San Marino is a city of large period-revival estates, and a smart lock here is rarely a simple swap. Many homes from the 1920s and 1930s have solid-wood doors, original mortise hardware, and vintage brass that owners want to keep. Our job is to add keyless convenience and tighter control over who has access without making a Spanish Colonial, Tudor or Georgian entry look like an electronics aisle.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner David Shar's team brings that experience to every installation. We install and configure smart deadbolts, keypad locks and keyless entry systems, then walk you through how they work, who can open them, and what to do if a battery runs low or a phone is lost.

We are a mobile service only. There is no storefront to visit. We come to you at any hour, assess the door, and explain which options suit it, including when a smart lock is not the best choice for a particular door and a high-security cylinder or a more traditional upgrade makes more sense.

How it works in San Marino

  1. 1

    Talk through your goals

    Call (323) 997-8867 and tell us what you want: keypad entry, app control, temporary codes for staff or contractors, or a discreet system that suits a period home. We ask about the door type and any existing hardware.

  2. 2

    Assess the door and hardware

    On site, we look at the door thickness, the condition of the wood, the existing lock prep, and whether the door has mortise hardware, a bored deadbolt, or a gate latch. Older doors often need careful evaluation before anything is drilled.

  3. 3

    Recommend the right option

    We explain realistic choices, from a retrofit smart deadbolt that keeps your existing handle set to a keypad or keyless unit on a side or garden door. If original mortise hardware is worth preserving, we say so and plan around it.

  4. 4

    Install with care for the finish

    We mount the lock, align the bolt and strike, and protect the wood and brass as we work. The goal is clean, smooth operation without unnecessary modification of a vintage door.

  5. 5

    Set up codes, apps and access

    We configure user codes, connect the app if you want one, set up temporary or scheduled access where the lock supports it, and test every function with you present.

  6. 6

    Handoff and troubleshooting guidance

    We show you how to change batteries, use the mechanical key override if there is one, and reset codes after a staff change. If an existing smart lock is misbehaving, we troubleshoot it as part of the visit.

What affects the price

  • The type of lock chosen, since a basic keypad deadbolt differs from a connected smart lock with app features and integrations.
  • Door condition and construction, including solid wood, thick period doors, or existing mortise preparation that affects how the lock must be fitted.
  • The number of doors and gates being converted, and whether you want them all on one coordinated access system.
  • Whether a high-security cylinder, rekey or safe-grade deadbolt upgrade is added alongside the smart lock.
  • Time of day, since after-hours and emergency visits are handled differently from scheduled appointments.
  • Setup complexity, such as multiple user codes, scheduled access, or connecting to an existing home system.

Why San Marino chooses us

  • Fully mobile and available 24/7, so installations and urgent lock problems are handled at your property instead of requiring a trip anywhere.
  • Operating since 1987 under owner David Shar, with deep experience on older doors and original hardware.
  • Respect for period homes: we try to preserve vintage brass and solid-wood doors instead of defaulting to cutting and replacing.
  • Honest recommendations, including telling you when a smart lock is not the right fit for a specific door.
  • Combined services in one visit, including rekeying, high-security cylinders and deadbolt upgrades alongside smart lock setup.
  • We stay to walk you through codes, batteries and overrides so you are comfortable using the system.

Smart Lock Installation across San Marino

San Marino's housing stock shapes almost every smart lock job we see. Around the Huntington Library district, many homes are large 1920s and 1930s estates with original mortise locks and heavy wood doors. There, we often pair discreet keyless entry on a secondary door with a careful rekey or high-security cylinder on the main entry, keeping the original hardware in place where possible.

In the Lacy Park neighborhood, owners frequently ask about managing access for household staff, landscapers and contractors. Unique codes that can be changed after a staff change are far easier than collecting keys, and we can also rekey exterior doors and garden or side gates so everything is consistent. Homes along Huntington Drive, Sierra Madre Blvd, San Gabriel Blvd, Del Mar Ave and Los Robles Ave all vary, so we evaluate each entry on its own.

We serve the 91108 ZIP code and the nearby Mission District along Huntington Drive, including small neighborhood-scale businesses that want keypad entry for back doors or storage areas. Wherever you are in San Marino, call (323) 997-8867 and we will come to you.

Smart Lock Installation in San Marino — FAQs

Can a smart lock be installed on an original 1920s San Marino door?
Often yes, but it depends on the door and hardware. Some doors can take a retrofit smart deadbolt, while others with original mortise hardware are better kept as is with a smart lock on a secondary door. We assess before drilling. Call (323) 997-8867 to discuss your door.
Will you keep my original brass hardware?
Whenever practical, yes. We can often add a high-security cylinder or a separate smart deadbolt while leaving vintage handles and plates in place, so the entry keeps its period character.
Do you offer smart lock installation at night or on weekends?
We are available 24/7 and fully mobile, so you can call any time. For planned installations you can schedule a convenient visit. Reach us at (323) 997-8867.
Can I give temporary codes to staff or contractors?
Many keypad and smart locks support multiple or scheduled codes. We set them up during installation and show you how to add, change or delete them, which is helpful after a staff change.
What happens if the batteries die or my phone is lost?
Most smart locks give warnings before batteries run out and include a backup such as a mechanical key, keypad code or external power option. We explain the override for your specific lock during setup.
Can you install smart locks on side doors and garden gates?
Yes, where the gate or door and hardware are suitable. Many large San Marino properties have several access points, and we can make them consistent, including rekeying others to a single key.
Can you fix a smart lock I already own?
We troubleshoot existing smart, keyless and keypad locks, including alignment problems, code resets and setup issues. If a replacement is better, we explain why. Call (323) 997-8867.
Do I need a smart lock, or is a high-security rekey enough?
It depends on your priorities. A rekey or high-security cylinder improves key control, while a smart lock adds code-based access. Many owners combine them. We help you decide without pushing extras.
