Our Lock Installation & Rekey Services in Daly City
Smart Lock Installation
Smart locks are increasingly popular in Daly City’s multi-generational households, where adult children want remote access for aging parents and ADU tenants need keyless entry without the risk of lost keys. We install Wi-Fi and Bluetooth-enabled deadbolts from Schlage and Yale that withstand the salt-fog environment better than budget brands. A typical smart lock installation in Daly City runs $220-$380 including hardware, with integration to existing home automation systems where compatible. We always verify your door thickness and backset measurement first - many Westlake-era doors are thinner than modern standards and require specific models.
Keyless Entry Systems
Keyless entry eliminates the physical key entirely, replacing it with codes, fobs, or smartphone credentials. In Daly City, where coastal moisture degrades keyways and swells wooden frames that bind traditional locks, keyless systems remove a common failure point entirely. We install keypad and touchscreen entry systems for front doors, side entrances, and converted garage units throughout the Westlake and Hillside neighborhoods. Typical keyless entry installation in Daly City costs $180-$320. We rekey or replace any connected secondary doors to work with your new system.
Keypad Lock Installation
Keypad locks remain the most requested keyless option among Daly City homeowners aged 55-75 - familiar technology, no smartphone required, easy to change codes when caregivers or service providers rotate. We install mechanical and electronic keypad deadbolts from Schlage and Kwikset that resist the corrosion that ruins standard keyed hardware in this climate. A keypad lock installation in Daly City typically runs $160-$280. We program your initial codes, demonstrate operation, and leave written instructions.
Biometric Lock Installation
Biometric locks - fingerprint readers - suit Daly City households with large extended families or rental ADUs where key control becomes unwieldy. We install fingerprint-enabled deadbolts that store multiple profiles and operate reliably despite the moisture that fogs cheaper optical sensors. These systems require more precise door prep than standard deadbolts, and we verify your Westlake-era door can accept the hardware before quoting. Biometric installation in Daly City generally runs $280-$420.
Electronic Lock Repair and Replacement
Daly City’s salt air destroys electronic lock components faster than inland cities. Battery compartments corrode. Circuit boards fail. We repair or replace electronic locks from all major brands, and we carry replacement hardware that fits the specific door dimensions common to 1950s-1960s Daly City construction. Electronic lock service calls in Daly City typically run $120-$260 for repair, $200-$380 for full replacement with rekeying.
Key Duplication
We cut keys on-site in Daly City for Schlage, Kwikset, Medeco, Yale, and most other residential keyways. Because so many Westlake homes still run original or early-generation hardware, we stock key blanks that big-box stores no longer carry. Key duplication runs $4-$12 per key depending on blank type. High-security Medeco or Mul-T-Lock keys require authorization and run $18-$35.

We do not install hardware we cannot stand behind for ten years of Daly City weather.
Common Lock Installation & Rekey Problems We See in Daly City Homes
- Salt-fog corrosion seizes deadbolt bolts into their housings. Daly City’s relentless coastal fog - among the densest in the Bay Area - saturates exterior hardware with salt-laden moisture year-round. We regularly find deadbolts frozen solid in Westlake homes where the bolt has rusted to the strike plate or the cylinder pins have corroded into a single mass. Repair is rarely possible; replacement with marine-grade hardware is the lasting fix.
- Swollen wooden door frames prevent proper latch alignment. The near-constant moisture keeps exterior door frames expanded beyond their dry-season dimensions. A lock that operated smoothly in September binds by January. Rekeying alone cannot solve this - we must adjust strike placement or plane the frame edge to restore function.
- Mismatched secondary doors on ADU and garage conversions complicate master-keying. Daly City’s large Filipino-American households have commonly added secondary exterior doors with hardware purchased from different suppliers across decades. A Schlage deadbolt on the front door, a Kwikset knob on the ADU entrance, and a no-name import on the garage conversion cannot be rekeyed to a single master key without replacing non-standard cylinders.
- Identical 1950s hardware fails simultaneously across entire blocks. In the Westlake neighborhoods, so many homes share the same builder-installed lock prep and door thickness that a corrosion-seized Kwikset on one block often signals the same failure is weeks away on a dozen neighboring homes. Experienced local locksmiths keep that specific hardware stocked as a matter of routine.

FAQs - Lock Installation & Rekey in Daly City

Call (833) 294-4584 for an exact quote - estimates are free.
