail faster here. We specify marine-grade or PVD finishes for west-side Union City properties, which extends cylinder life significantly.
Yes, we stock keyless entry and electronic locks in multiple finishes including oil-rubbed bronze, satin nickel, polished brass, and matte black. We verify your HOA’s approved palette before quoting, so you get modern access control without a violation notice. The price quoted on the phone includes the finish you need.
Seized deadbolts from decades of frame shift combined with original builder-grade hardware. The 1960s-1980s tract homes throughout Union City, particularly in Decoto and the Alvarado corridor, still run their original Kwikset or Weiser cylinders. After enough tremors, the bolt no longer aligns with the strike plate, and forcing it snaps the internal mechanism. We replace with Grade 2 or Grade 1 hardware and custom-fit the strike plate to the actual frame position.
