Our Lock Installation & Rekey Services in Mission District
Smart Lock Installation
Smart lock installation in Mission District’s Victorian flats requires more than drilling a new hole and calling it done. Many of these 1890s-1920s wood frames can’t accept standard modern bore sizes without compromising structural integrity. We retrofit Schlage Encode and Yale Assure locks onto existing mortise preparations using custom strike adapters, or we install fresh smart hardware on secondary doors where the frame can support it. A typical smart lock installation in Mission District runs $280-$450, including Wi-Fi bridge setup and smartphone pairing. We always check door alignment first, because in this neighborhood a century of settling on clay soils means the frame is often racked, and no smart lock will function properly against a misaligned strike.
Keyless Entry
Keyless entry systems give Mission District landlords and multi-unit owners a practical solution for the constant turnover this rent-controlled market creates. When a decade-long tenant vacates a unit on Treat Avenue or South Van Ness, rekeying a traditional cylinder takes time and repeat visits. A keyless entry system with programmable codes eliminates that cycle. We install keypad and RFID keyless systems from Schlage and Kwikset that integrate with existing mortise locksets where possible, or we replace the entire entry assembly on newer doors. Most Mission District keyless entry installations fall between $220-$390. We program your first codes on-site and show you how to add or delete users without calling us back.
Keypad Lock
Keypad locks bridge old and new in Mission District’s unique housing stock. For the shared vestibule doors common to four-unit Edwardian flats, a weather-resistant keypad lock lets delivery drivers, dog walkers, and temporary guests enter without distributing physical keys that inevitably get lost or copied. We source marine-grade keypad hardware because Mission District’s position, sheltered from the fog but still close enough to the bay to receive salt-laden air, corrodes standard electronics faster than inland locations. A keypad lock installation on a Mission District vestibule door typically costs $190-$340. We seal all penetrations with corrosion-resistant gaskets and recommend annual inspection of the battery compartment.
Biometric Lock
Biometric lock installation in Mission District remains a smaller part of our business, but demand is growing among tech workers in renovated flats and small commercial spaces along Valencia Street. Fingerprint readers from select manufacturers can integrate with smart home systems, though we are candid about limitations: coastal humidity can affect sensor reliability on exterior doors, and the antique door frames in much of 94110 require significant modification. We install biometric hardware only after assessing the specific door, frame, and exposure. When appropriate, biometric installation runs $340-$520 in Mission District.
Key Duplication
Key duplication for Mission District’s antique locks is not a kiosk job. The skeleton-key blanks and mortise cylinder keys for 1910s hardware don’t exist in automated machines. We stock antique-compatible blanks for the most common Mission District locksets, including bit-key and barrel formats, and we can source obscure profiles within 24-48 hours. Standard key duplication for modern Schlage or Kwikset hardware runs $4-$8 per key in our shop. Antique or restricted-profile keys range $12-$35 depending on blank rarity. We recently rekeyed a four-unit Edwardian on Treat Avenue where the landlord needed an emergency turnover rekey after a decade-long tenant vacated. The original mortise locks, corroded by coastal salt air, had seized deadbolts on two units; we installed stainless steel strike plates and Mul-T-Lock cylinders after adjusting the racked door frames, a job that takes double the time of a standard suburban rekey.

Trusted Brands We Service in Mission District
We install and service Schlage, Kwikset, Medeco, and Yale hardware daily in Mission District, and we maintain a local inventory of cylinders, strikes, and adapters specific to the antique formats common in 94110. That stock matters. When your 1920s mortise lock seizes on a Saturday evening, we don’t need to order parts from a warehouse in Chicago. We carry stainless steel strike plates, antique-compatible cylinders, and modern retrofit kits on every truck. For landlords managing multiple Mission District properties, we keep keyway records on file so rekeying after future turnover takes minutes, not days. Fast turnaround isn’t a slogan here. It’s having the right Medeco cylinder in the truck when we pull up to your building on Capp Street.
Common Lock Installation & Rekey Problems We See in Mission District Homes
- Coastal corrosion seizes mortise cylinders. Salt air from the bay penetrates the tight tolerances of antique lock mechanisms, crystallizing on springs and pins until the key jams halfway or snaps off. We disassemble, clean with corrosion inhibitor, and replace brass internals with nickel-silver components where possible.
- Racked frames misalign strikes. A century of settling on San Francisco’s clay soils pushes Mission District door frames out of square. Residents replace the lock twice before realizing the strike plate needs adjustment. We diagnose frame alignment before quoting hardware replacement.
- Salt air degrades vestibule deadbolts. Exposed brass deadbolts on shared entry doors corrode until they freeze in the extended position, preventing the door from closing properly. We upgrade to stainless steel or coated hardware rated for marine exposure.
- Emergency turnover rekeys after rent-controlled vacancies. When a long-term Mission tenant finally vacates, landlords need immediate rekeying for security and legal compliance. We prioritize these calls and maintain master key systems for multi-unit buildings to streamline future turnover.

FAQs - Lock Installation & Rekey in Mission District
The Mission’s microclimate is the warmest and least foggy in San Francisco, but its proximity to the bay still delivers ambient humidity and intermittent salt air that corrodes exposed iron and brass hardware faster than the drier inland valleys or the fog-washed western neighborhoods. Your Victorian flat’s original mortise mechanisms have tight clearances between springs and pins; when salt crystallizes inside, the key jams or the bolt won’t retract. We see this pattern concentrated in 94110’s pre-1930 housing stock. Call (877) 664-8139 for a free inspection and we’ll show you what’s happening inside the cylinder.
Yes, in most cases we can retrofit an antique mortise lockset to accept modern Schlage-profile cylinders using adapter collars and modified faceplates. The original cast-iron case stays in the door, preserving the historic hardware, while the internal cylinder upgrades to current keyway standards. Not every 1910 lockset is a candidate, severe corrosion or cracked cases may require replacement, but we stock the adapters and have done this conversion hundreds of times in Mission District flats. Call (877) 664-8139 and describe your hardware; we can usually tell you over the phone whether your lockset is convertible.
Tenant turnover rekeys in Mission District cost more because they often involve emergency timing, antique hardware, and additional security considerations that don’t apply to a simple residential rekey. After a decade-long rent-controlled tenant vacates, landlords need immediate service for legal and safety reasons, which may trigger after-hours rates. The original mortise locks may be corroded or seized from years of neglect, requiring disassembly and cleaning before rekeying. Finally, many Mission landlords use this moment to upgrade to master key systems or install restricted keyways to prevent unauthorized duplication. A standard suburban rekey takes 20 minutes; a Mission District turnover rekey with frame adjustment and hardware upgrade can take 90 minutes. The price reflects the work. Call (877) 664-8139 for a flat quote on your specific building.
We do, but only after assessing whether the frame can support modern hardware without structural compromise. Many Mission District door frames from the 1890s-1920s are too thin or too racked for standard smart lock bore sizes. When the frame won’t accommodate a full smart lock, we install retrofit adapters that preserve the original mortise mechanism while adding electronic access control, or we recommend smart hardware for secondary doors where the frame is sound. We’ve installed Schlage Encode and Yale Assure units on dozens of Mission District flats, and we’ll tell you honestly if your specific door is a candidate. Call (877) 664-8139 to schedule an evaluation.
Your key sticks because moisture has entered the cylinder and caused the pins to oxidize or the springs to bind, a problem accelerated by Mission District’s salt-laden air even on days when the fog doesn’t reach the neighborhood directly. The corrosion is microscopic at first, just enough to create friction that catches the key at the shear line. Left untreated, the key will eventually snap or the cylinder will seize completely. We clean and lubricate with corrosion-resistant compounds, and we can upgrade to nickel-silver internal components that resist salt air longer than original brass. Call (877) 664-8139 for a same-day fix, estimates are free.
