A master key system lets the right people open the right doors with the fewest keys possible. A property manager may carry one key that opens every suite, a tenant carries one that opens only theirs, and a maintenance crew carries one for service areas. Done well, it cuts down the key ring, makes tenant turnover simpler, and gives you a record of who holds what. Done badly, it leaves you with cross-keying surprises and keys no one can account for.

Westlake Village has plenty of places where this matters. The business district has corporate office parks and aluminum-storefront retail where tenants come and go. Condo and townhome communities have HOA-managed common locks, mailboxes, pool gates and utility rooms. Larger gated estates on and around Westlake Island may want a single hierarchy for house, guest quarters, gate and boathouse. Each of these calls for a different layout.

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, with no storefront, so we do the planning and the work at your property. We start by understanding your doors and your people, and only then do we design the hierarchy.

How it works in Westlake Village

  1. 1

    Walk the property and list every opening

    We come to your site and inventory the doors, gates, cabinets, mailboxes and utility rooms involved. We note which locks can be pinned into a system and which hardware, such as older or mismatched cylinders, should be replaced first.

  2. 2

    Map who needs access to what

    Together we sort users into levels: grand master, master, and individual change keys. For an office park that might be building management, suite tenants and cleaning crews. For an HOA it might be the board, the landscaper and the pool service.

  3. 3

    Design the hierarchy and choose key control

    We lay out the keying chart on paper before any pin is touched, with room for growth. We also discuss restricted keyways, which prevent copies from being cut at a hardware kiosk, and how authorization for new keys will work.

  4. 4

    Install, rekey and test every lock

    We rekey or replace cylinders to match the chart, then test each key against every lock it should and should not open. Mistakes in a master system show up at this stage, so we check carefully.

  5. 5

    Hand over keys and records

    You receive the keys, a clear explanation of the chart, and guidance on keeping records of who holds what. We can also advise on tenant turnover, so a departing tenant's key stops working without rekeying the whole building.

  6. 6

    Expand or adjust later

    Because the system was charted from the start, adding a suite, a new tenant or another gate is straightforward. Call us when your needs change and we will work from the existing chart.

What affects the price

  • The number of doors, gates and other openings that need to be included in the system.
  • How many levels the hierarchy has, since more levels and more distinct users make for a more involved design.
  • Whether existing hardware can be rekeyed or needs replacing with cylinders that accept a master system.
  • Whether you want a restricted keyway with patent-style key control, versus a standard keyway system.
  • How many keys must be cut at each level, and whether keys need to be stamped or tracked.
  • Whether the project ties into access control, smart locks or gate and intercom hardware, and the scheduling needs of an occupied building.

Why Westlake Village chooses us

  • Mobile only: we work at your office, community or estate rather than asking you to bring locks to a shop.
  • In business since 1987, with the owner, David Shar, directly involved rather than handing everything off.
  • We design the chart on paper first, so expansion and tenant turnover are planned rather than patched in later.
  • We are comfortable with both commercial hardware and residential mixes like HOA common areas, smart locks and gates.
  • We will tell you honestly when a simpler rekey does the job and a full master system is not needed.
  • 24/7 availability means that if a key goes missing or a tenant leaves abruptly, you can call at any hour.

Master Key System across Westlake Village

Westlake Village sits at the Los Angeles and Ventura County line, and the work here reflects that mix. Around the business district near US-101, Lindero Canyon Road and Westlake Blvd, office parks often need a master rekey after a tenant turnover, with access control updated to match. Retail around The Promenade and The Shoppes at Westlake Village typically uses aluminum storefront doors, which have their own hardware limits we plan around.

Residential and HOA properties have different needs. Townhome communities near The Promenade often want common-area doors and mailbox locks put on one hierarchy that the board controls. In First Neighborhood and Three Springs, master-planned communities from the 1970s and 80s may have aging common hardware that is worth reviewing before it is keyed into a system. On Westlake Island, lakefront homes with private docks and gates may want a coordinated setup, and lake air can wear on exterior hardware, so we check condition before pinning cylinders.

We serve addresses across ZIP codes 91361, 91362 and 91359, which Westlake Village shares with Thousand Oaks, so please confirm your address when you call (323) 997-8867. We come to you at any hour, whether you are near Agoura Road, Thousand Oaks Blvd or Westlake Lake.

Master Key System in Westlake Village — FAQs

What is a master key system?
It is a keying layout where each lock has its own key, and higher-level keys open groups of locks. A building manager may hold a key that opens every suite, while a tenant holds one for a single suite. Call (323) 997-8867 to talk through a layout.
Do you offer master key systems for Westlake Village office parks?
Yes. We handle master rekeys after tenant turnover and can coordinate with access control updates. We are mobile, so we come to your building and work around occupied suites.
Can an HOA put common-area locks and mailboxes on a master system?
Yes. Townhome and condo communities often want gates, pool doors, utility rooms and mailboxes on one hierarchy controlled by the board. We chart who needs access first, then rekey to match.
What is a restricted key and do I need one?
A restricted keyway uses a key blank that is not freely sold, so copies cannot be made casually. It adds key control for properties where duplicate keys are a real concern. We can tell you whether it fits your situation.
Can you add to a master key system later?
Usually yes, if the system was charted properly. We work from the existing chart to add doors, suites or levels. Call (323) 997-8867 and have any existing key records ready.
What happens when a tenant leaves or a key is lost?
Depending on the design, we can often rekey just the affected suite so the old key stops working without touching the whole building. A good chart makes this much simpler.
Do you work with smart locks and gates in a system?
We can work alongside smart locks and gate or intercom hardware, though electronic components are managed separately from the mechanical keying. We will explain how the pieces fit together.
Do you have a shop I can visit?
No. We are fully mobile and available 24/7, so we come to your Westlake Village property. Phone us at (323) 997-8867 to arrange a visit.
