A master key system lets one key open many doors while each person carries only what they need. A tenant gets a key for their suite, a floor manager gets a key for every suite on that floor, and the building owner holds a key that opens everything. Done well, it cuts down the key ring, makes turnover simple, and gives you a clear record of who can go where. Done poorly, it creates overlapping keys, security gaps, and a mess that is expensive to untangle.

Culver City is a good example of why planning matters. Within a few miles you have production offices and tech tenants in the Hayden Tract and downtown, aluminum-storefront retail along Washington and Culver Boulevards, large condo and apartment buildings in Fox Hills, and older buildings with original hardware. Each one needs a different hierarchy, a different level of key control, and sometimes a different cylinder brand or an electronic access layer.

Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, led by owner and lead technician David Shar. We are mobile only, so there is no storefront to visit. We come to you, walk the property, and build the system around how your site actually operates.

How it works in Culver City

  1. 1

    Walk the property and talk through access

    We come to your Culver City site and look at every door, lock, and cylinder type. We ask who needs access to what, which areas are sensitive, how often staff or tenants change, and whether you already have electronic access control that the mechanical system should work alongside.

  2. 2

    Design the key hierarchy

    We map out the levels: individual change keys, group or floor masters, and a grand master, with a possible great-grand master for larger sites. We explain the tradeoffs, since every added level adds some complexity and a small amount of security exposure, so the design stays only as complicated as it needs to be.

  3. 3

    Choose the right hardware and key control level

    For a standard office, a conventional master-key-capable cylinder may be enough. For studios, tech tenants, or sites worried about unauthorized copying, we can discuss restricted keyways and high-security cylinders such as Medeco or Schlage Primus, where keys can only be duplicated through authorized channels.

  4. 4

    Install, rekey, and pin the system

    We install or rekey cylinders on site so they all follow the design, and check that every key opens only what it should. Existing doors with mismatched or worn hardware are flagged, so you are not building a good system on a failing lock.

  5. 5

    Test, document, and hand over

    We test each key against each door and give you a clear record of the hierarchy and key assignments. We also talk through how to issue, track, and recover keys so the system stays controlled after we leave.

  6. 6

    Expand or adjust later

    Tenants move out, floors get reorganized, and buildings grow. A well-documented system can be extended or re-keyed in sections without starting over, and we are available around the clock if something urgent comes up.

What affects the price

  • The number of doors and cylinders in the system, and whether any existing hardware must be replaced rather than rekeyed.
  • How many levels the hierarchy has, from simple change keys and one master up to grand master or beyond.
  • The security level you choose, such as standard cylinders versus restricted keyways or high-security brands like Medeco or Schlage Primus.
  • Whether the system must coordinate with electronic access control, card readers, or other existing hardware.
  • How many keys you need cut, and whether they are patent-protected or otherwise restricted from casual duplication.
  • Timing and site conditions, including after-hours work to avoid disrupting tenants, studios, or businesses.

Why Culver City chooses us

  • Fully mobile and available 24/7, so work can happen after hours when an office or studio is empty.
  • Serving the Los Angeles area since 1987, with experience across offices, apartment buildings, retail, and older properties.
  • Owner-led: David Shar is the lead technician, so the person who plans your system understands it.
  • Design comes first. We build the hierarchy around how your site operates instead of selling a standard package.
  • Honest about tradeoffs, including when a simpler system or a hardware upgrade makes more sense than a complex one.
  • Clear documentation so you can manage keys yourself afterward.

Master Key System across Culver City

Culver City's mix of buildings makes master key work very site-specific. In the Hayden Tract and downtown near Washington Boulevard, production offices and tech tenants often want restricted keys and high-security cylinders, sometimes paired with electronic access, so contractors, staff, and facilities teams each get the right level of entry. Around the Helms Bakery District, The Culver Steps, and the Culver Hotel, mixed-use and commercial properties often have many tenants who need separate keys, with management holding a master.

In Fox Hills, the larger 1970s and 80s condo and apartment buildings near Sepulveda Boulevard and the I-405 benefit from a system that makes tenant turnover easier. Property managers can rekey a unit between residents without reissuing keys to the whole building, and maintenance staff can carry a single key for common areas. We coordinate with property management so the work fits around residents.

Older properties in Carlson Park and Sunkist Park, many with original mortise hardware, need care, since not every vintage lock accepts a master-key setup and we will tell you honestly what can be adapted. We work across ZIP codes 90230 and 90232, from Culver Crest and Blair Hills down to the Ballona Creek corridor. Call (323) 997-8867 any time to talk it through.

Master Key System in Culver City — FAQs

What is a master key system?
It is a lock setup where each door has its own key, while higher-level keys open groups of doors or the entire building. It lets managers carry one key instead of many while tenants or staff only open their own spaces.
Can you set up a master key system for an office or studio in Culver City?
Yes. We are mobile and come to your site, whether in the Hayden Tract, downtown, or elsewhere in the city. Call (323) 997-8867 to describe the property and set up a walkthrough.
What is a restricted key system?
A restricted system uses keyways and keys that cannot be freely duplicated at a typical hardware store. Copies require authorization, which helps you control who holds keys. High-security options such as Medeco and Schlage Primus are common choices.
Can a master key system work with electronic access control?
Often, yes. Many sites use electronic access for main entries and mechanical master-key cylinders for suites, closets, and back-of-house doors. We review what you have and design the two to complement each other.
Can my existing locks be converted to a master key system?
Sometimes. Many modern cylinders can be re-pinned for a master system, but some older or low-quality hardware cannot, and certain vintage mortise locks may need special handling. We check during the walkthrough and tell you what is practical.
Is a master key system a good idea for apartment buildings in Fox Hills?
It can be, especially for turnover. Managers can rekey one unit without affecting others, and staff can access common areas with limited keys. We coordinate with property management. Call (323) 997-8867 to discuss your building.
Are you available after hours or on weekends?
Yes, we operate 24/7 and are fully mobile. Many businesses prefer after-hours installation so there is no disruption to staff or tenants.
How do I keep control of keys once the system is installed?
We provide documentation of the hierarchy and suggest practices for issuing and tracking keys. Restricted keyways add another layer, since copies cannot be easily made without authorization.
