San Marino is not a city that looks like a typical commercial market. It is almost entirely residential, with period-revival estates on large lots and a modest, neighborhood-scale stretch of businesses along Huntington Drive and Mission Street. That shapes access control here. Offices, professional suites, clinics, and small shops tend to occupy older or carefully maintained buildings, where a system needs to work reliably without wrecking the character of a door or frontage.

Access control replaces the shared metal key with something you can manage. A keypad lets you assign individual codes. Cards and fobs can be issued to each employee and shut off the day someone leaves, with no rekeying of the whole building. For a business with staff turnover, cleaners, contractors, or several tenants, that control is the real value, along with a clearer picture of who is coming and going where the system supports it.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and owner and lead technician David Shar built the business on practical, honest locksmith work. We are mobile only, with no storefront, so every consultation and installation happens at your building. We are available around the clock, which matters when a door has to be secured after hours or a system fails on a busy morning.

How it works in San Marino

  1. 1

    Walk the entrances and talk through how you operate

    We start at your doors. We look at which entrances need control, how many people use them, who needs access at what times, and how the door is built. A glass storefront, a solid wood door in an older building, and a rear service door each call for different hardware.

  2. 2

    Choose the right credential type

    Keypads suit small teams and shared codes that change. Cards and fobs suit larger groups or situations where you want to cancel one person's access without affecting others. We explain the tradeoffs plainly and recommend what fits, not the most complicated option.

  3. 3

    Select compatible locking hardware

    Access control only works if the lock is right for the door. We consider electrified strikes, electric locks, and keypad or card-reader locksets, along with fire-egress needs, door frame condition, and how the door closes and latches.

  4. 4

    Install and wire or mount the system

    We mount readers or keypads, fit the locking hardware, and complete the connections needed for the system you chose. In older or character buildings we work to keep modifications neat and limit visible changes to the door and frame.

  5. 5

    Program users and test thoroughly

    We set up codes, cards, or fobs, test every credential, and check that the door locks and releases correctly, including from the inside. We confirm that free egress is never compromised.

  6. 6

    Walk you through managing it

    We show you how to add and remove users, change codes, and handle a lost card. You leave knowing how to run the system day to day, and you can call (323) 997-8867 if anything needs adjusting later.

What affects the price

  • The number of doors you want controlled, since each entrance needs its own reader or keypad and locking hardware.
  • The type of system: a standalone keypad lock is a very different scope from card or fob readers with a shared controller.
  • Door and frame condition, including whether an older wood, metal, or glass door needs preparation or reinforcement.
  • Wiring and power needs, which depend on the building layout and how far the hardware sits from a power source.
  • The number of users and credentials you need issued at setup, and how often they will change.
  • Whether the install is routine or needs after-hours or urgent attention to secure an entrance.

Why San Marino chooses us

  • Fully mobile service: we come to your San Marino business and work on your actual doors rather than selling from a catalog.
  • In business since 1987, with David Shar as owner and lead technician guiding the work.
  • Available 24/7, so a failed reader or an unsecured door does not have to wait for business hours.
  • We match hardware to the door, including older frames and solid-wood doors, rather than forcing one product everywhere.
  • Straightforward recommendations: if a simple keypad does the job, we will not push a larger system.
  • We can also handle rekeying and high-security cylinders, so your mechanical backup keys and your electronic access can be planned together.

Access Control across San Marino

San Marino's commercial life is small and concentrated, mostly along Huntington Drive and the Mission Street area in the Mission District, with professional offices and neighborhood businesses that sit close to a very residential city. Many of these buildings share the period character that defines San Marino, so a good access-control install here is quiet and tidy rather than industrial. We work with that, keeping hardware discreet and respecting the door you already have.

The city's institutions set its tone. Around the Huntington Library district, the Lacy Park neighborhood, and near spots like Crowell Public Library and El Molino Viejo, people expect careful, well-kept properties. Businesses and offices serving that community, within ZIP code 91108, often want the security benefits of keypads, cards, or fobs without altering how an entrance looks. We will talk through placement and finish before we drill anything.

We reach San Marino by way of Huntington Drive, Sierra Madre Boulevard, San Gabriel Boulevard, Del Mar Avenue, and Los Robles Avenue, and we are available at any hour. Because owners here often also care about residential security, we can discuss mechanical rekeying and high-security cylinders alongside your access control. Call (323) 997-8867 to start.

Access Control in San Marino — FAQs

What types of access control do you install in San Marino?
We install keypad, card, and fob systems for business entrances. We help you choose among them based on your doors, your team size, and how often access changes. Call (323) 997-8867 to discuss your situation.
Can you install access control on an older building along Huntington Drive?
Yes. We look at the door, frame, and surrounding wall first and choose hardware that fits. Older wood or character doors may need extra care, and we aim to keep changes neat and limited.
Do you have a shop I can visit?
No. Crenshaw Lock Company is fully mobile, with no storefront. We come to your business in San Marino and do the consultation and installation on site.
Is keypad or fob access better for my business?
It depends. Keypads are simple and good for small groups. Cards and fobs let you cancel one person's access without affecting anyone else, which helps with staff turnover. We will recommend what fits.
Will access control stop me from exiting quickly in an emergency?
Egress must always remain safe. We design and test installations so the door releases properly from the inside, and we check this before we finish.
Can you help if my existing system stops working after hours?
We are available 24/7. Call (323) 997-8867 and we will work out how to get your entrance secured and functioning again.
What affects the cost of an access control installation?
Mainly the number of doors, the type of system, door and frame condition, wiring needs, and how many users you need set up. We explain these factors when we look at your entrances.
Can you also rekey the mechanical locks at the same time?
Yes. We can rekey or upgrade the mechanical cylinders as part of the same visit, so your backup keys and your electronic access work together under a plan that suits your business.
