San Marino is known for its quiet streets and period-revival estates, but it also has a small, carefully kept business community. Along Huntington Drive and the Mission Street stretch of the Mission District you find professional offices, boutiques, salons, medical and financial suites, and service businesses. Each one has doors, keys and records worth protecting, and each one tends to want that protection to be effective without being intrusive.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are fully mobile. There is no storefront to visit; we bring the tools and hardware to your building, whether that is a street-front shop or a back-office suite, and we work around your business hours, including after closing.

Commercial locksmith work in a city like San Marino is rarely about volume. It is about doing the job cleanly: rekeying after an employee leaves, replacing a worn storefront cylinder, fitting a commercial-grade deadbolt, servicing a panic bar, or setting up a master key system that makes sense for a small office. We aim to explain the options plainly so you can decide what fits your building and budget.

How it works in San Marino

  1. 1

    Call and describe the situation

    Phone (323) 997-8867 any time, day or night. Tell us what type of business you have, which doors are involved, and what happened, such as a lost key, a departing employee, a failed lock, or a break-in attempt.

  2. 2

    Review the doors and hardware on site

    We come to your location and look at the actual hardware: storefront cylinders, deadbolts, mortise locks, panic devices, and any back or alley doors. We note what is worn, what is outdated, and what is fine as it stands.

  3. 3

    Recommend options in plain terms

    We explain the choices, for example rekeying versus replacing, standard versus high-security cylinders, or keyed versus electronic access. You decide before work begins, and we do not push upgrades you do not need.

  4. 4

    Complete the work on the spot

    Most rekeys, repairs and installs are done at your door with the tools we carry. We keep the work tidy, test every lock and key, and make sure doors close and latch smoothly.

  5. 5

    Hand over keys and a simple key plan

    We give you working keys and, if relevant, suggest how to track who holds them. For multi-tenant or multi-door sites, we can help set up a master key or keyed-alike arrangement.

What affects the price

  • The type of work: rekeying existing locks differs from replacing hardware or installing new devices.
  • The grade and type of hardware, such as standard commercial deadbolts versus high-security cylinders or panic devices.
  • The number of doors, cylinders and keys involved, including back doors, gates and interior offices.
  • Whether you want electronic or keyless access, which adds components and setup time.
  • The time of the call, since after-hours and overnight emergencies involve different scheduling than a planned daytime visit.
  • Condition of the existing doors and frames, since damage from forced entry or wear may need repair along with the lock.

Why San Marino chooses us

  • Fully mobile service, so we work at your business rather than asking you to bring anything anywhere.
  • Operating since 1987, which means decades of experience with older mortise hardware as well as modern commercial systems.
  • Owner-led by David Shar, so the standards for the work come from the person whose name is on the business.
  • Available 24/7, so a lock problem at closing time or overnight does not have to wait until morning.
  • Discretion suited to San Marino, where businesses prefer clean, low-profile hardware that fits the look of the street.
  • Straightforward recommendations: we tell you when a repair or rekey will do the job instead of a full replacement.

Commercial Locksmith across San Marino

San Marino's commercial life is concentrated and understated. The Mission District along Huntington Drive and Mission Street holds many of the city's small offices and shops, in the 91108 ZIP code, and we service those doors regularly in concept: storefront cylinders, rear service entrances, and suites that share a building with other tenants. Closer to the Huntington Library district, the setting is quieter still, and businesses and professional offices nearby tend to value hardware that is secure but visually restrained.

We also work with the Lacy Park neighborhood in mind, where owners of nearby offices, home-based practices and estate-related businesses often want the same level of care they give their properties. Many older buildings around the city have original mortise locks and solid-wood doors. Where that applies, we can preserve vintage brass hardware while adding a high-security cylinder, so the building keeps its character and gains real protection.

Because we are mobile, getting to you along Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue or Los Robles Avenue is part of the job. Whether you are near Crowell Public Library, the Old Mill at El Molino Viejo, or elsewhere in town, call (323) 997-8867 and we will come to your door, day or night.

Commercial Locksmith in San Marino — FAQs

Do you offer commercial locksmith service in San Marino at night?
Yes. We are available 24/7 and fully mobile, so you can call (323) 997-8867 at any hour for a lockout, a broken lock or a security concern at your business.
Can you rekey my office after an employee leaves?
Yes. Rekeying changes the internal pins so old keys no longer work, without replacing the hardware. It is a common and cost-conscious way to restore control over who has access.
Do you work on older mortise locks?
Yes. Many San Marino buildings, including some commercial spaces, have original mortise hardware. We can service it, preserve vintage brass, and add a high-security cylinder where appropriate.
Can you set up a master key system?
Yes. For offices or multi-tenant buildings, a master key system lets certain keys open multiple doors while others open only one. We can talk through what suits your layout.
Do you install panic bars and commercial deadbolts?
We install and service commercial-grade deadbolts and panic or exit hardware. Call (323) 997-8867 to describe your doors and we can advise on options.
Do I need to visit a shop to get keys?
No. Crenshaw Lock Company is mobile only. We come to your business with the equipment needed, and there is no storefront to visit.
How is the price determined?
It depends on the type of work, the hardware grade, the number of doors and keys, whether electronic access is involved, and when the call happens. We explain the options before starting.
Can you help after a break-in attempt?
Yes. We can assess damaged locks, doors and frames, repair or replace what is needed, and secure the premises. Call (323) 997-8867 any time.
